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
