This program uses the sphere primitives to render molecular models.

The following describes the functionality of each mouse button.

Middle            - Rotate the model objects about its center.
Left              - Scale the model objects.
Left+Middle+Right - Translate the model objects in the z plane.
Left+Middle       - Zoom in or out.

The following describes the functionality of each button in the control panel.

Help              - Click the help button to exit this window.
Model             - Scroll through the different available molecular models.
Reset             - Reset the model objects to their original size, and put 
		    the point of view back in its original position.  If the 
		    objects are rotating, pressing the Reset button will stop
		    them.
Quit              - Quit the program.
Sphere Depth      - Click the left mouse to decrease the tessellation depth
                    level.  Click the middle mouse to increase the tessellation
                    depth level.  The depth range is 1 through 30 inclusively.
Sphere Prim       - Scroll through the different display primitive options.
                    The options are: mesh, polygon, line, and point.
Sphere Type       - Scroll through the different sphere tesselletion types.  
                    The options are: oct, icos, bary, cube, and bilin.
Orient            - Toggle orient mode on/off.  When on, the sphere is
                    displayed in a fixed orientation independent of world
                    rotations.
Hemi Sphere       - Toggle hemi sphere mode on/off.
Draw Quick        - Toggle Quick drawing on/off.  In quick-draw mode no 
		    antialiasing or accumulation processes are done.
Display Bonds     - Toggle the display of the bonds on/off.
Display Atoms     - Toggle the display of the atoms on/off.
Accumulate Atoms  - Toggle the accumulation of the atoms on/off.  In this
                    mode, successive whole-scene antialiasing is done.  When
                    the objects stop moving, the static image is accumulated
                    in the accumulation buffer with slight perturbations.  The
                    way the perturbations of the atoms are done is controlled
                    by roll mode and spin mode.  The final image is
                    antialiased.
Smooth Bonds      - Scroll through the different line smooth levels.  The
                    different levels are: off, on,  and smoother.
End Correct Bonds - Toggle the End Correct mode on/off.  In end correct mode
                    the end point of the bonds are antialiased.  This is
                    visible only if the atoms are not displayed.
Accumulate Bonds  - Toggle the accumulation of the bonds on/off.  This is an
                    alternative way for displaying smooth lines.
Radius            - Use the left mouse button to change the relative size of
                    the atom radii while dragging the vertical bar.
Multisample	  - This will toggle full scene multisampled antialiasing 
		    on a suitable RealityEngine configuration.
Stereo	  	  - This will toggle in-the-window stereo on
		    a suitable RealityEngine configuration with the proper
		    monitor configuration (setmon 960x680_108s).

The Following Keys have useful functionality:

O/L		  - Will increase/decrease, respectively,
		    the separation for each eye when in stereo.
