PhotonForge RT is a lightweight real-time renderer written in Rust with wgpu.
It demonstrates progressive path tracing in compute shaders (WGSL), supporting diffuse, mirror, and glass materials,
with live performance metrics in the window title.
-
Progressive path tracing in WGSL compute
-
Materials: diffuse, perfect mirror, dielectric (glass/refraction via Schlick + Snell)
-
Lighting: point light with hard shadows + sky gradient
-
Progressive accumulation (reduces noise over frames)
-
Controls:
- WASD + QE for movement
- Mouse drag to rotate camera
-
HUD: window title shows FPS + per-pass timings (CPU-measured)
Example run: 16 SPP, 4 bounces, ~125 FPS
