Detailed Description

Basic EventVisitor implementation for animating a scene.

This visitor traverses the scene graph, calling each nodes appCallback if it exists.

virtual void osgGA::EventVisitor::reset (  )  [virtual]

Method to call to reset visitor.

Useful if your visitor accumulates state during a traversal, and you plan to reuse the visitor. To flush that state for the next traversal: call reset() prior to each traversal.

Reimplemented from osg::NodeVisitor.

virtual void osgGA::EventVisitor::apply ( osg::Node node  )  [inline, virtual]

During traversal each type of node calls its callbacks and its children traversed.
