摘要
文章基于数据采样插补算法的主要思路,提出了一种新的圆弧插补算法并加以实现。改进的算法在求每一个插补点时没有近似计算,故径向误差为零;大量的计算在编程时放在预处理阶段进行,故执行速度快。文章给出了程序流程图,并用Visual C++语言编程实现,文中给出了第一象限圆弧的插补源程序。对于空间圆弧的插补点计算,则是利用坐标变换的方法,但关键仍是要先求出平面上插补点的坐标。
A new circle interpolation algorithm is given and come true,in this paper basing a method of data sampling law.There is not approximate calculation in this algorithm when every interpolation coordinate is sought,so radial error is zero;a lot of calculations are put in the preparation stage,so speed of execution is high. Program flow chart is given in this paper,and the algorithm is come true with Visual C ＋＋ programming language.The programe of first quadrant arc is given.About the calculation of space arc interpolation coordinate,we use the coordinate transformation method but the key is that plane interpolation coordinate is made.
