SoListenerOrientationElement Class Reference

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 it's 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. More...

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 it's 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.

Since:
Coin 2.0

Member Function Documentation

void SoListenerOrientationElement::initClass ( void  ) [static]

This static method initializes static data for the SoListenerOrientationElement class.

Reimplemented from SoReplacedElement.

void SoListenerOrientationElement::init ( SoState state) [virtual]

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

Reimplemented from SoReplacedElement.

References SoReplacedElement::init(), and orientation.

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.

References SoElement::classStackIndex, SoElement::getElement(), and orientation.

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

References SoElement::classStackIndex, and SoElement::getConstElement().

Referenced by SoCamera::audioRender().


Member Data Documentation
