README

This is the code accompanying Ken Musgrave's chapters in:

"Texturing and Modeling: A Procedural Approach," by David S. Ebert, ed.,
F. Kenton Musgrave, Darwyn Peachey, Ken Perlin, and Steven Worley.
Academic Press, 1998.  ISBN 0-12-228730-4.

There are four directories or folders:

	Cloud
	GritzShaders
	Multicolor
	TextureCCode

Cloud:

This contains a complete, minimal C implementation of a QAEB ray tracer.
It is capable of rendering both terrains and clouds.  Compiling it as is, it
will render an image of a cloud with single scattering.

The basic fractal and multifractal functions described in Chapters 10 and
12 reside in fractal.c in this directory.

GritzShaders:

This contains all of Larry Gritz's RenderMan shaders.

Multicolor:

This contains a micro-renderer that makes an image of the "multicolor"
texture described in Chapter 11.  This texture is so brittle, that I include
the entire renderer, just to show that it *can* work, though it'd be hard
to reproduce accurately, as in a RenderMan shader.

TextureCCode:

This is the original C code on which Larry's RenderMan shaders are based.
