//               Persistence of Vision Raytracer Version 3.5
//                           Screen Include File

// Created by Christoph Hormann, Chris Huff and Rune S. Johansen.

// Screen.inc will enable you to place objects and textures right in front
// of the camera. One use of this is to place your signature or a logo in
// the corner of the image.

// You can only use screen.inc with the perspective camera. Screen.inc
// will automatically create the camera definition for you when it is
// included.

// Note that even though objects aligned using screen.inc follow the
// camera, they are still part of the scene. That means that they will be
// affected by perspective, lighting, the surroundings etc.

// For instructions of use, look in the POV-Ray manual, and for an example
// of use, see screen.pov.
