slash travis roman before we jump into that though there is 44 00:00:49,590 --> 00:00:49,600 before we jump into that though there is 45 00:00:49,600 --> 00:00:50,470 before we jump into that though there is one 46 00:00:50,470 --> 00:00:50,480 one 47 00:00:50,480 --> 00:00:52,790 one minor thing that i would like to enhance 48 00:00:52,790 --> 00:00:52,800 minor thing that i would like to enhance 49 00:00:52,800 --> 00:00:55,270 minor thing that i would like to enhance with our logger so 50 00:00:55,270 --> 00:00:55,280 with our logger so 51 00:00:55,280 --> 00:00:57,670 with our logger so in the last video we actually added our 52 00:00:57,670 --> 00:00:57,680 in the last video we actually added our 53 00:00:57,680 --> 00:01:00,470 in the last video we actually added our file system which was a 54 00:01:00,470 --> 00:01:00,480 file system which was a 55 00:01:00,480 --> 00:01:01,750 file system which was a component that we were missing to be 56 00:01:01,750 --> 00:01:01,760 component that we were missing to be 57 00:01:01,760 --> 00:01:03,590 component that we were missing to be able to actually write out our logging 58 00:01:03,590 --> 00:01:03,600 able to actually write out our logging 59 00:01:03,600 --> 00:01:06,630 able to actually write out our logging files so writing out your logs to a file 60 00:01:06,630 --> 00:01:06,640 files so writing out your logs to a file 61 00:01:06,640 --> 00:01:08,710 files so writing out your logs to a file is a great way to be able to debug 62 00:01:08,710 --> 00:01:08,720 is a great way to be able to debug 63 00:01:08,720 --> 00:01:10,550 is a great way to be able to debug crashes so if you're running the 64 00:01:10,550 --> 00:01:10,560 crashes so if you're running the 65 00:01:10,560 --> 00:01:12,070 crashes so if you're running the application and for some reason it just 66 00:01:12,070 --> 00:01:12,080 application and for some reason it just 67 00:01:12,080 --> 00:01:13,910 application and for some reason it just crashes on you 68 00:01:13,910 --> 00:01:13,920 crashes on you 69 00:01:13,920 --> 00:01:15,749 crashes on you it's one way to be able to 70 00:01:15,749 --> 00:01:15,759 it's one way to be able to 71 00:01:15,759 --> 00:01:18,310 it's one way to be able to debug the application so 72 00:01:18,310 --> 00:01:18,320 debug the application so 73 00:01:18,320 --> 00:01:20,550 debug the application so particularly if you're not running in 74 00:01:20,550 --> 00:01:20,560 particularly if you're not running in 75 00:01:20,560 --> 00:01:23,030 particularly if you're not running in debug mode you might want to actually be 76 00:01:23,030 --> 00:01:23,040 debug mode you might want to actually be 77 00:01:23,040 --> 00:01:25,429 debug mode you might want to actually be able to examine your log file so 78 00:01:25,429 --> 00:01:25,439 able to examine your log file so 79 00:01:25,439 --> 00:01:26,789 able to examine your log file so we're going to go ahead and put that in 80 00:01:26,789 --> 00:01:26,799 we're going to go ahead and put that in 81 00:01:26,799 --> 00:01:28,230 we're going to go ahead and put that in real quick it's actually pretty 82 00:01:28,230 --> 00:01:28,240 real quick it's actually pretty 83 00:01:28,240 --> 00:01:29,590 real quick it's actually pretty straightforward so let's go ahead and 84 00:01:29,590 --> 00:01:29,600 straightforward so let's go ahead and 85 00:01:29,600 --> 00:01:31,270 straightforward so let's go ahead and knock it out real quick 86 00:01:31,270 --> 00:01:31,280 knock it out real quick 87 00:01:31,280 --> 00:01:32,630 knock it out real quick first thing we're going to do is we're 88 00:01:32,630 --> 00:01:32,640 first thing we're going to do is we're 89 00:01:32,640 --> 00:01:37,270 first thing we're going to do is we're going to include platform filesystem.h 90 00:01:37,270 --> 00:01:37,280 91 00:01:37,280 --> 00:01:39,670 and next in the log system state we're 92 00:01:39,670 --> 00:01:39,680 and next in the log system state we're 93 00:01:39,680 --> 00:01:41,830 and next in the log system state we're going to get rid of this rubbish 94 00:01:41,830 --> 00:01:41,840 going to get rid of this rubbish 95 00:01:41,840 --> 00:01:43,590 going to get rid of this rubbish initialized property because we don't 96 00:01:43,590 --> 00:01:43,600 initialized property because we don't 97 00:01:43,600 --> 00:01:45,670 initialized property because we don't actually need it or use it 98 00:01:45,670 --> 00:01:45,680 actually need it or use it 99 00:01:45,680 --> 00:01:46,389 actually need it or use it so 100 00:01:46,389 --> 00:01:46,399 so 101 00:01:46,399 --> 00:01:49,109 so that is going to go bye-bye 102 00:01:49,109 --> 00:01:49,119 that is going to go bye-bye 103 00:01:49,119 --> 00:01:51,830 that is going to go bye-bye and we are going to instead 104 00:01:51,830 --> 00:01:51,840 and we are going to instead 105 00:01:51,840 --> 00:01:53,030 and we are going to instead create a 106 00:01:53,030 --> 00:01:53,040 create a 107 00:01:53,040 --> 00:01:55,510 create a new file or wipe an existing file if it 108 00:01:55,510 --> 00:01:55,520 new file or wipe an existing file if it 109 00:01:55,520 --> 00:01:57,030 new file or wipe an existing file if it exists 110 00:01:57,030 --> 00:01:57,040 exists 111 00:01:57,040 --> 00:01:59,030 exists our 112 00:01:59,030 --> 00:01:59,040 our 113 00:01:59,040 --> 00:02:00,870 our log file okay so we're just going to say 114 00:02:00,870 --> 00:02:00,880 log file okay so we're just going to say 115 00:02:00,880 --> 00:02:02,310 log file okay so we're just going to say file system open 116 00:02:02,310 --> 00:02:02,320 file system open 117 00:02:02,320 --> 00:02:04,389 file system open and we're going to call this console.log 118 00:02:04,389 --> 00:02:04,399 and we're going to call this console.log 119 00:02:04,399 --> 00:02:06,069 and we're going to call this console.log we're going to use the dot log extension 120 00:02:06,069 --> 00:02:06,079 we're going to use the dot log extension 121 00:02:06,079 --> 00:02:07,990 we're going to use the dot log extension so that vs code can actually pick up on 122 00:02:07,990 --> 00:02:08,000 so that vs code can actually pick up on 123 00:02:08,000 --> 00:02:09,990 so that vs code can actually pick up on some highlighting for that 124 00:02:09,990 --> 00:02:10,000 some highlighting for that 125 00:02:10,000 --> 00:02:11,750 some highlighting for that it is not going to be in binary mode it 126 00:02:11,750 --> 00:02:11,760 it is not going to be in binary mode it 127 00:02:11,760 --> 00:02:14,550 it is not going to be in binary mode it is only going to be in write mode 128 00:02:14,550 --> 00:02:14,560 is only going to be in write mode 129 00:02:14,560 --> 00:02:16,470 is only going to be in write mode and we are just going to store this in 130 00:02:16,470 --> 00:02:16,480 and we are just going to store this in 131 00:02:16,480 --> 00:02:18,869 and we are just going to store this in the log file handle 132 00:02:18,869 --> 00:02:18,879 the log file handle 133 00:02:18,879 --> 00:02:22,390 the log file handle and if for some reason we cannot do this 134 00:02:22,390 --> 00:02:22,400 and if for some reason we cannot do this 135 00:02:22,400 --> 00:02:24,150 and if for some reason we cannot do this that indicates some problem that we 136 00:02:24,150 --> 00:02:24,160 that indicates some problem that we 137 00:02:24,160 --> 00:02:25,750 that indicates some problem that we actually need to investigate and fix at 138 00:02:25,750 --> 00:02:25,760 actually need to investigate and fix at 139 00:02:25,760 --> 00:02:27,270 actually need to investigate and fix at the engine level 140 00:02:27,270 --> 00:02:27,280 the engine level 141 00:02:27,280 --> 00:02:29,110 the engine level or the file system level and so we are 142 00:02:29,110 --> 00:02:29,120 or the file system level and so we are 143 00:02:29,120 --> 00:02:31,589 or the file system level and so we are actually going to abort uh 144 00:02:31,589 --> 00:02:31,599 actually going to abort uh 145 00:02:31,599 --> 00:02:32,869 actually going to abort uh the logging 146 00:02:32,869 --> 00:02:32,879 the logging 147 00:02:32,879 --> 00:02:34,710 the logging initialization if we cannot write that 148 00:02:34,710 --> 00:02:34,720 initialization if we cannot write that 149 00:02:34,720 --> 00:02:37,350 initialization if we cannot write that file okay 150 00:02:37,350 --> 00:02:37,360 file okay 151 00:02:37,360 --> 00:02:38,390 file okay all right 152 00:02:38,390 --> 00:02:38,400 all right 153 00:02:38,400 --> 00:02:39,430 all right so 154 00:02:39,430 --> 00:02:39,440 so 155 00:02:39,440 --> 00:02:40,949 so one other thing that we are going to 156 00:02:40,949 --> 00:02:40,959 one other thing that we are going to 157 00:02:40,959 --> 00:02:43,110 one other thing that we are going to need the ability to do 158 00:02:43,110 --> 00:02:43,120 need the ability to do 159 00:02:43,120 --> 00:02:43,910 need the ability to do is 160 00:02:43,910 --> 00:02:43,920 is 161 00:02:43,920 --> 00:02:45,830 is we are going to need the ability to 162 00:02:45,830 --> 00:02:45,840 we are going to need the ability to 163 00:02:45,840 --> 00:02:48,070 we are going to need the ability to append to a log file so i'm just going 164 00:02:48,070 --> 00:02:48,080 append to a log file so i'm just going 165 00:02:48,080 --> 00:02:49,030 append to a log file so i'm just going to put a 166 00:02:49,030 --> 00:02:49,040 to put a 167 00:02:49,040 --> 00:02:50,869 to put a private method in here 168 00:02:50,869 --> 00:02:50,879 private method in here 169 00:02:50,879 --> 00:02:53,190 private method in here where we have a message that is passed 170 00:02:53,190 --> 00:02:53,200 where we have a message that is passed 171 00:02:53,200 --> 00:02:53,990 where we have a message that is passed in 172 00:02:53,990 --> 00:02:54,000 in 173 00:02:54,000 --> 00:02:56,150 in and so if we have a state pointer and 174 00:02:56,150 --> 00:02:56,160 and so if we have a state pointer and 175 00:02:56,160 --> 00:02:59,030 and so if we have a state pointer and the handle to the log file is valid 176 00:02:59,030 --> 00:02:59,040 the handle to the log file is valid 177 00:02:59,040 --> 00:03:01,589 the handle to the log file is valid then we are going to basically take the 178 00:03:01,589 --> 00:03:01,599 then we are going to basically take the 179 00:03:01,599 --> 00:03:04,070 then we are going to basically take the length of the string and we are going to 180 00:03:04,070 --> 00:03:04,080 length of the string and we are going to 181 00:03:04,080 --> 00:03:06,149 length of the string and we are going to write to that log file 182 00:03:06,149 --> 00:03:06,159 write to that log file 183 00:03:06,159 --> 00:03:09,270 write to that log file and uh we are going to um 184 00:03:09,270 --> 00:03:09,280 and uh we are going to um 185 00:03:09,280 --> 00:03:11,910 and uh we are going to um report if for some reason we can't write 186 00:03:11,910 --> 00:03:11,920 report if for some reason we can't write 187 00:03:11,920 --> 00:03:13,270 report if for some reason we can't write to the file we're going to report to the 188 00:03:13,270 --> 00:03:13,280 to the file we're going to report to the 189 00:03:13,280 --> 00:03:15,830 to the file we're going to report to the console that there's been error writing 190 00:03:15,830 --> 00:03:15,840 console that there's been error writing 191 00:03:15,840 --> 00:03:17,910 console that there's been error writing to that but basically this is just a a 192 00:03:17,910 --> 00:03:17,920 to that but basically this is just a a 193 00:03:17,920 --> 00:03:19,430 to that but basically this is just a a way for us to be able to quickly and 194 00:03:19,430 --> 00:03:19,440 way for us to be able to quickly and 195 00:03:19,440 --> 00:03:21,990 way for us to be able to quickly and easily write to the log file so now that 196 00:03:21,990 --> 00:03:22,000 easily write to the log file so now that 197 00:03:22,000 --> 00:03:23,430 easily write to the log file so now that we have that in place 198 00:03:23,430 --> 00:03:23,440 we have that in place 199 00:03:23,440 --> 00:03:25,400 we have that in place we just need to hook up this method 200 00:03:25,400 --> 00:03:25,410 we just need to hook up this method 201 00:03:25,410 --> 00:03:27,670 we just need to hook up this method [Music] 202 00:03:27,670 --> 00:03:27,680 [Music] 203 00:03:27,680 --> 00:03:30,309 [Music] and all that entails is just going to 204 00:03:30,309 --> 00:03:30,319 and all that entails is just going to 205 00:03:30,319 --> 00:03:32,470 and all that entails is just going to the end of log 206 00:03:32,470 --> 00:03:32,480 the end of log 207 00:03:32,480 --> 00:03:33,509 the end of log output 208 00:03:33,509 --> 00:03:33,519 output 209 00:03:33,519 --> 00:03:35,990 output and tacking that at the bottom 210 00:03:35,990 --> 00:03:36,000 and tacking that at the bottom 211 00:03:36,000 --> 00:03:37,910 and tacking that at the bottom so all we do is just append to the log 212 00:03:37,910 --> 00:03:37,920 so all we do is just append to the log 213 00:03:37,920 --> 00:03:39,910 so all we do is just append to the log file the out message that we've already 214 00:03:39,910 --> 00:03:39,920 file the out message that we've already 215 00:03:39,920 --> 00:03:41,750 file the out message that we've already built here 216 00:03:41,750 --> 00:03:41,760 built here 217 00:03:41,760 --> 00:03:44,390 built here and that should be it 218 00:03:44,390 --> 00:03:44,400 and that should be it 219 00:03:44,400 --> 00:03:46,869 and that should be it one other thing that i would like to 220 00:03:46,869 --> 00:03:46,879 one other thing that i would like to 221 00:03:46,879 --> 00:03:50,949 one other thing that i would like to take a moment and simplify also is 222 00:03:50,949 --> 00:03:50,959 take a moment and simplify also is 223 00:03:50,959 --> 00:03:53,589 take a moment and simplify also is this logic in here because we actually 224 00:03:53,589 --> 00:03:53,599 this logic in here because we actually 225 00:03:53,599 --> 00:03:54,550 this logic in here because we actually have 226 00:03:54,550 --> 00:03:54,560 have 227 00:03:54,560 --> 00:03:56,470 have added some things to our string library 228 00:03:56,470 --> 00:03:56,480 added some things to our string library 229 00:03:56,480 --> 00:03:58,390 added some things to our string library that should actually allow us to 230 00:03:58,390 --> 00:03:58,400 that should actually allow us to 231 00:03:58,400 --> 00:04:01,110 that should actually allow us to simplify this so i'm going to go ahead 232 00:04:01,110 --> 00:04:01,120 simplify this so i'm going to go ahead 233 00:04:01,120 --> 00:04:02,470 simplify this so i'm going to go ahead and 234 00:04:02,470 --> 00:04:02,480 and 235 00:04:02,480 --> 00:04:04,710 and include 236 00:04:04,710 --> 00:04:04,720 include 237 00:04:04,720 --> 00:04:06,470 include k string 238 00:04:06,470 --> 00:04:06,480 k string 239 00:04:06,480 --> 00:04:07,990 k string and i'm actually going to get rid of 240 00:04:07,990 --> 00:04:08,000 and i'm actually going to get rid of 241 00:04:08,000 --> 00:04:11,140 and i'm actually going to get rid of string.h and stdio 242 00:04:11,140 --> 00:04:11,150 string.h and stdio 243 00:04:11,150 --> 00:04:18,870 string.h and stdio [Music] 244 00:04:18,870 --> 00:04:18,880 [Music] 245 00:04:18,880 --> 00:04:20,870 [Music] and i'm basically going to replace this 246 00:04:20,870 --> 00:04:20,880 and i'm basically going to replace this 247 00:04:20,880 --> 00:04:22,629 and i'm basically going to replace this chunk of code with something a little 248 00:04:22,629 --> 00:04:22,639 chunk of code with something a little 249 00:04:22,639 --> 00:04:24,629 chunk of code with something a little bit simpler and 250 00:04:24,629 --> 00:04:24,639 bit simpler and 251 00:04:24,639 --> 00:04:26,710 bit simpler and honestly better commented 252 00:04:26,710 --> 00:04:26,720 honestly better commented 253 00:04:26,720 --> 00:04:28,870 honestly better commented so one note i'm putting in here is a to 254 00:04:28,870 --> 00:04:28,880 so one note i'm putting in here is a to 255 00:04:28,880 --> 00:04:32,150 so one note i'm putting in here is a to do so uh string operations are generally 256 00:04:32,150 --> 00:04:32,160 do so uh string operations are generally 257 00:04:32,160 --> 00:04:33,430 do so uh string operations are generally pretty slow 258 00:04:33,430 --> 00:04:33,440 pretty slow 259 00:04:33,440 --> 00:04:34,710 pretty slow so one thing that we need to do 260 00:04:34,710 --> 00:04:34,720 so one thing that we need to do 261 00:04:34,720 --> 00:04:36,150 so one thing that we need to do eventually is split this out to a 262 00:04:36,150 --> 00:04:36,160 eventually is split this out to a 263 00:04:36,160 --> 00:04:37,670 eventually is split this out to a different thread once we have threading 264 00:04:37,670 --> 00:04:37,680 different thread once we have threading 265 00:04:37,680 --> 00:04:38,790 different thread once we have threading available 266 00:04:38,790 --> 00:04:38,800 available 267 00:04:38,800 --> 00:04:40,550 available but i want to take 268 00:04:40,550 --> 00:04:40,560 but i want to take 269 00:04:40,560 --> 00:04:43,350 but i want to take advantage of our string format 270 00:04:43,350 --> 00:04:43,360 advantage of our string format 271 00:04:43,360 --> 00:04:45,909 advantage of our string format capabilities and go ahead and utilize 272 00:04:45,909 --> 00:04:45,919 capabilities and go ahead and utilize 273 00:04:45,919 --> 00:04:47,990 capabilities and go ahead and utilize those instead so 274 00:04:47,990 --> 00:04:48,000 those instead so 275 00:04:48,000 --> 00:04:51,670 those instead so this is just a little bit cleaner 276 00:04:51,670 --> 00:04:51,680 this is just a little bit cleaner 277 00:04:51,680 --> 00:04:52,950 this is just a little bit cleaner in terms of 278 00:04:52,950 --> 00:04:52,960 in terms of 279 00:04:52,960 --> 00:04:57,590 in terms of our actual ability to log okay great so 280 00:04:57,590 --> 00:04:57,600 our actual ability to log okay great so 281 00:04:57,600 --> 00:04:59,990 our actual ability to log okay great so now that that is done we can go ahead 282 00:04:59,990 --> 00:05:00,000 now that that is done we can go ahead 283 00:05:00,000 --> 00:05:02,629 now that that is done we can go ahead and move on so let's just uh 284 00:05:02,629 --> 00:05:02,639 and move on so let's just uh 285 00:05:02,639 --> 00:05:05,670 and move on so let's just uh really quickly build 286 00:05:05,670 --> 00:05:05,680 really quickly build 287 00:05:05,680 --> 00:05:09,029 really quickly build and it looks like we have 288 00:05:09,029 --> 00:05:09,039 and it looks like we have 289 00:05:09,039 --> 00:05:10,629 and it looks like we have ah 290 00:05:10,629 --> 00:05:10,639 ah 291 00:05:10,639 --> 00:05:12,150 ah so it looks like i did not include 292 00:05:12,150 --> 00:05:12,160 so it looks like i did not include 293 00:05:12,160 --> 00:05:14,390 so it looks like i did not include memory i need to include k memory as 294 00:05:14,390 --> 00:05:14,400 memory i need to include k memory as 295 00:05:14,400 --> 00:05:15,040 memory i need to include k memory as well 296 00:05:15,040 --> 00:05:15,050 well 297 00:05:15,050 --> 00:05:16,469 well [Music] 298 00:05:16,469 --> 00:05:16,479 [Music] 299 00:05:16,479 --> 00:05:18,070 [Music] so we'll go ahead and get that in there 300 00:05:18,070 --> 00:05:18,080 so we'll go ahead and get that in there 301 00:05:18,080 --> 00:05:20,150 so we'll go ahead and get that in there let's build again 302 00:05:20,150 --> 00:05:20,160 let's build again 303 00:05:20,160 --> 00:05:21,990 let's build again and now we're good okay we'll go ahead 304 00:05:21,990 --> 00:05:22,000 and now we're good okay we'll go ahead 305 00:05:22,000 --> 00:05:23,590 and now we're good okay we'll go ahead and run 306 00:05:23,590 --> 00:05:23,600 and run 307 00:05:23,600 --> 00:05:25,670 and run just as a sanity check 308 00:05:25,670 --> 00:05:25,680 just as a sanity check 309 00:05:25,680 --> 00:05:27,029 just as a sanity check perfect so 310 00:05:27,029 --> 00:05:27,039 perfect so 311 00:05:27,039 --> 00:05:29,270 perfect so we're good as far as that goes 312 00:05:29,270 --> 00:05:29,280 we're good as far as that goes 313 00:05:29,280 --> 00:05:32,310 we're good as far as that goes okay so obviously you'll see that we got 314 00:05:32,310 --> 00:05:32,320 okay so obviously you'll see that we got 315 00:05:32,320 --> 00:05:33,670 okay so obviously you'll see that we got some 316 00:05:33,670 --> 00:05:33,680 some 317 00:05:33,680 --> 00:05:35,430 some some validation errors here and that's 318 00:05:35,430 --> 00:05:35,440 some validation errors here and that's 319 00:05:35,440 --> 00:05:37,110 some validation errors here and that's because we did not 320 00:05:37,110 --> 00:05:37,120 because we did not 321 00:05:37,120 --> 00:05:38,629 because we did not actually destroy the shader module 322 00:05:38,629 --> 00:05:38,639 actually destroy the shader module 323 00:05:38,639 --> 00:05:41,350 actually destroy the shader module before we killed everything else so 324 00:05:41,350 --> 00:05:41,360 before we killed everything else so 325 00:05:41,360 --> 00:05:43,510 before we killed everything else so first and foremost we should probably go 326 00:05:43,510 --> 00:05:43,520 first and foremost we should probably go 327 00:05:43,520 --> 00:05:45,510 first and foremost we should probably go back into our 328 00:05:45,510 --> 00:05:45,520 back into our 329 00:05:45,520 --> 00:05:46,430 back into our object shader 330 00:05:46,430 --> 00:05:46,440 object shader 331 00:05:46,440 --> 00:05:48,629 object shader [Music] 332 00:05:48,629 --> 00:05:48,639 [Music] 333 00:05:48,639 --> 00:05:50,629 [Music] and we'll actually need to fix this in 334 00:05:50,629 --> 00:05:50,639 and we'll actually need to fix this in 335 00:05:50,639 --> 00:05:52,950 and we'll actually need to fix this in two places so our object shader should 336 00:05:52,950 --> 00:05:52,960 two places so our object shader should 337 00:05:52,960 --> 00:05:55,430 two places so our object shader should actually properly destroy that 338 00:05:55,430 --> 00:05:55,440 actually properly destroy that 339 00:05:55,440 --> 00:05:58,469 actually properly destroy that so in our object shader destroy we'll go 340 00:05:58,469 --> 00:05:58,479 so in our object shader destroy we'll go 341 00:05:58,479 --> 00:05:59,990 so in our object shader destroy we'll go ahead and put 342 00:05:59,990 --> 00:06:00,000 ahead and put 343 00:06:00,000 --> 00:06:01,990 ahead and put destroy shader modules 344 00:06:01,990 --> 00:06:02,000 destroy shader modules 345 00:06:02,000 --> 00:06:04,070 destroy shader modules and this should actually be using the 346 00:06:04,070 --> 00:06:04,080 and this should actually be using the 347 00:06:04,080 --> 00:06:05,830 and this should actually be using the context 348 00:06:05,830 --> 00:06:05,840 context 349 00:06:05,840 --> 00:06:07,930 context device 350 00:06:07,930 --> 00:06:07,940 device 351 00:06:07,940 --> 00:06:09,510 device [Music] 352 00:06:09,510 --> 00:06:09,520 [Music] 353 00:06:09,520 --> 00:06:11,390 [Music] logical device 354 00:06:11,390 --> 00:06:11,400 logical device 355 00:06:11,400 --> 00:06:13,110 logical device [Music] 356 00:06:13,110 --> 00:06:13,120 [Music] 357 00:06:13,120 --> 00:06:15,990 [Music] and that will allow us to 358 00:06:15,990 --> 00:06:16,000 and that will allow us to 359 00:06:16,000 --> 00:06:17,749 and that will allow us to not get these validation errors anymore 360 00:06:17,749 --> 00:06:17,759 not get these validation errors anymore 361 00:06:17,759 --> 00:06:19,830 not get these validation errors anymore of course that means that this vulcan 362 00:06:19,830 --> 00:06:19,840 of course that means that this vulcan 363 00:06:19,840 --> 00:06:21,830 of course that means that this vulcan object shader destroy needs to also be 364 00:06:21,830 --> 00:06:21,840 object shader destroy needs to also be 365 00:06:21,840 --> 00:06:24,710 object shader destroy needs to also be called so we'll go into vulcan back end 366 00:06:24,710 --> 00:06:24,720 called so we'll go into vulcan back end 367 00:06:24,720 --> 00:06:26,230 called so we'll go into vulcan back end and in the shutdown 368 00:06:26,230 --> 00:06:26,240 and in the shutdown 369 00:06:26,240 --> 00:06:28,790 and in the shutdown we will put this 370 00:06:28,790 --> 00:06:28,800 we will put this 371 00:06:28,800 --> 00:06:30,790 we will put this since we're doing this last we will put 372 00:06:30,790 --> 00:06:30,800 since we're doing this last we will put 373 00:06:30,800 --> 00:06:34,070 since we're doing this last we will put it first here 374 00:06:34,070 --> 00:06:34,080 it first here 375 00:06:34,080 --> 00:06:36,150 it first here so here we will actually destroy our 376 00:06:36,150 --> 00:06:36,160 so here we will actually destroy our 377 00:06:36,160 --> 00:06:38,629 so here we will actually destroy our object shader and render a back end 378 00:06:38,629 --> 00:06:38,639 object shader and render a back end 379 00:06:38,639 --> 00:06:39,990 object shader and render a back end shutdown 380 00:06:39,990 --> 00:06:40,000 shutdown 381 00:06:40,000 --> 00:06:42,150 shutdown passing of course the context and 382 00:06:42,150 --> 00:06:42,160 passing of course the context and 383 00:06:42,160 --> 00:06:44,790 passing of course the context and a the address of the shader itself so 384 00:06:44,790 --> 00:06:44,800 a the address of the shader itself so 385 00:06:44,800 --> 00:06:47,350 a the address of the shader itself so let's go ahead and build this 386 00:06:47,350 --> 00:06:47,360 let's go ahead and build this 387 00:06:47,360 --> 00:06:50,070 let's go ahead and build this run it 388 00:06:50,070 --> 00:06:50,080 389 00:06:50,080 --> 00:06:51,670 and shut it down 390 00:06:51,670 --> 00:06:51,680 and shut it down 391 00:06:51,680 --> 00:06:53,589 and shut it down and now that validation error is gone 392 00:06:53,589 --> 00:06:53,599 and now that validation error is gone 393 00:06:53,599 --> 00:06:55,189 and now that validation error is gone okay 394 00:06:55,189 --> 00:06:55,199 okay 395 00:06:55,199 --> 00:06:57,589 okay all right so the next thing that we need 396 00:06:57,589 --> 00:06:57,599 all right so the next thing that we need 397 00:06:57,599 --> 00:07:00,629 all right so the next thing that we need to do is we're actually going to 398 00:07:00,629 --> 00:07:00,639 to do is we're actually going to 399 00:07:00,639 --> 00:07:02,070 to do is we're actually going to skip the descriptors for now and we're 400 00:07:02,070 --> 00:07:02,080 skip the descriptors for now and we're 401 00:07:02,080 --> 00:07:04,469 skip the descriptors for now and we're actually going to set up the 402 00:07:04,469 --> 00:07:04,479 actually going to set up the 403 00:07:04,479 --> 00:07:05,830 actually going to set up the pipeline 404 00:07:05,830 --> 00:07:05,840 pipeline 405 00:07:05,840 --> 00:07:07,670 pipeline and we will come back to descriptors and 406 00:07:07,670 --> 00:07:07,680 and we will come back to descriptors and 407 00:07:07,680 --> 00:07:09,670 and we will come back to descriptors and go over what those are but for right now 408 00:07:09,670 --> 00:07:09,680 go over what those are but for right now 409 00:07:09,680 --> 00:07:11,990 go over what those are but for right now um i think it makes more sense to sort 410 00:07:11,990 --> 00:07:12,000 um i think it makes more sense to sort 411 00:07:12,000 --> 00:07:13,909 um i think it makes more sense to sort of create the pipeline 412 00:07:13,909 --> 00:07:13,919 of create the pipeline 413 00:07:13,919 --> 00:07:15,430 of create the pipeline first 414 00:07:15,430 --> 00:07:15,440 first 415 00:07:15,440 --> 00:07:18,710 first so the pipeline as i mentioned before is 416 00:07:18,710 --> 00:07:18,720 so the pipeline as i mentioned before is 417 00:07:18,720 --> 00:07:21,670 so the pipeline as i mentioned before is basically a structure in vulcan that 418 00:07:21,670 --> 00:07:21,680 basically a structure in vulcan that 419 00:07:21,680 --> 00:07:24,390 basically a structure in vulcan that connects a lot of the various pieces of 420 00:07:24,390 --> 00:07:24,400 connects a lot of the various pieces of 421 00:07:24,400 --> 00:07:25,350 connects a lot of the various pieces of a 422 00:07:25,350 --> 00:07:25,360 a 423 00:07:25,360 --> 00:07:27,029 a render pipeline together 424 00:07:27,029 --> 00:07:27,039 render pipeline together 425 00:07:27,039 --> 00:07:30,390 render pipeline together pieces such as descriptions of vertex 426 00:07:30,390 --> 00:07:30,400 pieces such as descriptions of vertex 427 00:07:30,400 --> 00:07:31,909 pieces such as descriptions of vertex information 428 00:07:31,909 --> 00:07:31,919 information 429 00:07:31,919 --> 00:07:35,830 information and lay up the layout of that as well as 430 00:07:35,830 --> 00:07:35,840 and lay up the layout of that as well as 431 00:07:35,840 --> 00:07:37,510 and lay up the layout of that as well as our shader modules that we've created 432 00:07:37,510 --> 00:07:37,520 our shader modules that we've created 433 00:07:37,520 --> 00:07:38,390 our shader modules that we've created here 434 00:07:38,390 --> 00:07:38,400 here 435 00:07:38,400 --> 00:07:40,710 here our render pass that we created in 436 00:07:40,710 --> 00:07:40,720 our render pass that we created in 437 00:07:40,720 --> 00:07:42,150 our render pass that we created in previous videos 438 00:07:42,150 --> 00:07:42,160 previous videos 439 00:07:42,160 --> 00:07:43,830 previous videos things like that so basically this is 440 00:07:43,830 --> 00:07:43,840 things like that so basically this is 441 00:07:43,840 --> 00:07:45,670 things like that so basically this is the glue that holds all that together 442 00:07:45,670 --> 00:07:45,680 the glue that holds all that together 443 00:07:45,680 --> 00:07:48,629 the glue that holds all that together right and then um we can then use those 444 00:07:48,629 --> 00:07:48,639 right and then um we can then use those 445 00:07:48,639 --> 00:07:50,710 right and then um we can then use those pipelines so to speak 446 00:07:50,710 --> 00:07:50,720 pipelines so to speak 447 00:07:50,720 --> 00:07:53,830 pipelines so to speak uh as our actual shader so 448 00:07:53,830 --> 00:07:53,840 uh as our actual shader so 449 00:07:53,840 --> 00:07:56,150 uh as our actual shader so these are generally speaking going to be 450 00:07:56,150 --> 00:07:56,160 these are generally speaking going to be 451 00:07:56,160 --> 00:07:58,710 these are generally speaking going to be unique per shader 452 00:07:58,710 --> 00:07:58,720 unique per shader 453 00:07:58,720 --> 00:08:01,589 unique per shader at least for now until we get into more 454 00:08:01,589 --> 00:08:01,599 at least for now until we get into more 455 00:08:01,599 --> 00:08:02,869 at least for now until we get into more configurable 456 00:08:02,869 --> 00:08:02,879 configurable 457 00:08:02,879 --> 00:08:04,469 configurable pipelines and things of that nature so 458 00:08:04,469 --> 00:08:04,479 pipelines and things of that nature so 459 00:08:04,479 --> 00:08:07,749 pipelines and things of that nature so for now i'm going to create the pipeline 460 00:08:07,749 --> 00:08:07,759 for now i'm going to create the pipeline 461 00:08:07,759 --> 00:08:10,070 for now i'm going to create the pipeline inside of the vulcan 462 00:08:10,070 --> 00:08:10,080 inside of the vulcan 463 00:08:10,080 --> 00:08:11,430 inside of the vulcan object shader 464 00:08:11,430 --> 00:08:11,440 object shader 465 00:08:11,440 --> 00:08:12,950 object shader creation 466 00:08:12,950 --> 00:08:12,960 creation 467 00:08:12,960 --> 00:08:14,950 creation however i am going to do the creation of 468 00:08:14,950 --> 00:08:14,960 however i am going to do the creation of 469 00:08:14,960 --> 00:08:16,629 however i am going to do the creation of this in a separate file it's just going 470 00:08:16,629 --> 00:08:16,639 this in a separate file it's just going 471 00:08:16,639 --> 00:08:18,629 this in a separate file it's just going to be sort of um 472 00:08:18,629 --> 00:08:18,639 to be sort of um 473 00:08:18,639 --> 00:08:19,990 to be sort of um there's going to be one created 474 00:08:19,990 --> 00:08:20,000 there's going to be one created 475 00:08:20,000 --> 00:08:22,230 there's going to be one created specifically for this right and it'll be 476 00:08:22,230 --> 00:08:22,240 specifically for this right and it'll be 477 00:08:22,240 --> 00:08:24,630 specifically for this right and it'll be stored as part of the shader 478 00:08:24,630 --> 00:08:24,640 stored as part of the shader 479 00:08:24,640 --> 00:08:25,749 stored as part of the shader [Music] 480 00:08:25,749 --> 00:08:25,759 [Music] 481 00:08:25,759 --> 00:08:27,909 [Music] i hope that makes sense uh under vulcan 482 00:08:27,909 --> 00:08:27,919 i hope that makes sense uh under vulcan 483 00:08:27,919 --> 00:08:29,909 i hope that makes sense uh under vulcan i'm going to create a new file 484 00:08:29,909 --> 00:08:29,919 i'm going to create a new file 485 00:08:29,919 --> 00:08:32,310 i'm going to create a new file i'm going to call it vulcanpipeline.h 486 00:08:32,310 --> 00:08:32,320 i'm going to call it vulcanpipeline.h 487 00:08:32,320 --> 00:08:34,790 i'm going to call it vulcanpipeline.h obviously we will want uh pragma once 488 00:08:34,790 --> 00:08:34,800 obviously we will want uh pragma once 489 00:08:34,800 --> 00:08:36,510 obviously we will want uh pragma once and vulcan types inl 490 00:08:36,510 --> 00:08:36,520 and vulcan types inl 491 00:08:36,520 --> 00:08:37,750 and vulcan types inl [Music] 492 00:08:37,750 --> 00:08:37,760 [Music] 493 00:08:37,760 --> 00:08:40,870 [Music] and we are going to have a 494 00:08:40,870 --> 00:08:40,880 and we are going to have a 495 00:08:40,880 --> 00:08:44,310 and we are going to have a create for our graphics pipeline 496 00:08:44,310 --> 00:08:44,320 create for our graphics pipeline 497 00:08:44,320 --> 00:08:45,590 create for our graphics pipeline and this is going to take a whole bunch 498 00:08:45,590 --> 00:08:45,600 and this is going to take a whole bunch 499 00:08:45,600 --> 00:08:46,870 and this is going to take a whole bunch of parameters which i'm not going to 500 00:08:46,870 --> 00:08:46,880 of parameters which i'm not going to 501 00:08:46,880 --> 00:08:48,389 of parameters which i'm not going to explain what all of these are right now 502 00:08:48,389 --> 00:08:48,399 explain what all of these are right now 503 00:08:48,399 --> 00:08:49,829 explain what all of these are right now but some of them should at least look 504 00:08:49,829 --> 00:08:49,839 but some of them should at least look 505 00:08:49,839 --> 00:08:51,670 but some of them should at least look familiar to you so obviously we have the 506 00:08:51,670 --> 00:08:51,680 familiar to you so obviously we have the 507 00:08:51,680 --> 00:08:52,790 familiar to you so obviously we have the context 508 00:08:52,790 --> 00:08:52,800 context 509 00:08:52,800 --> 00:08:54,310 context the render pass that's going to be used 510 00:08:54,310 --> 00:08:54,320 the render pass that's going to be used 511 00:08:54,320 --> 00:08:56,310 the render pass that's going to be used with the pipeline 512 00:08:56,310 --> 00:08:56,320 with the pipeline 513 00:08:56,320 --> 00:08:58,310 with the pipeline and i should mention that this render 514 00:08:58,310 --> 00:08:58,320 and i should mention that this render 515 00:08:58,320 --> 00:09:00,389 and i should mention that this render pass is compatible so it doesn't 516 00:09:00,389 --> 00:09:00,399 pass is compatible so it doesn't 517 00:09:00,399 --> 00:09:02,630 pass is compatible so it doesn't necessarily have to use this render pass 518 00:09:02,630 --> 00:09:02,640 necessarily have to use this render pass 519 00:09:02,640 --> 00:09:04,310 necessarily have to use this render pass it just has to use a render pass that 520 00:09:04,310 --> 00:09:04,320 it just has to use a render pass that 521 00:09:04,320 --> 00:09:06,790 it just has to use a render pass that has the same setup as this render pass 522 00:09:06,790 --> 00:09:06,800 has the same setup as this render pass 523 00:09:06,800 --> 00:09:09,750 has the same setup as this render pass so i just want to point that out 524 00:09:09,750 --> 00:09:09,760 so i just want to point that out 525 00:09:09,760 --> 00:09:11,990 so i just want to point that out uh our attribute count as well as our 526 00:09:11,990 --> 00:09:12,000 uh our attribute count as well as our 527 00:09:12,000 --> 00:09:13,670 uh our attribute count as well as our attributes i'll get into what attributes 528 00:09:13,670 --> 00:09:13,680 attributes i'll get into what attributes 529 00:09:13,680 --> 00:09:15,670 attributes i'll get into what attributes are in a bit our descriptor set layout 530 00:09:15,670 --> 00:09:15,680 are in a bit our descriptor set layout 531 00:09:15,680 --> 00:09:17,350 are in a bit our descriptor set layout count as well as our descriptor set 532 00:09:17,350 --> 00:09:17,360 count as well as our descriptor set 533 00:09:17,360 --> 00:09:19,030 count as well as our descriptor set layouts again i'll get into that in a 534 00:09:19,030 --> 00:09:19,040 layouts again i'll get into that in a 535 00:09:19,040 --> 00:09:20,310 layouts again i'll get into that in a minute 536 00:09:20,310 --> 00:09:20,320 minute 537 00:09:20,320 --> 00:09:22,949 minute the number of stages we have the stage 538 00:09:22,949 --> 00:09:22,959 the number of stages we have the stage 539 00:09:22,959 --> 00:09:24,710 the number of stages we have the stage create infos that are associated with 540 00:09:24,710 --> 00:09:24,720 create infos that are associated with 541 00:09:24,720 --> 00:09:26,310 create infos that are associated with that 542 00:09:26,310 --> 00:09:26,320 that 543 00:09:26,320 --> 00:09:28,710 that the viewport the scissor which we have 544 00:09:28,710 --> 00:09:28,720 the viewport the scissor which we have 545 00:09:28,720 --> 00:09:30,310 the viewport the scissor which we have created before 546 00:09:30,310 --> 00:09:30,320 created before 547 00:09:30,320 --> 00:09:32,070 created before whether or not this is actually going to 548 00:09:32,070 --> 00:09:32,080 whether or not this is actually going to 549 00:09:32,080 --> 00:09:34,550 whether or not this is actually going to be a wireframe pipeline because that is 550 00:09:34,550 --> 00:09:34,560 be a wireframe pipeline because that is 551 00:09:34,560 --> 00:09:37,430 be a wireframe pipeline because that is the kind of thing configuration that we 552 00:09:37,430 --> 00:09:37,440 the kind of thing configuration that we 553 00:09:37,440 --> 00:09:39,590 the kind of thing configuration that we need to actually declare here 554 00:09:39,590 --> 00:09:39,600 need to actually declare here 555 00:09:39,600 --> 00:09:42,550 need to actually declare here as well as a pointer to the vulcan 556 00:09:42,550 --> 00:09:42,560 as well as a pointer to the vulcan 557 00:09:42,560 --> 00:09:45,030 as well as a pointer to the vulcan pipeline structure that will actually 558 00:09:45,030 --> 00:09:45,040 pipeline structure that will actually 559 00:09:45,040 --> 00:09:47,030 pipeline structure that will actually contain the created pipeline when we're 560 00:09:47,030 --> 00:09:47,040 contain the created pipeline when we're 561 00:09:47,040 --> 00:09:48,070 contain the created pipeline when we're done 562 00:09:48,070 --> 00:09:48,080 done 563 00:09:48,080 --> 00:09:49,030 done so 564 00:09:49,030 --> 00:09:49,040 so 565 00:09:49,040 --> 00:09:51,670 so this may wind up actually changing into 566 00:09:51,670 --> 00:09:51,680 this may wind up actually changing into 567 00:09:51,680 --> 00:09:53,430 this may wind up actually changing into a structure instead of passing so many 568 00:09:53,430 --> 00:09:53,440 a structure instead of passing so many 569 00:09:53,440 --> 00:09:55,269 a structure instead of passing so many parameters i may wind up creating a 570 00:09:55,269 --> 00:09:55,279 parameters i may wind up creating a 571 00:09:55,279 --> 00:09:56,389 parameters i may wind up creating a structure 572 00:09:56,389 --> 00:09:56,399 structure 573 00:09:56,399 --> 00:09:58,150 structure for this um 574 00:09:58,150 --> 00:09:58,160 for this um 575 00:09:58,160 --> 00:10:00,150 for this um to simplify this interface a little bit 576 00:10:00,150 --> 00:10:00,160 to simplify this interface a little bit 577 00:10:00,160 --> 00:10:02,470 to simplify this interface a little bit but for right now um 578 00:10:02,470 --> 00:10:02,480 but for right now um 579 00:10:02,480 --> 00:10:04,470 but for right now um it's a little bit simpler in code 580 00:10:04,470 --> 