【摘要】 提出Bézier曲线的近似弧长参数化方法及相应的算法.给定一条Bézier曲线,利用曲线参数域的一个二次变换对曲线进行重新参数化,使得曲线的参数化更接近于弧长参数化.该算法的关键是所使用的变换保持曲线的正则性.实验证明,用文中方法进行重新参数化之后,曲线上点的分布得到了改善.更多还原

【Abstract】 By using reparameterization with a quadratic transformation on the parametric domain,an approximate arc-length parameterization method and the corresponding algorithm are presented for Bézier curves.The key of this algorithm is to choose suitable transformation for preserving the regularity of the given curve.Experiments show that the distribution of the points on the curve has been improved by using the proposed method.更多还原
