摘要
有理 Bézier曲线是 CAGD和计算机图形学中常用的参数曲线。研究了有理 Bézier曲线的几何约束修改。给出了基于控制顶点和基于权因子的约束优化方法 。
Rational Bézier curve is one kind of the most commonly parametric curves in CAGD and Computer Graphics. This paper investigates the modification to the shape of rational Bézier curves with geometric constraint. A new method of constrained optimization is presented in this paper based on changing the control points of the curves or changing the weights. Finally numerical examples are also given.
