new PolygonLayer()
多边形图层
Example
//构造地图对象
var map = new GeoGlobe.Map({
style: Cfg.style,
container: 'map',
zoom: 16,
bearing: -47,
pitch: 45,
units: "degrees",
center: [114.26734490525155, 30.594607628267966]
});
//构造THREE可视化图层
var threebox = new GeoGlobe.Visuals.Three();
//添加到地图中
threebox.addTo(map);
//构造点图层
var polygonLayer = new GeoGlobe.Visuals.Three.PolygonLayer({
id: '3D point',
data: [{"type":"Feature","properties":{"name": "一号多边形", color: "skyblue"},"geometry":{"type":"Polygon","coordinates":[]}},
{"type":"Feature","properties":{"name": "二号多边形", color: "rgb(255, 120, 0)"},"geometry":{"type":"Polygon","coordinates":[]}}],
visible: true,
opacity: 1
});
//添加到THREE图层
polygonLayer.addTo(threebox);
//绘制
threebox.render();
