Contents of the README file

The source is Copyright (c) 1990-1991 by Apple Computer, Inc. You may not use
it in anything for which you charge money, beyond reasonable fees to cover
duplication and handling. If you give your software away, feel free to use
this source.

The source is the implementation of a gem, "Implementing Progressive Radiosity
with User-Provided Polygon Display Routines," that I wrote for Graphics Gems II.
A hard copy of the source can be found in Appendix II of Graphics Gems II.
The source included here is a newer version than the one in the book
and should replace it. For more details on the source and radiosity methods,
please refer to the book.

No warranties expressed, implied, or even hinted at.

The source is written in ANSI C and is C++ friendly (you can include the
.h files in C++ programs).

Please send bug reports and/or enhancements to the author "[email protected]".
I would also like to hear any system that you have ported the source to.
However, please don't ask me for technical support on the source.

C Code From Graphics Gems II, Academic Press, Inc.

This is a list of the files and directories containing the C code for Graphics Gems II.
They are listed in order of their appearance in the book. Beside each file name is the
Gem number, author's name, and Gem title to help you find what you're looking for.
Unfortunately, not all of the code listed in the appendix of the book is here (for various
reasons). The missing ones will be added as they turn up. Changes will be listed at the
bottom of this file.
