 ryan | hmm. I forced it to the latest naga, it's better but now I get textureSize(usampler2DArray) even though I'm using a textureDimensions(texture_2d_array<f32>) | 21:53:50 |

 maxammann | Is copyExternalImageToTexture already supported in wgpu? I did not find references to this API in the API docs or the Github | 11:15:14 |
 felixfaire | i asked this recently and i don't believe it is yet, we may have to wait for it's implementation in Firefox (afaik) | 11:32:26 |

| robtfm | hello, i'm looking at doing occlusion queries but it looks like wgpu doesn't expose them. have i missed it, or should i maybe just use pipeline statistics queries with fragment counts? | 13:23:10 |

i asked this recently and i don't believe it is yet, we may have to wait for it's implementation in Firefox (afaik) maxammann: fwiw, if someone wants to add this it's totally fine, it's wasm only anyway, one of us likely won't bother until ff supports it, so if you need it, it shouldn't be that hard to add | 14:01:00 |
| felixfaire | that's fair enough, i was wondering how a wasm only interface would work alongside the rest of the native apis. are there other examples of this? also it would be great to know what the webgl2 equivalent might be (if at all) | 14:23:49 |

| cwfitzgerald (wgpu, rend3) | I didn't think about webgl2, we would probably just need to pass through the copyFromExternalTexture all the way to the hal, and then throw that into texImage*D's HTMLCanvasElement/IMageBitmap overload | 15:33:18 |
| cwfitzgerald (wgpu, rend3) | shouldn't be that difficult to implement either | 15:33:31 |
| cwfitzgerald (wgpu, rend3) | texImage*D supports more everything copyExternalTextureToTexture does except offscreen canvases | 15:34:29 |

| cwfitzgerald (wgpu, rend3) | we don't support occlusion queries yet | 16:52:45 |
| cwfitzgerald (wgpu, rend3) | just not implemented, most of the infra should be there though | 16:52:53 |
| robtfm | thanks, i'll try with frag counts for now. i had a look through the pipeline statistics code and it does look like occlusion queries would be very similar so i might try to add | 18:11:34 |
