notes:

Good job on a tough problem set! Here are the problems I saw:

The polygon intersection code is wrong. It doesn't seem to be
detecting hits with polygons at all.

The cone intersection code is not quite right -- reverse surfaces are
not appearing in your rendering.

Transmission direction is computed incorrectly.

Specular radiance is incorrectly implemented.
