不规则地图边界曲线的生成

Generation of Irregular Boundary Curves on Map

摘要: 将有限的边界测量点，作为控制地图曲线大致形状的控制顶点，有关顶点的连线构成了反映地图大致形态的边形，用随机函数法可实现各边的曲化，采用本文提出的箭头法，避免顶点处的过大波动及其可能发生的顶点附近的曲线交叉。

Abstract: The limited boundary measuring points are used for the vertexes which controlthe map shape. The joining of these vertexes is composed of a polygon that can unfold theapproximate shape of the map.The curved edges are acquired by random function and the arrowhead way is able to avoid the bigger undulating near the vertex and the crossing of thecurves.
