I know it can get tricky to do intersection in 3D, but on the link I sent, it is described under "In three dimensions,...". See also this: http://stackoverflow.com/questions/10551555/need-an-algorithm-for-3d-vectors-intersection/10554546#10554546 One has to code this, using symbolic algebra, but once you have it, the rest seems straightforward. I would think it would take a few days to get it right. Ondrej -- You received this message because you are subscribed to the Google Groups "sympy" group.
