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...

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.

The destructor.
|
static |
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
|
static |
This static method initializes static data for the SoListenerOrientationElement class.
Referenced by SoElement::initElements().
|
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.

static |
Sets the current listener orientation, and indicates if it was set by a SoListener node or a SoCamera node.
References SoElement::getElement(), and orientation.
Referenced by SoListener::audioRender(), and SoCamera::audioRender().
|
static |
Returns TRUE if the orientation was set by a SoListener node, and FALSE if it was set by a SoCamera node

protected |
The orientation of the listener. Can be set by the SoListener class or the SoCamera class.
