This is the viewer described in the paper. Double click on the face to
start. You will see the markers on a face as described in the paper. You
need to use the following keys to control the animation:

* Function keys F1-F5 - Load Exhibit 1-5 respectively

  F1 - Average of pre-surgery motions compared to average of 12mos 
     post-surgery motions restricted to Skeletal Class II without an Open Bite
  F2 - Same as F1 but restricted to Skeletal Class III
  F3 - Same as F1 but restricted to open biters
  F4 - Motions above and below the average by one SD in the direction of
       the first principal component
  F5 - Motions of Skeletal Class II (no open bite), Skeletal Class III,
  Skeletal Class II (open bite)

* Arrow keys rotate the view

* a - show first  face moving

* b - show second face moving

* c - show third (if available) faces moving

* x - show all faces moving

* m - toggle the animation between smile, eye open/close, cheek puff, lip
  purse, grimace, mouth open and natural smile.

* < and > - increase/decrease face size

* ESC key to exit

How fast the animation displays depends on your hardware and
particularly whether a 3D video card with OpenGL acceleration is
installed. This is just a demonstration program. No warranty is given
or implied. 

The directory contains the following files

face.exe
	The Windows executable that illustrates the facial motions
	described in the paper.

glut32.dll 

	   A dll for the GLUT library used for the Windows version. If
	   you already have this on your system - you may get a message 
	   about a conflict.  Remove the oldest version.

face-data
	Directory containing the  data used to produce the facial motions
