摘要 提出了一种修改NURBS曲线造型形状的新方法.对于给定的NURBS曲线,利用遗传算法修改其一个或多个权因子,使曲线经过事先指定的点.实验结果表明算法具有一定的实用性. In this paper, we propose a new way to modify the NURBS curve shape. NURBS curves for a given, using genetic algorithms in this article to modify one or more of its weight factor, the curve specified by the prior point. Experimental results show that this algorithm has some relevance.
