Description
When drawing meshes with a 0..0 instance range, ogpu crashes due to metal validation layers emitting an error. From my understanding on the WebGPU spec, this should be allowed and indeed works correctly on Vulkan and DX12.
Error
-[MTLDebugRenderCommandEncoder validateCommonDrawErrors:instanceCount:baseInstance:maxVertexID:]:5161: failed assertion `Draw Errors Valida
Paddle.js is a web project for Baidu PaddlePaddle, which is an open source deep learning framework running in the browser. Paddle.js can either load a pre-trained model, or transforming a model from paddle-hub with model transforming tools provided by Paddle.js. It could run in every browser with WebGL/WebGPU/WebAssembly supported. It could also run in Baidu Smartprogram and WX miniprogram.
Right now the compute rasterizer only supports a simple list of triangles. It would be a good exercise to add support for an index buffer to support more complex models without using too much memory. You'll need to:
Create another buffer, similar to the vertex buffer, that holds indices into the vertex buffer, and send that to the compute shader
