var position = Cesium.Cartesian3.fromDegrees(obj.position[0], obj.position[1], obj.position[2]); //数据加载位置
	var heading = Cesium.Math.toRadians(obj.heading);
	var pitch = Cesium.Math.toRadians(obj.pitch);
	var roll = Cesium.Math.toRadians(obj.roll);
	var hpRoll = new Cesium.HeadingPitchRoll(heading, pitch, roll);
	var converter = Cesium.Transforms.eastNorthUpToFixedFrame;
	var modelMatrix = Cesium.Transforms.headingPitchRollToFixedFrame(position, hpRoll, Cesium.Ellipsoid.WGS84, converter);
	//添加三维模型
	var tileset = this.viewer.scene.primitives.add(
		new Cesium.Cesium3DTileset({
			url: obj.url, //模型数据url
			show: obj.show, //确定是否显示图块集
			asset: {

			},
		})
	);
	tileset.readyPromise.then(function () {
		//请求模型后执行
		tileset._root.transform = modelMatrix; //模型位置
		tileset.asset.id = obj.id;
		Object.assign(tileset.asset, obj.option);
	}).otherwise(function (error) {

	return tileset;
