Abstract

UNIGRAFIX is a three-dimensional graphics modeling environment that runs under the UNIX operating system. It comprises a terse, human-readable descriptive language that allows scene files of complex objects to be created with little overhead. These scenes can be used as input to a set of UNIGRAFIX programs which can be run either as separate functional units, or from within the interactive UNIGRAFIX environment. Programs are available to transform and illuminate the scene descriptions and to display them in a variety of styles on various output devices. The built-in hidden-face and hidden-line elimination routines use a scan-line algorithm which makes strong use of scan-line coherence as well as object coherence.
