Abstract

Solid modeling plays an important role in CAD, automated assembly and recently has found applications in robotics. Constructive Solid Geometry (CSG) is one of the most popular methods used for representing solids. It preserves the 3-D structure of the object; also it provides a hierarchical representation which is useful in representing complex objects. Yet the representation is only syntactic. Many applications using solid modelers need additional information such as physical, behavioral and functional properties of the objects. This paper incorporates these properties on CSG representation of solids and provides semantic constraints for manipulating these properties. Selection of the set of properties and the appropriate constraints depends on specific application. Three applications - finite element analysis, model-based robot vision and automated assembly are chosen in this paper for illustration. The goal is to embed this approach in a geometric reasoning system.
