In this case wgpu is just providing the surface texture for the window that the software rendered pixels are drawn into.

I think it would be interesting, especially for dynamic use cases where you can recompile the graph but use it many times. Although it's also probably pretty niche to get to that l…

I think most non-trivial cross-platform graphics applications eventually end up with some kind of hardware abstraction layer. The interesting part is comparing how wgpu performs vs…

wgpu can run the WebGPU Conformance Test Suite for validation against the WebGPU specification. Was there something else you'd like to see?

Really excited to see WebGPU/wgpu ship in Firefox! Congratulations and thanks to Mozilla for supporting this.

Slug is patented but there are other similar approaches being worked on (e.g., vello https://news.ycombinator.com/item?id=44236423 that uses wgpu). I also created glyphon ( https:/…

Yes b'y, Newfoundland English is best kind sure.

wgpu has some options to access backend-specific types and shader passthrough (i.e., you provide your own shader for a backend directly). Generally wgpu is open to supporting any M…

wgpu has its own Metal backend that most people use by default (not MoltenVK). There is also a Vulkan backend if you want to run Vulkan through MoltenVK though.

Scaffolding wasn’t a problem at all. Both used SPIRV-Cross for shader conversions at the time and focused on implementing the rest of the API. The shading language barely matters t…

SPIR-V was never in the specification, but both wgpu and Dawn used SPIR-V in the meantime until a shading language decision was made.

I don't think that's accurate. Creating a shading language is obviously a huge effort, but there were already years of effort put into WebGPU as well as implementations/games build…

There's plenty of room for both approaches: a lot of projects can benefit from using a platform-agnostic API like WebGPU (web or native) directly, others might want to use engines.…

Multi-threading would be really nice, although it's not clear to me how to parallelize this in a way where the synchronization cost wouldn't regress performance. Tasks are prioriti…

Do you mean time was used as the key for the hashmap? What was the vector used for in that setup?

All great points, thank you! I'll need to think about this some more. For context, queries are trying to find the next available equipment for tens of thousands of tasks, so hundre…

Thanks for the reference! This looks like an implementation of a disjoint set/union-find data structure. I think it could be an interesting direction to explore by adapting union-f…

Thank you! I should have clarified that my map does currently store free time slots instead of booked time slots, but either representation would be ok if it would be beneficial fo…

Sounds interesting, I’ll check it out, thanks! Skimming through it quickly it seems like it may be focused on actual running timers instead of tracking intervals, but some of the i…

Thank you, I should look into these more. I actually came across them earlier but it wasn’t obvious that these would outperform a plain sorted `Vec` with binary search, which seeme…
