WebGPU Compute Rasterizer

This is a basic implementation of a rasterizer running on WebGPU compute shaders. It currently supports loading a list of triangles from a (very basic) glTF model and rendering it, with shading based on each triangle's distance to the camera.

I built this to create a simple template for exploring compute-based rendering techniques. Initially inspired by Rendering Point Clouds with Compute Shaders and Vertex Order Optimization.

See:

• How to Build a Compute Rasterizer with WebGPU for a step by step guide on building your own version of this.
• Or Code Overview for a brief walkthrough of the code & implementation.

Building locally

Run npm install and npm run dev. Then open localhost:3000.

You must use a browser that supports WebGPU. See the setup instructions in this article.
