摘要
本文给出了k(k≥2)阶带形状参数指数多项式的均匀B样条模型。该类模型具有很多与B样条模型相同的性质,并且具有一个可调节的形状参数。由该模型构造的曲线,通过改变形状参数的取值,可以调整曲线接近其控制多边形的程度。该模型可以应用于CAD/CAM领域,作为几何造型一种新的有效模型。
A new model of k（k≥2）order exponential uniform B-spline with shape parameter is giverL Most of its properties similar to those of the B-spline model , and also it has a shape parameter. The spline curves which are constructed by the exponential uniform B-spline with shape parameter can adjust the curve＇ s shape and the degrees between the curve and its control polygon with changing the parameter value. The new model can be applied to the field of CAD/CAM.
