VERIFICATION OF BOUNDARY REPRESENTATIONS OF SOLID MODELS

Verification of polyhedral boundary representations (B-reps) of solid models through the use of an algorithm is addressed here. The validity conditions for B-rep models are presented in a format which leads dir ectly to a set of verification algorithms. The validity verification a lgorithms are intended for design automation through execution after e ach solid modeling operation, after localized geometry modification, o n imported object model databases, prior to storage of object models, or prior to execution of an application program on the solid model.
