| 摘 要： | 提出了带形状参数的n次Wang-Ball调配函数，它是n次Wang-Ball基函数的扩展，它具有与n次Wang-Ball基函数相似的性质。基于给出的调配函数，构造了带形状参数的多项式曲线。参数λ具有明确的几何意义，当λ增大时，曲线将逼近于控制多边形，当λ=0时，即退化为n次Wang-Ball调配函数，它为曲线设计提供了一种有效的方法。

| Abstract: | In this paper,a class of blending functions of n degrees is presented.It is the extension of the Wang-Ball functions of n degrees.It has the similar properties with the n-degree Wang-Ball curves.Based on the blending functions,the polynomial curves with a shape parameter are constructed.By changing the value of the shape parameters,the approaching degree of the curves to their control polygons can be adjusted.These curves converge to n-degree Wang-Ball curves then.The presented method is useful for the curv... |
