Hi, I've been looking all over the net and can't find a source that will tell me how to program a "control point curve" (like the ones 3ds max allows you to create when making NURB curves). If anyone knows anything about the subject (even if it's just a reference to a site or book), please tell me. Keep in mind I have a computer engineering degree; I am not scared of math and know a fair bit about programming. I've also been doing 3d work for years (mainly 3ds max). Also, sorry if this question has been posted before. I'm new to the forums and can't seem to find a search function. Thanks - Hawk

I'm not familiar with 3DS Max, but it sounds like you're talking about a spline of some kind? A quick Google search should bring up lots of references for bezier curves, cubic splines or other kinds of spline - here are some:
