Detailed Description

A node that updates the transformation of the listener. Should traversed before any SoundNode nodes.

This class updates the internal state of the osgAL::SoundManager during cull traversal from the current modelView matrix. The cull traversal for this node should be called after any changes are made to the SoundManager (added SoundState events or such).

virtual const char* osgAL::SoundRoot::className (    )  const [inline, virtual]

float osgAL::SoundRoot::getListenerUpdateFrequency (    )  const [inline]

Return the frequency by which the orientation and position of the listener is updated

bool osgAL::SoundRoot::getUpdateEnable (    )  const [inline]

virtual bool osgAL::SoundRoot::isSameKindAs (  const osg::Object *    obj )  const [inline, virtual]

virtual const char* osgAL::SoundRoot::libraryName (    )  const [inline, virtual]

SoundRoot& osgAL::SoundRoot::operator= (  const SoundRoot &    node )  [protected]

Assignment operator.

void osgAL::SoundRoot::setListenerUpdateFrequency (  float    f )  [inline]

Set the frequency with which the orientation and position of the listener is updated. This is to avoid calling OpenAL++ listener update to often (click under linux) ams f - Frequency of update.

void osgAL::SoundRoot::setUpdateEnable (  bool    flag )  [inline]

void osgAL::SoundRoot::traverse (  osg::NodeVisitor &    nv )

Executed during traversal of the scenegraph. If the NodeVisitor is a CullVisitor the orientation/position and velocity of the listener is updated.
