A point P is inside triangle ABC iif the angles add up to 2pi. (APB + BPC + CPA == 2pi) Thought I'd share too, don't have a point. :) graphics programming / dot product is neat. Actually, there are some pretty fun graphics algorithms. I could ramble on about some, but don't want to intrude / doubt anyone cares but me, heh.
