摘要
参数定义在矩形域与三角域上的De Boor递推算法在曲面造型中得到了广泛的应用,该文介绍了矩形域与三角域上的De Boor递推算法,并研究了在控制点存在扰动与计算过程存在舍入误差的情况下对曲面计算的影响.
De Boor algorithm is widely used in the computer modeling system. This paper gives a instruction of the De Boor algorithm on the area of interval and triangle, and gives an analysis on when there is error in the control points and in the process of the computing, and how would they affect the final results.
