A method of constructing rational interpolating surface under local coordinate systems is presented, which can be used to solve the large torsion problem of surfaces. This kind of surface has better approximating effect and its properties can be easily discussed, so it has practical applications not only in CAD but also infinite element analysis and other fields. An example is given in the paper.Projects Supported by the Science Fund of Education Committee. 相似文献

本文提出一种在局部坐标系下构造有理插值曲面的方法,它可用来解决曲面的"大挠度"问题。这种曲面逼近效果较佳,也便于讨论其性质,在几何外形设计、有限元分析及其它领域都有实用意义。文中给出具体的构造实例。 相似文献
