摘要
本文提出了多数曲线近似弧长参数化的一种三角函数方法．参数曲线的弧长函数用三角函数作保单调插值，得到的近似弧长参数化曲线插值原参数曲线上的一组点，且曲线在这组点上对应的弧长精确等于它对应的参数值．
This paper presents an interpolation for mearly are-length parameterization based on thetrigonometric function.The arc-length function of parametric curve is monotonic increasing ,the monotonitypreserving approximation function based on trigonometric function for the arc-length function is derived.Theresulting nearly arc -length parametrization curve interpolates a set of points of original surre, and the arc-length of the curve is accurate at each of this set of points.
