摘要
提出了一种以二维及三维离散点的坐标值代替函数来描述二维及三维曲线的方法，并给出了这种数值曲线生成的叠代算法，该方法以差分替代导数，直接生成曲线上点的坐标。
A method that describes 2D and 3D curves with 2D and 3D discrete points instead of the functions is presented. The algorithm of generating the numerical curves is given. Using the algorithm based on substituting difference for derived function, the points, coordinate values on the curves can be created directly without spline functions.
