I don't know exactly how to do this, but I do know
I would NOT be using IDL direct graphics to do it.
That's a fool's game, it seems to me. :-)

I think I would try to do something like the Fly-Through
demo, with some kind of map as the base of the elevation
data. Presumably RSI knows how to create map projections
in object graphics. Maybe you could get them to share
that information with the rest of us. :-)

Cheers,

David

P.S. Actually, I think I know how to get something like
a map (I.e., filled continents) in object graphics, but
it is just damn hard and the visualization never gives
me a great deal of confidence in the map's accuracy. :-(
