SORT, short for Simple Open-source Ray Tracing, is my personal cross platform ray tracing renderer. It is a standalone ray tracing program, while works well in Blender as a renderer plugin. Simliar to other open source ray tracer, like PBRT, luxrenderer, SORT is also a physically based renderer. However, since it is a solo project that I worked on in my spare time, it is way simpler comparing with its peers.
Here are the features implemented so far:
- Integrator. (Whitted ray tracing, direct lighting, path tracing, light tracing, bidirectional path tracing, instant radiosity, ambient occlusion)
- Spatial acceleration structure. (KD-Tree, BVH, Uniform grid, OcTree)
- Sampler. (Regular, random, stratified)
- BXDF. (Lambert, Oran Nayar, MicroFacet, MERL)
- Node graph based material system.
- Camera. (DOF)
- Multi-thread rendering.
- Blender plugin.
