MacMolPlt is: * A modern graphics program for plotting 3-D molecular structures and normal modes (vibrations). Modern means: o Mouse driven interface for real-time rotation and translation. o copy and paste functionality for interfacing to other programs such as word processors or other graphics programs (like ChemDraw). o simple printing to color or black and white printers (publication quality). o multiple files open at once. * It reads a variety of file formats including any GAMESS input, log or IRC file directly to create animations of IRC's, DRC's, and optimizations. You may also import a $VEC group from any file (such as a GAMESS .DAT file). In addition xMol XYZ files, MolDen format files and Chemical Markup Language (CML) files are supported. Also some PDB file support and MDL MolFile support is included.
