An efficient region suppression algorithm for B-rep model

This paper presents a simplification method for B-rep (boundary representation) models through region suppression. It suppresses every complex unwanted region of a B-rep model as a whole so as to effectively and efficiently generate a simplified version of the original model that preserves the rough shape. In this method, the new surfaces that are used to cover each suppressed region are constructed based on the decomposition of the boundary loops of the suppressed region, rather than through the time-consuming face extension and intersection operations widely adopted by previous works. The experimental and evaluation results are given to show the efficiency and robustness of the method.
