Example
//构造地图对象
var map = new GeoGlobe.Map({
    style: Cfg.style,
    container: 'map',
    zoom: 16,
    bearing: -138.23,
	pitch: 57.50,
	units: "degrees",
    center: [114.20509630753577, 30.776055193053764]
});
//构造THREE可视化图层
var threebox = new GeoGlobe.Visuals.Three();
//添加到地图中
threebox.addTo(map);
//构造符号图层，汽车模型 ，glTF格式
var symbolLayer2 = new GeoGlobe.Visuals.Three.SymbolLayer({
	id: '3D marker 2',
	data: [
		{"type": "Feature","properties": {"id": 10001, "name": "五号汽车","height": 0 }, "geometry": {"type": "Point","coordinates": [114.20257245367856, 30.773372078561778]}}
	],
	visible: true,
	opacity: 1,
	scale: 20,
	modelURL: "../../data/CesiumMilkTruck/CesiumMilkTruck.gltf",
	getGeometry: function(geometry, data){
	    geometry.rotateX((90/360)*2*Math.PI);
	    geometry.rotateY((-90/360)*2*Math.PI);
	    return geometry
	},
	getLoader: function(){
		return new THREE.GLTFLoader() //glTF versions >= 2.0
	}
})
//添加到THREE图层
symbolLayer2.addTo(threebox);
//绘制
threebox.render();
