Trace the Ray – Part 8 (Project: Bidirectional Path Tracing)

Hello trace-masters!

In this post, I will first give some information on indirect illumination in ray tracing and bidirectional path tracing algorithm, and then I will write about how I have implemented my term project, a naive version of the Bidirectional Path Tracing (BDPT) algorithm. Moreover, I will provide a comparison of my BDPT outputs with my ray tracer and path tracer outputs.
