I'm not too sure what "not-too-cumbersome" means in this
context. Is there a built-in IDL routine to do it? I don't
think so. I've never seen one. Can I imagine writing such
a routine? Yes. I'd definitely do it in object graphics,
because the 3D part of it will be much easier, and you
will be able to rotate it, which will make it easier for
the user to see different parts of it.
It will involve some interesting programming. Some people
consider that cumbersome, but no one on this newsgroup. :-)
Cheers,
David
