摘　　要：论文主要研究混合网格的曲面细分问题,提出了一种带有可调参数的细分算法。该算法适用于多边形网格、三角形网格,以及两者的混合网格情形,且对开的和闭的拓扑结构都能进行处理。由于在算法中引入了可调参数,这样既可产生光滑曲面,也可产生具有尖锐特征的曲面,且通过调整参数还可产生标准的Catmull-Clark细分和Loop细分。另外,实现该算法不需要复杂的数据结构。An adjustable subdivision algorithm is proposed with parameters which is based on combined meshes.The algorithm can be applied to polygonal meshes,trianglar meshes and combined meshes which are open or closed topological structures.Not only smooth surfaces but also surfaces with sharp features can be generated by adjusting the parameters.We also can get standard Catmull-Clark and Loop subdivision sufaces from this algorithm.Moreover,the proposed algorithn has apparent advantage in avoiding the complicated data structures.