00:10:04,480 it's a little bit simpler in code 581 00:10:04,480 --> 00:10:05,590 it's a little bit simpler in code to just have 582 00:10:05,590 --> 00:10:05,600 to just have 583 00:10:05,600 --> 00:10:07,590 to just have this many 584 00:10:07,590 --> 00:10:07,600 this many 585 00:10:07,600 --> 00:10:09,350 this many parameters just because it's probably 586 00:10:09,350 --> 00:10:09,360 parameters just because it's probably 587 00:10:09,360 --> 00:10:10,770 parameters just because it's probably going to be changing 588 00:10:10,770 --> 00:10:10,780 going to be changing 589 00:10:10,780 --> 00:10:12,230 going to be changing [Music] 590 00:10:12,230 --> 00:10:12,240 [Music] 591 00:10:12,240 --> 00:10:14,230 [Music] pipeline destroy is much simpler just 592 00:10:14,230 --> 00:10:14,240 pipeline destroy is much simpler just 593 00:10:14,240 --> 00:10:15,829 pipeline destroy is much simpler just takes the context and the pipeline in 594 00:10:15,829 --> 00:10:15,839 takes the context and the pipeline in 595 00:10:15,839 --> 00:10:17,990 takes the context and the pipeline in fact i'm going to keep that on one line 596 00:10:17,990 --> 00:10:18,000 fact i'm going to keep that on one line 597 00:10:18,000 --> 00:10:18,949 fact i'm going to keep that on one line and then 598 00:10:18,949 --> 00:10:18,959 and then 599 00:10:18,959 --> 00:10:21,110 and then the only other thing that we have is 600 00:10:21,110 --> 00:10:21,120 the only other thing that we have is 601 00:10:21,120 --> 00:10:22,150 the only other thing that we have is just a 602 00:10:22,150 --> 00:10:22,160 just a 603 00:10:22,160 --> 00:10:23,590 just a simple call to 604 00:10:23,590 --> 00:10:23,600 simple call to 605 00:10:23,600 --> 00:10:25,590 simple call to pipeline bind because we actually need 606 00:10:25,590 --> 00:10:25,600 pipeline bind because we actually need 607 00:10:25,600 --> 00:10:27,590 pipeline bind because we actually need to bind a pipeline in order to be able 608 00:10:27,590 --> 00:10:27,600 to bind a pipeline in order to be able 609 00:10:27,600 --> 00:10:28,710 to bind a pipeline in order to be able to use it 610 00:10:28,710 --> 00:10:28,720 to use it 611 00:10:28,720 --> 00:10:30,870 to use it it's 612 00:10:30,870 --> 00:10:30,880 it's 613 00:10:30,880 --> 00:10:33,430 it's those terms can basically be uh 614 00:10:33,430 --> 00:10:33,440 those terms can basically be uh 615 00:10:33,440 --> 00:10:34,949 those terms can basically be uh interchanged 616 00:10:34,949 --> 00:10:34,959 interchanged 617 00:10:34,959 --> 00:10:36,949 interchanged at this point uh basically whenever you 618 00:10:36,949 --> 00:10:36,959 at this point uh basically whenever you 619 00:10:36,959 --> 00:10:39,110 at this point uh basically whenever you bind a pipeline you're saying any any 620 00:10:39,110 --> 00:10:39,120 bind a pipeline you're saying any any 621 00:10:39,120 --> 00:10:40,630 bind a pipeline you're saying any any commands that occur in the command 622 00:10:40,630 --> 00:10:40,640 commands that occur in the command 623 00:10:40,640 --> 00:10:41,750 commands that occur in the command buffer 624 00:10:41,750 --> 00:10:41,760 buffer 625 00:10:41,760 --> 00:10:43,750 buffer while this pipeline is bound will be 626 00:10:43,750 --> 00:10:43,760 while this pipeline is bound will be 627 00:10:43,760 --> 00:10:46,470 while this pipeline is bound will be executed against that pipeline okay so 628 00:10:46,470 --> 00:10:46,480 executed against that pipeline okay so 629 00:10:46,480 --> 00:10:48,470 executed against that pipeline okay so obviously that's going to take a command 630 00:10:48,470 --> 00:10:48,480 obviously that's going to take a command 631 00:10:48,480 --> 00:10:49,430 obviously that's going to take a command buffer 632 00:10:49,430 --> 00:10:49,440 buffer 633 00:10:49,440 --> 00:10:50,949 buffer uh the pipeline bind point which i'll 634 00:10:50,949 --> 00:10:50,959 uh the pipeline bind point which i'll 635 00:10:50,959 --> 00:10:52,150 uh the pipeline bind point which i'll get to in a bit 636 00:10:52,150 --> 00:10:52,160 get to in a bit 637 00:10:52,160 --> 00:10:54,790 get to in a bit and then uh obviously a pointer to the 638 00:10:54,790 --> 00:10:54,800 and then uh obviously a pointer to the 639 00:10:54,800 --> 00:10:57,350 and then uh obviously a pointer to the pipeline itself okay 640 00:10:57,350 --> 00:10:57,360 pipeline itself okay 641 00:10:57,360 --> 00:10:59,350 pipeline itself okay and that is our interface it's actually 642 00:10:59,350 --> 00:10:59,360 and that is our interface it's actually 643 00:10:59,360 --> 00:11:01,590 and that is our interface it's actually pretty pretty straightforward and it's 644 00:11:01,590 --> 00:11:01,600 pretty pretty straightforward and it's 645 00:11:01,600 --> 00:11:03,910 pretty pretty straightforward and it's not too big okay so now i'm going to 646 00:11:03,910 --> 00:11:03,920 not too big okay so now i'm going to 647 00:11:03,920 --> 00:11:05,509 not too big okay so now i'm going to copy 648 00:11:05,509 --> 00:11:05,519 copy 649 00:11:05,519 --> 00:11:07,829 copy these signatures and i'm going to go to 650 00:11:07,829 --> 00:11:07,839 these signatures and i'm going to go to 651 00:11:07,839 --> 00:11:09,829 these signatures and i'm going to go to here and create a new file 652 00:11:09,829 --> 00:11:09,839 here and create a new file 653 00:11:09,839 --> 00:11:13,350 here and create a new file called vulcanpipeline.c 654 00:11:13,350 --> 00:11:13,360 655 00:11:13,360 --> 00:11:16,150 and i'm going to paste these guys in 656 00:11:16,150 --> 00:11:16,160 and i'm going to paste these guys in 657 00:11:16,160 --> 00:11:18,540 and i'm going to paste these guys in convert them to a function definition 658 00:11:18,540 --> 00:11:18,550 convert them to a function definition 659 00:11:18,550 --> 00:11:21,030 convert them to a function definition [Music] 660 00:11:21,030 --> 00:11:21,040 [Music] 661 00:11:21,040 --> 00:11:26,230 [Music] and then 662 00:11:26,230 --> 00:11:26,240 663 00:11:26,240 --> 00:11:27,829 i'll go ahead and include vulcan 664 00:11:27,829 --> 00:11:27,839 i'll go ahead and include vulcan 665 00:11:27,839 --> 00:11:29,350 i'll go ahead and include vulcan pipeline dot h 666 00:11:29,350 --> 00:11:29,360 pipeline dot h 667 00:11:29,360 --> 00:11:32,069 pipeline dot h okay 668 00:11:32,069 --> 00:11:32,079 669 00:11:32,079 --> 00:11:34,150 we're also going to need 670 00:11:34,150 --> 00:11:34,160 we're also going to need 671 00:11:34,160 --> 00:11:36,949 we're also going to need vulcanutils.h 672 00:11:36,949 --> 00:11:36,959 vulcanutils.h 673 00:11:36,959 --> 00:11:39,829 vulcanutils.h okay and we're going to need the core 674 00:11:39,829 --> 00:11:39,839 okay and we're going to need the core 675 00:11:39,839 --> 00:11:42,790 okay and we're going to need the core k memory and the logger for this 676 00:11:42,790 --> 00:11:42,800 k memory and the logger for this 677 00:11:42,800 --> 00:11:44,470 k memory and the logger for this okay 678 00:11:44,470 --> 00:11:44,480 okay 679 00:11:44,480 --> 00:11:46,230 okay so our 680 00:11:46,230 --> 00:11:46,240 so our 681 00:11:46,240 --> 00:11:48,550 so our vulcan graphics pipeline creates is 682 00:11:48,550 --> 00:11:48,560 vulcan graphics pipeline creates is 683 00:11:48,560 --> 00:11:50,310 vulcan graphics pipeline creates is basically going to return true if 684 00:11:50,310 --> 00:11:50,320 basically going to return true if 685 00:11:50,320 --> 00:11:52,470 basically going to return true if successful otherwise false 686 00:11:52,470 --> 00:11:52,480 successful otherwise false 687 00:11:52,480 --> 00:11:54,389 successful otherwise false and thankfully there's not a whole heck 688 00:11:54,389 --> 00:11:54,399 and thankfully there's not a whole heck 689 00:11:54,399 --> 00:11:57,269 and thankfully there's not a whole heck of a lot to it so 690 00:11:57,269 --> 00:11:57,279 of a lot to it so 691 00:11:57,279 --> 00:11:58,790 of a lot to it so the first thing that we have to create 692 00:11:58,790 --> 00:11:58,800 the first thing that we have to create 693 00:11:58,800 --> 00:12:01,590 the first thing that we have to create is something called the viewport state 694 00:12:01,590 --> 00:12:01,600 is something called the viewport state 695 00:12:01,600 --> 00:12:05,350 is something called the viewport state and this is basically going to take our 696 00:12:05,350 --> 00:12:05,360 and this is basically going to take our 697 00:12:05,360 --> 00:12:07,350 and this is basically going to take our past in viewport and scissor again we're 698 00:12:07,350 --> 00:12:07,360 past in viewport and scissor again we're 699 00:12:07,360 --> 00:12:08,710 past in viewport and scissor again we're making the assumption here that there's 700 00:12:08,710 --> 00:12:08,720 making the assumption here that there's 701 00:12:08,720 --> 00:12:10,710 making the assumption here that there's only one of each this may be something 702 00:12:10,710 --> 00:12:10,720 only one of each this may be something 703 00:12:10,720 --> 00:12:13,430 only one of each this may be something that we have to change in the future 704 00:12:13,430 --> 00:12:13,440 that we have to change in the future 705 00:12:13,440 --> 00:12:14,790 that we have to change in the future but for right now this is basically 706 00:12:14,790 --> 00:12:14,800 but for right now this is basically 707 00:12:14,800 --> 00:12:16,389 but for right now this is basically saying this is the initial viewport and 708 00:12:16,389 --> 00:12:16,399 saying this is the initial viewport and 709 00:12:16,399 --> 00:12:17,829 saying this is the initial viewport and scissor that we want to use with this 710 00:12:17,829 --> 00:12:17,839 scissor that we want to use with this 711 00:12:17,839 --> 00:12:19,190 scissor that we want to use with this pipeline 712 00:12:19,190 --> 00:12:19,200 pipeline 713 00:12:19,200 --> 00:12:20,550 pipeline and that could be changed by something 714 00:12:20,550 --> 00:12:20,560 and that could be changed by something 715 00:12:20,560 --> 00:12:22,550 and that could be changed by something called dynamic state which i'll get to 716 00:12:22,550 --> 00:12:22,560 called dynamic state which i'll get to 717 00:12:22,560 --> 00:12:25,350 called dynamic state which i'll get to in a moment 718 00:12:25,350 --> 00:12:25,360 in a moment 719 00:12:25,360 --> 00:12:29,030 in a moment next we have the 720 00:12:29,030 --> 00:12:29,040 next we have the 721 00:12:29,040 --> 00:12:31,829 next we have the something called the rasterization state 722 00:12:31,829 --> 00:12:31,839 something called the rasterization state 723 00:12:31,839 --> 00:12:34,949 something called the rasterization state that we need a create info for 724 00:12:34,949 --> 00:12:34,959 that we need a create info for 725 00:12:34,959 --> 00:12:36,949 that we need a create info for so here we have a vk pipeline 726 00:12:36,949 --> 00:12:36,959 so here we have a vk pipeline 727 00:12:36,959 --> 00:12:39,750 so here we have a vk pipeline rasterization state crate info 728 00:12:39,750 --> 00:12:39,760 rasterization state crate info 729 00:12:39,760 --> 00:12:41,430 rasterization state crate info that's a mouthful 730 00:12:41,430 --> 00:12:41,440 that's a mouthful 731 00:12:41,440 --> 00:12:43,509 that's a mouthful and basically we have a whole bunch of 732 00:12:43,509 --> 00:12:43,519 and basically we have a whole bunch of 733 00:12:43,519 --> 00:12:45,190 and basically we have a whole bunch of properties in here 734 00:12:45,190 --> 00:12:45,200 properties in here 735 00:12:45,200 --> 00:12:46,470 properties in here and i'm only going to take time to 736 00:12:46,470 --> 00:12:46,480 and i'm only going to take time to 737 00:12:46,480 --> 00:12:47,990 and i'm only going to take time to actually point out the most common ones 738 00:12:47,990 --> 00:12:48,000 actually point out the most common ones 739 00:12:48,000 --> 00:12:49,829 actually point out the most common ones because or the most important ones for 740 00:12:49,829 --> 00:12:49,839 because or the most important ones for 741 00:12:49,839 --> 00:12:51,670 because or the most important ones for right now because 742 00:12:51,670 --> 00:12:51,680 right now because 743 00:12:51,680 --> 00:12:54,710 right now because most of these won't matter right away 744 00:12:54,710 --> 00:12:54,720 most of these won't matter right away 745 00:12:54,720 --> 00:12:55,430 most of these won't matter right away so 746 00:12:55,430 --> 00:12:55,440 so 747 00:12:55,440 --> 00:12:58,389 so first off this polygon mode right here 748 00:12:58,389 --> 00:12:58,399 first off this polygon mode right here 749 00:12:58,399 --> 00:12:59,990 first off this polygon mode right here is either going to be 750 00:12:59,990 --> 00:13:00,000 is either going to be 751 00:13:00,000 --> 00:13:00,870 is either going to be line 752 00:13:00,870 --> 00:13:00,880 line 753 00:13:00,880 --> 00:13:03,110 line or fill depending on whether or not we 754 00:13:03,110 --> 00:13:03,120 or fill depending on whether or not we 755 00:13:03,120 --> 00:13:04,470 or fill depending on whether or not we say wireframe 756 00:13:04,470 --> 00:13:04,480 say wireframe 757 00:13:04,480 --> 00:13:07,269 say wireframe so that is the reason that we 758 00:13:07,269 --> 00:13:07,279 so that is the reason that we 759 00:13:07,279 --> 00:13:09,350 so that is the reason that we take this boolean right here to say if 760 00:13:09,350 --> 00:13:09,360 take this boolean right here to say if 761 00:13:09,360 --> 00:13:11,829 take this boolean right here to say if we should create this as a wireframe 762 00:13:11,829 --> 00:13:11,839 we should create this as a wireframe 763 00:13:11,839 --> 00:13:13,910 we should create this as a wireframe pipeline uh then we're going to use 764 00:13:13,910 --> 00:13:13,920 pipeline uh then we're going to use 765 00:13:13,920 --> 00:13:15,990 pipeline uh then we're going to use we're going to render the polygons as 766 00:13:15,990 --> 00:13:16,000 we're going to render the polygons as 767 00:13:16,000 --> 00:13:17,670 we're going to render the polygons as lines otherwise we're going to fill them 768 00:13:17,670 --> 00:13:17,680 lines otherwise we're going to fill them 769 00:13:17,680 --> 00:13:18,790 lines otherwise we're going to fill them in 770 00:13:18,790 --> 00:13:18,800 in 771 00:13:18,800 --> 00:13:20,230 in and the reason that you might want to do 772 00:13:20,230 --> 00:13:20,240 and the reason that you might want to do 773 00:13:20,240 --> 00:13:22,150 and the reason that you might want to do this is because 774 00:13:22,150 --> 00:13:22,160 this is because 775 00:13:22,160 --> 00:13:23,910 this is because you are going to have situations where 776 00:13:23,910 --> 00:13:23,920 you are going to have situations where 777 00:13:23,920 --> 00:13:25,990 you are going to have situations where you're going to want a wireframe view of 778 00:13:25,990 --> 00:13:26,000 you're going to want a wireframe view of 779 00:13:26,000 --> 00:13:27,990 you're going to want a wireframe view of your geometry and this is how you would 780 00:13:27,990 --> 00:13:28,000 your geometry and this is how you would 781 00:13:28,000 --> 00:13:29,829 your geometry and this is how you would do that and 782 00:13:29,829 --> 00:13:29,839 do that and 783 00:13:29,839 --> 00:13:31,430 do that and i should note that 784 00:13:31,430 --> 00:13:31,440 i should note that 785 00:13:31,440 --> 00:13:32,949 i should note that since 786 00:13:32,949 --> 00:13:32,959 since 787 00:13:32,959 --> 00:13:34,949 since pipelines are immutable once they're 788 00:13:34,949 --> 00:13:34,959 pipelines are immutable once they're 789 00:13:34,959 --> 00:13:35,910 pipelines are immutable once they're created 790 00:13:35,910 --> 00:13:35,920 created 791 00:13:35,920 --> 00:13:37,750 created it's not like opengl where you can just 792 00:13:37,750 --> 00:13:37,760 it's not like opengl where you can just 793 00:13:37,760 --> 00:13:39,670 it's not like opengl where you can just flip back and forth in terms of what 794 00:13:39,670 --> 00:13:39,680 flip back and forth in terms of what 795 00:13:39,680 --> 00:13:41,990 flip back and forth in terms of what this polygon mode would be once it's set 796 00:13:41,990 --> 00:13:42,000 this polygon mode would be once it's set 797 00:13:42,000 --> 00:13:44,550 this polygon mode would be once it's set it's set so if you want a wireframe 798 00:13:44,550 --> 00:13:44,560 it's set so if you want a wireframe 799 00:13:44,560 --> 00:13:46,069 it's set so if you want a wireframe pipeline you actually have to create a 800 00:13:46,069 --> 00:13:46,079 pipeline you actually have to create a 801 00:13:46,079 --> 00:13:48,230 pipeline you actually have to create a separate pipeline for that and use it 802 00:13:48,230 --> 00:13:48,240 separate pipeline for that and use it 803 00:13:48,240 --> 00:13:49,189 separate pipeline for that and use it instead 804 00:13:49,189 --> 00:13:49,199 instead 805 00:13:49,199 --> 00:13:52,310 instead so that is the reason for this 806 00:13:52,310 --> 00:13:52,320 so that is the reason for this 807 00:13:52,320 --> 00:13:55,590 so that is the reason for this the line width i'm just setting to 1.0 808 00:13:55,590 --> 00:13:55,600 the line width i'm just setting to 1.0 809 00:13:55,600 --> 00:13:58,150 the line width i'm just setting to 1.0 the co mode is just saying we want to 810 00:13:58,150 --> 00:13:58,160 the co mode is just saying we want to 811 00:13:58,160 --> 00:14:00,150 the co mode is just saying we want to call back faces 812 00:14:00,150 --> 00:14:00,160 call back faces 813 00:14:00,160 --> 00:14:02,470 call back faces the front face is basically 814 00:14:02,470 --> 00:14:02,480 the front face is basically 815 00:14:02,480 --> 00:14:04,310 the front face is basically indicating our winding order of our 816 00:14:04,310 --> 00:14:04,320 indicating our winding order of our 817 00:14:04,320 --> 00:14:06,069 indicating our winding order of our geometry 818 00:14:06,069 --> 00:14:06,079 geometry 819 00:14:06,079 --> 00:14:07,269 geometry so 820 00:14:07,269 --> 00:14:07,279 so 821 00:14:07,279 --> 00:14:09,829 so front faces versus back faces are 822 00:14:09,829 --> 00:14:09,839 front faces versus back faces are 823 00:14:09,839 --> 00:14:12,069 front faces versus back faces are determined by the order of the vertices 824 00:14:12,069 --> 00:14:12,079 determined by the order of the vertices 825 00:14:12,079 --> 00:14:14,150 determined by the order of the vertices themselves and whether they go any 826 00:14:14,150 --> 00:14:14,160 themselves and whether they go any 827 00:14:14,160 --> 00:14:16,710 themselves and whether they go any clockwise or counterclockwise 828 00:14:16,710 --> 00:14:16,720 clockwise or counterclockwise 829 00:14:16,720 --> 00:14:18,470 clockwise or counterclockwise direction 830 00:14:18,470 --> 00:14:18,480 direction 831 00:14:18,480 --> 00:14:19,350 direction most 832 00:14:19,350 --> 00:14:19,360 most 833 00:14:19,360 --> 00:14:20,629 most applications tend to use 834 00:14:20,629 --> 00:14:20,639 applications tend to use 835 00:14:20,639 --> 00:14:23,350 applications tend to use counterclockwise to to 836 00:14:23,350 --> 00:14:23,360 counterclockwise to to 837 00:14:23,360 --> 00:14:24,870 counterclockwise to to indicate the front face which is what 838 00:14:24,870 --> 00:14:24,880 indicate the front face which is what 839 00:14:24,880 --> 00:14:26,550 indicate the front face which is what we're going to be doing here 840 00:14:26,550 --> 00:14:26,560 we're going to be doing here 841 00:14:26,560 --> 00:14:28,550 we're going to be doing here so if i were to flip this to 842 00:14:28,550 --> 00:14:28,560 so if i were to flip this to 843 00:14:28,560 --> 00:14:30,629 so if i were to flip this to clockwise then it would actually cull 844 00:14:30,629 --> 00:14:30,639 clockwise then it would actually cull 845 00:14:30,639 --> 00:14:32,790 clockwise then it would actually cull the front faces or what appears to be 846 00:14:32,790 --> 00:14:32,800 the front faces or what appears to be 847 00:14:32,800 --> 00:14:35,110 the front faces or what appears to be the front faces because 848 00:14:35,110 --> 00:14:35,120 the front faces because 849 00:14:35,120 --> 00:14:37,829 the front faces because the winding order is reversed so 850 00:14:37,829 --> 00:14:37,839 the winding order is reversed so 851 00:14:37,839 --> 00:14:40,470 