Detailed DescriptionThe 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

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

---

Member Function Documentation

---

void * SoListenerOrientationElement::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 SoListenerOrientationElement::initClass (void) [static]This static method initializes static data for the SoListenerOrientationElement class​.

---

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​.

---

void SoListenerOrientationElement::set (SoState *const state, SoNode *const node, const SbRotation & orientation, SbBool setbylistener) [static]Sets the current listener orientation, and indicates if it was set by a SoListener node or a SoCamera node​.

---

SbBool SoListenerOrientationElement::isSetByListener (SoState *const state) [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​.
