didnt work for me either with GLGraphics pre-0.9.9, works fine with the latest GLGraphics version (0.9.9) and processing 1.2.1 on osx 10.6

downloaded the latest version (GLGraphics VERSION: 0.9.9) just yesterday.
Still doesnt work under processing 1.2.1 on Windows7 64bit.

I tested the code you posted with Processing 1.2.1, GLGraphics 0.9.9 on a machine with Windows7 64 bits and I'm not able to reproduce the error. The sketch works as expected. (note about the code: it is better is you paste it in separate lines).

i am using a NVIDIA GeForce GT 330M
i will download the latest drivers. but they are actually not that old. not sure if it will change anything

its not really crashing in this case

OPENGL crashes in combination with PGraphics, but i posted this problem in another thread
https://forum.processing.org/topic/opengl-pgraphics-chrashes

in this case the library doesnt work in the latest processing version / or updates really slow when using on old processing version.

Yes i am using Aero

just in case you are interested this is the error i get when running the GLGraphics example from above in the latest processing version:

NoSuchMethodError. You may be using a library thats incompatible with this version of Processing.

i just tried your code on win7 32 with and without desktop composition (aero) enabled. in crashes the same way on both cases.

in the event viewer of windows the crash is reported this way :

henri

yes turning off aero didnt change anything here as well.

yes the aero suggestion was more like a blind guess.

same problem , if there is anything else i can test or check, let me know.

ok, I'm attempting another solution. try this one.

ok, its different now.
it starts a second borderless white screen right, but Java crashes right away (not the sketch, java SE binary itself crashes)
i install the latest version and test again.

edit: updated to the latest java version. java still crashes.
 

quick question:  did you get errors using earlier versions of glgraphics, such as 0.9.4 or 0.9.3.3?

i tested both, and they both produce the same kind of error message
"NoSuchMethodError. You may be using a library thats incompatible with this version of Processing."

Ok I see. I did yet another change in the code that might help, get the test package here.

Very intriguing. With the latest version, are you able to see the second window showing some graphics before java crashes?

No, the second window stays white, the main window stays gray. so not even one frame gets drawn.
i tried to uncomment every line beginning from the bottom.
so like you probably guessed. this was the line where it crashes.

win = new GLTextureWindow( this, 100, 100, 400, 400 );

so when drawing anything before that, it gets drawn to the screen. but nothing that i put afterwards or in draw.

Could you post the full crash log you get with the latest version of the lib? Thanks.

Do you get anything on the PDE's console?

hi,

i could not find any trace file and log file of the crash, but i could get this in the windows event viewer :

henri

@andres,
there is no log file created in the processing folder.
there is not even an processing error message in the console anymore since you did some changes.
its java crashing not the processing IDE.

as henri, i tried to take a look at the Event histody and got the same results.
some problems with the same DLL ?

ok, actually it is the nvidia opengl driver what is crashing.

i found version 197.16 on the Nvidia driver archieve. I try to downgrade to this.
The latest is 260.99 . lets see if that helps

i have 260.99 on a NVS3100M Card. crash is happening.

have you tried with 197.16 ? if not i can try it today or tomorrow.

henri

installing the 197.16 drivers doesnt work. i am looking for another old driver rigth now.

i found a great resource for old graphic drivers here : http://downloads.guru3d.com/
i downloaded and tried to install 4 different ones but sadly none of them worked or couldnt be installed.

so i went back to the nvidia website and downloaded the latest 266.35 beta driver that was released just today.
And it is working right now!
Perfect! thanks for all your help andres!

great, excellent news!

yeap ! it works !!

however the frame is null (i use it to make the window with borders.) will look at it.

henri

edit: a small sleep in the code to wait for the thread to complete the window creation solved the problem. :)

now as it works.
i have another quick question.

when drawing something to the second screen, it actually doesnt matter, if using winGraphics. as prefix.
as long as i draw it between begin and enddraw. is there a way to change that? so it works drawing to a pgraphics.
because if not i need to seperate the stuff i draw to the first and second screen, which makes it a bit more complicated in my case. just wondering.

in my code, switchin from normal opengl to the mode with preview windows and glgraphics is just a matter of:
-using right size parameter :

1.         if(Config.PREVIEW){
2.             size(Config.WIDTH, Config.HEIGHT,GLConstants.GLGRAPHICS);
3.         }else{
4.             size(Config.WIDTH, Config.HEIGHT,PApplet.OPENGL);
5.         }

and of course creating the preview window, rendering to texture and such.. other than this, all the opengl calls remain unchanged, which is great !

Hello,

It would be nice indeed to have the option to create the window resizable (or not) and borderless (or not).
For now i handled this myslef with no problem with this little utility class :

1.     class GLTextureWindow2 extends GLTextureWindow{
2.         public GLTextureWindow2(PApplet parent, int x, int y, int w, int h) {
3.             super(parent, x, y, w, h);
4.             int i=0;
5.             while(getFrame()==null && i<50){
6.                 try{
7.                     Thread.sleep(50);
8.                     i++;
9.                 }catch(Exception e){}
10.             }
11.             if(getFrame()!=null){
12.                 getFrame().setTitle("Patterns! Preview");
13.                 getFrame().removeNotify();
14.                 getFrame().setUndecorated(false);
15.                 getFrame().addNotify();
16.             }
17.         }
18.         Frame getFrame(){
19.             return this.frame;
20.         }
21.         Canvas getCanvas(){
22.             return this.canvas;
23.         }
24.     }

one thing i miss more is the missing resize functionality on the GLGraphicsOffScreen. i tried to rebuild it on the fly as the main window was resized but with no success. (got some errors about context not being the current one or similar)

henri

Adding the option to set the window as decorated/non-decorated and resizable/non-resizable was quite straightforward. I'll try to upload a new version of the lib including this enhancements in the next few days.

