Path Tracer
Physically-based renderer with Monte Carlo path tracing, supporting mirror, refraction, glossy BRDFs and global illumination.
A physically-based renderer built from scratch in C++ for Brown CS 224 (Computer Graphics). Implements the path tracing algorithm to solve the rendering equation via Monte Carlo sampling.
Features:
- Four BRDFs: diffuse, glossy specular, perfect mirror, dielectric refraction with Fresnel
- Soft shadows from area light source sampling
- Global illumination with color bleeding and caustics
- Event splitting for direct vs. indirect lighting
- Russian roulette path termination
- Extended Reinhard tone mapping
- BVH acceleration structure for fast ray-scene intersection
