NAME

       SoListenerOrientationElement -

       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 it's 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.

Detailed Description

       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 it's 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.

       Since:
           Coin 2.0

Constructor & Destructor Documentation

   SoListenerOrientationElement::~SoListenerOrientationElement (void) [protected, virtual] The
       destructor.

Member Function Documentation

   void SoListenerOrientationElement::initClass (void) [static] This static method initializes
       static data for the SoListenerOrientationElement class.
       Reimplemented from SoReplacedElement.

   void SoListenerOrientationElement::init (SoState *state) [virtual] Initializes the element to
       it's default value. The default value for the orientation is (0.0f, 0.0f, 1.0f, 0.0f) and
       the default value for the setByListener flag is FALSE.
       Reimplemented from SoReplacedElement.

   SbBool SoListenerOrientationElement::isSetByListener (SoState *conststate) [static] Returns
       TRUE if the orientation was set by a SoListener node, and FALSE if it was set by a
       SoCamera node

Member Data Documentation

   SoListenerOrientationElement::orientation [protected] The orientation of the listener. Can be
       set by the SoListener class or the SoCamera class.
