摘要
CAD/CAM中用有理多项式函数表示曲面越来越广泛。由于非均匀有理B样条(NURBS)可以精确表示解析形状和自由曲线曲面,国际标准组织(ISO)与1991年把NURBS作为表示工业产品几何形状的工业标准。这里主要讨论了NURBS曲线曲面重构的方法。
Denoting curves and surface with polynomial is used widely in CAD/CAM. Since its rich geometric properties allow it to represent both analytic shapes and free - form curves and surface, ISO defined non- uniform rational B - splines （NURBS） as industry standard for representing geometry in 1991. The prime attention is the reconstruction method of NURBS curves and surface in the paper.
