Path-Tracing project for a Computer Graphics class.
- Path tracing:
- Path is extended randomly at each intersection based on the BRDF.
- At each path vertex, a light is randomly sampled and its contribution is weighted using MIS.
- Spectral path-tracing, mainly using the techniques from PBRTv4.
- Scenes are loaded using PBRTv4's format
- Many shapes, texture types etc are not supported
- Ray-tracing using Intel's Embree library.
- Support for multiple shapes: triangles and spheres.
- A few BxDFs are implemented:
- Diffuse BRDF
- Smooth and rough conductor (metal) BRDFs
- Smooth dielectric BSDF
- Smooth and rough plastic BRDFs
- Simple analytic 2-layer material
- Support for bitmap textures.
- Environment map lighting with importance sampling.
- The renders are saved in HDR using the EXR file format.
