Okay, I'll settle for the short answer. If someone's got some spare time, I
won't complain about getting a long answer, but if you say so, then I'll
(just this once ;-) ) believe you.

Perhaps I'll just do some research on raytracing to find out why one would
need more intersections. Thanks for the tutoring! :-)
