MolView and MolView Lite
Molview is a Macintosh application that can read several types of coordinate files and display ribbon, CPK, stick, ball&stick, and surface figures. The interface is completely interactive (i.e. no comand line input). There are countless options that control the display colors and characteristics. The output includes object-oriented PICT, QuickDraw 3D 3DMF files, QuickTime movies, and simple DXF formatted files. In addition, there are several analysis tools such as neighbors, distance lines, hydrophathy plots, Edmunson wheel plots, B value plots (and color coded stick models), distance plots. In addition, the user can open 2 different structures and even perform 3D alignments on them. Also, subsets of the structure can be stored as MOL files and be read in later .
MolView Lite is a simple renderer for the 3DMF files. From MolView, one can output the ribbon, stick, ball&stick, space filling, or rendered tube objects. These files can be rendered in MolView Lite and output as bit-imaged PICT files or as QuickTime movies. As with other 3DMF viewers, the user can interactively rotate the objects and change background colors.

These programs are distributed free of charge but may not be distributed or decompiled for commercial purposes. -Tom Smith
