C3DCON: a stereo 3D electron-density cage contouring and atomic structure plotting program

A Fortran computer program is described which performs three-dimensional electron-density cage contouring together with atomic structure model display on a Tektronix-4100 command graphics terminal hosted to a VAX/VMS computer. The program also supports ball-and-stick visualization of the model, on-line manipulation of the display and convenient hard-copy output. Such a program is useful in a research environment where an expensive graphics workstation is not readily available and hard copies of publication quality are often desired.
