Folks,

Where can we get events when a user zooms or rotates the view?

Thanks

Ian

Hello Ian,

There are two events on Camera to see when the camera movement starts and ends. See [Camera.moveStart](http://cesiumjs.org/Cesium/Build/Documentation/Camera.html#moveStart) and [Camera.moveEnd](http://cesiumjs.org/Cesium/Build/Documentation/Camera.html#moveEnd)

Also see this demo, which uses the moveStart and moveEnd events: [http://analyticalgraphicsinc.github.io/cesium-google-earth-examples/examples/viewchangeEvent.html](http://analyticalgraphicsinc.github.io/cesium-google-earth-examples/examples/viewchangeEvent.html)

Best,

Hannah

Hannah,

Thanks, let us take a look at these.

We also want to be able to disable all user input (zoom, pan, rotate) at certain times, say when we are replaying a specific sequence. Is there a way of easily doing this?

Thanks

Ian

Yes! To disable inputs, set

viewer.scene.screenSpaceCameraController.enableInputs = false;

``

Then you can re-enable it by setting the value back to true.
