VMD is a molecular visualization program for displaying, animating, and analyzing large bio molecular systems using 3-D graphics and built-in scripting. Although VMD is an open source program, this advantage is not useful when it is used with CAVE systems since it uses a commercial application called the “CaveLib application. As part of the international DIVERSE community, the Vista team developed a version of the VMD which allows for using DIVERSE (an open source application). This version will allow VMD to be totally open source in both desktop and CAVE modes.
