Abstract
This paper presents techniques for reverse engineering of objects containing faces with multiple loops (faces with holes, slots, etc.) wherein these internal loops are specified as constraints on the underlying surface. Non Uniform Rational B-spline (NURBS) surfaces are used for the representation of the faces with the constrained regions specified analytically. The algorithm for fitting of NURBS surfaces to a set of data points is first discussed and then the conditions necessary for joining two patches with the desired continuity (either C super(0), G super(1) or C super(1)) are developed. Finally the concepts developed are illustrated with three examples. This paper thus brings together the initial results in the development of a constraints based system for reverse engineering of multiple loop faces in a B-Rep based modeler context.
