Inheritance diagram for SoListenerDopplerElement:
Public Methods | |
virtual void | init (SoState *state) |
virtual void | print (FILE *file) const |
Prints the contents of the element (unimplemented). | |
Static Public Methods | |
void | initClass (void) |
void | setDopplerVelocity (SoState *const state, SoNode *const node, const SbVec3f &velocity) |
void | setDopplerFactor (SoState *const state, SoNode *const node, float factor) |
const SbVec3f & | getDopplerVelocity (SoState *const state) |
Returns the current listener's doppler velocity. | |
float | getDopplerFactor (SoState *const state) |
Returns the current listener's doppler factor. | |
Protected Methods | |
virtual | ~SoListenerDopplerElement () |
Protected Attributes | |
SbVec3f | dopplerVelocity |
float | dopplerFactor |
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.

The destructor. |
|
This static method initializes static data for the SoListenerDopplerElement class. Reimplemented from SoReplacedElement. |
|
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. |
|
Sets the current listener's doppler velocity. |
|
Sets the current listener's doppler factor. |
|
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. |
|
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. |