i tried with not much success.

how would you handle that ?

here is my try at it :

1. public draw(){
2.     if (Config.WIDTH != width || Config.HEIGHT != height) {
3.         Config.WIDTH = width;
4.         Config.HEIGHT = height;
5.         if(Config.PREVIEW){
6.        
7.             if(previewWindow!=null){
8.                 previewWindow.hide();
9.                 //previewWindow.getFrame().setVisible(false);
10.                 //previewWindow.getFrame().dispose();
11.                 //previewWindow.setTexture(null);
12.                 //previewWindow.getFrame().dispose();
13.            
14.             }
15.        
16.             //offScreenGraphics.dispose();
17.             //offScreenGraphics=null;
18.             offScreenGraphics = new GLGraphicsOffScreen(this, Config.WIDTH, Config.HEIGHT);
19.        
20.             if(previewWindow!=null){
21.                 previewWindow.setTexture(offScreenGraphics.getTexture());
22.                 previewWindow.show();
23.             }
24.         }
25.     }
26.     //end of the draw code ....
27. }

I don't know exactly how you are handling the resizing of the main Processing window, but below you have an example where the resize of the offscreen surface is controlled by the arrow keys, and runs as expected on my laptop:

hi !

thanks i got the lastest version.

about the resize: as soon as i resize the main window, the main window gets black and the texture window remains as it was and is not updated anymore. no error appear on the console.

i use this to draw the main window :

1. image(offScreenGraphics.getTexture(), 0, 0, width, height);

and i detect the resize in the draw funtion like this :

1.     public void draw() {
2.         // window resized
3.         if (Config.WIDTH != width || Config.HEIGHT != height) {
4.             Config.WIDTH = width;
5.             Config.HEIGHT = height;
6.             if(Config.PREVIEW){
7.                 if(previewWindow!=null){
8.                     previewWindow.setTexture(null);
9.                 }
10.                 offScreenGraphics.delete();
11.                 offScreenGraphics = new GLGraphicsOffScreen(this, Config.WIDTH, Config.HEIGHT);
12.                 if(previewWindow!=null){
13.                     previewWindow.setTexture(offScreenGraphics.getTexture());
14.                 }
15.             }else{
16.                 //resize now correctly handled by processing 1.0.4+
17.                 //gl.glViewport(0, 0, width, height);
18.             }
19.             System.out.println("new size : " + Config.WIDTH + "x"+ Config.HEIGHT);
20.         }
21. 
    
22.         //start openGL
23.         GL gl;
24.         if(Config.PREVIEW){
25.             offScreenGraphics.beginDraw();
26.             offScreenGraphics.beginGL();
27.             gl =offScreenGraphics.getContext().getGL();
28.         }else{
29.             pgl = (PGraphicsOpenGL) g;
30.             gl = pgl.beginGL();
31.         }
32. 
    
33. 
    
34.       //rest of the draw method       
35. 
    
36. 
    
37.         if(Config.PREVIEW){
38.             offScreenGraphics.endGL();
39.             offScreenGraphics.flush();
40.             offScreenGraphics.endDraw();
41.             //draw main screen
42.             image(offScreenGraphics.getTexture(), 0, 0, width, height);
43.         }else{
44.             pgl.endGL();
45.         }
46.     }

is there something wrong here ?

Hmmm... I think the problem is that the opengl context in the main window gets re-created when you resize it. But the texture window remains bound to the old context. I'll look at this in more detail.

i know we are switching topics here, but as it is a question about the initial code, i thought i ask here again.

its probably just a syntax question.
but how would i not only show the created winGraphics in the new window, but in my sketch window.
i am using it to show it on a projector, but would like to show a little preview in my mainsketch as well.
sure i could just draw everything again, but i thought just drawing the created winGraphics might be better.

just draw the offscreen texture using image() with the desired size:

hey thanks !

it works much better, but it's inconsistant. :(

sometimes the preview window gets white, sometime it get drawn correctly after a resize of the main window. most of the time it remains white.
also the content of the main window is garbled after resize. there are some artifacts on the window. i can send you a screen shot if you want (i tested now on a mac).

my code that handle the resize :

1. public void draw(){
2.         // window resized
3.         if (Config.WIDTH != this.width || Config.HEIGHT != this.height) {
4.             Config.WIDTH = this.width;
5.             Config.HEIGHT = this.height;
6.             if(Config.PREVIEW){
7.                 if(previewWindow!=null){
8.                     previewWindow.setTexture(null);
9.                 }
10.                 offScreenGraphics.delete();
11.                 offScreenGraphics = new GLGraphicsOffScreen(this, Config.WIDTH, Config.HEIGHT);
12.                 if(previewWindow!=null){
13.                     previewWindow.setTexture(offScreenGraphics.getTexture());
14.                     previewWindow.setSize(Config.WIDTH/4, Config.HEIGHT/4);
15.                 }
16.             }else{
17.                 //resize now correctly handled by processing 1.0.4+
18.                 //gl.glViewport(0, 0, width, height);
19.             }
20.             System.out.println("new size : " + Config.WIDTH + "x"+ Config.HEIGHT);
21.         }
22. ....
23. .....
24. }

Could you post a fully functional version of your app, including the setup code (please remove things that are not central to the resize issue)?

I did a few more improvements in the GLTextureWindow code that make sure that the texture window keeps displaying its contents even after a main context change. The GLGraphics package incorporating these changes is here.

hi,

thanks ! indeed, i don't really need the preview and to be able to resize the main window at the same time. i'll use the preview when the main window is fullscreen on the second screen (hence not resizable). that will do !

let me know if i can help somewhat for other things.
