    Is a Point Inside a Triangle? Testing for Inclusion on a 2D Plane

    What I'm trying to accomplish is to find if a point is within a geometric room consisting of several triangles. I am going to use Jordans curve theorem to find if it is so what I do is the following: 1) Cast a ray from the point (in an arbitrary direction) agains each plane the triangles are in...
