3D voxel plots without polygons? (need advice) [message #5516]

Does anyone know the trick to plotting three dimensional data such
that the intensity of a given data point F(x,y,z) is represented
as a small colored dot in the center of the cube that defines that
particular volume element?

I want a display that will allow the user to "see through" the
entire 3D image, meaning that most of every voxel must be
transparent, with only a small part containing the actual
information. Needless to say, opaque polygons connecting the
verticies would obscure all inner layers of the image, but I
can't figure out how to prevent IDL from plotting these.

If someone has solved this problem, I would appreciate any advice
or code.

Thanks,
