vue中cesium添加实例模型

let fanModel = {
     uri: 'model3D/fan.glb', // glb实例模型
     height: 85,
     scaling: 160.05,
     heading: 90,
     pitch: 90,
     roll: 0
  }
let position = Cesium.Cartesian3.fromDegrees(longitude, latitude, fanModel.height)
let fanEntity = new Cesium.Entity({
      id: 'fan' + fan.fanId,
      show: true,
      position: position,
      orientation: Cesium.Transforms.headingPitchRollQuaternion(
          position,
          new Cesium.HeadingPitchRoll(
            Cesium.Math.toRadians(fanModel.heading), // heading 船首向
            Cesium.Math.toRadians(fanModel.pitch), // pitch   左右翻转
            Cesium.Math.toRadians(fanModel.roll) // roll     前后翻转
          )
       ),
       model: {

          scale: fanModel.scaling,
          runAnimations: true,
          color: Cesium.Color.RED
       },
       label: {
