Eadfrith: A molecular rendering program for Silicon Graphics workstations

Eadfrith was written to provide the rapid display of molecules, so that they can be interactively rotated, translated, and scaled, and then rendered in a manner suitable for photography or other high-quality output methods. The program provides support for the display of transparency, electrostatic effects, and the normal vibrational modes of molecules. The compiled version for Silicon Graphics machines is freely available over the World-Wide Web. Eadfrith reads the structures from files in MacroModel format. The aim of the program is to provide a way to display molecular structures quickly and to produce high-quality pictures. Consequently, image-saving routines are not included, and standard utilities must be used in conjunction with Eadfrith to save the images to disk.
