Thanks for all your help. I already had the the first part of the problem (ie. finding out which side the point was on), but had a brain block on the 2nd part. Certainly helped. So, thanks.
I always wondered what hats on letters meant: unit vector. Useful to know.
It amazes me that I've forgotten so much of this. I did after all write one of the first (if not the first) 3D physics systems in Blitz, and a fairly complex moving convex hull collision/response system! But, I supposed back then I was much more inclined to follow hunches and intuitions about these things without actually having much of a grasp of the math, or the proper way to proceed.
