Here is an example of a 3D scatter plot in which I use the ORB
object as points.

http://www.dfanning.com/tip_examples/scatter_surface.pro

The ORB object is hard to find. I located it here:

IDL_DIR/examples/doc/objects/orb__define.pro

The ORB object has a radius that you can set in
the data coordinate space.

Cheers,

David
