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 below 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.
