molecular and crystal model viewer

A GTK+ based program for the display and manipulation of isolated molecules, periodic systems and crystalline habits. It is in development, but is nonetheless fairly functional. It has the following features:

 * Support for several file types (CIF, BIOSYM, XYZ,
   XTL, MARVIN, and GULP)
 * A simple molecular creation and manipulation tool
 * A dialogue for creating starting configurations for
   molecular dynamics simulations
 * Assorted tools for visualization (geometry information,
   region highlighting, etc.)
 * Animation of BIOSYM files (also rendered animations,
   see below)

GDIS also allows you to perform the following functions through other packages:

 * Model rendering (courtesy of POVRay)
 * Energy minimization (courtesy of GULP)
 * Morphology calculation (courtesy of cdd)
 * Space group processing (courtesy of SgInfo)
 * View the Periodic Table (courtesy of GPeriodic)
 * Load additional filetypes, such as PDB (courtesy of Babel)
