// Persistence Of Vision raytracer version 3.0 sample file.
// POV-Ray scene description for chess board.
// By Ville Saari
// Copyright (c) 1991 Ferry Island Pixelboys
//
// This scene has 430 primitives in objects and 41 in bounding shapes and
// it takes over 40 hours to render by standard amiga.

// Note : CHESS2.POV was created from Ville Saari's chess.pov
// -- Dan Farmer 1996
//  - Cchanged textures
//  - Added camera blur and changed focal length
//  - Use sky sphere
//  - Modularized the code
//  - Added felt pads to bottom of pieces
