I'm developing a 3D system, and now I have a problem. Let me describe it: Let there be three vertices A,B and C. These three vertices (= 3D points) describe a triangle. Then there are two more vertices, P1 and P2. P1 ist the start point of a line, P2 is the end point of that line. All coordinates of all vertices are known. Now I have to find out if the line goes through the triangle. A description of a solution would be nice. Source code would be nice, too. Please help! Tomorrow is my last possibility to check my email!
