Simple path tracing project in Rust.
I also have a ray tracer and I intend to explore the difference between both techniques.
Scenes are TOML files (see scenes/) with render settings, tone mapping,
camera, environment, named materials and shapes:
cargo run --release -- render scenes/cornell.toml # CPU
cargo run --release -- render scenes/outdoor.toml --gpu # GPU
cargo run --release -- render scenes/cornell.toml --gpu --spp 100 --width 400 --height 300
cargo run --release -- view scenes/outdoor.toml # interactive GPU viewer
Renders land in output/. The examples/ directory has the same scenes
built in Rust; run one with cargo run --release --example cornell -- --gpu.
Features: CPU and GPU (wgpu compute) path tracing; spheres and discs; Lambertian, metal (GGX), dielectric, emissive and principled (metallic/roughness/transmission) materials with checker and bitmap textures; area lights with next event estimation and multiple importance sampling; constant, HDR image and Preetham procedural skies plus a sun; a Sobol sampler; thin-lens depth of field; exposure, tone mapping and bloom; an optional firefly clamp.
