Detailed DescriptionThe SoListenerDopplerElement holds the doppler velocity and factor of the current listener. The dopplerVelocity and dopplerFactor is set by SoListener nodes during audio rendering. The SoListenerDopplerElement 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
SoListenerDopplerElement::~SoListenerDopplerElement (void) [protected], [virtual]The destructor.
Member Function Documentation
void * SoListenerDopplerElement::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 SoListenerDopplerElement::initClass (void) [static]This static method initializes static data for the SoListenerDopplerElement class. Referenced by SoElement::initElements().
void SoListenerDopplerElement::init (SoState * state) [virtual]Initializes the element to it's default value. The default value for the velocity is (0.0f, 0.0f, 0.0f), in other words, the listener is not moving. The default value for the dopplerFactor is 0.0f, in other words, doppler effect is disabled.
Reimplemented from SoReplacedElement. References dopplerFactor, dopplerVelocity, and SoReplacedElement::init().
void SoListenerDopplerElement::setDopplerVelocity (SoState *const state, SoNode *const node, const SbVec3f & velocity) [static]Sets the current listener's doppler velocity. References dopplerVelocity, and SoElement::getElement(). Referenced by SoListener::audioRender().
void SoListenerDopplerElement::setDopplerFactor (SoState *const state, SoNode *const node, float factor) [static]Sets the current listener's doppler factor. References dopplerFactor, and SoElement::getElement(). Referenced by SoListener::audioRender().
Member Data Documentation
SoListenerDopplerElement::dopplerVelocity [protected]The doppler velocity of the listener. It is the application programmer's responsibility to set this value. Coin does not update this value automatically based on changes in a listener's position. Referenced by getDopplerVelocity(), init(), and setDopplerVelocity().
SoListenerDopplerElement::dopplerFactor [protected]The amount of doppler effect applied to the listener. The normal range would be [0.0f to 1.0f], where 0.0f is default and disable all doppler effects. Referenced by getDopplerFactor(), init(), and setDopplerFactor().
