* CLASS: Scene3D							*
* AUTHOR: Jean-Francois DOUE						*
* LAST MODIFICATION: 12 Oct 1993					*
*									*
* This class implements a 3D scene.					*
* The scene is composed of a camera, a collection of light sources	*
* and a collection of primitives to render.				*
* The scene is capable of ray-tracing itself.				*
* Scenes are typically parsed from a text file description. (see the	*
* README file for a description of the format).				*
