Implicit Direct Lighting (One bounce Path Tracing)

Here are my images showing implicit direct lighting. Because I had most of
the underlying code from last semester (CS 6650), I just had to tweak a few
things such as allowing only one bounce per ray. For now these are the images
I have generated, I will put some picts with more samples as soon as they finish
running!


Image 1: 16 samples per pixel, large light source, k=.05 for the tonemap.

Image 2: 64 samples per pixel, large light source, k = .05

Image 3: 256 samples per pixel, large light source, k = .05
