UNIVIS-2000: an indigenously developed comprehensive visualization package

Abstract

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