提出一种带可变频率的新的样条,称之为ωB样条.它不仅统一了B样条、三角多项式B样条以及双曲多项式B样条,而且能表示更多新的样条模型.ωB样条基定义在由{cosωt,sinωt,1,t,…,tn,…}所张成的空间上,其中ω为频率序列,n为任意非负整数.ωB样条保有B样条的所有优良性质,并且还具有其他有利于自由曲线曲面造型的独特性质. A new spline with variable frequency is proposed, called ωB spline, which not only unifies B-spline, triangular polynomial B-spline and hyperbolic polynomial B-spline, but also can represent more new splines Model. ΩB spline is defined in the space formed by {cosωt, sinωt, 1, t, ..., tn, ...}, where ω is the frequency sequence and n is any non-negative integer. All the good properties of the bar, and also has other unique characteristics conducive to free-form curve and surface modeling.
