Abstract
This paper has discussed how to use feature and topology information to compare 3D CAD models represented by polygonal meshes. In this work we propose an enhanced method to compare CAD models based on shape distributions. A topology-preserving simplification method of polygonal meshes was used to simplify CAD model as the pretreatment for generation of sample points. We improved the method of sampling points and a pair of shape functions more sensitive to shape was employed to construct a 2D shape distribution. The experiential results showed that simplification has a positive effort on shape comparison and our method achieved more effective performance than the conventional one. © Springer-Verlag Berlin Heidelberg 2007.
