The screen turns blank when I resize the window

Hello ,
I have a problem in my Java3D program, whenever I try to resize the window, it turns blank and the figure disappears. I followed the instructions in this link:  https://gouessej.wordpress.com/2012/08/01/java-3d-est-de-retour-java-3d-is-back/ and even tried the first example here: http://java3d.org/samples.html  but the problem is still there.

Please indicate precisely your operating system, your GPU, your driver number, etc...

Processor Intel® Core™ i5-2450M CPU @ 2.50GHz
RAM 4,00 Go
Operating System: Windows 8, 64 Bits
Hard Disk 449 GB

It turns grey.
I have just read you reply on that post and followed what you said but nothing has changed.

Please run this program and post the result here:

You may have to add jogamp.org to the exception list to run it:

This is what I got as result:

Thanks. Please can you indicate which workarounds you tried?

I tried to refresh the canvas so I added this code:
 
 RefreshCanvas3D canvas3D =
        new RefreshCanvas3D(config);
   
    class RefreshCanvas3D extends Canvas3D {
                public RefreshCanvas3D(GraphicsConfiguration config) {
          super(config);
        }
                public void paint(Graphics g) {
          super.paint(g);
          Toolkit.getDefaultToolkit().sync();
        }
      }

Ok but philjord suggested two other workarounds. Please give them a try so that we know what works and what doesn't work. Then, I will write a bug report and investigate if possible.

yes , I tried that too (I forgot to mention it)

I added : System.setProperty("sun.awt.noerasebackground", "true");  in the first line of my main.
and this:  c.getView().setMinimumFrameCycleTime(50);  after creating the canvas and adding it to a universe

I tried to add a non passive behaviour too (like Phil said)
           
 
       private static class GoBehavior extends Behavior
       {
               private WakeupCondition FPSCriterion = new WakeupOnElapsedFrames(0, false);

               public GoBehavior()
               {
                       setSchedulingBounds(new BoundingSphere(new Point3d(0.0, 0.0, 0.0), Double.POSITIVE_INFINITY));
                       setEnable(true);
               }

               public void initialize()
               {
                       wakeupOn(FPSCriterion);
               }

               @SuppressWarnings("rawtypes")
               public void processStimulus(Enumeration criteria)
               {

                       wakeupOn(FPSCriterion);
               }
       }

GoBehavior go = new GoBehavior();

then added it to my nodeRoot:    nodeRoot.addChild(go);

Rii933,

It looks like you're doing the right tests, I know it's painful but can you put a System.out.println("hello"); in your processStimulous method and ensure the console gets filled with that message. Just to ensure the main render loop is running furiously.

And also belt and braces I assume you are running 1.6.0pre12?

Thanks,
Phil

I did that now and yes the console got filled with the word "hello" .
Yes I am using  1.6.0-pre12 version

OK,
so you've given us a SSCCE in the form of the Pyramid example, and you've tried the code I suggested (Java3DSimpleTest).

I presume, given that you mentioned the sync work around that's on the net, you also tried
 Canvas3D canvas3D = new Canvas3D(SimpleUniverse.getPreferredConfiguration()){
            public void paint(Graphics g) {
                try {
                    Thread.sleep(100);
                } catch (Exception e){}
                super.paint(g);
//                Toolkit.getDefaultToolkit().sync();
        };  

?? If not please do :) .

Can you confirm that the grey is coming from the Canvas3D component parent by putting canvas3D.setBackground(new Color(1,0,1)); in and see the grey become a pink. If it doesn't then the problem is probably not with Canvas3D redrawing and we can attack other avenues of investigation.

Thanks,
Phil.

Hello,
Yeah I tried the paint method but it didn't solve the problem.
I just did what you suggested and added canvas3D.setBackground(new Color(1,0,1)); but the color didn't turn into pink , it turned into BLACK.
Thank you.

ha ha, no of course not, I should have said 1.0f,0.0f,1.0f the Color class is a crazy ambiguous thing, 1,0,1 are three ints that are almost 0 (versus 255 range max).

So something is painting the Canvas3D grey using the background color.

And if you don't resize it you see a nice Jogl window of 3D  "stuff", so you know the actual GLSurface is working initially?

oh yes , when I changed them to float numbers, it turned pink.
yeah, if I don't resize the window the shape appears normally.
