ABSTRACT
We have implemented extensions
to the Brookhaven Protein Data Bank (PDB) file format
for incorporating scene information such as viewing parameters,
additional molecular information (e.g.,
van der Waals radii and atom colors) and user-defined graphics.
These extensions were made in conformance with the PDB standard and provide
sufficient information to render the scene in various styles
such as space-filling images and ribbon diagrams.
For the past 5 years
these extensions have been used in the MidasPlus molecular modeling system
and have proved both powerful and sufficient for generating complex
molecular images.
We propose that the extensions to the PDB presented here be adopted
by the molecular modeling community for incorporation
into visualization programs.
