notes:

Good job on a tough problem set. There were a few problems with your
code:

Some white sprinkles appeared when the surface normals were nearly
perpendicular to the direction of view (so at the edge of spheres and
such.

Transmission direction calculation was incorrect.

The specular radiance calculation was incorrect, resulting in very
large and bright specular highlights.

Supersampling, jittering, RayTraceStart and RayTraceFinish were not
implemented.
