 usecallback | But I think this is not helping at all 🤣 | 07:03:02 |
| usecallback | The error seems to originate from glow | 07:03:46 |
 ryan | If I want to make my own wgsl preprocessor, is there something that can help me with that? Maybe parsing the code so I can find/rename functions easily? | 07:23:42 |

If I want to make my own wgsl preprocessor, is there something that can help me with that? Maybe parsing the code so I can find/rename functions easily? There's a crate called naga_oil that you might be able to draw some inspiration from, it has wgsl preprocessing. https://github.com/robtfm/naga_oil | 11:50:16 |

| norlock | In compute shaders is there a rule when ping pong buffers are faster then just write back to read_write storage? I get that for rendering ping pong is much faster, but in multiple compute shaders does it help to always ping pong instead of just the last one? | 21:20:18 |
 kvark | I don’t think it helps in compute ever | 21:38:25 |
 cwfitzgerald (wgpu, rend3) | Yeah if you can write back to the same place, might as well | 21:39:04 |
| cwfitzgerald (wgpu, rend3) | Ping pong is useful when you can't | 21:39:21 |
| norlock | Ah ok I will do that, thanks. | 21:42:11 |

| Dinnerbone | Are resources refcounted internally; when I make a Buffer and a BindGroup that uses that Buffer, when I drop the Buffer is the Bind Group still valid to use? | 15:56:05 |
| cwfitzgerald (wgpu, rend3) | Correct | 15:56:22 |
| cwfitzgerald (wgpu, rend3) | * Yes - they are | 15:56:31 |
| Dinnerbone | Awesome, so it's not truly destroyed until the bind group is also destroyed | 15:56:46 |
| Dinnerbone | Thaks! | 15:56:55 |
| Dinnerbone | * Thanks! | 15:56:59 |
| cwfitzgerald (wgpu, rend3) | Specifically it won't be destroyed until the maintain call (submit or poll) after the gpu is finished with it | 15:58:52 |
