CS 6620 - Fall 2019 - 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 with multiple bounces.
Render one or more scenes with indirect illumination, soft shadows and glossy surfaces.
Compare rendered images with different numbers of bounces.
Make sure to use gamma correction.

Optional Feature Suggestions

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