SoListenerDopplerElement.3coin3 man page

SoListenerDopplerElement — The 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.

Detailed Description

The 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.

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.

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.

void SoListenerDopplerElement::setDopplerVelocity (SoState *const state, SoNode *const node, const SbVec3f & velocity) [static]

Sets the current listener's doppler velocity.

void SoListenerDopplerElement::setDopplerFactor (SoState *const state, SoNode *const node, float factor) [static]

Sets the current listener's doppler factor.

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.

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.
