CS 6620 - Fall 2014 - Ray Tracing for Graphics

Project 12 - Path Tracer

Unline the previous projects, in this project we will not simply add a new feature to our ray tracers. Instead, we will replace the Monte Carlo GI component with path tracing.

Requirements

Implement path tracing.
Render one or more scenes with indirect illumination, soft shadows and glossy surfaces.
Gamma correction.

Optional Feature Suggestions

Use importance sampling.
Implement Light tracing.
Implement Bidirectional path tracing.