the winding order is reversed so if you guys ever run into issues with 852 00:14:40,470 --> 00:14:40,480 if you guys ever run into issues with 853 00:14:40,480 --> 00:14:42,550 if you guys ever run into issues with your geometry sort of rendering inside 854 00:14:42,550 --> 00:14:42,560 your geometry sort of rendering inside 855 00:14:42,560 --> 00:14:45,430 your geometry sort of rendering inside out or backwards it may have to do with 856 00:14:45,430 --> 00:14:45,440 out or backwards it may have to do with 857 00:14:45,440 --> 00:14:46,790 out or backwards it may have to do with this right 858 00:14:46,790 --> 00:14:46,800 this right 859 00:14:46,800 --> 00:14:47,670 this right also 860 00:14:47,670 --> 00:14:47,680 also 861 00:14:47,680 --> 00:14:50,069 also we could if we wanted to disable 862 00:14:50,069 --> 00:14:50,079 we could if we wanted to disable 863 00:14:50,079 --> 00:14:52,629 we could if we wanted to disable backface culling we could set this to 864 00:14:52,629 --> 00:14:52,639 backface culling we could set this to 865 00:14:52,639 --> 00:14:54,629 backface culling we could set this to disable that but for right now we 866 00:14:54,629 --> 00:14:54,639 disable that but for right now we 867 00:14:54,639 --> 00:14:55,829 disable that but for right now we actually want to 868 00:14:55,829 --> 00:14:55,839 actually want to 869 00:14:55,839 --> 00:14:57,910 actually want to disable back faces which means we don't 870 00:14:57,910 --> 00:14:57,920 disable back faces which means we don't 871 00:14:57,920 --> 00:15:00,230 disable back faces which means we don't want to see the back side of of geometry 872 00:15:00,230 --> 00:15:00,240 want to see the back side of of geometry 873 00:15:00,240 --> 00:15:02,150 want to see the back side of of geometry we don't want to render that as far as 874 00:15:02,150 --> 00:15:02,160 we don't want to render that as far as 875 00:15:02,160 --> 00:15:03,590 we don't want to render that as far as the rest of this stuff it's not really 876 00:15:03,590 --> 00:15:03,600 the rest of this stuff it's not really 877 00:15:03,600 --> 00:15:05,189 the rest of this stuff it's not really important for the time being i just set 878 00:15:05,189 --> 00:15:05,199 important for the time being i just set 879 00:15:05,199 --> 00:15:06,870 important for the time being i just set it explicitly here 880 00:15:06,870 --> 00:15:06,880 it explicitly here 881 00:15:06,880 --> 00:15:08,310 it explicitly here just so that we can come in and change 882 00:15:08,310 --> 00:15:08,320 just so that we can come in and change 883 00:15:08,320 --> 00:15:10,470 just so that we can come in and change it later on so 884 00:15:10,470 --> 00:15:10,480 it later on so 885 00:15:10,480 --> 00:15:12,470 it later on so i am going to move on the next thing 886 00:15:12,470 --> 00:15:12,480 i am going to move on the next thing 887 00:15:12,480 --> 00:15:14,230 i am going to move on the next thing that we need to configure is 888 00:15:14,230 --> 00:15:14,240 that we need to configure is 889 00:15:14,240 --> 00:15:16,230 that we need to configure is multi-sampling multi-sampling is not 890 00:15:16,230 --> 00:15:16,240 multi-sampling multi-sampling is not 891 00:15:16,240 --> 00:15:17,189 multi-sampling multi-sampling is not something that we're going to be using 892 00:15:17,189 --> 00:15:17,199 something that we're going to be using 893 00:15:17,199 --> 00:15:18,790 something that we're going to be using right off the bat so i've set some 894 00:15:18,790 --> 00:15:18,800 right off the bat so i've set some 895 00:15:18,800 --> 00:15:20,710 right off the bat so i've set some defaults here to say we're just going to 896 00:15:20,710 --> 00:15:20,720 defaults here to say we're just going to 897 00:15:20,720 --> 00:15:22,870 defaults here to say we're just going to use a single sample 898 00:15:22,870 --> 00:15:22,880 use a single sample 899 00:15:22,880 --> 00:15:25,350 use a single sample and that is basically it 900 00:15:25,350 --> 00:15:25,360 and that is basically it 901 00:15:25,360 --> 00:15:26,790 and that is basically it multi-sampling is something we'll 902 00:15:26,790 --> 00:15:26,800 multi-sampling is something we'll 903 00:15:26,800 --> 00:15:29,509 multi-sampling is something we'll probably come back to but for now it's 904 00:15:29,509 --> 00:15:29,519 probably come back to but for now it's 905 00:15:29,519 --> 00:15:32,470 probably come back to but for now it's not something i'm going to implement 906 00:15:32,470 --> 00:15:32,480 not something i'm going to implement 907 00:15:32,480 --> 00:15:34,069 not something i'm going to implement depth and stencil testing is another 908 00:15:34,069 --> 00:15:34,079 depth and stencil testing is another 909 00:15:34,079 --> 00:15:36,470 depth and stencil testing is another thing so we are actually going to 910 00:15:36,470 --> 00:15:36,480 thing so we are actually going to 911 00:15:36,480 --> 00:15:38,470 thing so we are actually going to enable depth testing 912 00:15:38,470 --> 00:15:38,480 enable depth testing 913 00:15:38,480 --> 00:15:40,550 enable depth testing and enable we're also going to enable 914 00:15:40,550 --> 00:15:40,560 and enable we're also going to enable 915 00:15:40,560 --> 00:15:42,629 and enable we're also going to enable writing to the depth buffer 916 00:15:42,629 --> 00:15:42,639 writing to the depth buffer 917 00:15:42,639 --> 00:15:45,749 writing to the depth buffer and then uh this is our depth compare up 918 00:15:45,749 --> 00:15:45,759 and then uh this is our depth compare up 919 00:15:45,759 --> 00:15:47,590 and then uh this is our depth compare up so basically this is saying 920 00:15:47,590 --> 00:15:47,600 so basically this is saying 921 00:15:47,600 --> 00:15:50,550 so basically this is saying when we compare two different depths um 922 00:15:50,550 --> 00:15:50,560 when we compare two different depths um 923 00:15:50,560 --> 00:15:51,990 when we compare two different depths um what is the comparison that we want to 924 00:15:51,990 --> 00:15:52,000 what is the comparison that we want to 925 00:15:52,000 --> 00:15:54,389 what is the comparison that we want to use do we want to use 926 00:15:54,389 --> 00:15:54,399 use do we want to use 927 00:15:54,399 --> 00:15:55,829 use do we want to use less than 928 00:15:55,829 --> 00:15:55,839 less than 929 00:15:55,839 --> 00:15:58,310 less than or greater than or equal there's a bunch 930 00:15:58,310 --> 00:15:58,320 or greater than or equal there's a bunch 931 00:15:58,320 --> 00:16:00,230 or greater than or equal there's a bunch of different operations on this it's 932 00:16:00,230 --> 00:16:00,240 of different operations on this it's 933 00:16:00,240 --> 00:16:03,350 of different operations on this it's basically determining what gets clipped 934 00:16:03,350 --> 00:16:03,360 basically determining what gets clipped 935 00:16:03,360 --> 00:16:06,310 basically determining what gets clipped when you're doing depth testing 936 00:16:06,310 --> 00:16:06,320 when you're doing depth testing 937 00:16:06,320 --> 00:16:09,670 when you're doing depth testing okay and uh we are not using uh stencil 938 00:16:09,670 --> 00:16:09,680 okay and uh we are not using uh stencil 939 00:16:09,680 --> 00:16:11,189 okay and uh we are not using uh stencil testing right now so i've gone ahead and 940 00:16:11,189 --> 00:16:11,199 testing right now so i've gone ahead and 941 00:16:11,199 --> 00:16:13,350 testing right now so i've gone ahead and set that to false 942 00:16:13,350 --> 00:16:13,360 set that to false 943 00:16:13,360 --> 00:16:15,829 set that to false so the next thing is something called 944 00:16:15,829 --> 00:16:15,839 so the next thing is something called 945 00:16:15,839 --> 00:16:18,230 so the next thing is something called color blend attachment state and this 946 00:16:18,230 --> 00:16:18,240 color blend attachment state and this 947 00:16:18,240 --> 00:16:19,910 color blend attachment state and this has to do with 948 00:16:19,910 --> 00:16:19,920 has to do with 949 00:16:19,920 --> 00:16:22,550 has to do with the way that colors are actually written 950 00:16:22,550 --> 00:16:22,560 the way that colors are actually written 951 00:16:22,560 --> 00:16:24,949 the way that colors are actually written to 952 00:16:24,949 --> 00:16:24,959 953 00:16:24,959 --> 00:16:27,110 written to the image right 954 00:16:27,110 --> 00:16:27,120 written to the image right 955 00:16:27,120 --> 00:16:28,629 written to the image right and so 956 00:16:28,629 --> 00:16:28,639 and so 957 00:16:28,639 --> 00:16:30,949 and so these are the various 958 00:16:30,949 --> 00:16:30,959 these are the various 959 00:16:30,959 --> 00:16:32,310 these are the various blending modes 960 00:16:32,310 --> 00:16:32,320 blending modes 961 00:16:32,320 --> 00:16:34,629 blending modes to handle alpha and we'll come back to 962 00:16:34,629 --> 00:16:34,639 to handle alpha and we'll come back to 963 00:16:34,639 --> 00:16:35,990 to handle alpha and we'll come back to these when we actually start handling 964 00:16:35,990 --> 00:16:36,000 these when we actually start handling 965 00:16:36,000 --> 00:16:37,990 these when we actually start handling alpha transparency 966 00:16:37,990 --> 00:16:38,000 alpha transparency 967 00:16:38,000 --> 00:16:40,069 alpha transparency but these this setup will actually allow 968 00:16:40,069 --> 00:16:40,079 but these this setup will actually allow 969 00:16:40,079 --> 00:16:41,829 but these this setup will actually allow us to use alpha transparency when we get 970 00:16:41,829 --> 00:16:41,839 us to use alpha transparency when we get 971 00:16:41,839 --> 00:16:43,430 us to use alpha transparency when we get to that stage so 972 00:16:43,430 --> 00:16:43,440 to that stage so 973 00:16:43,440 --> 00:16:45,189 to that stage so i'll double back at that point and 974 00:16:45,189 --> 00:16:45,199 i'll double back at that point and 975 00:16:45,199 --> 00:16:47,910 i'll double back at that point and describe what all these things are 976 00:16:47,910 --> 00:16:47,920 describe what all these things are 977 00:16:47,920 --> 00:16:50,710 describe what all these things are and also our color right mask indicates 978 00:16:50,710 --> 00:16:50,720 and also our color right mask indicates 979 00:16:50,720 --> 00:16:53,350 and also our color right mask indicates what channels we actually want to write 980 00:16:53,350 --> 00:16:53,360 what channels we actually want to write 981 00:16:53,360 --> 00:16:56,470 what channels we actually want to write and so in this case we want r g b and a 982 00:16:56,470 --> 00:16:56,480 and so in this case we want r g b and a 983 00:16:56,480 --> 00:16:58,389 and so in this case we want r g b and a okay 984 00:16:58,389 --> 00:16:58,399 okay 985 00:16:58,399 --> 00:17:00,949 okay so the next thing is our color blend 986 00:17:00,949 --> 00:17:00,959 so the next thing is our color blend 987 00:17:00,959 --> 00:17:03,670 so the next thing is our color blend state create info so this basically just 988 00:17:03,670 --> 00:17:03,680 state create info so this basically just 989 00:17:03,680 --> 00:17:05,510 state create info so this basically just takes the attachments that we define 990 00:17:05,510 --> 00:17:05,520 takes the attachments that we define 991 00:17:05,520 --> 00:17:06,470 takes the attachments that we define here 992 00:17:06,470 --> 00:17:06,480 here 993 00:17:06,480 --> 00:17:08,390 here again we only have one attachment we're 994 00:17:08,390 --> 00:17:08,400 again we only have one attachment we're 995 00:17:08,400 --> 00:17:10,309 again we only have one attachment we're making that assumption right now 996 00:17:10,309 --> 00:17:10,319 making that assumption right now 997 00:17:10,319 --> 00:17:11,189 making that assumption right now um 998 00:17:11,189 --> 00:17:11,199 um 999 00:17:11,199 --> 00:17:12,789 um we may need to come back and revisit 1000 00:17:12,789 --> 00:17:12,799 we may need to come back and revisit 1001 00:17:12,799 --> 00:17:14,710 we may need to come back and revisit this later but for right now it's okay 1002 00:17:14,710 --> 00:17:14,720 this later but for right now it's okay 1003 00:17:14,720 --> 00:17:17,350 this later but for right now it's okay to make that assumption 1004 00:17:17,350 --> 00:17:17,360 to make that assumption 1005 00:17:17,360 --> 00:17:19,829 to make that assumption uh all right so 1006 00:17:19,829 --> 00:17:19,839 uh all right so 1007 00:17:19,839 --> 00:17:21,110 uh all right so the next thing i want to talk about 1008 00:17:21,110 --> 00:17:21,120 the next thing i want to talk about 1009 00:17:21,120 --> 00:17:24,069 the next thing i want to talk about really quickly is dynamic state so as i 1010 00:17:24,069 --> 00:17:24,079 really quickly is dynamic state so as i 1011 00:17:24,079 --> 00:17:25,750 really quickly is dynamic state so as i mentioned before 1012 00:17:25,750 --> 00:17:25,760 mentioned before 1013 00:17:25,760 --> 00:17:27,669 mentioned before pipelines are immutable 1014 00:17:27,669 --> 00:17:27,679 pipelines are immutable 1015 00:17:27,679 --> 00:17:30,470 pipelines are immutable however there are a few things 1016 00:17:30,470 --> 00:17:30,480 however there are a few things 1017 00:17:30,480 --> 00:17:32,150 however there are a few things within something called dynamic state 1018 00:17:32,150 --> 00:17:32,160 within something called dynamic state 1019 00:17:32,160 --> 00:17:34,470 within something called dynamic state that we can change on the fly 1020 00:17:34,470 --> 00:17:34,480 that we can change on the fly 1021 00:17:34,480 --> 00:17:36,870 that we can change on the fly and viewport and scissor 1022 00:17:36,870 --> 00:17:36,880 and viewport and scissor 1023 00:17:36,880 --> 00:17:39,029 and viewport and scissor as well as actually line width are a few 1024 00:17:39,029 --> 00:17:39,039 as well as actually line width are a few 1025 00:17:39,039 --> 00:17:40,390 as well as actually line width are a few of those things so we can actually 1026 00:17:40,390 --> 00:17:40,400 of those things so we can actually 1027 00:17:40,400 --> 00:17:42,310 of those things so we can actually change these properties 1028 00:17:42,310 --> 00:17:42,320 change these properties 1029 00:17:42,320 --> 00:17:44,950 change these properties by calling various vulcan commands 1030 00:17:44,950 --> 00:17:44,960 by calling various vulcan commands 1031 00:17:44,960 --> 00:17:47,669 by calling various vulcan commands to set those things without having to 1032 00:17:47,669 --> 00:17:47,679 to set those things without having to 1033 00:17:47,679 --> 00:17:51,190 to set those things without having to recreate the pipeline if we wanted to 1034 00:17:51,190 --> 00:17:51,200 recreate the pipeline if we wanted to 1035 00:17:51,200 --> 00:17:52,710 recreate the pipeline if we wanted to change something that is not part of the 1036 00:17:52,710 --> 00:17:52,720 change something that is not part of the 1037 00:17:52,720 --> 00:17:54,549 change something that is not part of the dynamic state we would actually have to 1038 00:17:54,549 --> 00:17:54,559 dynamic state we would actually have to 1039 00:17:54,559 --> 00:17:56,470 dynamic state we would actually have to recreate that pipeline in order to 1040 00:17:56,470 --> 00:17:56,480 recreate that pipeline in order to 1041 00:17:56,480 --> 00:17:58,630 recreate that pipeline in order to actually do that but since 1042 00:17:58,630 --> 00:17:58,640 actually do that but since 1043 00:17:58,640 --> 00:18:00,470 actually do that but since we have this dynamic state 1044 00:18:00,470 --> 00:18:00,480 we have this dynamic state 1045 00:18:00,480 --> 00:18:02,470 we have this dynamic state this is how we're able to actually 1046 00:18:02,470 --> 00:18:02,480 this is how we're able to actually 1047 00:18:02,480 --> 00:18:04,150 this is how we're able to actually resize the window 1048 00:18:04,150 --> 00:18:04,160 resize the window 1049 00:18:04,160 --> 00:18:06,870 resize the window and not have to recreate this whole 1050 00:18:06,870 --> 00:18:06,880 and not have to recreate this whole 1051 00:18:06,880 --> 00:18:09,270 and not have to recreate this whole pipeline every time we do that so 1052 00:18:09,270 --> 00:18:09,280 pipeline every time we do that so 1053 00:18:09,280 --> 00:18:10,630 pipeline every time we do that so dynamic state is actually a pretty 1054 00:18:10,630 --> 00:18:10,640 dynamic state is actually a pretty 1055 00:18:10,640 --> 00:18:12,310 dynamic state is actually a pretty useful thing there are certain things 1056 00:18:12,310 --> 00:18:12,320 useful thing there are certain things 1057 00:18:12,320 --> 00:18:14,549 useful thing there are certain things that you can actually use for that 1058 00:18:14,549 --> 00:18:14,559 that you can actually use for that 1059 00:18:14,559 --> 00:18:16,630 that you can actually use for that and viewport scissor and line with are 1060 00:18:16,630 --> 00:18:16,640 and viewport scissor and line with are 1061 00:18:16,640 --> 00:18:17,750 and viewport scissor and line with are going to be 1062 00:18:17,750 --> 00:18:17,760 going to be 1063 00:18:17,760 --> 00:18:19,029 going to be the three things that we're going to use 1064 00:18:19,029 --> 00:18:19,039 the three things that we're going to use 1065 00:18:19,039 --> 00:18:20,230 the three things that we're going to use right off the bat for that there are 1066 00:18:20,230 --> 00:18:20,240 right off the bat for that there are 1067 00:18:20,240 --> 00:18:21,750 right off the bat for that there are more but those are the main ones we're 1068 00:18:21,750 --> 00:18:21,760 more but those are the main ones we're 1069 00:18:21,760 --> 00:18:24,470 more but those are the main ones we're going to use for right now 1070 00:18:24,470 --> 00:18:24,480 going to use for right now 1071 00:18:24,480 --> 00:18:26,630 going to use for right now dynamic state create info does pretty 1072 00:18:26,630 --> 00:18:26,640 dynamic state create info does pretty 1073 00:18:26,640 --> 00:18:28,630 dynamic state create info does pretty much what you think it might where it 1074 00:18:28,630 --> 00:18:28,640 much what you think it might where it 1075 00:18:28,640 --> 00:18:30,630 much what you think it might where it takes basically this information here 1076 00:18:30,630 --> 00:18:30,640 takes basically this information here 1077 00:18:30,640 --> 00:18:34,150 takes basically this information here and jams it into a structure 1078 00:18:34,150 --> 00:18:34,160 and jams it into a structure 1079 00:18:34,160 --> 00:18:36,470 and jams it into a structure that tells the pipeline how that stuff 1080 00:18:36,470 --> 00:18:36,480 that tells the pipeline how that stuff 1081 00:18:36,480 --> 00:18:38,230 that tells the pipeline how that stuff is going to be used 1082 00:18:38,230 --> 00:18:38,240 is going to be used 1083 00:18:38,240 --> 00:18:40,070 is going to be used now 1084 00:18:40,070 --> 00:18:40,080 now 1085 00:18:40,080 --> 00:18:41,110 now the 1086 00:18:41,110 --> 00:18:41,120 the 1087 00:18:41,120 --> 00:18:43,430 the next thing that we're going to create is 1088 00:18:43,430 --> 00:18:43,440 next thing that we're going to create is 1089 00:18:43,440 --> 00:18:45,510 next thing that we're going to create is something called our vertex input and we 1090 00:18:45,510 --> 00:18:45,520 something called our vertex input and we 1091 00:18:45,520 --> 00:18:47,190 something called our vertex input and we haven't really touched on vertexes too 1092 00:18:47,190 --> 00:18:47,200 haven't really touched on vertexes too 1093 00:18:47,200 --> 00:18:48,230 haven't really touched on vertexes too much 1094 00:18:48,230 --> 00:18:48,240 much 1095 00:18:48,240 --> 00:18:50,070 much and as we can see we have a type here we 1096 00:18:50,070 --> 00:18:50,080 and as we can see we have a type here we 1097 00:18:50,080 --> 00:18:52,150 and as we can see we have a type here we have not defined 1098 00:18:52,150 --> 00:18:52,160 have not defined 1099 00:18:52,160 --> 00:18:53,029 have not defined so 1100 00:18:53,029 --> 00:18:53,039 so 1101 00:18:53,039 --> 00:18:55,590 so let me stop for a second and describe 1102 00:18:55,590 --> 00:18:55,600 let me stop for a second and describe 1103 00:18:55,600 --> 00:18:56,789 let me stop for a second and describe what we're talking about when we say 1104 00:18:56,789 --> 00:18:56,799 what we're talking about when we say 1105 00:18:56,799 --> 