 kvark | Ralith: do you have a topic in mind, to speak at the rust graphics conf? | 22:29:23 |
| kvark | cwfitzgerald: I'd love to hear about rend3 there. Architecture, history, results, anything. | 22:30:04 |
 Ralith | it'd be fun to properly share my work on rendering/physics of 1:1 scale planets, though I don't know if I'll have the energy to put together a proper talk in the near future | 23:46:57 |
| Ralith | also not at all wgpu/gfx based | 23:47:08 |

| kvark | Great | 01:04:47 |
| kvark | We'll make sure to be clear about this | 01:05:14 |

| tanriol | Hello :-) are there some reasonable ways (gfx-portability?) to run Vulkan-only software on top of OpenGL? | 19:59:02 |
| tanriol | Sorry if this is offtopic, but this room is my current best guess for a place where people know the state of the graphics world... | 19:59:56 |
| tanriol | * Hello :-) are there some reasonable ways (gfx-portability?) to run Vulkan-only software on top of OpenGL? | 20:00:05 |
 cwfitzgerald | In theory gfx-portability could do it, but in practice you can't run vulkan applications on top of GL | 20:27:01 |

| cwfitzgerald | And gfx-portability'a GL Backend is very broken in practice | 20:27:47 |

| kvark | There was another non-rust project doing that | 01:55:07 |
| cwfitzgerald | Do you remember the name? | 01:57:04 |
| kvark | Khronos had a table in one of the portability presentations... I don't recall the name, sorry | 02:18:07 |
| cwfitzgerald | "Ashes" | 02:23:09 |
| tanriol | Thank you for the reference, I'll look into it :-) | 10:15:44 |
| tanriol | I definitely don't expect close to native perf, but it's the only way I see to try running a Vulkan app on Nouveau, which for my laptop can reclock to max, but does not have Vulkan. Well, short of implementing that myself :-) | 10:19:09 |

 acowley | I have a wgpu program using the vulkan backend that reads the result of a render pass in a compute pass, and I'm getting nondeterministic amounts of the render pass output successfully read into the compute pass. My primary guess is that it's a bug in my code, but I've not been able to track it down yet. Is there somewhere in gfx (or elsewhere!) I could insert a pipeline barrier to rule out a barrier issue? | 18:11:27 |
| kvark | wgpu does this automatically. Perhaps you found a bug. Please file it, and attach an api trace | 18:31:24 |
| acowley | The program is rather large for a test case. I can try to find the barrier code myself, and I'll switch over to extracting a reproducer if it's taking too long. | 18:33:50 |
| kvark | I mean https://github.com/gfx-rs/wgpu/wiki/Debugging-wgpu-Applications#tracing-infrastructure | 18:49:32 |
| kvark | is it hard to reproduce within the program? | 18:49:41 |
