I am trying to create a 3D visualization in which the color of the objects
varies with distance from the viewer. I have been trying to use Shade_Volume
and then Polyshade to view the results. According to the IDL documentation I
should be able to set the an array, SHADES, to shade the vertices returned
by Shade_Volume and then pass that shading array to Polyshade. The problem
is I can not get apply the transformation matrix, !P.T, and get the geometry
right so the shading varies with distance from the viewer.

Can anyone provide some help? Is there any better way to do this
visualization using IDL?
