(...) I'm using a simplified form of bezier curves, like you see in most drawing software like coreldraw etc.. this is also x = f(t), y = g(t) and z = h(t) with f, g and h being a*t^3 + b*t^2 +c*t + d . a, b , c and d can than simply be calculated (...) (24 years ago, 26-Nov-00, to lugnet.cad.dev)

(...) I've thought about using bezier curves but I decided to choose another type of curve because it doesn't allow you to make the curve pass by a specific point (except the first and last points).

(...) Doesn't this complicate things a lot? It is possible easily draw a hundred beziercurves that make up 1 curve, but how do you make 1 equation that passes through a hundred points? (...) mean (...) segment (...) it (...) with (...) segment in (...) (24 years ago, 26-Nov-00, to lugnet.cad.dev)

(...) Sorry, I explained myself poorly, I divide the curve in segments with only 2 points each. Bezier and Hermite curves are very similar, but I don't use Bezier curves because the control points are not very user-friendly, I'd rather have tangents (...)

I've now used the upvector and your rotation matrix. Makes things a lot simpler. Thanks a lot for the tips. koen (24 years ago, 8-Dec-00, to lugnet.cad.dev)
