Features:

• Basic Path tracer (Part 1) implemented completely; specular reflection, diffusion, first bounce caching, stream compaction, material-based sort (using radix sort)
• Refraction with fresnel approximation.
• Stochastic Antialiasing
• Physically-based depth-of-field (buggy implementation, partially works)
• OBJ loading (complete), mesh collision + bounding boxes (partial)

Feedback: this project was a lot of work, even more than I expected (especially debugging) and I couldn't finish debugging two of the features in time (I'm also still waiting for generation of visuals). That being said, it was also a lot of fun (so I'll be finishing the incomplete parts later on regardless).
Earlier on, I also spent some time refactoring the starter helper files to be more stylistically consistent (I think there's also a minor memory leak in glslUtility; the manually allocated arrays of loadFile are never freed).
