OK, I give up. Does anyone know how PyMOL does such a nice job creating a molecular surface so quickly? While it looks to me to be an approximation, it's a pretty good one -- at least as good as Jmol's in some respects. Wondering what algorithm is being used there.

Now that we can import PyMOL isosurfaces into Jmol without any trouble:

PyMOL> show structure
PyMOL> save xxx.obj

Jmol> isosurface OBJ xxx.obj offset @{ {*}.xyz }

(Jmol 12.1.24 does not require the OBJ keyword.)
