It was pretty easy to drop it into iTools.
pro sphere, radius, itoolid
oOrb = OBJ_NEW('orb', RADIUS=radius, DENSITY=2.0)
oOrb -> GetProperty, DATA=verts
OBJ_DESTROY, oOrb
iplot, verts, overplot=itoolid
end
Thanks Rick!

I can only get you half-way.
You can get the vertices and connectivity for a sphere from the "orb"
object:
oOrb = OBJ_NEW('orb', RADIUS=2.0, DENSITY=2.0)
oOrb -> GetProperty, DATA=verts, POLYGONS=conn
OBJ_DESTROY, oOrb
What you do with the data in verts and conn in iTools is up to you.
The more general question would be how to get an instance of
IDLgrPolygon into an iTool. If you get an answer to that, then you can
just drop the orb in and forget about the rest.
