title A Review of Solid Shape Modelling Based on Integrity
source Computer Aided Design March, 1984. vol. 16: pp. 66-80 : ill. includes bibliography.
summary The potential benefits of using a canonical model for representing the shapes of solid objects has led to the design and implementation of a number of geometric modelers with varying capabilities. This paper reviews the approaches taken in solid modeling by defining the well-formedness conditions which must be implemented in any modeling system. The methods for satisfying the well-formedness constraints in the various solid modeling methods are reviewed, using the concept of integrity constraints. The incorporation of integrity constraints, both explicitly and implicitly, into solid modelers are considered, with particular focus on boundary modelers. The use of integrity constraints for defining shape families and assembly families are also presented. The result is a unified view of solid shape modeling systems that enables their classification and extension into particular application areas
