voronoi
描述
🌐 Description
接收一组点和一个边界框,并返回一组沃罗诺伊多边形。
🌐 Takes a collection of points and a bounding box, and returns a collection of Voronoi polygons.
使用的 Voronoi 算法来自 d3-voronoi 包。
🌐 The Voronoi algorithim used comes from the d3-voronoi package.
参数
🌐 Parameters
| 名称 | 类型 | 描述 |
|---|---|---|
| points | FeatureCollection<Point> | 用于计算沃罗诺伊多边形的点 |
| options? | Object | 可选参数 (默认 {}) |
| options.bbox? | BBox | 裁剪矩形,按 [minX, minY, maxX, maxY] 顺序 (默认 [-180,-85,180,-85]) |
返回
🌐 Returns
FeatureCollection<Polygon> 一组多边形,每个输入点对应一个
示例
🌐 Examples
const options = {
bbox: [-70, 40, -60, 60],
};
const points = turf.randomPoint(100, options);
const voronoiPolygons = turf.voronoi(points, options);
安装
🌐 Installation
