Tangents on a 3d-cubic-spline
Hi! I'm looking for a way to find tangents to points on a SplineFunction. I have a dataset of 3-dimensional coordinates and use SplineFit to generate a SplineFunction that can be plotted with ParametricPlot3D. How do a calculate tangent vectors for my SplineFunction at given points? Thanx in advance Philipp gunz at treangeli.at Sent via Deja.com http://www.deja.com/ Before you buy.
