Images displaying a combination of solid bond, ball and stick, and space-filled models are possible.
The user can control individual atom and bond visibility, size, and coloring, as well as the orientation and center of the model view. All sphere and cylinder commands written in the scene description script are annotated with atom identifiers allowing the appearance of every atom and bond in the model to be manually changed. The output of the program is intended to represent a starting point in preparing more elaborate images of molecular structures using the advanced rendering capabilities of the POV scene description language. Requriements You'll need Perl 5.004 or later to run ppovit. Although not essential, a molecular viewer program is also usefull for obtaining the view parameters that ppovit uses to orient the molecular model.
