WebGPU Triangle sample using C# and Dawn

Hello WebGPU.Net

This an example of how to use WebGPU on .Net (Windows and Browser), leveraging the WaveEngine WebGPU bindings.

Check https://webgpu.z28.web.core.windows.net/ for a live preview.

WebGPU on the browser is only currently supported on Chrome/Edge Canary versions, and Firefox Nightly.

• Firefox: about:config -> dom.webgpu.enabled: true
• Chrome/Edge: chrome://flags/#enable-unsafe-webgpu -> "Enabled"

Run it locally

Set-Up environment

Right now compilation must be finished on linux. Follow the dotnet-setup.sh script to install necessary dependencies (tested on Ubuntu 18 LTS).

Compile & Link

First, compile the project with MSBuild, then go to Linux if you are on windows (Ubuntu 18 LTS - WSL1) and run package.sh with the specific arguments of your project:

./package.sh [PATH_TO_PROJECT]/HelloWebGPUNet/HelloWebGPUNet.Web/bin/Release/netstandard2.0 $HOME/.build HelloWebGPUNet.Web.dll -a

-a option builds the project on AOT mode (the only one supported for now due to a bug in mono). Check the full list of arguments at package.sh

After compilation and linking are successfull, serve the folder bin/$(Configuration)/wasm with a static server.

libWebGPU.o

TODO

hellowebgpu.net's Issues

Where is libwebgpu.o come from?

I have problem build project as blazor webassembly.
I use NativeFileReference in ItemGroup to link libwebgpu.o. (https://learn.microsoft.com/zh-cn/aspnet/core/blazor/webassembly-native-dependencies?view=aspnetcore-7.0)
But when I build the project, it show lots of undefined symbol. One of these:
undefined symbol: emscripten_webgpu_get_device (referenced by top-level compiled C/C++ code)

If I add EmccExtraLDFlags>-s WARN_ON_UNDEFINED_SYMBOLS=0</EmccExtraLDFlags> to PropertyGroup.
It can build successful but run failed that web console show blazor.webassembly.js:1 missing function: emscripten_webgpu_get_device.
I don't know how to solve it.
