Catmull-Rom cubic spline...

[aupetit]

Hi,

I would like a (hyper-)surface to pass through some given points.
I am looking for a simple way to compute the gradient (tangente
hyperplane)
at a point knowing the "height" of its neighbors.
The Catmull-Rom approach works for curves (intrinsic 1D) but does
it exist some similar methods for surface (intrinsic 2D) and even
hyper-surface (more than intrinsic 2D)?

Thank you

Michaël Aupetit
