We are thinking of buying a 320H for solid modeling, in particular
molecular modeling using Phigs.  The IBM specs for the 320 with
24bit graphics are 10K Gouraud shaded polygons/sec.  Is this fast
enough for real time video?  Does anyone have experience with such
an application on an R6000?  Is it possible to save the frames
and play them back at video speeds if that raw rate isn't fast enough?
Any experiencce making video directly from an R6000?  Any advice would be 
appreciated.  We are also considering an HP 720 PRX, which rates at 21K polygons
/sec, but is 16 bit (8+8) rather than 24.  We appreciate the help.
