This is "viewer B" 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-F7 - Load Exhibit 1-7 respectively

All show a comparison of the average motion of the patient with

    F1 - control average
    F2 - control average + 2 SDs in direction of PC1
    F3 - control average - 2 SDs in direction of PC1
    F4 - control average + 2 SDs in direction of PC2
    F5 - control average - 2 SDs in direction of PC2
    F6 - control average + 2 SDs in direction of PC3
    F7 - control average - 2 SDs in direction of PC3

* Arrow keys rotate the view

* a - show control face moving

* b - show patient face moving

* c - show both faces moving

* m - toggle the animation between smile, 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
