Actually, VisAD volume rendering is more complex than the
Delaunay.main() logic. Volume rendering from Linear3DSets
creates six different sets of transparent faces and switches
between them as the volume rotates. There is no good way to
do this with Irregular3DSets or even Gridded3DSets.

Your best bet is to resample your Field to a Linear3DSet
that covers the same volume as your Irregular3DSet.

Good luck,
