I'm trying to make the jump to eclipse, but openGL is giving me some strange problems. The same code acts differently in processing and eclipse.
When the sketch is running from eclipse it makes strange stops, especially when the mouse is over the sketch. Also openGL from eclipse is not fast, actually when I use PFont at the same time it seems slower.
The thing is I'm not sure openGL is running at all, maybe only P3D or something because I don't need to import openGL in my eclipse sketch, but I need to have jogl.jar in my reference libraries.

I do have -Djava.library.path="C:\programmer\processing\libraries\opengl\library"
in my VM arguments

And I don't get any regular warnings when it's running but when I'm switching back and forth from eclipse and processing testing this issue I sometimes get a bug (I haven't reported...sorry).

Here is and example with eclipse and processing code:


eclipse code:

package digitalDecay;

import processing.core.*;

@SuppressWarnings("serial")
public class TestText extends PApplet {

 final int WIDTH = 300;
 final int HEIGHT = 200;

 int rotate = 0;
 int num = 70;

 public void setup() {
   size(WIDTH, HEIGHT, OPENGL);
 }

 public void draw() {
   background(150);
   fill(255);
   translate(WIDTH / 2, HEIGHT / 2);
   rotate(radians(rotate));
   for (int i = 0; i < num; i++) {
     for (int j = 0; j < num; j++) {
       ellipse(i * WIDTH / num - WIDTH / 2,
               j * WIDTH / num - WIDTH / 2,
               5, 5);
     }
   }

   rotate++;
 }
}


processing code:

import processing.opengl.*;

final int WIDTH = 300;
final int HEIGHT = 200;

int rotate = 0;
int num = 70;

void setup() {
 size(WIDTH, HEIGHT, OPENGL);
}

void draw() {
 background(150);
 fill(255);
 translate(WIDTH / 2, HEIGHT / 2);
 rotate(radians(rotate));
 for (int i = 0; i < num; i++) {
   for (int j = 0; j < num; j++) {
     ellipse(i * WIDTH / num - WIDTH / 2,
             j * WIDTH / num - WIDTH / 2,
             5, 5);
   }
 }

 rotate++;
}

I've had problems with openGL before with smooth(), but that's a graphic card or driver problem, this is different because in processing there isn't any problems.

Does anyone have an idea what the problem is. I've been trying for days and I really don't have any idea.

Thanks for the help.

It made openGL faster and cleared the problems switching from processing to eclipse, but didn't help with the skipping issues though.

P3D doesn't skip by the way, only openGL.

hi,

i just tested your code. it runs slow both in processing and eclipse (drawing 4900 ellipses is slow, nothing you can do about that )
However, I don't see any (irregular) skipping in eclipse and processing.

another thing you could try... go to your project properties-> Java Complier -> Compiler compliance level: 1.4
But actually I'm not sure how these two settings (compiler compliance and JRE setting) affect the sketch. These are just the settings that worked best for me.

Have you tried to write a sketch that actually CAN reach the desired frameRate? Standard framerate is 60. My machine renders your example with max. 10fps. Does the skipping appear when you set the frameRate() to 10 or if you draw way less ellipses? (my machine makes 60fps up to num=25)

hmmmm updated my drivers and now it works like a charm.

Sorry to have wasted your time and thanks a lot for the help.

These error appears when you start two applets or application in eclipse or you have an applet started from processing and then start one in eclipse.
