Show HN: A physically-based GPU ray tracer written in Julia

https://makie.org/website/blogposts/raytracing/
7•simondanisch•1h ago
We ported pbrt-v4 to Julia and built it into a Makie backend. Any Makie plot can now be rendered with physically-based path tracing.

Julia compiles user-defined physics directly into GPU kernels, so anyone can extend the ray tracer with new materials and media - a black hole with gravitational lensing is ~200 lines of Julia.

Runs on AMD, NVIDIA, and CPU via KernelAbstractions.jl, with Metal coming soon.

On iOS Safari the videos are fullscreening themselves as I scroll. I've seen this on other blogs before but I don't know what causes it. Super annoying
