I need to know how the Cubic interpolation on splines is calculated. I need it for an external application I'm doing that needs to calculate any point along a spline with Cubic interpolation.
What I need, is a routine where I can input a set of points (their x,y,z coordinates) and a value between 0 and 1. A value of 0 will return me the coordinate of the first point and a value of 1 will return me the coordinate of the last point. Any value between 0 and 1 would return me the coordinates of the point of the spline at that percentage point.
Also, a way to define if the intermediate points have a distribution of Natural, Uniform or Adaptive, would be nice... but I could live with only one of those... whatever it is.
Any help? Please!!
Thank you in advance.

Well, none of the Maxon programmers responsible for coding the splines reads this? Or anyone that knows someone that does? ;-)
Come on, is it sooooo hard? Pleeeease.
Thank you.
