Show HN: A physically-based GPU ray tracer written in Julia
Operating in show hn launch, A physically-based GPU ray tracer written in Julia operates.
Profile
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.Demo scenes: github.com/SimonDanisch/RayDemo
A physically-based GPU ray tracer written in Julia is positioned in show hn launch, a segment that rewards a clear, focused offering.
Directory data places it at the Show HN launch stage.
