Personal computer-based visualization of three-dimensional scalar and vector fields: An application to molecular graphics

A desktop PC-based graphics package, UNIVIS, for visualization of three-dimensional numerical data is described. Apart from routine molecular model visualization, the package provides for a host of other features such as extraction of various surfaces, planar cross-sections of the three-dimensional data, and property texturing. Fast rendering and transparency are the strengths of the present package. These features are comprehensively discussed. The salient features of UNIVIS are presented in the form of visualization of a variety of molecular properties, which are of immense importance in understanding molecular structure and reactivity patterns.
