UNIVIS-2000: An indigenously developed comprehensive visualization package

This paper describes features of UNIVIS-2000, an indigenously developed MS-WINDOWS-based package for physicists, chemists and molecular biologists interested in modelling medium-sized molecules and visualization of molecular scalar functions defined over a regular grid or on a variety of molecular surfaces. The code is written in C⁺⁺ using freely available public domain graphics library, COSMO3D. The package provides essentially all the traditional features of molecular viewing softwares as well as visualization of scalar fields using planar pixel plots, contours and isosurfaces. A novel feature of UNIVIS-2000 is its ability to create composites of the functions, allowing scientists to quickly view an overall effect of one function over the other. For chemists, such a feature presents an opportunity to view the effect of one molecule on another with a change in their relative positions, providing valuable guidelines for exploration of molecular interactions without doing expensive calculations.