00:18:58,950 what we're talking about when we say vertex so a vertex 1106 00:18:58,950 --> 00:18:58,960 vertex so a vertex 1107 00:18:58,960 --> 00:19:02,710 vertex so a vertex is a individual point of geometry 1108 00:19:02,710 --> 00:19:02,720 is a individual point of geometry 1109 00:19:02,720 --> 00:19:05,510 is a individual point of geometry that holds various information and that 1110 00:19:05,510 --> 00:19:05,520 that holds various information and that 1111 00:19:05,520 --> 00:19:07,830 that holds various information and that information tends to include not only 1112 00:19:07,830 --> 00:19:07,840 information tends to include not only 1113 00:19:07,840 --> 00:19:10,070 information tends to include not only positional information so xyz to tell 1114 00:19:10,070 --> 00:19:10,080 positional information so xyz to tell 1115 00:19:10,080 --> 00:19:12,950 positional information so xyz to tell you where that that point in space is 1116 00:19:12,950 --> 00:19:12,960 you where that that point in space is 1117 00:19:12,960 --> 00:19:15,830 you where that that point in space is but it also holds things like your 1118 00:19:15,830 --> 00:19:15,840 but it also holds things like your 1119 00:19:15,840 --> 00:19:18,070 but it also holds things like your texture mapping coordinates 1120 00:19:18,070 --> 00:19:18,080 texture mapping coordinates 1121 00:19:18,080 --> 00:19:21,430 texture mapping coordinates it can hold things such as color it can 1122 00:19:21,430 --> 00:19:21,440 it can hold things such as color it can 1123 00:19:21,440 --> 00:19:22,950 it can hold things such as color it can hold 1124 00:19:22,950 --> 00:19:22,960 hold 1125 00:19:22,960 --> 00:19:25,190 hold lots of different information and you 1126 00:19:25,190 --> 00:19:25,200 lots of different information and you 1127 00:19:25,200 --> 00:19:27,350 lots of different information and you can generally put whatever you want in 1128 00:19:27,350 --> 00:19:27,360 can generally put whatever you want in 1129 00:19:27,360 --> 00:19:28,390 can generally put whatever you want in there but 1130 00:19:28,390 --> 00:19:28,400 there but 1131 00:19:28,400 --> 00:19:29,909 there but keep in mind that the larger you make 1132 00:19:29,909 --> 00:19:29,919 keep in mind that the larger you make 1133 00:19:29,919 --> 00:19:31,909 keep in mind that the larger you make your vertex 1134 00:19:31,909 --> 00:19:31,919 your vertex 1135 00:19:31,919 --> 00:19:33,270 your vertex the larger 1136 00:19:33,270 --> 00:19:33,280 the larger 1137 00:19:33,280 --> 00:19:35,590 the larger or the more information has to be pushed 1138 00:19:35,590 --> 00:19:35,600 or the more information has to be pushed 1139 00:19:35,600 --> 00:19:37,830 or the more information has to be pushed to the gpu every single time you upload 1140 00:19:37,830 --> 00:19:37,840 to the gpu every single time you upload 1141 00:19:37,840 --> 00:19:40,549 to the gpu every single time you upload geometry so when you upload geometry 1142 00:19:40,549 --> 00:19:40,559 geometry so when you upload geometry 1143 00:19:40,559 --> 00:19:43,590 geometry so when you upload geometry it's in the form of this vertex 1144 00:19:43,590 --> 00:19:43,600 it's in the form of this vertex 1145 00:19:43,600 --> 00:19:45,590 it's in the form of this vertex structure that you create 1146 00:19:45,590 --> 00:19:45,600 structure that you create 1147 00:19:45,600 --> 00:19:47,430 structure that you create and in this case we're going to create 1148 00:19:47,430 --> 00:19:47,440 and in this case we're going to create 1149 00:19:47,440 --> 00:19:49,830 and in this case we're going to create something called vertex 3d 1150 00:19:49,830 --> 00:19:49,840 something called vertex 3d 1151 00:19:49,840 --> 00:19:51,669 something called vertex 3d and so what this is is this is basically 1152 00:19:51,669 --> 00:19:51,679 and so what this is is this is basically 1153 00:19:51,679 --> 00:19:53,990 and so what this is is this is basically saying this is what that vertex kind of 1154 00:19:53,990 --> 00:19:54,000 saying this is what that vertex kind of 1155 00:19:54,000 --> 00:19:56,070 saying this is what that vertex kind of looks like and how to use it 1156 00:19:56,070 --> 00:19:56,080 looks like and how to use it 1157 00:19:56,080 --> 00:19:58,870 looks like and how to use it and so uh this stride right here is 1158 00:19:58,870 --> 00:19:58,880 and so uh this stride right here is 1159 00:19:58,880 --> 00:20:01,350 and so uh this stride right here is basically telling us how many bytes 1160 00:20:01,350 --> 00:20:01,360 basically telling us how many bytes 1161 00:20:01,360 --> 00:20:03,830 basically telling us how many bytes the vertex each vertex is and then the 1162 00:20:03,830 --> 00:20:03,840 the vertex each vertex is and then the 1163 00:20:03,840 --> 00:20:06,470 the vertex each vertex is and then the input rate is basically saying the 1164 00:20:06,470 --> 00:20:06,480 input rate is basically saying the 1165 00:20:06,480 --> 00:20:08,950 input rate is basically saying the input rate is one per vertex right 1166 00:20:08,950 --> 00:20:08,960 input rate is one per vertex right 1167 00:20:08,960 --> 00:20:11,909 input rate is one per vertex right so uh we move to the next entry for each 1168 00:20:11,909 --> 00:20:11,919 so uh we move to the next entry for each 1169 00:20:11,919 --> 00:20:14,070 so uh we move to the next entry for each individual vertex 1170 00:20:14,070 --> 00:20:14,080 individual vertex 1171 00:20:14,080 --> 00:20:15,669 individual vertex so before we move on 1172 00:20:15,669 --> 00:20:15,679 so before we move on 1173 00:20:15,679 --> 00:20:17,590 so before we move on we should probably go ahead and define 1174 00:20:17,590 --> 00:20:17,600 we should probably go ahead and define 1175 00:20:17,600 --> 00:20:19,590 we should probably go ahead and define vertex 3d right 1176 00:20:19,590 --> 00:20:19,600 vertex 3d right 1177 00:20:19,600 --> 00:20:21,110 vertex 3d right because it's definitely something that 1178 00:20:21,110 --> 00:20:21,120 because it's definitely something that 1179 00:20:21,120 --> 00:20:23,909 because it's definitely something that we're going to need to know 1180 00:20:23,909 --> 00:20:23,919 we're going to need to know 1181 00:20:23,919 --> 00:20:25,510 we're going to need to know so to define this we actually are going 1182 00:20:25,510 --> 00:20:25,520 so to define this we actually are going 1183 00:20:25,520 --> 00:20:27,590 so to define this we actually are going to go into math types 1184 00:20:27,590 --> 00:20:27,600 to go into math types 1185 00:20:27,600 --> 00:20:29,830 to go into math types so that is going to be under math 1186 00:20:29,830 --> 00:20:29,840 so that is going to be under math 1187 00:20:29,840 --> 00:20:31,590 so that is going to be under math math types 1188 00:20:31,590 --> 00:20:31,600 math types 1189 00:20:31,600 --> 00:20:35,190 math types and we're going to go here to the bottom 1190 00:20:35,190 --> 00:20:35,200 and we're going to go here to the bottom 1191 00:20:35,200 --> 00:20:38,149 and we're going to go here to the bottom and we'll go ahead and put 1192 00:20:38,149 --> 00:20:38,159 and we'll go ahead and put 1193 00:20:38,159 --> 00:20:40,070 and we'll go ahead and put our definition right there so we're 1194 00:20:40,070 --> 00:20:40,080 our definition right there so we're 1195 00:20:40,080 --> 00:20:41,590 our definition right there so we're going to type def structure called 1196 00:20:41,590 --> 00:20:41,600 going to type def structure called 1197 00:20:41,600 --> 00:20:43,990 going to type def structure called vertex 3d 1198 00:20:43,990 --> 00:20:44,000 vertex 3d 1199 00:20:44,000 --> 00:20:45,830 vertex 3d to be called vertex 3d so we don't have 1200 00:20:45,830 --> 00:20:45,840 to be called vertex 3d so we don't have 1201 00:20:45,840 --> 00:20:47,430 to be called vertex 3d so we don't have to type this 1202 00:20:47,430 --> 00:20:47,440 to type this 1203 00:20:47,440 --> 00:20:49,190 to type this and then for right now all we're 1204 00:20:49,190 --> 00:20:49,200 and then for right now all we're 1205 00:20:49,200 --> 00:20:50,789 and then for right now all we're actually going to store in here is 1206 00:20:50,789 --> 00:20:50,799 actually going to store in here is 1207 00:20:50,799 --> 00:20:53,110 actually going to store in here is position right and like i said there are 1208 00:20:53,110 --> 00:20:53,120 position right and like i said there are 1209 00:20:53,120 --> 00:20:54,070 position right and like i said there are going to be other things that we're 1210 00:20:54,070 --> 00:20:54,080 going to be other things that we're 1211 00:20:54,080 --> 00:20:55,830 going to be other things that we're going to be adding to this 1212 00:20:55,830 --> 00:20:55,840 going to be adding to this 1213 00:20:55,840 --> 00:20:57,190 going to be adding to this but for right now i want to keep things 1214 00:20:57,190 --> 00:20:57,200 but for right now i want to keep things 1215 00:20:57,200 --> 00:20:58,630 but for right now i want to keep things simple until we actually get stuff up 1216 00:20:58,630 --> 00:20:58,640 simple until we actually get stuff up 1217 00:20:58,640 --> 00:20:59,909 simple until we actually get stuff up and running and then i'll come back and 1218 00:20:59,909 --> 00:20:59,919 and running and then i'll come back and 1219 00:20:59,919 --> 00:21:02,630 and running and then i'll come back and add properties to this as we go so for 1220 00:21:02,630 --> 00:21:02,640 add properties to this as we go so for 1221 00:21:02,640 --> 00:21:04,870 add properties to this as we go so for right now we're just storing position 1222 00:21:04,870 --> 00:21:04,880 right now we're just storing position 1223 00:21:04,880 --> 00:21:05,909 right now we're just storing position okay 1224 00:21:05,909 --> 00:21:05,919 okay 1225 00:21:05,919 --> 00:21:07,830 okay so now that we have our vertex 3d we can 1226 00:21:07,830 --> 00:21:07,840 so now that we have our vertex 3d we can 1227 00:21:07,840 --> 00:21:09,350 so now that we have our vertex 3d we can go back 1228 00:21:09,350 --> 00:21:09,360 go back 1229 00:21:09,360 --> 00:21:10,950 go back and we need to 1230 00:21:10,950 --> 00:21:10,960 and we need to 1231 00:21:10,960 --> 00:21:12,230 and we need to include 1232 00:21:12,230 --> 00:21:12,240 include 1233 00:21:12,240 --> 00:21:12,950 include the 1234 00:21:12,950 --> 00:21:12,960 the 1235 00:21:12,960 --> 00:21:14,710 the math types 1236 00:21:14,710 --> 00:21:14,720 math types 1237 00:21:14,720 --> 00:21:16,440 math types in this file 1238 00:21:16,440 --> 00:21:16,450 in this file 1239 00:21:16,450 --> 00:21:17,590 in this file [Music] 1240 00:21:17,590 --> 00:21:17,600 [Music] 1241 00:21:17,600 --> 00:21:18,630 [Music] so 1242 00:21:18,630 --> 00:21:18,640 so 1243 00:21:18,640 --> 00:21:22,149 so here i'll say include 1244 00:21:22,149 --> 00:21:22,159 1245 00:21:22,159 --> 00:21:23,350 math 1246 00:21:23,350 --> 00:21:23,360 math 1247 00:21:23,360 --> 00:21:27,510 math mathtypes.h 1248 00:21:27,510 --> 00:21:27,520 1249 00:21:27,520 --> 00:21:29,110 and now if we go ahead and save that we 1250 00:21:29,110 --> 00:21:29,120 and now if we go ahead and save that we 1251 00:21:29,120 --> 00:21:31,510 and now if we go ahead and save that we see that vertex 3d is defined 1252 00:21:31,510 --> 00:21:31,520 see that vertex 3d is defined 1253 00:21:31,520 --> 00:21:32,870 see that vertex 3d is defined so the reason we take 1254 00:21:32,870 --> 00:21:32,880 so the reason we take 1255 00:21:32,880 --> 00:21:34,470 so the reason we take the size of this is because this is 1256 00:21:34,470 --> 00:21:34,480 the size of this is because this is 1257 00:21:34,480 --> 00:21:35,590 the size of this is because this is going to be changing we don't have to 1258 00:21:35,590 --> 00:21:35,600 going to be changing we don't have to 1259 00:21:35,600 --> 00:21:37,029 going to be changing we don't have to have to come back in here every single 1260 00:21:37,029 --> 00:21:37,039 have to come back in here every single 1261 00:21:37,039 --> 00:21:38,470 have to come back in here every single time and change this 1262 00:21:38,470 --> 00:21:38,480 time and change this 1263 00:21:38,480 --> 00:21:39,909 time and change this although there will be parts that we 1264 00:21:39,909 --> 00:21:39,919 although there will be parts that we 1265 00:21:39,919 --> 00:21:41,830 although there will be parts that we will have to come back here and change i 1266 00:21:41,830 --> 00:21:41,840 will have to come back here and change i 1267 00:21:41,840 --> 00:21:44,149 will have to come back here and change i don't want this to be one of them so 1268 00:21:44,149 --> 00:21:44,159 don't want this to be one of them so 1269 00:21:44,159 --> 00:21:46,230 don't want this to be one of them so we'll take the size of that in bytes and 1270 00:21:46,230 --> 00:21:46,240 we'll take the size of that in bytes and 1271 00:21:46,240 --> 00:21:49,990 we'll take the size of that in bytes and use that instead 1272 00:21:49,990 --> 00:21:50,000 1273 00:21:50,000 --> 00:21:52,070 okay 1274 00:21:52,070 --> 00:21:52,080 okay 1275 00:21:52,080 --> 00:21:54,710 okay next we have something called attributes 1276 00:21:54,710 --> 00:21:54,720 next we have something called attributes 1277 00:21:54,720 --> 00:21:56,630 next we have something called attributes and this is basically how 1278 00:21:56,630 --> 00:21:56,640 and this is basically how 1279 00:21:56,640 --> 00:21:59,510 and this is basically how each individual vertex is split up 1280 00:21:59,510 --> 00:21:59,520 each individual vertex is split up 1281 00:21:59,520 --> 00:22:04,789 each individual vertex is split up so if we recall in our 1282 00:22:04,789 --> 00:22:04,799 1283 00:22:04,799 --> 00:22:06,950 our vertex shader here actually let me 1284 00:22:06,950 --> 00:22:06,960 our vertex shader here actually let me 1285 00:22:06,960 --> 00:22:08,870 our vertex shader here actually let me open the one 1286 00:22:08,870 --> 00:22:08,880 open the one 1287 00:22:08,880 --> 00:22:11,430 open the one here 1288 00:22:11,430 --> 00:22:11,440 1289 00:22:11,440 --> 00:22:14,390 we have this layout location zero in 1290 00:22:14,390 --> 00:22:14,400 we have this layout location zero in 1291 00:22:14,400 --> 00:22:16,630 we have this layout location zero in vec3 imposition 1292 00:22:16,630 --> 00:22:16,640 vec3 imposition 1293 00:22:16,640 --> 00:22:19,510 vec3 imposition this is actually an attribute so what we 1294 00:22:19,510 --> 00:22:19,520 this is actually an attribute so what we 1295 00:22:19,520 --> 00:22:21,750 this is actually an attribute so what we are saying here is uh the location zero 1296 00:22:21,750 --> 00:22:21,760 are saying here is uh the location zero 1297 00:22:21,760 --> 00:22:23,029 are saying here is uh the location zero equals zero 1298 00:22:23,029 --> 00:22:23,039 equals zero 1299 00:22:23,039 --> 00:22:24,470 equals zero is basically saying this is the first 1300 00:22:24,470 --> 00:22:24,480 is basically saying this is the first 1301 00:22:24,480 --> 00:22:27,350 is basically saying this is the first attribute and it is of type vector3 so 1302 00:22:27,350 --> 00:22:27,360 attribute and it is of type vector3 so 1303 00:22:27,360 --> 00:22:29,029 attribute and it is of type vector3 so the shader actually knows how to 1304 00:22:29,029 --> 00:22:29,039 the shader actually knows how to 1305 00:22:29,039 --> 00:22:31,350 the shader actually knows how to interpret that so every time we add an 1306 00:22:31,350 --> 00:22:31,360 interpret that so every time we add an 1307 00:22:31,360 --> 00:22:32,710 interpret that so every time we add an attribute 1308 00:22:32,710 --> 00:22:32,720 attribute 1309 00:22:32,720 --> 00:22:34,470 attribute we are going to be adding one of these 1310 00:22:34,470 --> 00:22:34,480 we are going to be adding one of these 1311 00:22:34,480 --> 00:22:36,870 we are going to be adding one of these things and an attribute is loaded as 1312 00:22:36,870 --> 00:22:36,880 things and an attribute is loaded as 1313 00:22:36,880 --> 00:22:39,190 things and an attribute is loaded as part of a vertex so 1314 00:22:39,190 --> 00:22:39,200 part of a vertex so 1315 00:22:39,200 --> 00:22:41,029 part of a vertex so this is just a way for us to be able to 1316 00:22:41,029 --> 00:22:41,039 this is just a way for us to be able to 1317 00:22:41,039 --> 00:22:43,270 this is just a way for us to be able to split these things up programmatically 1318 00:22:43,270 --> 00:22:43,280 split these things up programmatically 1319 00:22:43,280 --> 00:22:44,710 split these things up programmatically so that the shader actually knows what 1320 00:22:44,710 --> 00:22:44,720 so that the shader actually knows what 1321 00:22:44,720 --> 00:22:46,549 so that the shader actually knows what it's dealing with right and so we're 1322 00:22:46,549 --> 00:22:46,559 it's dealing with right and so we're 1323 00:22:46,559 --> 00:22:48,230 it's dealing with right and so we're actually going to be including an 1324 00:22:48,230 --> 00:22:48,240 actually going to be including an 1325 00:22:48,240 --> 00:22:50,870 actually going to be including an attribute count as well as attributes 1326 00:22:50,870 --> 00:22:50,880 attribute count as well as attributes 1327 00:22:50,880 --> 00:22:53,110 attribute count as well as attributes listing to say how this guy is actually 1328 00:22:53,110 --> 00:22:53,120 listing to say how this guy is actually 1329 00:22:53,120 --> 00:22:54,789 listing to say how this guy is actually split up okay we should probably make 1330 00:22:54,789 --> 00:22:54,799 split up okay we should probably make 1331 00:22:54,799 --> 00:22:56,470 split up okay we should probably make this guy configurable too but for right 1332 00:22:56,470 --> 00:22:56,480 this guy configurable too but for right 1333 00:22:56,480 --> 00:22:58,390 this guy configurable too but for right now i'm not going to worry about it 1334 00:22:58,390 --> 00:22:58,400 now i'm not going to worry about it 1335 00:22:58,400 --> 00:23:01,510 now i'm not going to worry about it okay so that is what attributes are on a 1336 00:23:01,510 --> 00:23:01,520 okay so that is what attributes are on a 1337 00:23:01,520 --> 00:23:03,110 okay so that is what attributes are on a high level 1338 00:23:03,110 --> 00:23:03,120 high level 1339 00:23:03,120 --> 00:23:05,909 high level and how they're used 1340 00:23:05,909 --> 00:23:05,919 and how they're used 1341 00:23:05,919 --> 00:23:06,950 and how they're used okay 1342 00:23:06,950 --> 00:23:06,960 okay 1343 00:23:06,960 --> 00:23:09,270 okay so the next thing is we have to define 1344 00:23:09,270 --> 00:23:09,280 so the next thing is we have to define 1345 00:23:09,280 --> 00:23:11,430 so the next thing is we have to define input assembly and that is basically 1346 00:23:11,430 --> 00:23:11,440 input assembly and that is basically 1347 00:23:11,440 --> 00:23:13,990 input assembly and that is basically what takes this information and 1348 00:23:13,990 --> 00:23:14,000 what takes this information and 1349 00:23:14,000 --> 00:23:15,909 what takes this information and assembles it into a form that the vertex 1350 00:23:15,909 --> 00:23:15,919 assembles it into a form that the vertex 1351 00:23:15,919 --> 00:23:17,909 assembles it into a form that the vertex shader can then use 1352 00:23:17,909 --> 00:23:17,919 shader can then use 1353 00:23:17,919 --> 00:23:19,990 shader can then use so in this case what we're going to do 1354 00:23:19,990 --> 00:23:20,000 so in this case what we're going to do 1355 00:23:20,000 --> 00:23:21,909 so in this case what we're going to do is we're just going to say that the 1356 00:23:21,909 --> 00:23:21,919 is we're just going to say that the 1357 00:23:21,919 --> 00:23:24,470 is we're just going to say that the topology type that we want to use is 1358 00:23:24,470 --> 00:23:24,480 topology type that we want to use is 1359 00:23:24,480 --> 00:23:27,110 topology type that we want to use is primitive topology triangle list which 1360 00:23:27,110 --> 00:23:27,120 primitive topology triangle list which 1361 00:23:27,120 --> 00:23:29,350 primitive topology triangle list which is basically saying all of our geometry 1362 00:23:29,350 --> 00:23:29,360 is basically saying all of our geometry 1363 00:23:29,360 --> 00:23:31,270 is basically saying all of our geometry is expected to be triangles now we could 1364 