This is version 3.0 of rayshade, a raytracing program.  Rayshade reads
a multi-line ASCII file describing a scene to be rendered and produces
a Utah Raster RLE format file of the raytraced image.

Rayshade features:

	Eight types of primitives (box, cone, cylinder, height field,
	polygon, sphere, superquadric, flat- and Phong-shaded triangle)

	Composite objects

	Point, directional, and extended (area) light sources

	Solid procedural texturing and bump mapping of primitives, objects,
		and individual instances of objects

	Antialiasing through adaptive supersampling or "jittered" sampling

	Arbitrary linear transformations on primitives,
		instances of objects, and texture/bump maps

	Use of uniform spatial subdivision or hierarchy of bounding
		volumes to speed rendering

	Options to facilitate rendering of stereo pairs

	Support for the C-Linda parallel programming language

Rayshade has been tested on many different UNIX-based computers.  If your
machine has a C compiler and enough memory (at least 2Mb), rayshade should
be fairly easy to port.  Be warned that rayshade uses yacc and lex to
process input files.  If you do not have lex and yacc, try to get flex and
bison from the Free Software Foundation folks (ftp to prep.ai.mit.edu).
