// Persistence Of Vision raytracer version 1.0 sample file.
//---------------------------------------------------------------------------
// This scene file was designed to emulate the digitized photographic image
// of a crystal sphere { on a checkerboard that David Buck took, and to
// verify or refute the correctness of the current refractive functions
// in POV-Ray. The original image is available on CompuServe
// (go comart), Library 17 by the name of crysta.gif.
// Experiment with the index-of-refraction value for the crystal ball.
