By comparing the least distance between subdivided control mesh and limit surface 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 limit surface 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。

For swarf cutting, the user selects the top and bottom curves to machine, and a check (or limit) surface.

对于SWARF加工而言，使用者需要选择加工部位的顶部和底部曲线，并选择一个检查面。

There is a limit to the lifetime of these features: Europa's surface is relatively young, having been resurfaced by currently unknown processes some 50 million years ago.

On the surface, the clues strongly imply that Voyager 1 has passed the limit of our solar system's influence.
