Eeeerrr I can help you with the doc, but with maths, I 'm afraid I can't
(copy/paste from POV3.5 doc 6.1.9)
Splines give you a way to define 'pathways' through your scenes. You specify
a series of points, and POV-Ray interpolates to make a curve connecting
them. Every point along the spline has a numerical value. A good example of
a spline is the path of a moving object: the spline itself would be the path
traced out by the object and the 'parameter' would be time; as time changes
the object's position moves along the spline.
Therefore, given a time reference you could use this spline to find the
position of the object. In fact, splines are very well suited to animation.

Marc
