To start, you can look at some existing software for PDB molecules
like RasMol. We began to work on the viz. of PDB molecule in CAVE
( http://www.cs.vu.nl/~reanmbot/vr and for example
http://www.cs.vu.nl/~renambot/vr/images/mol2b.jpg ) but we
didn't yet address the problem of large molecules.
Perhaps just points (or pfLightPoints) can do the trick ?
If you need some pointers, email me.
regards,
Luc.
