摘要 采用重复平均的方法对细分曲面进行平滑细分,提出一种基于四边形网格的新细分算法.该算法每细分一次四边形网格,其数目增加为原来的两倍,所以此细分算法具有网格几何操作简单,所得网格数据量增长相对缓慢的优点,应用广泛,更适合3D信号网络传输等应用领域,并且生成曲面在规则点具有C2连续性,在非规则点具有C1连续性. In this paper, using the method of duplication average subdivision surfaces smoothing Subdivision,a new stationary subdivision scheme is presented for quadrilateral meshes. Once this algorithm subdivides a time of Quadrilateral Meshes, the number of the Quadrilateral Meshes increases for original two times. The simplicity in ge- ometric operation and the slow topological refinement make the subdivision scheme more suitable for many applications, such as 3D image reconstruction and network transmission. The resulting surface is C^2 continuous for regular vertices and C^1 continuous for extraordinary vertices.
