It seems that some APIs missing.

wgpuRenderBundleEncoderEnd
wgpuRenderBundleEncoderDestroy

It seems there's never wgpuRenderBundleEncoderEnd.
And the wgpuRenderBundleEncoderDestroy should be wgpuRenderBundleEncoderRelease.

This probably comes from the fact that lib_webgpu_dawn.cpp has not been maintained in a while. It was originally contributed in a PR to enable expanding this repository to also target the native Dawn API, in addition to targeting web browsers WebGPU support.

But unfortunately lib_webgpu_dawn.cpp has fallen out of date, since it is not actively being tested or maintained. I pushed a commit 74466ad now to more properly reflect this fact.

OK. I see. I thought that the lib_webgpu_dawn.cpp is maintained by Unity Engine. I saw Brenden from Unity Global comitted to make it compatible with Unity Engine.

I'm at Unity China. Previously I have some chats with Brenden as well.

Yeah, that's correct. The file lib_webgpu_dawn.cpp was developed by Brendan, although the development has not been continuous to keep that file up to date.

If lib_webgpu_dawn.cpp was updated to the latest, would that help your use case? In the other ticket you mentioned "I have to wrap wasm_webgpu with standard webgpu.h to make my implementation compatible with Unity Engine". Does that mean you are using TuanJie's Unity to target Dawn natively for e.g. a Windows/Linux build?

I have been working towards getting a regular CI test suite running on this repository.. maybe the next project after that might be to update lib_webgpu_dawn.cpp to latest, if that would solve your challenges?

It does help. Anyway, I have modified it to use webgpu.h only. I'll test it if it works for me. I'm not using TuanJie's Unity to target Dawn natively.

In China, mini-game is popular. Some mini-game app company are asking about the possibility of WebGPU performance improvement. But Tuanjie from Unity China prefer Metal or Vulkan instruction buffer system instead. It uses GfxDeviceMetal or GfxDeviceVulkan directly to compose the instruction buffer and send it to the app natively. The app will render the mini-game using Metal or Vulkan directly.

But personally, I love the idea of WebGPU. It's cross platform. And most importantly, mini-app company are insterested in it.

So I implemented the mechanism like High Performance Plus and EmscriptenGLX to work with WebGPU personally to evaluate the performance. But the mecahnism I implementing is based on the emdawnwebgpu. But Unity is using wasm_webgpu instead. So I have to make wasm_webgpu wrap emdawnemscripten. Currently, only Unity 6 is with WebGPU support. So I'll evaluate it with Unity 6.

These are the scenarios that I want to check.
WebGL + High Performance Plus + EmscriptenGLX
Tuanjie + Metal instruction buffer system
WebGPU + modified emdawnwebgpu( similar to High Performance Plus + EmscriptenGLX) with wasm_webgpu wrapper

Here's the idea of High Performance Plus and EmscriptenGLX. Just use Google to translate it. They're only in Chinese.
