const handler = new Cesium.ScreenSpaceEventHandler(viewer.scene.canvas);

添加model

    handler.setInputAction((movement) => {//鼠标左键事件，点击地图，在点击位置添加模型
      var cartesian = viewer.scene.globe.pick(viewer.camera.getPickRay(movement.position), viewer.scene);//获取地形上的点
      const newHeading = Cesium.Math.toRadians(0); //初始heading值赋0
      const newPitch = Cesium.Math.toRadians(0);
      const newRoll = Cesium.Math.toRadians(0);
      const headingPitchRoll = new Cesium.HeadingPitchRoll(newHeading, newPitch, newRoll);
      const modelMatrix = Cesium.Transforms.headingPitchRollToFixedFrame(cartesian, headingPitchRoll, Cesium.Ellipsoid.WGS84, Cesium.Transforms.eastNorthUpToFixedFrame, new Cesium.Matrix4());
      viewer.scene.primitives.add(Cesium.Model.fromGltf({
        url, // 模型地址
        modelMatrix,
      }));
    }, Cesium.ScreenSpaceEventType.LEFT_CLICK);
