构造上的

NURBS has become a representation standard for geometric design systems since 1990.However, it is difficult to model complicated objects with only one NURBS surface patch due to its rectangular domain, and it still suffers from serious limitations in surface stitching.

九十年代以来，NURBS曲线曲面已经成为计算机辅助设计系统的表示标准，由于NURBS曲面定义在矩形域上，难以直接用一张NURBS曲面来整体表示复杂曲面，需要采用分片构造的方法才能达到目的，使得拼接边界处的光滑性也受到了严重限制。

The process keeps the functions of the theory but get ride of all the complexity, so to bring the theory into play.

本文提出的构造性体系从根本上摆脱了状态组合和计算复杂性所带来的不利影响，保留了理论的指导性作用。
