| 摘 要： | 在微机地理制图中,张力样条插值法是一种有效实现光滑曲线的方法.它既能保证曲线光滑又能避免曲线相交.本文采用张力样条算法并用VC＋＋实现曲线的光滑,同时还可以动态改变曲线张力系数σ值,以使得节点间的曲线为最短,这样既能消除可能出现的多余拐点,又能保持曲线的光滑性,能够满足实际工作中的需要.

| Abstract: | In the computer geographic mapping,the tension spline interpolation is an effective method to realize the smoothing curve.It can prevent the curve from being crossing so as to make it smooth.This paper realizes smoothing curve with tension spline calculation and with VC++.At the same time,itchanges the tension coefficient value of curve in order to make curve of node the shortest.In this way,it can not only remove the surplus inflexion,but also can keep the curve smooth. |
