Show HN: a Rust ray tracer that runs on any GPU – even in the browser

I’ve been experimenting with Rust lately and wanted a project that would help me explore some of its lower-level and performance-oriented features. Inspired by Sebastian Lague’s videos, I decided to implement my own ray tracer from scratch.

The initial goal was just to render a simple 3D scene in the browser at a reasonable frame rate. It evolved into a small renderer that can: • Run locally or on the web using wgpu and WebAssembly • Perform mesh rendering with a Bounding Volume Hierarchy (BVH) for acceleration • Simulate both direct and indirect illumination for photorealistic results • Be deployed easily as a free web demo using GitHub Pages

The project is far from perfect, but it’s been a fun way to dig deeper into graphics programming and learn more about Rust’s ecosystem. I’m also planning to experiment with Rust for some ML projects next.

Would love feedback from anyone who’s built similar projects or has experience with wgpu or ray tracing in Rust.

It does not run: "unreachable executed"

Maybe your browser do not support webgpu. Try using Chrome.

Dosent work in firefox, because of missing webgpu.

Very cool. Enjoyed playing with the "bounces" slider - it's fascinating how little improvement each additional bounce contributes after about 3 bounces. Severely diminishing returns in terms of the final image quality.
