Import molecule files for Chemistry or just for fun. Both PDB [Protein Database] and MOL format files are supported. This script works in both max and gmax.
The MDL Chime browser plug-in displays molecule files in the browser.
The VMD program displays molecules and supports a large number of rendering options.
However, while these programs incorporate a knowledge of chemistry, neither of these programs provides fine control over rendering and animation. The Import Molecule max script imports the molecule files and creates max geometry that can be rendered and animated at will.
