Parameters
distanceFromPOI
The distance from the camera to the point on the terrain that the camera center is looking at.
Flags
Reserved. Always pass 0 (zero).
Exceptions
See: HRESULT Return Values for a list of possible values returned by the HRESULT.
Remarks
The outcome of the zoomTo operation depends on the current distance between the camera and the camera’s point of interest (POI) at the center of the view. If distanceFromPOI is bigger than the current distance between the camera and the point of interest, the camera moves backwards. If it is smaller, it moves forward.
