Does anyone know a way to display 3-D objects
on a map projection?
It's easy to display a 2-D field in lat & lon using
TV and MAP_IMAGE, but how can I display a
3-D object in lat, lon, and z in map coordinates?

Can you provide a bit more detail? I can't, er, visualize your
"surface upon this mesh of points". Would this be similar to taking a
sphere and creating a little 3d globe by shifting the vertices up and
down (orthogonal to the surface) based on elevation? If so, there is
a demo of this floating around somewhere. Maybe someone else can help
out here? Was it in the docs? This turns out to be fairly easy to do
if your base object (your ellipsoid) has a regular mesh.

Cheers Rick,
What I actually have is a set of 2D points (x,y) which define an
ellipse, then stacking many ellipses of varying size in the z-
direction gives me what appears to be a 3D structure outlining a type
of ellipsoid. What I would like to do is fill-in the structure so that
I can make it a surface which I can then perform different operations
on, such as taking measurements of widths etc. or doing some form of
illumination with objects light source or other.
