My best guess is that there is some problem with your
normals, or even errors in your geometry. The attached
jar file includes a Python program dna.py and a data
file dna_molecule.txt read by the program. This
program draws atoms as octahedra (poor man's spheres)
with no problem. Also, VisAD draws vary complex shapes
including spehres as iso-surfaces without problem.
