提出了一种基于由给定控制多边形定义的指导向量构造隐式代数曲线的方法.同时推导了所生成的代数曲线的表达式并具体分析了其性质.这种方法可以用来构造插值曲线,而且曲线的形状很容易修改与调整.此外,该方法也可直接推广用于构造隐式曲面.
A method was proposed to construct an algebraic curve from the given control point set based on the guidance vectors of the control polygon defined by these points was proposed.After deriving the curve s expression and analyzing its properties,it was applied to constructing a interpolating curve whose shape can be modified easily.The method can be directly generalized to construct implicit surfaces.
