Description

Class for calculating Renner subsplines for given nodes.

Requires NumPy and, for the exampes, Michael Haggerty's Gnuplot module and Konrad Hinsens VRML module.

_normalize(p)

Strip unnecessary zero coefficients

_polynom(val, coe)

Evaluate the value polynom defined by coe for val.

The value is: coe[0] + coe[1]*val + ... + coe[n]*val^n + ... + coe[len(coe)]*val^len(coe)
