public class RecordableBranchGroup

extends javax.media.j3d.BranchGroup

This class is necessary to detect when children of this node need to have a Canvas3D to synchronize with. If this is true, it is the responsiblity of another object to call setCanvas with the argument consisting of a RecordableCanvas3D.

This calss is used to grab frames from the RecordableCanvas3D without the behaviors (which are handed back in this class) updating the Canvas multiple times between the image dump of the RecordableCanvas3D.
