Excuse the follow-up question if it is naiive :-) but without the =
angles, doesn't positioning code like physics become problematic?  It is =
easy to look at a car bouncing off a guardrail and calculate a reflected =
angle and new heading vector from an angle, but how would I go about =
doing that with matrices only?

Thanks,
Brett
