WALKING ROBOT README FOR SGI
*******************************************************************************

Program     :  The Walking Robot
Author      :  Jason Waltman, CS Graduate, University of Utah
Class       :  CS 6610 - Computer Graphics - Hansen

Date        :  20 September 2001

*******************************************************************************

Files included are:
   - openGL1.cc (Shell C code)
   - makefile (Compilation makefile, uses CC)
   - readme.txt (You're looking at it)

To compile:
   - run 'make'
   - created executable 'openGL1.sgi'

This version of The Walking Robot implements the following:
   - Start / Stop Animation
   - UI through GLUI controls
   - Reset View
   - Command line specification of eye, look at point, and up vectors
   - Command line specification of window size
   - Mouse can pick limbs when animation is stopped and move them
       constrained by the limition of the joints
   - Choice of speed through radio control (however on a slow computer
       with little gfx hardware it'll still be slow)

*******************************************************************************

This program renders a human-like robot image to the screen an animates it
to imitate walking or running.  The user may change his/her view of the
robot using the GLUI controls on the right side of the main window.

If animation is stopped (via checkbox) the user may click (and hold) a limb 
with the left mouse button.  Keeping the button held down and moving the
mouse will move the limb (some experimentation is required to figure out 
which mouse direction will move the limb the way you want).  The movement
is constrained by the joints and the range of motion is limited to the range
of the motion when the robot is animated.  Choosing to animate again will 
gently move the limbs back to the starting position and animation will
continue normally.

The button "Reset View" will put view in the default viewing position or--if
specified--to the original command line arguments that specify the eye, look
at, and up vectors.  The "Quit" button exits the program.

The keyboard keys "R" and "Q" may be used for "Reset" and "Quit" respectively.

*******************************************************************************

Command line argument syntax:

	openGL1.sgi [args]

The arguments [args] are as follows (begin with '-'):
   -e x y x        specifies eye point vector
   -a x y z        specifies look at vector
   -u x y z        specifies up vector
   (above: x, y, z are floats)

   -sx x           specifies width of window
   -sy y           specifies height of window
   (above: x, y are integers)

Explainations:
   - Robot material properties were chosen only to give the robot a silver
     looking effect.  No more thought was involved.
   - Ground color was completely arbitrary.
   - User may 

Limitations:
   - No error checking is done on the command line arguments.  Enter them
     carefully!  Undefined results if not entered as specified above!!
