The POV-Ray SDL code in two files in the attached zip-file has macros that
creates functions that can be used to make splines like POV-Ray's built-in
(cubic) natural_spline. (There's also code that shows how to use the macros.)

I made this to illustrate a possible way to make cubic splines, as discussed in
this thread:
