3.4 Spline Based Shapes
After we have gained some experience with the simpler shapes available in
POV-Ray it is time to go on to the more advanced, thrilling shapes.
We should be aware that the shapes described in this and the following two chapters are not trivial to
understand. We needn't be worried though if we do not know how to use
them or how they work. We just try the examples and play with the features
described in the reference chapter. There is nothing better than learning by
doing.
You may wish to skip to the chapter "Simple Texture Options"
before proceeding with these advanced shapes.
