ProgramA better Bi-Directional Path Tracer

So I’m back to working on this again.. It’s a lot better than before but it’s not perfect. I’m still using unweighted samples during path generation and I am still generating a fresh path (highly randomized in path traced -> light traced construction) for every sample. Because of this the noise that still persists in the image above will never feasibly go away. Today I plan to look at “Multiple Importance Sampling” a lot more in depth.
