摘要
对计算机辅助几何造型中的B啨ｚｉｅｒ曲线的调配函数进行探究 ,利用Friedman的URN模型构造出带有参数的调配函数 ,用其生成拟B啨ｚｉｅｒ曲线 ,这种新曲线可以对数据点进行光顺逼近。利用最小二乘法和非线性泛函的极小值优化计算 ,得到最优的光顺逼近曲线。
In this paper,blending functions and their applications are discussed.Through making use of Friedman's URN modeling, we constructed blending functions to achieve a new quasi-Bézier curve that can be used to fair-approximate to data points of plane. By using of the technique of least square approximation and minimizing a non-linear functional ,we get a fairing -approximation curve.
