Hello everybody !

I have just installed Xith3d for my apps and tried it, my first program runs well but I got the following messages :

Exception in thread “main”

//-----------------------------------------------------------

Can anyne tell me how to fix these bugs !

Thanks advince !

I get the same thing.

??? I personally don’t know the fix,
but it is not uncommon.

I think it has to do something with the rendering thread trying to render when the application is closing. You can stop it by stopping the rendering thread first.

You might get a DI_BUFFEROVERFLOW message then (but thats only one single line).
See (this a similar problem) :
http://www.java-gaming.org/cgi-bin/JGNetForums/YaBB.cgi?board=xith3d;action=display;num=1110382938

Hope this helps!

#4

I get the same problem.
I’m running:
GNU/Linux 2.6.10 (Vector)
Java 1.5.01
AMD 1900+

The messages are printed before the program starts.
Could they still have something to do with the application stopping?

#5

Does this bug prevent you from using Xith3D at all? Or does it just print the stack trace on exit?

Obviously the former is a much more serious bug :slight_smile:

Cheers,

Will.

#6

Most of the examples were giving me this exception. I was able to stop it in the code I wrote by putting a graceful exit so System.exit(0) is not called while rendering is happening. Psuedo code is something like this in a class that extends Thread.

private boolean running;

public void run(){

while(running){
do some work…
view.renderOnce();

}
System.exit(0);
}

public boolean setRunning(boolean running){
this.running = running;
}

then call setRunning(false) on the rendering thread.

#7

This is a standard JOGL exception indicating that it was in the middle of rendering when you abruptly ended execution.

The pseudo code above is right on the money.

No, It does not stop me from using Xith3D.
Its just more of an annoyance than anything else.

I’m even getting this problem with HelloXith3D.java
Here are the last 4 lines:

    ...
    while (System.currentTimeMillis()-time<5000)
                view.renderOnce();
    System.out.println("done.");

}

Here is the order in which things happen.

Just after it press enter to run the HelloXith3D.class file, I get all that output.
Then a window opens up and the square renders.
After that the window closes.

The thing that is confusing me is that I get the ouput before the window opens and before the application ends.

Thanks for the replies
