圆弧样条曲线与小弧处理

Arc Spline and Arclet Processing

  • 摘要: 已知2点平面坐标及切线方向,可以在其间构造1对凹凸性相同的光滑圆弧。本文介绍了一种新的样条曲线——圆弧样条,在解求其平行线时可能发生的"小弧"现象,需专门程序处理。

     

    Abstract: This paper presents a new spline——arc spline.It tubes two arcs connecting adjacent points among a sampled series,with known tangent at each sampled point. The calculation for the parallel,the curve length and the segmenting points coordinates are simple,thus making map symbal generation simplexed.When"arclet"occurs,some specinl processing must be taken.
