## flyAround
可以使用earth.camera.flyAround来操作。
比如这样：
`earth.camera.flyAround([2.1206125026580582,0.545178729438238,15], 3000, [0, -Math.PI / 5, 0], 0, 3.14/50); `

## 示例
效果参见数字城市示例：http://earthsdk.com/v/last/Apps/Examples/earth-digitalCity.html

## 取消操作
如果需要取消默认的双击旋转事件，可以使用这个方法
`earth.czm.viewer.screenSpaceEventHandler.removeInputAction(Cesium.ScreenSpaceEventType.LEFT_DOUBLE_CLICK);`

## 左键双击自定义
添加新方法可以这样：
```
earth.czm.viewer.screenSpaceEventHandler.setInputAction(event => {
// 以下代码根据需要自行修改
const pp = Cesium.xbsjPickPosition(viewer.scene, event.position, scratchCartesian);
if (pp) {
Cesium.xbsjFlyAround(viewer.camera, pp);
}
}, Cesium.ScreenSpaceEventType.LEFT_DOUBLE_CLICK);
```

Start by reading the issue's references to earth.camera.flyAround, screenSpaceEventHandler, and Cesium.ScreenSpaceEventType.LEFT_DOUBLE_CLICK. Determine whether the requested customization is still needed beyond the documented cancellation and replacement handlers; done would require a specific, agreed customization scope and a corresponding example or implementation path.
