In this project, I have implemented a CUDA-based path tracer capable of rendering globally-illuminated images very quickly. Path tracing is a type of ray tracing which takes a random sampling of all of the rays to create the final image. This results in sampling a variety of different types of lighting, but especially global illumination.

Features Implemented in this Path Tracer:

• Ray sorting by material type

• First Bounce Cache

• Stream Compaction to remove terminated rays.

• Diffuse, reflective and refractive surfaces

• Stochastic Sampled Anti-Aliasing

• Depth of field using Bokeh effect

• Motion Blur

• Direct Lighting

• OBJ Mesh loading with Bounding Volume Intersection Culling

• Denoiser
