Getting a mouse click position on the map

I'm new to Cesium, and I am trying to allow the user to select a location on the map (mouse click), or use the mouse to specify a region of interest (e.g. rectangle or circle). I see how to get mouse events, but the coordinates are in screen space. How can I convert these into lat,lon values? The goal is to use this user input to do things like retrieve query results for that geographic location.

Thanks for any pointers.

Check out the Picking Sandcastle example. Just mouse over the globe to see the lat/lon.


I have the same requirement but the link does not work. Does anyone have another sample?

Thanks a lot~
