(...) Don, this is what I do for planar rubber bands and it works great if the two pulleys are in the same plane. But I can imagine a four pulley configuration where the first pulley is parallel to the YZ plane, the second pulley is parallel to the (...) (22 years ago, 21-Jan-03, to lugnet.cad.dev)

(...) It sounds like you want the intersection point of the 2nd circle with the plane of the first circle. I guess that should be exactly one point unless they're in the same plane. However, I don't see how the rubber band gets back to the first (...) (22 years ago, 21-Jan-03, to lugnet.cad.dev)

(...) With two circles in the same plane you can have four possible tangent lines. LSynthcp uses this to calculate straight line segments of rubber bands around pulleys. In 3D space you can have circles that are tangent along one line. Imagine a (...) (22 years ago, 21-Jan-03, to lugnet.cad.dev)

(...) What have you tried so far? And which tangent? Think about it, there's an infinite number of solutions. Even on a plane there are multiple solutions. Recommendation: start with the book _Computational Geometry in C_ by Joseph O'Rourke. -Erik (22 years ago, 21-Jan-03, to lugnet.cad.dev)