00:23:31,270 --> 00:23:31,280 is expected to be triangles now we could 1365 00:23:31,280 --> 00:23:33,029 is expected to be triangles now we could use quads if we wanted to we might do 1366 00:23:33,029 --> 00:23:33,039 use quads if we wanted to we might do 1367 00:23:33,039 --> 00:23:35,110 use quads if we wanted to we might do that 1368 00:23:35,110 --> 00:23:35,120 that 1369 00:23:35,120 --> 00:23:37,029 that in the future but at least for now 1370 00:23:37,029 --> 00:23:37,039 in the future but at least for now 1371 00:23:37,039 --> 00:23:38,470 in the future but at least for now everything we're going to do is with 1372 00:23:38,470 --> 00:23:38,480 everything we're going to do is with 1373 00:23:38,480 --> 00:23:40,230 everything we're going to do is with triangles 1374 00:23:40,230 --> 00:23:40,240 triangles 1375 00:23:40,240 --> 00:23:43,190 triangles okay and then 1376 00:23:43,190 --> 00:23:43,200 okay and then 1377 00:23:43,200 --> 00:23:46,070 okay and then our pipeline layout 1378 00:23:46,070 --> 00:23:46,080 our pipeline layout 1379 00:23:46,080 --> 00:23:48,789 our pipeline layout is basically going to start off by 1380 00:23:48,789 --> 00:23:48,799 is basically going to start off by 1381 00:23:48,799 --> 00:23:50,710 is basically going to start off by just setting the vk structure type and 1382 00:23:50,710 --> 00:23:50,720 just setting the vk structure type and 1383 00:23:50,720 --> 00:23:52,710 just setting the vk structure type and zeroing out the rest 1384 00:23:52,710 --> 00:23:52,720 zeroing out the rest 1385 00:23:52,720 --> 00:23:54,710 zeroing out the rest the next thing that we're going to do is 1386 00:23:54,710 --> 00:23:54,720 the next thing that we're going to do is 1387 00:23:54,720 --> 00:23:56,950 the next thing that we're going to do is we are going to utilize something called 1388 00:23:56,950 --> 00:23:56,960 we are going to utilize something called 1389 00:23:56,960 --> 00:23:58,870 we are going to utilize something called descriptor sets or at least the layouts 1390 00:23:58,870 --> 00:23:58,880 descriptor sets or at least the layouts 1391 00:23:58,880 --> 00:24:00,390 descriptor sets or at least the layouts of that 1392 00:24:00,390 --> 00:24:00,400 of that 1393 00:24:00,400 --> 00:24:02,310 of that and i'll come back to this but this 1394 00:24:02,310 --> 00:24:02,320 and i'll come back to this but this 1395 00:24:02,320 --> 00:24:03,590 and i'll come back to this but this basically has to do with something 1396 00:24:03,590 --> 00:24:03,600 basically has to do with something 1397 00:24:03,600 --> 00:24:05,110 basically has to do with something called uniforms 1398 00:24:05,110 --> 00:24:05,120 called uniforms 1399 00:24:05,120 --> 00:24:06,710 called uniforms which are various parameters that we can 1400 00:24:06,710 --> 00:24:06,720 which are various parameters that we can 1401 00:24:06,720 --> 00:24:09,269 which are various parameters that we can pass to our 1402 00:24:09,269 --> 00:24:09,279 pass to our 1403 00:24:09,279 --> 00:24:10,470 pass to our program 1404 00:24:10,470 --> 00:24:10,480 program 1405 00:24:10,480 --> 00:24:13,029 program that are not necessarily vertex specific 1406 00:24:13,029 --> 00:24:13,039 that are not necessarily vertex specific 1407 00:24:13,039 --> 00:24:15,830 that are not necessarily vertex specific but that can be 1408 00:24:15,830 --> 00:24:15,840 1409 00:24:15,840 --> 00:24:17,269 that can be passed in to give us 1410 00:24:17,269 --> 00:24:17,279 that can be passed in to give us 1411 00:24:17,279 --> 00:24:19,510 that can be passed in to give us additional information that we need 1412 00:24:19,510 --> 00:24:19,520 additional information that we need 1413 00:24:19,520 --> 00:24:21,190 additional information that we need for the render 1414 00:24:21,190 --> 00:24:21,200 for the render 1415 00:24:21,200 --> 00:24:23,430 for the render okay and so 1416 00:24:23,430 --> 00:24:23,440 okay and so 1417 00:24:23,440 --> 00:24:26,549 okay and so what we wind up with is all of this 1418 00:24:26,549 --> 00:24:26,559 what we wind up with is all of this 1419 00:24:26,559 --> 00:24:28,789 what we wind up with is all of this information that we take here 1420 00:24:28,789 --> 00:24:28,799 information that we take here 1421 00:24:28,799 --> 00:24:30,830 information that we take here winds up being part of 1422 00:24:30,830 --> 00:24:30,840 winds up being part of 1423 00:24:30,840 --> 00:24:34,230 winds up being part of a pipeline layout so this here 1424 00:24:34,230 --> 00:24:34,240 a pipeline layout so this here 1425 00:24:34,240 --> 00:24:36,710 a pipeline layout so this here determines what the format 1426 00:24:36,710 --> 00:24:36,720 determines what the format 1427 00:24:36,720 --> 00:24:38,870 determines what the format of our pipeline will be 1428 00:24:38,870 --> 00:24:38,880 of our pipeline will be 1429 00:24:38,880 --> 00:24:42,549 of our pipeline will be so the next logical step is to call 1430 00:24:42,549 --> 00:24:42,559 so the next logical step is to call 1431 00:24:42,559 --> 00:24:44,789 so the next logical step is to call vk create pipeline layout 1432 00:24:44,789 --> 00:24:44,799 vk create pipeline layout 1433 00:24:44,799 --> 00:24:46,549 vk create pipeline layout and we basically just pass 1434 00:24:46,549 --> 00:24:46,559 and we basically just pass 1435 00:24:46,559 --> 00:24:49,430 and we basically just pass all of the stuff that we just wound up 1436 00:24:49,430 --> 00:24:49,440 all of the stuff that we just wound up 1437 00:24:49,440 --> 00:24:51,029 all of the stuff that we just wound up actually creating 1438 00:24:51,029 --> 00:24:51,039 actually creating 1439 00:24:51,039 --> 00:24:52,310 actually creating so 1440 00:24:52,310 --> 00:24:52,320 so 1441 00:24:52,320 --> 00:24:55,110 so our pipeline layout create info here um 1442 00:24:55,110 --> 00:24:55,120 our pipeline layout create info here um 1443 00:24:55,120 --> 00:24:56,630 our pipeline layout create info here um is basically the glue that holds all 1444 00:24:56,630 --> 00:24:56,640 is basically the glue that holds all 1445 00:24:56,640 --> 00:24:58,870 is basically the glue that holds all that stuff together okay 1446 00:24:58,870 --> 00:24:58,880 that stuff together okay 1447 00:24:58,880 --> 00:25:01,110 that stuff together okay and so we create that 1448 00:25:01,110 --> 00:25:01,120 and so we create that 1449 00:25:01,120 --> 00:25:03,830 and so we create that and then we actually create our pipeline 1450 00:25:03,830 --> 00:25:03,840 and then we actually create our pipeline 1451 00:25:03,840 --> 00:25:04,789 and then we actually create our pipeline itself 1452 00:25:04,789 --> 00:25:04,799 itself 1453 00:25:04,799 --> 00:25:06,390 itself below here 1454 00:25:06,390 --> 00:25:06,400 below here 1455 00:25:06,400 --> 00:25:08,789 below here starting off with a create info just as 1456 00:25:08,789 --> 00:25:08,799 starting off with a create info just as 1457 00:25:08,799 --> 00:25:10,310 starting off with a create info just as you do for a lot of other things in 1458 00:25:10,310 --> 00:25:10,320 you do for a lot of other things in 1459 00:25:10,320 --> 00:25:11,510 you do for a lot of other things in vulcan 1460 00:25:11,510 --> 00:25:11,520 vulcan 1461 00:25:11,520 --> 00:25:13,269 vulcan and so here is where we pass things like 1462 00:25:13,269 --> 00:25:13,279 and so here is where we pass things like 1463 00:25:13,279 --> 00:25:15,029 and so here is where we pass things like what the stage count is what those 1464 00:25:15,029 --> 00:25:15,039 what the stage count is what those 1465 00:25:15,039 --> 00:25:17,110 what the stage count is what those individual stages are 1466 00:25:17,110 --> 00:25:17,120 individual stages are 1467 00:25:17,120 --> 00:25:19,430 individual stages are the vertex input the 1468 00:25:19,430 --> 00:25:19,440 the vertex input the 1469 00:25:19,440 --> 00:25:21,350 the vertex input the input assembly state 1470 00:25:21,350 --> 00:25:21,360 input assembly state 1471 00:25:21,360 --> 00:25:22,630 input assembly state so all these other things that we 1472 00:25:22,630 --> 00:25:22,640 so all these other things that we 1473 00:25:22,640 --> 00:25:25,430 so all these other things that we created above right 1474 00:25:25,430 --> 00:25:25,440 created above right 1475 00:25:25,440 --> 00:25:27,669 created above right we are going to 1476 00:25:27,669 --> 00:25:27,679 we are going to 1477 00:25:27,679 --> 00:25:29,350 we are going to pass a bunch of other properties such as 1478 00:25:29,350 --> 00:25:29,360 pass a bunch of other properties such as 1479 00:25:29,360 --> 00:25:31,190 pass a bunch of other properties such as our viewport state our rasterization 1480 00:25:31,190 --> 00:25:31,200 our viewport state our rasterization 1481 00:25:31,200 --> 00:25:33,510 our viewport state our rasterization multi-sample so this is where all those 1482 00:25:33,510 --> 00:25:33,520 multi-sample so this is where all those 1483 00:25:33,520 --> 00:25:36,149 multi-sample so this is where all those pieces above are actually used 1484 00:25:36,149 --> 00:25:36,159 pieces above are actually used 1485 00:25:36,159 --> 00:25:37,350 pieces above are actually used and then tessellation state we're 1486 00:25:37,350 --> 00:25:37,360 and then tessellation state we're 1487 00:25:37,360 --> 00:25:38,549 and then tessellation state we're actually not using so i'm just hard 1488 00:25:38,549 --> 00:25:38,559 actually not using so i'm just hard 1489 00:25:38,559 --> 00:25:40,310 actually not using so i'm just hard coding that to zero just to be explicit 1490 00:25:40,310 --> 00:25:40,320 coding that to zero just to be explicit 1491 00:25:40,320 --> 00:25:42,390 coding that to zero just to be explicit about it 1492 00:25:42,390 --> 00:25:42,400 about it 1493 00:25:42,400 --> 00:25:44,310 about it and then 1494 00:25:44,310 --> 00:25:44,320 and then 1495 00:25:44,320 --> 00:25:46,549 and then the pipeline layout we're going to use 1496 00:25:46,549 --> 00:25:46,559 the pipeline layout we're going to use 1497 00:25:46,559 --> 00:25:49,510 the pipeline layout we're going to use is the layout that we just defined here 1498 00:25:49,510 --> 00:25:49,520 is the layout that we just defined here 1499 00:25:49,520 --> 00:25:51,110 is the layout that we just defined here right so we create this 1500 00:25:51,110 --> 00:25:51,120 right so we create this 1501 00:25:51,120 --> 00:25:54,149 right so we create this there use it here 1502 00:25:54,149 --> 00:25:54,159 there use it here 1503 00:25:54,159 --> 00:25:56,149 there use it here and then we are going to add a couple 1504 00:25:56,149 --> 00:25:56,159 and then we are going to add a couple 1505 00:25:56,159 --> 00:25:58,149 and then we are going to add a couple more things to this so we have the 1506 00:25:58,149 --> 00:25:58,159 more things to this so we have the 1507 00:25:58,159 --> 00:26:01,269 more things to this so we have the render pass which is passed in um 1508 00:26:01,269 --> 00:26:01,279 render pass which is passed in um 1509 00:26:01,279 --> 00:26:03,190 render pass which is passed in um just passed in to us 1510 00:26:03,190 --> 00:26:03,200 just passed in to us 1511 00:26:03,200 --> 00:26:04,950 just passed in to us any subpasses that we use we're not 1512 00:26:04,950 --> 00:26:04,960 any subpasses that we use we're not 1513 00:26:04,960 --> 00:26:06,340 any subpasses that we use we're not using subpasses just yet 1514 00:26:06,340 --> 00:26:06,350 using subpasses just yet 1515 00:26:06,350 --> 00:26:07,510 using subpasses just yet [Music] 1516 00:26:07,510 --> 00:26:07,520 [Music] 1517 00:26:07,520 --> 00:26:09,909 [Music] and then we don't have base pipelines or 1518 00:26:09,909 --> 00:26:09,919 and then we don't have base pipelines or 1519 00:26:09,919 --> 00:26:11,269 and then we don't have base pipelines or base pipeline 1520 00:26:11,269 --> 00:26:11,279 base pipeline 1521 00:26:11,279 --> 00:26:13,430 base pipeline indices so we're just sort of nulling 1522 00:26:13,430 --> 00:26:13,440 indices so we're just sort of nulling 1523 00:26:13,440 --> 00:26:15,669 indices so we're just sort of nulling that out okay 1524 00:26:15,669 --> 00:26:15,679 that out okay 1525 00:26:15,679 --> 00:26:18,310 that out okay and so at this point we're finally ready 1526 00:26:18,310 --> 00:26:18,320 and so at this point we're finally ready 1527 00:26:18,320 --> 00:26:20,789 and so at this point we're finally ready to create our pipeline 1528 00:26:20,789 --> 00:26:20,799 to create our pipeline 1529 00:26:20,799 --> 00:26:24,710 to create our pipeline and uh this just is a call to vk create 1530 00:26:24,710 --> 00:26:24,720 and uh this just is a call to vk create 1531 00:26:24,720 --> 00:26:26,230 and uh this just is a call to vk create graphics pipelines you'll note that this 1532 00:26:26,230 --> 00:26:26,240 graphics pipelines you'll note that this 1533 00:26:26,240 --> 00:26:27,590 graphics pipelines you'll note that this is plural because you can create more 1534 00:26:27,590 --> 00:26:27,600 is plural because you can create more 1535 00:26:27,600 --> 00:26:28,710 is plural because you can create more than one 1536 00:26:28,710 --> 00:26:28,720 than one 1537 00:26:28,720 --> 00:26:30,870 than one so if you were to create uh 1538 00:26:30,870 --> 00:26:30,880 so if you were to create uh 1539 00:26:30,880 --> 00:26:32,630 so if you were to create uh if you wanted to you could create two 1540 00:26:32,630 --> 00:26:32,640 if you wanted to you could create two 1541 00:26:32,640 --> 00:26:34,310 if you wanted to you could create two here and just have one 1542 00:26:34,310 --> 00:26:34,320 here and just have one 1543 00:26:34,320 --> 00:26:35,269 here and just have one be 1544 00:26:35,269 --> 00:26:35,279 be 1545 00:26:35,279 --> 00:26:37,110 be wireframe and the other not be wireframe 1546 00:26:37,110 --> 00:26:37,120 wireframe and the other not be wireframe 1547 00:26:37,120 --> 00:26:38,470 wireframe and the other not be wireframe for example 1548 00:26:38,470 --> 00:26:38,480 for example 1549 00:26:38,480 --> 00:26:39,750 for example and you could certainly use this to do 1550 00:26:39,750 --> 00:26:39,760 and you could certainly use this to do 1551 00:26:39,760 --> 00:26:42,470 and you could certainly use this to do that we're just going to be creating one 1552 00:26:42,470 --> 00:26:42,480 that we're just going to be creating one 1553 00:26:42,480 --> 00:26:45,990 that we're just going to be creating one passing the info and then 1554 00:26:45,990 --> 00:26:46,000 passing the info and then 1555 00:26:46,000 --> 00:26:47,750 passing the info and then obviously just setting 1556 00:26:47,750 --> 00:26:47,760 obviously just setting 1557 00:26:47,760 --> 00:26:49,830 obviously just setting our pipeline handle 1558 00:26:49,830 --> 00:26:49,840 our pipeline handle 1559 00:26:49,840 --> 00:26:51,190 our pipeline handle to that 1560 00:26:51,190 --> 00:26:51,200 to that 1561 00:26:51,200 --> 00:26:53,350 to that so we're going to take the result of 1562 00:26:53,350 --> 00:26:53,360 so we're going to take the result of 1563 00:26:53,360 --> 00:26:54,310 so we're going to take the result of that 1564 00:26:54,310 --> 00:26:54,320 that 1565 00:26:54,320 --> 00:26:58,230 that and we are going to double check it 1566 00:26:58,230 --> 00:26:58,240 and we are going to double check it 1567 00:26:58,240 --> 00:26:59,830 and we are going to double check it against success 1568 00:26:59,830 --> 00:26:59,840 against success 1569 00:26:59,840 --> 00:27:01,909 against success and if it is a success then we're going 1570 00:27:01,909 --> 00:27:01,919 and if it is a success then we're going 1571 00:27:01,919 --> 00:27:03,750 and if it is a success then we're going to go ahead 1572 00:27:03,750 --> 00:27:03,760 to go ahead 1573 00:27:03,760 --> 00:27:05,750 to go ahead and return true 1574 00:27:05,750 --> 00:27:05,760 and return true 1575 00:27:05,760 --> 00:27:07,750 and return true if for some reason we have an error we 1576 00:27:07,750 --> 00:27:07,760 if for some reason we have an error we 1577 00:27:07,760 --> 00:27:09,430 if for some reason we have an error we are actually going to 1578 00:27:09,430 --> 00:27:09,440 are actually going to 1579 00:27:09,440 --> 00:27:11,269 are actually going to bleat about that here 1580 00:27:11,269 --> 00:27:11,279 bleat about that here 1581 00:27:11,279 --> 00:27:13,430 bleat about that here saying um we failed and then with what 1582 00:27:13,430 --> 00:27:13,440 saying um we failed and then with what 1583 00:27:13,440 --> 00:27:15,190 saying um we failed and then with what error and get the vulcan error string 1584 00:27:15,190 --> 00:27:15,200 error and get the vulcan error string 1585 00:27:15,200 --> 00:27:17,430 error and get the vulcan error string here okay 1586 00:27:17,430 --> 00:27:17,440 here okay 1587 00:27:17,440 --> 00:27:19,430 here okay and that is all there is in terms of 1588 00:27:19,430 --> 00:27:19,440 and that is all there is in terms of 1589 00:27:19,440 --> 00:27:21,750 and that is all there is in terms of actual pipeline creation it's it's more 1590 00:27:21,750 --> 00:27:21,760 actual pipeline creation it's it's more 1591 00:27:21,760 --> 00:27:23,350 actual pipeline creation it's it's more just filling out structs than anything 1592 00:27:23,350 --> 00:27:23,360 just filling out structs than anything 1593 00:27:23,360 --> 00:27:24,789 just filling out structs than anything else there's not really 1594 00:27:24,789 --> 00:27:24,799 else there's not really 1595 00:27:24,799 --> 00:27:25,669 else there's not really much 1596 00:27:25,669 --> 00:27:25,679 much 1597 00:27:25,679 --> 00:27:28,710 much if any logic in here 1598 00:27:28,710 --> 00:27:28,720 if any logic in here 1599 00:27:28,720 --> 00:27:30,149 if any logic in here so uh 1600 00:27:30,149 --> 00:27:30,159 so uh 1601 00:27:30,159 --> 00:27:31,909 so uh the only other thing that we really need 1602 00:27:31,909 --> 00:27:31,919 the only other thing that we really need 1603 00:27:31,919 --> 00:27:33,909 the only other thing that we really need to fill out is the destroy which i'm 1604 00:27:33,909 --> 00:27:33,919 to fill out is the destroy which i'm 1605 00:27:33,919 --> 00:27:35,190 to fill out is the destroy which i'm actually just going to kind of plop in 1606 00:27:35,190 --> 00:27:35,200 actually just going to kind of plop in 1607 00:27:35,200 --> 00:27:37,110 actually just going to kind of plop in here all at once because it's pretty 1608 00:27:37,110 --> 00:27:37,120 here all at once because it's pretty 1609 00:27:37,120 --> 00:27:39,510 here all at once because it's pretty straightforward stuff 1610 00:27:39,510 --> 00:27:39,520 straightforward stuff 1611 00:27:39,520 --> 00:27:41,110 straightforward stuff so basically we just check to make sure 1612 00:27:41,110 --> 00:27:41,120 so basically we just check to make sure 1613 00:27:41,120 --> 00:27:42,630 so basically we just check to make sure the pipeline exists if there's a handle 1614 00:27:42,630 --> 00:27:42,640 the pipeline exists if there's a handle 1615 00:27:42,640 --> 00:27:45,669 the pipeline exists if there's a handle to it destroy it and then set it to zero 1616 00:27:45,669 --> 00:27:45,679 to it destroy it and then set it to zero 1617 00:27:45,679 --> 00:27:47,590 to it destroy it and then set it to zero and then also make sure to destroy the 1618 00:27:47,590 --> 00:27:47,600 and then also make sure to destroy the 1619 00:27:47,600 --> 00:27:49,269 and then also make sure to destroy the pipeline layout that we 1620 00:27:49,269 --> 00:27:49,279 pipeline layout that we 1621 00:27:49,279 --> 00:27:51,269 pipeline layout that we stored as well and that's that's really 1622 00:27:51,269 --> 00:27:51,279 stored as well and that's that's really 1623 00:27:51,279 --> 00:27:52,520 stored as well and that's that's really it right 1624 00:27:52,520 --> 00:27:52,530 it right 1625 00:27:52,530 --> 00:27:53,590 it right [Music] 1626 00:27:53,590 --> 00:27:53,600 [Music] 1627 00:27:53,600 --> 00:27:55,510 [Music] that's all there is to the destruction 1628 00:27:55,510 --> 00:27:55,520 that's all there is to the destruction 1629 00:27:55,520 --> 00:27:57,909 that's all there is to the destruction of a pipeline 1630 00:27:57,909 --> 00:27:57,919 of a pipeline 1631 00:27:57,919 --> 00:28:00,549 of a pipeline and then last but not least we have the 1632 00:28:00,549 --> 00:28:00,559 and then last but not