notes:

There are some serious problems in this 
problem set.

You use the wrong normal when intersecting
with a polygon.  

You forget to multiply the reflective 
radiance by the object's shininess before
passing it on.

These are minor errors.  However, your
calculation of transmission is wrong.
There is also an error in the code that
makes it hang when the ray tracer encounters 
a transparent object.

You also forget to set the distance to the 
when casting shadow rays.
