Day 1

Wishlist:

1. Fix the CUDA code for Augmented photon mapping (Diffraction code).
Currently the code performs uniform, regular sampling of the diffracting surface. Adding some randomness should improve things on the aliasing front.

2. Port the code to C++ (the last test on cpu was on matlab, which doesnt really count towards efficient processing). Learn how to use OpenMP and go all out on the dual socket opteron.

3. Read Tim Purcell's Raytracing on Stream Processors PhD thesis. This is a slightly longer term plan (ie: over 3 to 4 days)
