At the time, of course, we didn't have photons or radiosity.  That adds 
a lot to lighting.cpp.

When we started, the C++ compilers weren't very mature and we coded it 
in straight C with OO-like enhancements.  I'm surprised that this 
approach has survived all these years.  POVRay still doesn't use C++ 
classes.

There was a time when we had implemented refraction wrong.  The images 
looked ok, but they weren't correct.  To test it, we took a glass sphere 
that a friend of mine had, put it on a real checkerboard and 
photographed it. By modeling this scene in POVRay, we could see how well 
the refractions matched.

Aaron is doing some consulting work in Chicago.  If I heard correctly, 
he had a bout of cancer and is now in remission.
