Rays

A Monte-Carlo Path Tracer in Rust. Features include:

• GGX microfacet material model for diffuse reflections and refractions.
• Importance sampling of rays for faster convergence.
• BVH object hierarchy for faster intersection lookup.
• Scene loader for .obj and .mat files.
• Optional integrated profiling and statistics counting.

Example renders can be found inside assets:
