Very cool!  How do you set the origin for the viewport?  One thing you 
might want to do is to provide a number box for azimuth, elevation, and 
z-angle, and z-distance (optional, for zoom) from the origin to the 
camera.  That's the easiest way to reset your view when things get 
squirrelly from the oval graphic control or revisit an angle that you 
liked previously.
