The SoListenerOrientationElement holds the orientation of the current listener.

This orientation is set by SoListener nodes and SoCamera Nodes during audio rendering. When a SoListener is visited by the SoAudioRenderAction, it will add a new SoListenerOrientationElement to the state, holding its orientation and with the setbylistener flag set. When a SoCamera is visited by SoAudioRenderAction, it will add a new SoListenerOrientationElement only if there are no previous elements with the setbylistener flag set.

The SoListenerOrientationElement is used when the SoVRMLSound nodes render themselves.

Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Destructor.

SoType SoListenerOrientationElement::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class.

This static method returns the state stack index for the class.

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.


Creates a new instance of the class type corresponding to the SoType object.

Initialize relevant common data for all instances, like the type system.

Initializes the element to its default value. The default value for the orientation is (0.0, 0.0, 1.0, 0.0) and the default value for the setByListener flag is FALSE.

Reimplemented from SoReplacedElement.

Sets the current listener orientation, and indicates if it was set by a SoListener node or a SoCamera node.

Returns TRUE if the orientation was set by a SoListener node, and FALSE if it was set by a SoCamera node

Prints the contents of the element (unimplemented)

Reimplemented from SoReplacedElement.

SbRotation SoListenerOrientationElement::orientation [protected]

The orientation of the listener. Can be set by the SoListener class or the SoCamera class.
