I'm putting in another plug for the volume() new-graphics wrapper around the
IDLgrVolume object. IDL's volumetric rendering capabilities really are very good,
and Chris Torrence's partial implementation already is very useable. For what it's
worth, my group has a figure rendered by this routine on the front page of
Physical Review Letters today
( http://physics.aps.org/synopsis-for/10.1103/PhysRevLett.109. 163903).

All the best,

David
