Example
//构造地图对象
var map = new GeoGlobe.Map({
    style: Cfg.style,
    container: 'map',
    zoom: 18,
    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();
//绑定鼠标点击事件
threebox.on('overlayerclick', function(e){
    var xyz = threebox.unprojectFromWorld(e.param.pickedInfos[0].point);
    alert(e.param.info.userData.attributes.OriginalData.properties.name + '\n经纬度及高程:' + xyz);
});
//绑定鼠标移动事件
threebox.on('overlayerhover', function(e){
    console.info(e);
});
//添加到地图中
threebox.addTo(map);
//构造文本图层
