Implements ShapeOwner interface.

This is called by the sceene renderer in the viewer core before non transient, full redraws, right before the scene is validated. It this ShapeNode has set bViewpointDependant to true, and the viewpoint has changed, its geometry is invalidated. This is an easy way to cause a geometry change in response to the viewpoint.

Specified by:

                              Selector selector)

Called when mouse is moved over this ShapeNode in viewport. The default implementation is a no-op. The Selector calls then processMouseExited (with no processMouseMoved first) when mouse leaves shape, or processMouseEntered then processMouseMoved when mouse enters shape. It also calls processMouseMoved every time is sences mouse has moved inside the same shape.

processMouseEntered

public void processMouseEntered(harmonic.viewer3D.event.ViewportMouseEvent e,

                                Selector selector)

                                 Selector selector)

public void processMouseDragged(harmonic.viewer3D.event.ViewportMouseEvent e,
                                Selector selector)

Called when mouse is dragged over this ShapeNode in viewport. The default implementation calles upon the object selector to handle the event. This function will be called for the object that was under the mouse cursor when the drag *started*, so the object may not be under the mouse anymore if the mouse has been dragged off. This convention follows the window drag event model.
