摘　　要：提出通过非均匀B样条曲面的小波分解以及能量法的结合对曲面光顺的算法。小波分解实现了数据的压缩,提高了算法的效率;同时结合能量法对分解后曲面的细节部分进行边界约束光顺处理。最后用实例验证了算法的有效性。A surface fairing approach is presented.The fairing of surface is realized through the decomposition of B-spline surface and energy optimization.The decomposition of B-spline can improve the efficiency of the algorithm by compressing data,and fairing detail parts with boundary constraints are realized through the energy optimization.Several examples are pre- sented to validate the effectiveness of the proposed algorithm.
