Basic Whitted-style Raytracer
Here are two sample images from my raytracer using the given
models. There are a lot of artifacts in the second image
from ray self-intersections with the transparent sphere
causing the "surface acne" that Eric Haines
mentioned. The shadowing is also not done properly with
the transparent sphere. These issues will be fixed in the
next version of the raytracer.
