LineLayer

GeoGlobe.Visuals.Three. LineLayer

new LineLayer()

三维线图层
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);
 //构造线图层
 var lineLayer = new GeoGlobe.Visuals.Three.LineLayer({
	id: '3D line',
    data: [],
    visible: true
});
 //添加到THREE图层
 lineLayer.addTo(threebox);
 //绘制
 threebox.render();
