Quick path tracer project written in C++
Features
- Lambert brdf for diffuse
- Cook-Torrance microfacet brdf for specular
- Uses OpenMP for multithreading
- Single-bounce atmospheric scattering model based on Elek
- Firefly reduction by limiting the roughness as the path bounces around
- Improved importance sampling for microfacet brdf
- Anti-aliasing
- Depth of field
