public class MathCameraListener

extends MathListener

implements PvCameraListenerIf, java.lang.Runnable

Listener to receive events of camera in display to invoke Mathematica commands. The camera event contains information about the current state of the camera such as position, viewing direction and projection mode.

The event does not contain pick information of the geometry, see MathPickListener.
