Hi rooters, I wish to find out of a point is contained within (or on the surface of) a 3D object. (More accurately I wish to know if a line intersects an object ie a raytrace). Is there such a feedback mechanism in the 3D geometry classes? For a TBRIK its pretty easy, but TTUBE, TCONE etc it becomes much harder.
