                DESCRIPTION
This tutorial aims to teach the OpenGL programming language and 
hence graphics programming in a quick and easy manner.  

You are encouraged to refer to other tutorials available on the web on
this subject matter, and refer to books on OpenGL to further increase your
grasp of this subject.

                REQUIREMENTS
To use this package you'll need:

Unix/Linux:
        Tcl version 7.4 or later.
        Tk version 4.0 or later.
        X windows
        OpenGL version 1.1 or later
        Mesa version 2.3 or later

Unix Systems Installation: 
If you are reading this, I am assuming you have successfully
unzipped and exploded the files.
1) $> cd POT where $> is your system prompt
2) $> wish Configure.tk where $> is your system prompt
   The Configure.tk script will ask you a few questions regarding the
   paths for wish, the OGL/Mesa include files and libraries.  Once
   you supply this information, this script will update all necessary files
   and exit out.  You need to do this only once.  Now you are ready to run POT.
3) At the command prompt type in Tutorial.tk to run POT

4) To Conserve hard drive space, I have included an UnPack, and Pack command
   with each chapter.  Use the UnPack option to create the executables
   associated with each chapter.  
5) Use the Pack option to delete the executables to free up disk space,
   when done with a chapter.
 



                         DISCLAIMER
I've tried to make these lessons accurate and complete enough to be
useful, but I won't guarantee that I've succeeded.

This code has been tested on DEC OSF1, SGI IRIX 6.3. platforms using
both SGI's OpenGL and Brian Paul's Mesa.
