MacMolPlt has a mouse-driven interface for real-time rotation, along with copy-and-paste functionality for interfacing to other programs, such as word processors or other graphics programs. MacMolPlt includes simple printing to color or black-and-white printers (publication quality). Multiple files can be opened at once, and it reads standard MolPlt (.mol) files punched out by GAMESS and READ by the X-windows program MolPlt. You may now read in any GAMESS log or IRC file directly, thus creating animations of IRCs, DRCs and optimizations. You may also import a $VEC group from any file (such as a GAMESS .DAT file). There is some PDB file support, and MDL MolFile support is included. You may also paste GAMESS and Gaussian-92 style cartesian coordinates directly into the program. Animation of Normal Modes and of IRCs and DRCs - including orbitals - is available. Multiple GAMESS files can be grouped together to create a single animation! Build molecules from scratch using cartesian coordinates! A 24-bit color display with lighting and shading using QuickDraw is also available!
