Detailed Description

The SoListenerPositionElement holds the position of the current listener.

This position is set by SoListener nodes and SoCamera Nodes during audio rendering. When a SoListener is visited by the SoAudioRenderAction, it will add a new SoListenerPositionElement to the state, holding its position and with the setbylistener flag set. When a SoCamera is visited by SoAudioRenderAction, it will add a new SoListenerPositionElement only if there are no previous elements with the setbylistener flag set.

The SoListenerPositionElement 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

◆ ~SoListenerPositionElement()

SoListenerPositionElement::~SoListenerPositionElement ( void  )
protectedvirtual

The destructor.

Member Function Documentation

◆ createInstance()

void * SoListenerPositionElement::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.

◆ initClass()

void SoListenerPositionElement::initClass ( void  )
static

This static method initializes static data for the SoListenerPositionElement class.

◆ init()

void SoListenerPositionElement::init ( SoState state)
virtual

Initializes the element to its default value. The default value for the position is (0.0, 0.0, 0.0) and the default value for the setByListener flag is FALSE.

Reimplemented from SoReplacedElement.

◆ set()

void SoListenerPositionElement::set ( SoState *const  state,
SoNode *const  node,
const SbVec3f position,
SbBool  setbylistener 
)
static

Sets the current listener position, and indicates if it was set by a SoListener node or a SoCamera node.

◆ isSetByListener()

SbBool SoListenerPositionElement::isSetByListener ( SoState *const  state)
static

Returns TRUE if the position was set by a SoListener node, and FALSE if it was set by a SoCamera node

Member Data Documentation

◆ position

SoListenerPositionElement::position
protected

The position of the listener in world space. Can be set by the SoListener class or the SoCamera class.
