Detailed Description

The SoListenerOrientationElement holds the orientation of the current listener.

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

The SoListenerOrientationElement 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

◆ ~SoListenerOrientationElement()

SoListenerOrientationElement::~SoListenerOrientationElement ( void )
protectedvirtual

Destructor.

Member Function Documentation

◆ getClassTypeId()

SoType SoListenerOrientationElement::getClassTypeId ( void )
static

This static method returns the SoType object associated with objects of this class.

◆ getClassStackIndex()

int SoListenerOrientationElement::getClassStackIndex ( void )
static

This static method returns the state stack index for the class.

◆ createInstance()

void * SoListenerOrientationElement::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.

Creates a new instance of the class type corresponding to the SoType object.

◆ initClass()

void SoListenerOrientationElement::initClass ( void )
static

Initialize relevant common data for all instances, like the type system.

◆ init()

void SoListenerOrientationElement::init ( SoState * state)
virtual

Initializes the element to its default value. The default value for the orientation is (0.0, 0.0, 1.0, 0.0) and the default value for the setByListener flag is FALSE.

Reimplemented from SoReplacedElement.

◆ set()

void SoListenerOrientationElement::set ( SoState *const state,
SoNode *const node,
const SbRotation & orientation,
SbBool setbylistener )
static

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

◆ isSetByListener()

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

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

◆ print()

void SoListenerOrientationElement::print ( FILE * file) const
virtual

Prints the contents of the element (unimplemented).

Reimplemented from SoReplacedElement.

Member Data Documentation

◆ orientation

SbRotation SoListenerOrientationElement::orientation
protected
