Re: jogl versus gl4java. addition



Dear Dmitry,

what do you mean with: using lists the performance improved dramatically?
I switched also to jogl some times ago but I use my animator and I didn't check about fps performance. So I am curious.
Can you post a simple example about these "lists"?


	Thanks,
			Luca

after using lists jogl performance
improved   dramatically and now even better than in gl4java (a little)

what is interesting that using lists didn't change fps in gl4java

I'm doing calculations for "atom" positions from different thread

in gl4java there is a possibility to set desirable fps so I set the parameter to 100 and got ~30 so it's 15 time better than jogl is there similar functionality (setting fps) in jogl?

something definitely I'm doing wrong :-(
in jogl setup I'm doing the following:

public class GLDrawer extends Panel implements GLEventListener
....
public GLDrawer(){
GLCanvas canvas = GLDrawableFactory.getFactory().createGLCanvas(new GLCapabilities());
canvas.addGLEventListener(this);
setLayout(new BorderLayout());
add(canvas,BorderLayout.CENTER);
animator = new Animator(canvas);
glut = new GLUT();


		canvas.addKeyListener(new KeyAdapter(){
		................
		});
		canvas.addMouseListener(new MouseAdapter(){
		................
		});
		canvas.addMouseMotionListener(new MouseMotionAdapter(){
        		......
		});
        		animator.start();
	}
....
}



or maybe I have to play with GLCapabilities?

I'm using jogl's Animator class to animate


thanks

Hi,
finally I started seriously to think about moving to jogl

so I started from porting some simple example from gl4java to jogl:

1000 "atoms" set in the cube 10x10x10
are doing small random motion around fixed point

and surprisingly my gl4java running the same code (except initialization part)
5 times faster (400x400 pixel frame gl4java ~10 fps jogl ~2fps)


I'm not using swing

what I'm missing?

thanks
