If I have a triangle defined by three 3d vectors and a point (x,y,z). What is the fastest method to find out whether the point is inside the triangle or not. The last truth is that there is no magic(Feist)

I had quite the same problem (finding out whether the intersection point of a triangle with a ray / line lies inside the triangle or not), but the guys over at the Graphics Programming and Theory Forum helped me a lot. The post is called "intersecting triangles with lines" and was started by Chappa (hey, that''s me!).

Hi,
you could also have a look at http://www.acm.org/tog/resources/RTR/ , there''s a .pdf on ray-triangle- and ray-box-intersections, which might be useful.
