The SoListenerGainElement class stores the SoListener gain during a scene graph traversal.
This gain is set by SoListener nodes during audio rendering. The SoListenerGainElement 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.
SoListenerGainElement::~SoListenerGainElement | ( | void | ) | [protected, virtual] |
The destructor.
void SoListenerGainElement::initClass | ( | void | ) | [static] |
Initialize relevant common data for all instances, like the type system.
Reimplemented from SoFloatElement.
void SoListenerGainElement::init | ( | SoState * | state | ) | [virtual] |
This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState objects.
Reimplemented from SoFloatElement.
References SoFloatElement::data, and SoFloatElement::init().
void SoListenerGainElement::set | ( | SoState *const | state, |
SoNode *const | node, | ||
const float | gain | ||

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
References set().
float SoListenerGainElement::get | ( | SoState *const | state | ) | [static] |
Returns the element value.
