Spline based techniques to make any parametric curve / surface editable

Any parametric curve or surface where the formula is based on polynomials, rational functions, trigonometricfunctions, exponential functions, logarithmic functions, etc. can be made editable by adding some simplestructures. That is, we can easily change the shape of any curve or surface by adding a set of interpolation "points" with associated structures, which can then be moved, rotated and scaled."
