notes:

Your problem set has some serious problems.

You have a bug in your ray casting that
makes everything seem black in recursive 
mode.

There are errors in both your cone and 
polygon intersection routine.  Your cones
are not rendered from certain angles.  Your
polygon routine sets SurfnOS to fnorm without
initiating the latter.

Your transmission routine is buggy and make 
the ray tracer hang when tracing transparent
objects.
