[Solved] Swapping Globes messes up OrbitBehavior

[zaknixon]

I have an small application that I want to use to swap between flat and round globes. I start off with the default round earth, and I can move the globe with the mouse as usual. When I click a key, it swaps to the flat globe, but my mouse actions are gone. I am using bits and pieces from the FlatWorld example, so I have been through that example exhaustively to figure this out.

Are there any ideas on why the orbit behavior being stopped/removed when swapping flat/round globes ?

BTW: I am utilizing the same enableFlatGlobe(boolean) in the FlatWorldPanel.java file, so the concept of swapping is already solved.

Thank you for any help.

I comment out the setView(..) lines in enableFlatGlobe(bool) method, and the globes still move, albeit not correctly since I am not swapping the orbit behavior based on the globe type. So, from what I can tell, it is an issue with setView(..) and I don't know how I can figure it out...

Any ideas on what I can try next ?

Thanks.

Here is the code I am trying:

(If you comment out the setView methods, you will see the MouseMovements will still work)

public class Test {

	private static boolean isRound = true;
	private static WorldWindowGLCanvas canvas;
    private static Globe roundGlobe;
    private static FlatGlobe flatGlobe;
	
	public static void main(String[] args) throws GLException, IOException{
		
		try{
		
    	Model displayModel = (Model) WorldWind.createConfigurationComponent(AVKey.MODEL_CLASS_NAME);
    	canvas = new WorldWindowGLCanvas();
    	canvas.setModel(displayModel);
    	
    	Globe g = displayModel.getGlobe();
		
		if (g instanceof FlatGlobe)
        {
            flatGlobe = (FlatGlobe)g;
            roundGlobe = new Earth();
        }
        else if(g instanceof Earth)
        {
            flatGlobe = new EarthFlat();
            roundGlobe = canvas.getModel().getGlobe();
        }

    	JFrame frame = new JFrame();
		frame.getContentPane().add(canvas);
		frame.setVisible(true);
		
		canvas.addKeyListener(new KeyListener(){

			public void keyPressed(KeyEvent arg0) {

			}

			public void keyReleased(KeyEvent arg0) {

			}

			public void keyTyped(KeyEvent arg0) {
				isRound = !isRound;
				enableFlatGlobe(isRound);	
			}
			
		});
		
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		}catch(Exception e){
			e.printStackTrace();
		}
		
	}
	
	private static String getProjection()
    {
        return FlatGlobe.PROJECTION_LAT_LON;
    }
    
    public static boolean isFlatGlobe()
    {
        return canvas.getModel().getGlobe() instanceof FlatGlobe;
    }
    
	public static void enableFlatGlobe(boolean flat)
    {
        if(isFlatGlobe() == flat)
            return;

        if(!flat)
        {
            // Switch to round globe
            canvas.getModel().setGlobe(roundGlobe) ;
            // Switch to orbit view and update with current position
            FlatOrbitView flatOrbitView = (FlatOrbitView)canvas.getView();

            orbitView.setHeading(flatOrbitView.getHeading());
            orbitView.setPitch(flatOrbitView.getPitch());
            canvas.setView(orbitView);
            // Change sky layer
            LayerList layers = canvas.getModel().getLayers();
            for(int i = 0; i < layers.size(); i++)
            {
                if(layers.get(i) instanceof SkyColorLayer)
                    layers.set(i, new SkyGradientLayer());
            }
        }
        else
        {
            // Switch to flat globe
        	canvas.getModel().setGlobe(flatGlobe);
            flatGlobe.setProjection(getProjection());
            // Switch to flat view and update with current position
            BasicOrbitView orbitView = (BasicOrbitView)canvas.getView();
            FlatOrbitView flatOrbitView = new FlatOrbitView();
            flatOrbitView.setCenterPosition(orbitView.getCenterPosition());

You example code works as expected for me, i see no issues right away...

[zaknixon]

I am running it on a Macbook Pro, so I wonder if that is the problem....I will try it out on a PC and post the results.

[zaknixon]

Strange thing is that I can run the FlatWorld example on my Macbook Pro and it works beautifully, but executing that code doesn't work. Personally, I don't see any major differences between the two.

[zaknixon]

This was fixed by using the latest version of WW 0.6.

[patmurris]

I thought you where already using 0.6... Yes switching from flat to round was a problem before.

[zaknixon]

Well, I thought I was too, but I dropped a fresh version of 0.6 in my build path and it worked instantly.
