摘要
文章给出了带形状参数λ的二次非均匀双曲B样条曲线,可以通过改变λ值来调节曲线形状,从而为曲线表示提供了一种新方法。此外,该曲线不仅具有一般多项式B样条曲线的诸多优良性质,还可以精确地表示双曲线。文章给出具体例子说明通过改变λ的值来反映其对图形的影响。
.A kind of quadratic non-uniform hyperbolic B-spline curve with a shape parameter λ is pres- ented. The shape of the curve can be manipulated by changing the value of the parameter λ, thus con- structing a simple method to represent planar curves. This kind of curve not only possesses the most advantages of quadratic polynomial Prspline curves, but also represents hyperbolas accurately. The numerical examples are given to demonstrate the effect of the parameter λ on the graph by changing the value of it.
