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.

Since

Coin 2.0

Constructor & Destructor Documentation

SoListenerDopplerElement::~SoListenerDopplerElement ( void  )

protectedvirtual

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.
