  Try looking at the molecular modelling demos in buttonfly.  If you set
the level of sphere complexity to 1, set the sphere type to cos, and set the
radius from 0.1  to 0.2, you can actually rotate a 300+ atom molecule in real
time.

   I have looked at the data in ~demos/data... for the program, and it seems
fairly straight forward to try and understand the details.


   To ge more information on the program, you should contact your SGI rep,
and see what they can do for you.
