PERSONAL COMPUTER-BASED VISUALIZATION OF 3-DIMENSIONAL SCALAR AND VECTOR-FIELDS - AN APPLICATION TO MOLECULAR GRAPHICS

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