Hi,
I have a segmented volumetric dataset, and am displaying its segments
in a single 3D image, rendering each segment surface with SHADE_VOLUME
and then POLYSHADE, plotting to the Z buffer to get hidden parts
removed.
This works fine except that all the surfaces are displayed in the same
color. However, I would like to display every segment in a different
color (yet continue to have IDL do the shading and hidden-surface
removal). Does anybody know if this can be achieved and how, or where
I can find material on this problem?

Hey, I am sure David will be happy to provide you with as many copies as
you have bookshelves for :-)
Cheers,
