As you know, Michael's suggestion is the way to go.
The only thing to consider is that when drawing to an IDLgrBuffer IDL
uses the software renderer. In your case this doesn't matter since
you're rendering IDLgrVolume objects which force IDL to use the software
renderer anyways. But sometimes you want/need to use the hardware
renderer. In these cases you have to render to IDLgrWindow and the only
solution to your type if problem is to just start recording your
animation and take the rest of the day off :) er, I mean go to the
library and catch up on the literature...