least we have the 1633 00:28:00,559 --> 00:28:03,750 and then last but not least we have the pipeline bind which is just a simple one 1634 00:28:03,750 --> 00:28:03,760 pipeline bind which is just a simple one 1635 00:28:03,760 --> 00:28:06,470 pipeline bind which is just a simple one liner to vk command by bind pipeline 1636 00:28:06,470 --> 00:28:06,480 liner to vk command by bind pipeline 1637 00:28:06,480 --> 00:28:08,310 liner to vk command by bind pipeline right so this is called from within the 1638 00:28:08,310 --> 00:28:08,320 right so this is called from within the 1639 00:28:08,320 --> 00:28:10,630 right so this is called from within the context of a command buffer the bind 1640 00:28:10,630 --> 00:28:10,640 context of a command buffer the bind 1641 00:28:10,640 --> 00:28:12,789 context of a command buffer the bind point uh which we will get to when we 1642 00:28:12,789 --> 00:28:12,799 point uh which we will get to when we 1643 00:28:12,799 --> 00:28:14,870 point uh which we will get to when we actually set this up is passed through 1644 00:28:14,870 --> 00:28:14,880 actually set this up is passed through 1645 00:28:14,880 --> 00:28:17,190 actually set this up is passed through and then obviously the pipeline handle 1646 00:28:17,190 --> 00:28:17,200 and then obviously the pipeline handle 1647 00:28:17,200 --> 00:28:18,389 and then obviously the pipeline handle okay 1648 00:28:18,389 --> 00:28:18,399 okay 1649 00:28:18,399 --> 00:28:20,389 okay and so uh there's a lot of information 1650 00:28:20,389 --> 00:28:20,399 and so uh there's a lot of information 1651 00:28:20,399 --> 00:28:23,430 and so uh there's a lot of information here uh and unfortunately if i were to 1652 00:28:23,430 --> 00:28:23,440 here uh and unfortunately if i were to 1653 00:28:23,440 --> 00:28:25,430 here uh and unfortunately if i were to cover all of it 1654 00:28:25,430 --> 00:28:25,440 cover all of it 1655 00:28:25,440 --> 00:28:27,110 cover all of it we would be here for 1656 00:28:27,110 --> 00:28:27,120 we would be here for 1657 00:28:27,120 --> 00:28:28,630 we would be here for probably another hour 1658 00:28:28,630 --> 00:28:28,640 probably another hour 1659 00:28:28,640 --> 00:28:29,590 probably another hour so 1660 00:28:29,590 --> 00:28:29,600 so 1661 00:28:29,600 --> 00:28:31,350 so i would say this is a good opportunity 1662 00:28:31,350 --> 00:28:31,360 i would say this is a good opportunity 1663 00:28:31,360 --> 00:28:33,510 i would say this is a good opportunity to have a read through the spec on the 1664 00:28:33,510 --> 00:28:33,520 to have a read through the spec on the 1665 00:28:33,520 --> 00:28:35,669 to have a read through the spec on the vulcan pipeline and see what some of 1666 00:28:35,669 --> 00:28:35,679 vulcan pipeline and see what some of 1667 00:28:35,679 --> 00:28:37,750 vulcan pipeline and see what some of these properties in here 1668 00:28:37,750 --> 00:28:37,760 these properties in here 1669 00:28:37,760 --> 00:28:39,510 these properties in here do and become familiar with them because 1670 00:28:39,510 --> 00:28:39,520 do and become familiar with them because 1671 00:28:39,520 --> 00:28:40,710 do and become familiar with them because we're actually going to be coming back 1672 00:28:40,710 --> 00:28:40,720 we're actually going to be coming back 1673 00:28:40,720 --> 00:28:43,269 we're actually going to be coming back in here and changing some of this stuff 1674 00:28:43,269 --> 00:28:43,279 in here and changing some of this stuff 1675 00:28:43,279 --> 00:28:45,590 in here and changing some of this stuff and so be good a good idea for you guys 1676 00:28:45,590 --> 00:28:45,600 and so be good a good idea for you guys 1677 00:28:45,600 --> 00:28:47,830 and so be good a good idea for you guys to sort of you know get used to reading 1678 00:28:47,830 --> 00:28:47,840 to sort of you know get used to reading 1679 00:28:47,840 --> 00:28:49,990 to sort of you know get used to reading the documentation and and fully 1680 00:28:49,990 --> 00:28:50,000 the documentation and and fully 1681 00:28:50,000 --> 00:28:51,590 the documentation and and fully understanding 1682 00:28:51,590 --> 00:28:51,600 understanding 1683 00:28:51,600 --> 00:28:53,669 understanding everything that is is being said here 1684 00:28:53,669 --> 00:28:53,679 everything that is is being said here 1685 00:28:53,679 --> 00:28:55,669 everything that is is being said here okay 1686 00:28:55,669 --> 00:28:55,679 okay 1687 00:28:55,679 --> 00:29:00,470 okay all right so that is the pipeline 1688 00:29:00,470 --> 00:29:00,480 all right so that is the pipeline 1689 00:29:00,480 --> 00:29:01,909 all right so that is the pipeline so now that we 1690 00:29:01,909 --> 00:29:01,919 so now that we 1691 00:29:01,919 --> 00:29:02,710 so now that we have 1692 00:29:02,710 --> 00:29:02,720 have 1693 00:29:02,720 --> 00:29:04,549 have a interface here to actually create the 1694 00:29:04,549 --> 00:29:04,559 a interface here to actually create the 1695 00:29:04,559 --> 00:29:05,830 a interface here to actually create the pipeline 1696 00:29:05,830 --> 00:29:05,840 pipeline 1697 00:29:05,840 --> 00:29:07,669 pipeline let's go back to our shader 1698 00:29:07,669 --> 00:29:07,679 let's go back to our shader 1699 00:29:07,679 --> 00:29:09,110 let's go back to our shader and we'll actually start setting this 1700 00:29:09,110 --> 00:29:09,120 and we'll actually start setting this 1701 00:29:09,120 --> 00:29:10,230 and we'll actually start setting this stuff up 1702 00:29:10,230 --> 00:29:10,240 stuff up 1703 00:29:10,240 --> 00:29:12,389 stuff up okay so the first thing i'm going to do 1704 00:29:12,389 --> 00:29:12,399 okay so the first thing i'm going to do 1705 00:29:12,399 --> 00:29:14,230 okay so the first thing i'm going to do is put a to-do here for descriptors 1706 00:29:14,230 --> 00:29:14,240 is put a to-do here for descriptors 1707 00:29:14,240 --> 00:29:16,630 is put a to-do here for descriptors because we're not actually immediately 1708 00:29:16,630 --> 00:29:16,640 because we're not actually immediately 1709 00:29:16,640 --> 00:29:17,909 because we're not actually immediately going to use those although we are going 1710 00:29:17,909 --> 00:29:17,919 going to use those although we are going 1711 00:29:17,919 --> 00:29:19,909 going to use those although we are going to be using them very shortly uh we 1712 00:29:19,909 --> 00:29:19,919 to be using them very shortly uh we 1713 00:29:19,919 --> 00:29:21,909 to be using them very shortly uh we should not actually have to use those to 1714 00:29:21,909 --> 00:29:21,919 should not actually have to use those to 1715 00:29:21,919 --> 00:29:23,350 should not actually have to use those to get things up and running so i'm going 1716 00:29:23,350 --> 00:29:23,360 get things up and running so i'm going 1717 00:29:23,360 --> 00:29:25,590 get things up and running so i'm going to put it to do there 1718 00:29:25,590 --> 00:29:25,600 to put it to do there 1719 00:29:25,600 --> 00:29:26,710 to put it to do there and 1720 00:29:26,710 --> 00:29:26,720 and 1721 00:29:26,720 --> 00:29:28,630 and and skip those okay 1722 00:29:28,630 --> 00:29:28,640 and skip those okay 1723 00:29:28,640 --> 00:29:30,789 and skip those okay so now we're going to go ahead and 1724 00:29:30,789 --> 00:29:30,799 so now we're going to go ahead and 1725 00:29:30,799 --> 00:29:35,669 so now we're going to go ahead and proceed with pipeline generation so 1726 00:29:35,669 --> 00:29:35,679 1727 00:29:35,679 --> 00:29:36,710 the first thing we're going to want to 1728 00:29:36,710 --> 00:29:36,720 the first thing we're going to want to 1729 00:29:36,720 --> 00:29:40,070 the first thing we're going to want to define is the viewport so the viewport 1730 00:29:40,070 --> 00:29:40,080 define is the viewport so the viewport 1731 00:29:40,080 --> 00:29:43,830 define is the viewport so the viewport is basically going to be 1732 00:29:43,830 --> 00:29:43,840 1733 00:29:43,840 --> 00:29:44,630 x 1734 00:29:44,630 --> 00:29:44,640 x 1735 00:29:44,640 --> 00:29:45,750 x and y 1736 00:29:45,750 --> 00:29:45,760 and y 1737 00:29:45,760 --> 00:29:46,870 and y [Music] 1738 00:29:46,870 --> 00:29:46,880 [Music] 1739 00:29:46,880 --> 00:29:49,190 [Music] so x is going to be zero based y is 1740 00:29:49,190 --> 00:29:49,200 so x is going to be zero based y is 1741 00:29:49,200 --> 00:29:50,549 so x is going to be zero based y is going to be the height of the frame 1742 00:29:50,549 --> 00:29:50,559 going to be the height of the frame 1743 00:29:50,559 --> 00:29:51,909 going to be the height of the frame buffer 1744 00:29:51,909 --> 00:29:51,919 buffer 1745 00:29:51,919 --> 00:29:53,750 buffer the width is going to be as you would 1746 00:29:53,750 --> 00:29:53,760 the width is going to be as you would 1747 00:29:53,760 --> 00:29:55,190 the width is going to be as you would expect and then the height is actually 1748 00:29:55,190 --> 00:29:55,200 expect and then the height is actually 1749 00:29:55,200 --> 00:29:56,630 expect and then the height is actually going to be negative again because we're 1750 00:29:56,630 --> 00:29:56,640 going to be negative again because we're 1751 00:29:56,640 --> 00:29:58,549 going to be negative again because we're using 1752 00:29:58,549 --> 00:29:58,559 using 1753 00:29:58,559 --> 00:30:02,470 using the opengl equivalent way of doing this 1754 00:30:02,470 --> 00:30:02,480 the opengl equivalent way of doing this 1755 00:30:02,480 --> 00:30:03,830 the opengl equivalent way of doing this that's why we're starting at the bottom 1756 00:30:03,830 --> 00:30:03,840 that's why we're starting at the bottom 1757 00:30:03,840 --> 00:30:05,750 that's why we're starting at the bottom and going towards the top 1758 00:30:05,750 --> 00:30:05,760 and going towards the top 1759 00:30:05,760 --> 00:30:08,710 and going towards the top and then our depth we're clamping to min 1760 00:30:08,710 --> 00:30:08,720 and then our depth we're clamping to min 1761 00:30:08,720 --> 00:30:11,029 and then our depth we're clamping to min and max of zero and one perspective 1762 00:30:11,029 --> 00:30:11,039 and max of zero and one perspective 1763 00:30:11,039 --> 00:30:12,789 and max of zero and one perspective respectively 1764 00:30:12,789 --> 00:30:12,799 respectively 1765 00:30:12,799 --> 00:30:14,070 respectively our scissors basically going to be the 1766 00:30:14,070 --> 00:30:14,080 our scissors basically going to be the 1767 00:30:14,080 --> 00:30:15,909 our scissors basically going to be the size of the screen right it's going to 1768 00:30:15,909 --> 00:30:15,919 size of the screen right it's going to 1769 00:30:15,919 --> 00:30:19,350 size of the screen right it's going to clip anything that's outside of that 1770 00:30:19,350 --> 00:30:19,360 clip anything that's outside of that 1771 00:30:19,360 --> 00:30:21,430 clip anything that's outside of that now our attributes so our attributes are 1772 00:30:21,430 --> 00:30:21,440 now our attributes so our attributes are 1773 00:30:21,440 --> 00:30:23,909 now our attributes so our attributes are required we can't skip those so what i'm 1774 00:30:23,909 --> 00:30:23,919 required we can't skip those so what i'm 1775 00:30:23,919 --> 00:30:25,350 required we can't skip those so what i'm going to do is 1776 00:30:25,350 --> 00:30:25,360 going to do is 1777 00:30:25,360 --> 00:30:26,950 going to do is set up a 1778 00:30:26,950 --> 00:30:26,960 set up a 1779 00:30:26,960 --> 00:30:28,870 set up a structure that we can sort of 1780 00:30:28,870 --> 00:30:28,880 structure that we can sort of 1781 00:30:28,880 --> 00:30:30,870 structure that we can sort of expand as we go 1782 00:30:30,870 --> 00:30:30,880 expand as we go 1783 00:30:30,880 --> 00:30:33,190 expand as we go and so 1784 00:30:33,190 --> 00:30:33,200 and so 1785 00:30:33,200 --> 00:30:34,230 and so what we're going to do is we're going to 1786 00:30:34,230 --> 00:30:34,240 what we're going to do is we're going to 1787 00:30:34,240 --> 00:30:35,830 what we're going to do is we're going to track an offset that's going to be an 1788 00:30:35,830 --> 00:30:35,840 track an offset that's going to be an 1789 00:30:35,840 --> 00:30:37,669 track an offset that's going to be an offset size 1790 00:30:37,669 --> 00:30:37,679 offset size 1791 00:30:37,679 --> 00:30:39,430 offset size and we'll see where that comes into play 1792 00:30:39,430 --> 00:30:39,440 and we'll see where that comes into play 1793 00:30:39,440 --> 00:30:41,590 and we'll see where that comes into play here but basically as we add 1794 00:30:41,590 --> 00:30:41,600 here but basically as we add 1795 00:30:41,600 --> 00:30:43,350 here but basically as we add attributes we're going to be offsetting 1796 00:30:43,350 --> 00:30:43,360 attributes we're going to be offsetting 1797 00:30:43,360 --> 00:30:45,909 attributes we're going to be offsetting this and bytes 1798 00:30:45,909 --> 00:30:45,919 this and bytes 1799 00:30:45,919 --> 00:30:48,549 this and bytes and we'll go ahead and create 1800 00:30:48,549 --> 00:30:48,559 and we'll go ahead and create 1801 00:30:48,559 --> 00:30:50,950 and we'll go ahead and create an array here 1802 00:30:50,950 --> 00:30:50,960 an array here 1803 00:30:50,960 --> 00:30:53,510 an array here size of attribute descriptions and this 1804 00:30:53,510 --> 00:30:53,520 size of attribute descriptions and this 1805 00:30:53,520 --> 00:30:55,750 size of attribute descriptions and this is not using vlas because we are using a 1806 00:30:55,750 --> 00:30:55,760 is not using vlas because we are using a 1807 00:30:55,760 --> 00:30:57,669 is not using vlas because we are using a constant value here so just bear that in 1808 00:30:57,669 --> 00:30:57,679 constant value here so just bear that in 1809 00:30:57,679 --> 00:30:59,430 constant value here so just bear that in mind 1810 00:30:59,430 --> 00:30:59,440 mind 1811 00:30:59,440 --> 00:31:00,389 mind and then 1812 00:31:00,389 --> 00:31:00,399 and then 1813 00:31:00,399 --> 00:31:01,990 and then what we're going to do is we are going 1814 00:31:01,990 --> 00:31:02,000 what we're going to do is we are going 1815 00:31:02,000 --> 00:31:02,830 what we're going to do is we are going to 1816 00:31:02,830 --> 00:31:02,840 to 1817 00:31:02,840 --> 00:31:06,630 to define our actual 1818 00:31:06,630 --> 00:31:06,640 define our actual 1819 00:31:06,640 --> 00:31:09,830 define our actual layout of our 1820 00:31:09,830 --> 00:31:09,840 layout of our 1821 00:31:09,840 --> 00:31:11,590 layout of our attributes okay 1822 00:31:11,590 --> 00:31:11,600 attributes okay 1823 00:31:11,600 --> 00:31:13,350 attributes okay and so for right now 1824 00:31:13,350 --> 00:31:13,360 and so for right now 1825 00:31:13,360 --> 00:31:16,950 and so for right now the way that this works is we have a 1826 00:31:16,950 --> 00:31:16,960 the way that this works is we have a 1827 00:31:16,960 --> 00:31:18,789 the way that this works is we have a variable that we're going to call 1828 00:31:18,789 --> 00:31:18,799 variable that we're going to call 1829 00:31:18,799 --> 00:31:20,630 variable that we're going to call formats and this is going to be of 1830 00:31:20,630 --> 00:31:20,640 formats and this is going to be of 1831 00:31:20,640 --> 00:31:22,710 formats and this is going to be of attribute count size and this is going 1832 00:31:22,710 --> 00:31:22,720 attribute count size and this is going 1833 00:31:22,720 --> 00:31:24,310 attribute count size and this is going to give us the 1834 00:31:24,310 --> 00:31:24,320 to give us the 1835 00:31:24,320 --> 00:31:26,470 to give us the format of each attribute 1836 00:31:26,470 --> 00:31:26,480 format of each attribute 1837 00:31:26,480 --> 00:31:29,110 format of each attribute and our first first and right now only 1838 00:31:29,110 --> 00:31:29,120 and our first first and right now only 1839 00:31:29,120 --> 00:31:30,789 and our first first and right now only attribute if you recall 1840 00:31:30,789 --> 00:31:30,799 attribute if you recall 1841 00:31:30,799 --> 00:31:32,789 attribute if you recall is one of position which is a vector 1842 00:31:32,789 --> 00:31:32,799 is one of position which is a vector 1843 00:31:32,799 --> 00:31:33,750 is one of position which is a vector three 1844 00:31:33,750 --> 00:31:33,760 three 1845 00:31:33,760 --> 00:31:35,830 three so we are actually going to use the vk 1846 00:31:35,830 --> 00:31:35,840 so we are actually going to use the vk 1847 00:31:35,840 --> 00:31:40,950 so we are actually going to use the vk format r32 g32 b32 s float 1848 00:31:40,950 --> 00:31:40,960 format r32 g32 b32 s float 1849 00:31:40,960 --> 00:31:42,470 format r32 g32 b32 s float and so even though 1850 00:31:42,470 --> 00:31:42,480 and so even though 1851 00:31:42,480 --> 00:31:44,470 and so even though this is colors you can also use this as 1852 00:31:44,470 --> 00:31:44,480 this is colors you can also use this as 1853 00:31:44,480 --> 00:31:45,909 this is colors you can also use this as positions because it winds up being the 1854 00:31:45,909 --> 00:31:45,919 positions because it winds up being the 1855 00:31:45,919 --> 00:31:47,269 positions because it winds up being the same data 1856 00:31:47,269 --> 00:31:47,279 same data 1857 00:31:47,279 --> 00:31:48,389 same data basically what it's saying is we're 1858 00:31:48,389 --> 00:31:48,399 basically what it's saying is we're 1859 00:31:48,399 --> 00:31:50,070 basically what it's saying is we're using a 1860 00:31:50,070 --> 00:31:50,080 using a 1861 00:31:50,080 --> 00:31:55,669 using a 32 bit for r or x 32 bit for g or y 1862 00:31:55,669 --> 00:31:55,679 32 bit for r or x 32 bit for g or y 1863 00:31:55,679 --> 00:31:57,590 32 bit for r or x 32 bit for g or y 32 bits for 1864 00:31:57,590 --> 00:31:57,600 32 bits for 1865 00:31:57,600 --> 00:31:59,029 32 bits for b or z 1866 00:31:59,029 --> 00:31:59,039 b or z 1867 00:31:59,039 --> 00:32:00,870 b or z and then that they're going to be 1868 00:32:00,870 --> 00:32:00,880 and then that they're going to be 1869 00:32:00,880 --> 00:32:03,669 and then that they're going to be floating point right so this just tells 1870 00:32:03,669 --> 00:32:03,679 floating point right so this just tells 1871 00:32:03,679 --> 00:32:05,750 floating point right so this just tells um the pipeline that that's what we're 1872 00:32:05,750 --> 00:32:05,760 um the pipeline that that's what we're 1873 00:32:05,760 --> 00:32:07,110 um the pipeline that that's what we're going to be using 1874 00:32:07,110 --> 00:32:07,120 going to be using 1875 00:32:07,120 --> 00:32:09,110 going to be using okay and so every time we add an 1876 00:32:09,110 --> 00:32:09,120 okay and so every time we add an 1877 00:32:09,120 --> 00:32:11,669 okay and so every time we add an attribute we'll increment this and add 1878 00:32:11,669 --> 00:32:11,679 attribute we'll increment this and add 1879 00:32:11,679 --> 00:32:14,310 attribute we'll increment this and add its format here 1880 00:32:14,310 --> 00:32:14,320 its format here 1881 00:32:14,320 --> 00:32:17,509 its format here and then obviously we will need to track 1882 00:32:17,509 --> 00:32:17,519 and then obviously we will need to track 1883 00:32:17,519 --> 00:32:19,269 and then obviously we will need to track sizes as well 1884 00:32:19,269 --> 00:32:19,279 sizes as well 1885 00:32:19,279 --> 00:32:21,909 sizes as well so at least initially we only have one 1886 00:32:21,909 --> 00:32:21,919 so at least initially we only have one 1887 00:32:21,919 --> 00:32:23,029 so at least initially we only have one size 1888 00:32:23,029 --> 00:32:23,039 size 1889 00:32:23,039 --> 00:32:24,789 size because it's the you know obviously the 1890 00:32:24,789 --> 00:32:24,799 because it's the you know obviously the 1891 00:32:24,799 --> 00:32:26,389 because it's the you know obviously the size of attribute count and it's the 1892 00:32:26,389 --> 00:32:26,399 size of attribute count and it's the 1893 00:32:26,399 --> 00:32:28,310 size of attribute count and it's the size of vector 3 because position is a 1894 00:32:28,310 --> 00:32:28,320 size of vector 3 because position is a 1895 00:32:28,320 --> 00:32:29,830 size of vector 3 because position is a vector 3. 1896 00:32:29,830 --> 00:32:29,840 vector 3. 