其次 ,基于参数速度的 L egendre多项式逼近和插值区间端点的 Jacobi多项式逼近,导出了保持法平移方向的两种代数方式的等距有理逼近算法。

The basic idea is as follows: first, a kind of plane α-B-spline interpolation curve with a shape control parameter a is constructed; then, by converting the first derivatives of the curve into Bernstein polynomial, the positive conditions of Bernstein polynomial can be used to get the necessary and sufficie nt conditions for the monotonicity of α-B-spline interpolation curves, i.e., the range of the parameter a. Therefore, monotone-preserving interpolating curves can be obtained succinctly.

其基本思想是:首先构造带有形状可调参数的一类平面(-B样条插值曲线,再把其一阶导的两个分量分别转化为Bernstein多项式,从而利用Bernstein多项式的正性条件,得到此曲线为单调的充要条件,即形状参数的取值范围,简单、快捷地实现此参数样条曲线的保单调插值。
