rayray
A tiny GPU raytracer!
(more details on the project homepage)
Features
- Diffuse, metal, and glass materials
- The only three shapes that matter:
- Spheres
- Planes (both infinite and finite)
- Cylinders (both infinite and capped)
- Any shape can be a light!
- Antialiasing with sub-pixel sampling
- Will crash your entire computer if you render too many rays per frame (thanks, GPU drivers)
Implementation
- Built on the bones of Futureproof
- Written in Zig
- Using WebGPU for graphics
via
wgpu-native - Shaders compiled from GLSL to SPIR-V with
shaderc - Minimal GUI using Dear ImGUI, with a custom Zig + WebGPU backend
- Vaguely based on Ray Tracing in One Weekend, with a data-driven design to run on the GPU.
Project status
This is a personal / toy project,
and I don’t plan to support it on anything other than my laptop
(macOS 10.13, zig-macos-x86_64-0.8.0-dev.1125,
and wgpu-native built from source).
I’m unlikely to fix any issues, although I will optimistically merge small-to-medium PRs that fix bugs or add support for more platforms.
That being said, I’m generally friendly, so feel free to open issues and ask questions; just don’t set your expectations too high!
If you’d like to add major features, please fork the project; I’d be happy to link to any forks which achieve critical momemtum!
