220.127.116.11 How can I generate a spline?
"How can I generate a spline, for example for a camera path for an animation?"
POV-Ray 3.6 has a splines feature that allows you to create splines. This is covered in the documentation and there
are demo files showing examples of use. There exist also third party include files for spline generation that have
greater flexibility than the internal splines, for example the spline
macros by Chris Colefax.
