Class SceneGraphPathObserver

java.lang.Object

de.jreality.scene.SceneGraphPathObserver

All Implemented Interfaces:

AppearanceListener, SceneGraphComponentListener, TransformationListener, EventListener

public class SceneGraphPathObserver
extends Object
implements AppearanceListener, TransformationListener, SceneGraphComponentListener

This class observes the given path for changes of the resulting path matrix/effective appearance. Note: this class makes a private copy of the path and therefore doesn't care about changes of the path itself! If the observed path changes, call setPath(myPath) to observe the changed path. TODO: add listeners to changes other than transformation or appearance
