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 its 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] Destructor. Member Function Documentation SoType SoListenerPositionElement::getClassTypeId (void ) [static] This static method returns the SoType object associated with objects of this class. int SoListenerPositionElement::getClassStackIndex (void ) [static] This static method returns the state stack index for the class. 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. Creates a new instance of the class type corresponding to the SoType object. void SoListenerPositionElement::initClass (void ) [static] Initialize relevant common data for all instances, like the type system. void SoListenerPositionElement::init (SoState * state) [virtual] Initializes the element to its default value. The default value for the position is (0.0, 0.0, 0.0) and the default value for the setByListener flag is FALSE. Reimplemented from SoReplacedElement. 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. 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 void SoListenerPositionElement::print (FILE * file) const [virtual] Prints contents of element (not implemented). Reimplemented from SoReplacedElement. Member Data Documentation SbVec3f SoListenerPositionElement::position [protected] The position of the listener in world space. Can be set by the SoListener class or the SoCamera class. Author Generated automatically by Doxygen for Coin from the source code. Version 4.0.10 Tue Jun 23 2026 23:48:38 SoListenerPositionElement(3)
