As of wgpu-rs 0.13.1, on the rust side neither of these properties are currently visible to application code. Also the wgpu::Buffer type doesn't appear to be cachi
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
