According to topological structure of controlmesh, we generate generalized rational parametric surfaces in two manners.
对于广义有理参数曲面,根据控制网格的拓扑结构,我们分成两种情况来考虑。

The model used to controlmesh deforming is improved spring analogy with boundary improvement and torsional effect improvement.
网格变形的物理模型采用改进的弹簧近似模型,改进措施包括边界修正和扭转效应修正。

By comparing the least distance between subdivided controlmesh and limit surface with rough machining allowance, the uniform subdivision depth was determined.
