Here is the method for compiling the branchgroup returned from createView()
method and add to locale:
public JEngine(String vu){
Frame frame = new Frame(vu);
frame.setLayout(new BorderLayout());
frame.setUndecorated(true);
frame.setBackground(Color.BLACK);
GraphicsEnvironment ge =
GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice d = ge.getDefaultScreenDevice();
if(d.isFullScreenSupported())
d.setFullScreenWindow(frame);
GraphicsConfiguration[] gc = d.getConfigurations();
GraphicsConfigTemplate3D gct = new
GraphicsConfigTemplate3D();
GraphicsConfiguration graphics =
gct.getBestConfiguration(gc);
if(gct.isGraphicsConfigSupported(graphics))
System.out.println("Graphics Device Supported");
else{
System.out.println("Graphics Device NOT Supported");
System.exit(1);
}
Canvas3D c3d = new Canvas3D(graphics);
Button button = new Button("Exit");
button.addActionListener(new ActionEvents());
frame.add(c3d, BorderLayout.CENTER);
frame.add(button, BorderLayout.SOUTH);
frame.addKeyListener(new KeyEvents());
BranchGroup bg = createBox();
bg.compile();
VirtualUniverse u = new VirtualUniverse();
Locale locale = new Locale(u);
BranchGroup bg2 = createView(c3d);
bg2.compile();
locale.addBranchGraph(bg);
locale.addBranchGraph(bg2);
frame.show();
}
I followed the scene graph structure, compile the BranchGroup returned from
createView() and add to locale, and locale is attached to the Virtual
Universe. I don't know why the KeyNavigatorBehavior doesn't work that way.
Thanks for replying.