1897 00:32:29,840 --> 00:32:32,070 vector 3. and i believe that we actually do not 1898 00:32:32,070 --> 00:32:32,080 and i believe that we actually do not 1899 00:32:32,080 --> 00:32:36,710 and i believe that we actually do not have vector 3 here so i'll 1900 00:32:36,710 --> 00:32:36,720 1901 00:32:36,720 --> 00:32:40,800 i'll need to include math types up here 1902 00:32:40,800 --> 00:32:40,810 i'll need to include math types up here 1903 00:32:40,810 --> 00:32:43,029 i'll need to include math types up here [Music] 1904 00:32:43,029 --> 00:32:43,039 [Music] 1905 00:32:43,039 --> 00:32:44,230 [Music] math types 1906 00:32:44,230 --> 00:32:44,240 math types 1907 00:32:44,240 --> 00:32:45,990 math types okay 1908 00:32:45,990 --> 00:32:46,000 okay 1909 00:32:46,000 --> 00:32:48,470 okay and so we have an array of formats an 1910 00:32:48,470 --> 00:32:48,480 and so we have an array of formats an 1911 00:32:48,480 --> 00:32:51,590 and so we have an array of formats an array of sizes those things line up 1912 00:32:51,590 --> 00:32:51,600 array of sizes those things line up 1913 00:32:51,600 --> 00:32:54,789 array of sizes those things line up and so what we'll wind up doing 1914 00:32:54,789 --> 00:32:54,799 and so what we'll wind up doing 1915 00:32:54,799 --> 00:32:57,509 and so what we'll wind up doing is looping through both of those arrays 1916 00:32:57,509 --> 00:32:57,519 is looping through both of those arrays 1917 00:32:57,519 --> 00:32:59,590 is looping through both of those arrays and setting our attribute descriptions 1918 00:32:59,590 --> 00:32:59,600 and setting our attribute descriptions 1919 00:32:59,600 --> 00:33:01,190 and setting our attribute descriptions which is here 1920 00:33:01,190 --> 00:33:01,200 which is here 1921 00:33:01,200 --> 00:33:03,590 which is here in this array 1922 00:33:03,590 --> 00:33:03,600 in this array 1923 00:33:03,600 --> 00:33:06,549 in this array and we'll set the 1924 00:33:06,549 --> 00:33:06,559 and we'll set the 1925 00:33:06,559 --> 00:33:09,029 and we'll set the oops i need a semicolon there there we 1926 00:33:09,029 --> 00:33:09,039 oops i need a semicolon there there we 1927 00:33:09,039 --> 00:33:12,470 oops i need a semicolon there there we go and so we'll set the the binding 1928 00:33:12,470 --> 00:33:12,480 go and so we'll set the the binding 1929 00:33:12,480 --> 00:33:14,630 go and so we'll set the the binding index which is always going to be 1930 00:33:14,630 --> 00:33:14,640 index which is always going to be 1931 00:33:14,640 --> 00:33:16,710 index which is always going to be 0 in our case because we're not going to 1932 00:33:16,710 --> 00:33:16,720 0 in our case because we're not going to 1933 00:33:16,720 --> 00:33:19,110 0 in our case because we're not going to be using multiple bindings for this 1934 00:33:19,110 --> 00:33:19,120 be using multiple bindings for this 1935 00:33:19,120 --> 00:33:21,990 be using multiple bindings for this the location of it is going to be i so 1936 00:33:21,990 --> 00:33:22,000 the location of it is going to be i so 1937 00:33:22,000 --> 00:33:23,590 the location of it is going to be i so at least for the first one it'll be zero 1938 00:33:23,590 --> 00:33:23,600 at least for the first one it'll be zero 1939 00:33:23,600 --> 00:33:25,269 at least for the first one it'll be zero for the second one it'll be one et 1940 00:33:25,269 --> 00:33:25,279 for the second one it'll be one et 1941 00:33:25,279 --> 00:33:28,960 for the second one it'll be one et cetera so this location maps to 1942 00:33:28,960 --> 00:33:28,970 cetera so this location maps to 1943 00:33:28,970 --> 00:33:32,070 cetera so this location maps to [Music] 1944 00:33:32,070 --> 00:33:32,080 1945 00:33:32,080 --> 00:33:34,310 this location here okay so the first 1946 00:33:34,310 --> 00:33:34,320 this location here okay so the first 1947 00:33:34,320 --> 00:33:37,269 this location here okay so the first will always be position right 1948 00:33:37,269 --> 00:33:37,279 will always be position right 1949 00:33:37,279 --> 00:33:39,509 will always be position right and then uh we'll use the format at the 1950 00:33:39,509 --> 00:33:39,519 and then uh we'll use the format at the 1951 00:33:39,519 --> 00:33:41,830 and then uh we'll use the format at the given index and then we'll also use the 1952 00:33:41,830 --> 00:33:41,840 given index and then we'll also use the 1953 00:33:41,840 --> 00:33:43,669 given index and then we'll also use the offset which is going to be 1954 00:33:43,669 --> 00:33:43,679 offset which is going to be 1955 00:33:43,679 --> 00:33:45,750 offset which is going to be uh incremented by the size that we 1956 00:33:45,750 --> 00:33:45,760 uh incremented by the size that we 1957 00:33:45,760 --> 00:33:48,310 uh incremented by the size that we defined here right so the offset for the 1958 00:33:48,310 --> 00:33:48,320 defined here right so the offset for the 1959 00:33:48,320 --> 00:33:49,750 defined here right so the offset for the first one obviously will be zero and 1960 00:33:49,750 --> 00:33:49,760 first one obviously will be zero and 1961 00:33:49,760 --> 00:33:50,870 first one obviously will be zero and that'll be 1962 00:33:50,870 --> 00:33:50,880 that'll be 1963 00:33:50,880 --> 00:33:53,590 that'll be offset by the size of that index which 1964 00:33:53,590 --> 00:33:53,600 offset by the size of that index which 1965 00:33:53,600 --> 00:33:55,750 offset by the size of that index which the first one will be size of vector 3 1966 00:33:55,750 --> 00:33:55,760 the first one will be size of vector 3 1967 00:33:55,760 --> 00:33:57,750 the first one will be size of vector 3 which will wind up being 12. okay 1968 00:33:57,750 --> 00:33:57,760 which will wind up being 12. okay 1969 00:33:57,760 --> 00:33:59,190 which will wind up being 12. okay and so this 1970 00:33:59,190 --> 00:33:59,200 and so this 1971 00:33:59,200 --> 00:34:01,669 and so this is just a nice easy way for us to make 1972 00:34:01,669 --> 00:34:01,679 is just a nice easy way for us to make 1973 00:34:01,679 --> 00:34:03,590 is just a nice easy way for us to make this so that all we have to change 1974 00:34:03,590 --> 00:34:03,600 this so that all we have to change 1975 00:34:03,600 --> 00:34:04,710 this so that all we have to change is this 1976 00:34:04,710 --> 00:34:04,720 is this 1977 00:34:04,720 --> 00:34:07,830 is this and this as well as the overall count 1978 00:34:07,830 --> 00:34:07,840 and this as well as the overall count 1979 00:34:07,840 --> 00:34:09,909 and this as well as the overall count and we don't have to change any of our 1980 00:34:09,909 --> 00:34:09,919 and we don't have to change any of our 1981 00:34:09,919 --> 00:34:12,710 and we don't have to change any of our logic to support it going forward okay 1982 00:34:12,710 --> 00:34:12,720 logic to support it going forward okay 1983 00:34:12,720 --> 00:34:15,669 logic to support it going forward okay so it's kind of configurable kind of not 1984 00:34:15,669 --> 00:34:15,679 so it's kind of configurable kind of not 1985 00:34:15,679 --> 00:34:17,030 so it's kind of configurable kind of not we'll probably wind up making something 1986 00:34:17,030 --> 00:34:17,040 we'll probably wind up making something 1987 00:34:17,040 --> 00:34:19,430 we'll probably wind up making something a little bit more flexible than this in 1988 00:34:19,430 --> 00:34:19,440 a little bit more flexible than this in 1989 00:34:19,440 --> 00:34:21,829 a little bit more flexible than this in the future but for right now 1990 00:34:21,829 --> 00:34:21,839 the future but for right now 1991 00:34:21,839 --> 00:34:23,909 the future but for right now this will simplify things for us for the 1992 00:34:23,909 --> 00:34:23,919 this will simplify things for us for the 1993 00:34:23,919 --> 00:34:25,109 this will simplify things for us for the time being 1994 00:34:25,109 --> 00:34:25,119 time being 1995 00:34:25,119 --> 00:34:26,230 time being okay 1996 00:34:26,230 --> 00:34:26,240 okay 1997 00:34:26,240 --> 00:34:28,470 okay so the next thing that we need to do 1998 00:34:28,470 --> 00:34:28,480 so the next thing that we need to do 1999 00:34:28,480 --> 00:34:31,829 so the next thing that we need to do is we need to set up our stages 2000 00:34:31,829 --> 00:34:31,839 is we need to set up our stages 2001 00:34:31,839 --> 00:34:36,470 is we need to set up our stages and our stages 2002 00:34:36,470 --> 00:34:36,480 2003 00:34:36,480 --> 00:34:37,990 are just going to be pipeline shader 2004 00:34:37,990 --> 00:34:38,000 are just going to be pipeline shader 2005 00:34:38,000 --> 00:34:40,869 are just going to be pipeline shader stage create info right and in this case 2006 00:34:40,869 --> 00:34:40,879 stage create info right and in this case 2007 00:34:40,879 --> 00:34:42,950 stage create info right and in this case it's going to be 2 because our object 2008 00:34:42,950 --> 00:34:42,960 it's going to be 2 because our object 2009 00:34:42,960 --> 00:34:46,149 it's going to be 2 because our object shader stage count is 2. 2010 00:34:46,149 --> 00:34:46,159 shader stage count is 2. 2011 00:34:46,159 --> 00:34:47,909 shader stage count is 2. so to be safe we're just going to zero 2012 00:34:47,909 --> 00:34:47,919 so to be safe we're just going to zero 2013 00:34:47,919 --> 00:34:50,069 so to be safe we're just going to zero out that entire thing and then we're 2014 00:34:50,069 --> 00:34:50,079 out that entire thing and then we're 2015 00:34:50,079 --> 00:34:52,069 out that entire thing and then we're going to loop through each stage and 2016 00:34:52,069 --> 00:34:52,079 going to loop through each stage and 2017 00:34:52,079 --> 00:34:53,750 going to loop through each stage and copy over the s-type 2018 00:34:53,750 --> 00:34:53,760 copy over the s-type 2019 00:34:53,760 --> 00:34:56,950 copy over the s-type as well as the shader create info right 2020 00:34:56,950 --> 00:34:56,960 as well as the shader create info right 2021 00:34:56,960 --> 00:34:59,270 as well as the shader create info right and so that will fill this guy out to be 2022 00:34:59,270 --> 00:34:59,280 and so that will fill this guy out to be 2023 00:34:59,280 --> 00:35:00,470 and so that will fill this guy out to be used 2024 00:35:00,470 --> 00:35:00,480 used 2025 00:35:00,480 --> 00:35:03,270 used i also do want to point out that uh 2026 00:35:03,270 --> 00:35:03,280 i also do want to point out that uh 2027 00:35:03,280 --> 00:35:05,430 i also do want to point out that uh we're not doing descriptors yet 2028 00:35:05,430 --> 00:35:05,440 we're not doing descriptors yet 2029 00:35:05,440 --> 00:35:07,030 we're not doing descriptors yet but this is where that's going to wind 2030 00:35:07,030 --> 00:35:07,040 but this is where that's going to wind 2031 00:35:07,040 --> 00:35:08,550 but this is where that's going to wind up being so i'm going to put it to do 2032 00:35:08,550 --> 00:35:08,560 up being so i'm going to put it to do 2033 00:35:08,560 --> 00:35:10,230 up being so i'm going to put it to do here 2034 00:35:10,230 --> 00:35:10,240 here 2035 00:35:10,240 --> 00:35:12,550 here so that we come back to that 2036 00:35:12,550 --> 00:35:12,560 so that we come back to that 2037 00:35:12,560 --> 00:35:14,820 so that we come back to that when we actually start using descriptors 2038 00:35:14,820 --> 00:35:14,830 when we actually start using descriptors 2039 00:35:14,830 --> 00:35:17,190 when we actually start using descriptors [Music] 2040 00:35:17,190 --> 00:35:17,200 [Music] 2041 00:35:17,200 --> 00:35:19,349 [Music] and then we're going to go ahead and 2042 00:35:19,349 --> 00:35:19,359 and then we're going to go ahead and 2043 00:35:19,359 --> 00:35:22,230 and then we're going to go ahead and create the pipeline 2044 00:35:22,230 --> 00:35:22,240 create the pipeline 2045 00:35:22,240 --> 00:35:25,109 create the pipeline okay and obviously that's going to call 2046 00:35:25,109 --> 00:35:25,119 okay and obviously that's going to call 2047 00:35:25,119 --> 00:35:27,829 okay and obviously that's going to call we're going to call vulcan graphics 2048 00:35:27,829 --> 00:35:27,839 we're going to call vulcan graphics 2049 00:35:27,839 --> 00:35:30,950 we're going to call vulcan graphics pipeline create which means that we need 2050 00:35:30,950 --> 00:35:30,960 pipeline create which means that we need 2051 00:35:30,960 --> 00:35:33,030 pipeline create which means that we need to actually include that 2052 00:35:33,030 --> 00:35:33,040 to actually include that 2053 00:35:33,040 --> 00:35:34,390 to actually include that so right under 2054 00:35:34,390 --> 00:35:34,400 so right under 2055 00:35:34,400 --> 00:35:36,310 so right under

00:36:35,750 --> 00:36:35,760 to create our pipeline so what i'm going 2111 00:36:35,760 --> 00:36:37,990 to create our pipeline so what i'm going to do is i'm going to set a breakpoint 2112 00:36:37,990 --> 00:36:38,000 to do is i'm going to set a breakpoint 2113 00:36:38,000 --> 00:36:39,589 to do is i'm going to set a breakpoint here 2114 00:36:39,589 --> 00:36:39,599 here 2115 00:36:39,599 --> 00:36:41,270 here and i'm gonna go ahead and build 2116 00:36:41,270 --> 00:36:41,280 and i'm gonna go ahead and build 2117 00:36:41,280 --> 00:36:42,790 and i'm gonna go ahead and build and looks like we had a warning let me 2118 00:36:42,790 --> 00:36:42,800 and looks like we had a warning let me 2119 00:36:42,800 --> 00:36:44,069 and looks like we had a warning let me just 2120 00:36:44,069 --> 00:36:44,079 just 2121 00:36:44,079 --> 00:36:45,910 just verify this 2122 00:36:45,910 --> 00:36:45,920 verify this 2123 00:36:45,920 --> 00:36:48,069 verify this looks like we forgot to include k memory 2124 00:36:48,069 --> 00:36:48,079 looks like we forgot to include k memory 2125 00:36:48,079 --> 00:36:49,829 looks like we forgot to include k memory in our object shader i thought i already 2126 00:36:49,829 --> 00:36:49,839 in our object shader i thought i already 2127 00:36:49,839 --> 00:36:52,790 in our object shader i thought i already got that 2128 00:36:52,790 --> 00:36:52,800 2129 00:36:52,800 --> 00:36:54,710 nope i didn't okay 2130 00:36:54,710 --> 00:36:54,720 nope i didn't okay 2131 00:36:54,720 --> 00:36:57,349 nope i didn't okay so i'll include core 2132 00:36:57,349 --> 00:36:57,359 so i'll include core 2133 00:36:57,359 --> 00:36:58,630 so i'll include core okay memory 2134 00:36:58,630 --> 00:36:58,640 okay memory 2135 00:36:58,640 --> 00:37:00,550 okay memory build again 2136 00:37:00,550 --> 00:37:00,560 build again 2137 00:37:00,560 --> 00:37:02,310 build again and no errors okay 2138 00:37:02,310 --> 00:37:02,320 and no errors okay 2139 00:37:02,320 --> 00:37:05,910 and no errors okay so let's go ahead and run 2140 00:37:05,910 --> 00:37:05,920 2141 00:37:05,920 --> 00:37:07,910 and we'll go ahead and check our 2142 00:37:07,910 --> 00:37:07,920 and we'll go ahead and check our 2143 00:37:07,920 --> 00:37:11,030 and we'll go ahead and check our pipeline creation so i'm just going to 2144 00:37:11,030 --> 00:37:11,040 pipeline creation so i'm just going to 2145 00:37:11,040 --> 00:37:13,030 pipeline creation so i'm just going to actually skip over all this assignment 2146 00:37:13,030 --> 00:37:13,040 actually skip over all this assignment 2147 00:37:13,040 --> 00:37:14,150 actually skip over all this assignment here 2148 00:37:14,150 --> 00:37:14,160 here 2149 00:37:14,160 --> 00:37:16,150 here and come down here 2150 00:37:16,150 --> 00:37:16,160 and come down here 2151 00:37:16,160 --> 00:37:19,109 and come down here to our pipeline layout right 2152 00:37:19,109 --> 00:37:19,119 to our pipeline layout right 2153 00:37:19,119 --> 00:37:22,230 to our pipeline layout right so i will go ahead and run this okay and 2154 00:37:22,230 --> 00:37:22,240 so i will go ahead and run this okay and 2155 00:37:22,240 --> 00:37:24,710 so i will go ahead and run this okay and we didn't assert there so we're good 2156 00:37:24,710 --> 00:37:24,720 we didn't assert there so we're good 2157 00:37:24,720 --> 00:37:26,970 we didn't assert there so we're good and i'll skip over these things 2158 00:37:26,970 --> 00:37:26,980 and i'll skip over these things 2159 00:37:26,980 --> 00:37:28,069 and i'll skip over these things [Music] 2160 00:37:28,069 --> 00:37:28,079 [Music] 2161 00:37:28,079 --> 00:37:30,390 [Music] and here our 2162 00:37:30,390 --> 00:37:30,400 and here our 2163 00:37:30,400 --> 00:37:31,349 and here our result 2164 00:37:31,349 --> 00:37:31,359 result 2165 00:37:31,359 --> 00:37:34,310 result for our create pipelines 2166 00:37:34,310 --> 00:37:34,320 for our create pipelines 2167 00:37:34,320 --> 00:37:36,630 for our create pipelines we'll go ahead and 2168 00:37:36,630 --> 00:37:36,640 we'll go ahead and 2169 00:37:36,640 --> 00:37:38,470 we'll go ahead and skip over that 2170 00:37:38,470 --> 00:37:38,480 skip over that 2171 00:37:38,480 --> 00:37:40,950 skip over that our result is vk success so we have 2172 00:37:40,950 --> 00:37:40,960 our result is vk success so we have 2173 00:37:40,960 --> 00:37:43,349 our result is vk success so we have wired up everything as needed and we do 2174 00:37:43,349 --> 00:37:43,359 wired up everything as needed and we do 2175 00:37:43,359 --> 00:37:45,109 wired up everything as needed and we do not have any validation errors here so 2176 00:37:45,109 --> 00:37:45,119 not have any validation errors here so 2177 00:37:45,119 --> 00:37:47,990 not have any validation errors here so that's also a good sign 2178 00:37:47,990 --> 00:37:48,000 that's also a good sign 2179 00:37:48,000 --> 00:37:48,950 that's also a good sign and 2180 00:37:48,950 --> 00:37:48,960 and 2181 00:37:48,960 --> 00:37:50,950 and that means that our graphics pipeline is 2182 00:37:50,950 --> 00:37:50,960 that means that our graphics pipeline is 2183 00:37:50,960 --> 00:37:53,750 that means that our graphics pipeline is created and we're good to go so 2184 00:37:53,750 --> 00:37:53,760 created and we're good to go so 2185 00:37:53,760 --> 00:37:55,589 created and we're good to go so that means that we can go ahead and let 2186 00:37:55,589 --> 00:37:55,599 that means that we can go ahead and let 2187 00:37:55,599 --> 00:37:56,630 that means that we can go ahead and let this run 2188 00:37:56,630 --> 00:37:56,640 this run 2189 00:37:56,640 --> 00:37:59,589 this run and again we're not going to see 2190 00:37:59,589 --> 00:37:59,599 and again we're not going to see 2191 00:37:59,599 --> 00:38:03,670 and again we're not going to see sort of anything actually appearing 2192 00:38:03,670 --> 00:38:03,680 2193 00:38:03,680 --> 00:38:05,910 just yet on the screen but 2194 00:38:05,910 --> 00:38:05,920 just yet on the screen but 2195 00:38:05,920 --> 00:38:06,870 just yet on the screen but we are 2196 00:38:06,870 --> 00:38:06,880 we are 2197 00:38:06,880 --> 00:38:08,150 we are getting there 2198 00:38:08,150 --> 00:38:08,160 getting there 2199 00:38:08,160 --> 00:38:10,630 getting there uh however it looks like we have 2200 00:38:10,630 --> 00:38:10,640 uh however it looks like we have 2201 00:38:10,640 --> 00:38:13,349 uh however it looks like we have forgotten to destroy something so 2202 00:38:13,349 --> 00:38:13,359 forgotten to destroy something so 2203 00:38:13,359 --> 00:38:17,270 forgotten to destroy something so destroy device 2204 00:38:17,270 --> 00:38:17,280

go ahead and 2208 00:38:21,670 --> 00:38:21,680 pipeline destroy so let me go ahead and 2209 00:38:21,680 --> 00:38:22,700 pipeline destroy so let me go ahead and wire that up 2210 00:38:22,700 --> 00:38:22,710 wire that up 2211 00:38:22,710 --> 00:38:23,990 wire that up [Music] 2212 00:38:23,990 --> 00:38:24,000 [Music] 2213 00:38:24,000 --> 00:38:27,270 [Music] so that is going to be an object shader 2214 00:38:27,270 --> 00:38:27,280 so that is going to be an object shader 2215 00:38:27,280 --> 00:38:28,550 so that is going to be an object shader and then 2216 00:38:28,550 --> 00:38:28,560 and then 2217 00:38:28,560 --> 00:38:30,630 and then before we destroy the shader modules we 2218 00:38:30,630 --> 00:38:30,640 before we destroy the shader modules we 2219 00:38:30,640 --> 00:38:34,230 before we destroy the shader modules we are going to destroy this so we'll say 2220 00:38:34,230 --> 00:38:34,240 are going to destroy this so we'll say 2221 00:38:34,240 --> 00:38:36,710 are going to destroy this so we'll say context 2222 00:38:36,710 --> 00:38:36,720 context 2223 00:38:36,720 --> 00:38:38,069 context and 2224 00:38:38,069 --> 00:38:38,079 and 2225 00:38:38,079 -->
