Collision Detection
Author
Hi!
My question is: How do I detect if a point is in a triangle?
I know how I can detect if a point is in a plane by knowing the plane normal but what happens is that it creates an infinite plane that is not restricted to the triangle.

there was a discussion about detecting a sphere-triangle collision. Reading that should help you.
Have fun.

Just my 2 cents:
you can check if point is in a region of any shape that doesn''t have overlaping lines by puting one point outside and drawing a line to the point you''re checking. If it crosses (x mod 2 = 1) lines, then it''s inside, but if (x mod 2 = 0) - outside
