By comparing the least distance between subdivided control mesh and limitsurface with rough machining allowance, the uniform subdivision depth was determined.
该算法以细分后的控制网格与极限曲面之间的最小距离和粗加工余量作比较，确定均匀细分次数。

As a result, the limitsurface of the polygonal mesh containing the symmetric zonal meshes is the subdivision surface satisfying the curve interpolation constrains.
因此，含有这种对称网格带的多面体网格的细分极限曲面即为满足曲线插值约束的细分曲面。
