When I first heard of raytracing I assumed that non-reflective objects where
done with some sort of 'radiosity' method (though I hadn't heard of the term
radiosity) and I always wondered how they got everything looking so flat!
How are non-reflective objects don anyway? Does the ray just stop if it doesn't
hit a light off the surface? Trying to imagine it, it almost seems like
ray-tracing with radiosity would be easier than without radiosity! I guess an
easy cheat method is used?
