Abstract

Solid modellers are used in a wide range of applications in computer graphics and computer-aided design and manufacturing. Unfortunately, current solid modellers can not be considered as shape-complete machines because not all the shapes can be represented and manipulated using their data structures. In this paper, an alternative solid model based on the theory of cell complexes is suggested and some of its algorithms are outlined to get a better understanding of how it works. It supports the representation and manipulation of dimension-varying shapes independently of whether they are local (vertices, edges, faces, and solids) or not (depressions, protrusions, through holes, voids, and components), and their interactions as well.
