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();
