writer.writeBranchGraph(bg);
writer.close();
}catch (Exception exc){}
}
public void load() {
SimpleUniverse su = null;
try {
SceneGraphFileReader reader = new SceneGraphFileReader(new File("library.j3d"));
su = (SimpleUniverse)reader.readUniverse(true);
reader.close();
}catch (Exception exc) {System.out.println(exc); }
Frame f = new Frame();
f.setLayout(new BorderLayout());
f.setSize(300,300);
f.show();
Canvas3D canvas3D = su.getCanvas();
