[JAVA3D] 3D scene serialization problem

[Andrei Karii]

Hi All ! , What You think about how is possible  to save dynamically content of 3D scenes  as BranchGroup with all its children with their  current values of them fields  into the file  and then  to read it from   file  and  to load  into scene  on-fly  by add and replace BranchGraph  methods of Locale object ?    When i try write BranchGroup or ColorCube to ObjectOutputStream as :      BranchGroup scene = new BranchGroup();        scene.addChild(new ColorCube(0.1));  try{   FileOutputStream fs = new FileOutputStream("scene.serial");     ObjectOutputStream os = new ObjectOutputStream(fs);        os.writeObject(scene);  // or   os.writeObject(new ColorCube(0.1));                      os.flush();     }catch(Exception e){    System.out.println ("from writing scene: \n"+e.toString());    }     then see at runtime : from writing scene: java.io.NotSerializableException: javax.media.j3d.BranchGroup (or  ColorCube)   So,I look for any ideas of how to save and read scene objects into and from file.   May be exists some classes for this ? Or some native code ?   How i think ,it may be applied in games and 3d-editors or somewhere else.   Thank for attention , Andrei Karii .
