Hi,
1). Has someone written a routine that renders spheres  using tmesh routines ?
something of the sort
initsphere( npoly );   /* npoly = number of polygns used to approximate
				      the sphere */
makesphere( x, y, z, radius );

At the moment I generate a unit sphere using adaptive subdivision of an
icoashedron/octahedron, and use a series bgnpoly() endpoly() commands to make
an object ie. initsphere( npoly ). then translate and scale this unit sphere
but since there are > 1000 spheres the drawing speed is sloooow.

The idea of course is to make space filled drawings of molecules and
hopefully (!) rotate a low res ie. initsphere( 32 ) and switch to hi res.
gouard shaded object when done.

Himanshu.
