// Persistence Of Vision raytracer version 3.0 sample file.
// Demo using the spiral2 texture ... by Dieter Bayer, May 1994
//
// 9 discs with different spiral2 textures.
//
// The scaling factor of the texture, i.e. the number of turns
// one "arm" of the spiral makes, decreases from left to right.
//
// The number of "arms" of the spiral,
// increases from top to bottom.
