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.
Thanks,
Kevin
