Constructive Solid Geometry (CSG) has been used in several model-based vision programs, most notably in ACRONYM. This paper examines some of the problems that arise with CSG and proposes constraints that make CSG a unique representation of scenes. It is also suggested that Additive Constructive Solid Geometry (ACSG) is more useful for vision because it leads to simpler computation of connectivity, within and between objects, and can be implemented more readily on a parallel architecture.
