Detailed DescriptionThe SoListenerPositionElement holds the position of the current listener. This position is set by SoListener nodes and SoCamera Nodes during audio rendering. When a SoListener is visited by the SoAudioRenderAction, it will add a new SoListenerPositionElement to the state, holding it's position and with the setbylistener flag set. When a SoCamera is visited by SoAudioRenderAction, it will add a new SoListenerPositionElement only if there are no previous elements with the setbylistener flag set. The SoListenerPositionElement 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
SoListenerPositionElement::~SoListenerPositionElement (void) [protected], [virtual]The destructor.
Member Function Documentation
void * SoListenerPositionElement::createInstance (void) [static]This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
void SoListenerPositionElement::initClass (void) [static]This static method initializes static data for the SoListenerPositionElement class. Referenced by SoElement::initElements().
void SoListenerPositionElement::init (SoState * state) [virtual]Initializes the element to it's default value. The default value for the position is (0.0f, 0.0f, 0.0f) and the default value for the setByListener flag is FALSE. Reimplemented from SoReplacedElement. References SoReplacedElement::init(), and position.
void SoListenerPositionElement::set (SoState *const state, SoNode *const node, const SbVec3f & position, SbBool setbylistener) [static]Sets the current listener position, and indicates if it was set by a SoListener node or a SoCamera node. References SoElement::getElement(), and position. Referenced by SoListener::audioRender(), and SoCamera::audioRender().
SbBool SoListenerPositionElement::isSetByListener (SoState *const state) [static]Returns TRUE if the position was set by a SoListener node, and FALSE if it was set by a SoCamera node References SoElement::getConstElement(). Referenced by SoCamera::audioRender().
Member Data Documentation
SoListenerPositionElement::position [protected]The position of the listener in world space. Can be set by the SoListener class or the SoCamera class. Referenced by get(), init(), and set().
