The problem is actually pretty simple. Using a simple
cubic bezier-spline as input (2 Nodes, 1 Direction for each
node = 4 Vectors), I want to calculate the outward
pointing direction of any point on the spline.

Think of the centrifugal-force when driving around a
corner. That's what I want to calculate.

I know that Chris Colefax has done a macro for
splines, but I can't see through his algorithms. Any
suggestions, reference PDF-Files, or whatever?
