Abstract

The Programmer’s Hierarchical Interactive Graphics System (PHIGS) is about to become a standard graph- ics system’ which caters for the definition, display and modification of two and three-dimensional graphical data. PHIGS however, is mainly a wireframe system, and the PHIGS+ extensions to it have been put for- ward to allow the incorporation of shaded 3D graphics into PHIGS. One area that is important to a large constituency and which has so far not been considered in PHIGS and PHIGS+ is that of solid modelling. This paper addresses one aspect of solid modelling by describing a simple method for the representation, evaluation and display of Constructive Solid Geometry (CSG) models in PHIGS and PHIGS+.
