Rust Ray Tracing Renderer: CPU, GPU, and Real-Time WebGPU Implementations
By

Kettled twice. Extra chewy, extra trustworthy.
Summary
This article describes a Rust-based ray tracing renderer project that demonstrates three different implementation approaches: a CPU-based path tracer, a GPU-accelerated offline renderer using compute shaders, and a real-time interactive WebGPU implementation. The project includes a live demo accessible online and provides instructions for local setup, allowing users to interact with the renderer using mouse controls and keyboard shortcuts to toggle between rendering modes.
