Question about intersection of 3-d lines--how to code?
Well i do not code your solution but bring you the basic idea: 1) line1: l1.v1: l1.v1.x l1.v1.y l1.v1.z l1.v2: l1.v2.x l1.v2.y l1.v2.z line2: l2.v1: l2.v1.x l2.v1.y l2.v1.z l2.v2: l2.v2.x l2.v2.y l2.v2.z with this you can find the two equations of each line: with the form... -
