- // 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.
