SoListenerDopplerElement Class Reference
[Elements (mostly for internal use)]

#include <Inventor/elements/SoListenerDopplerElement.h>

Inheritance diagram for SoListenerDopplerElement:

SoReplacedElement SoElement List of all members.

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   )  [protected, virtual]
 

The destructor.


Member Function Documentation

void SoListenerDopplerElement::initClass void   )  [static]
 

This static method initializes static data for the SoListenerDopplerElement class.

Reimplemented from SoReplacedElement.

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.
