Damn, what a hell of a coincidence. I too was struggling to get processing and opengl working with eclipse (on osx). I was comitting the mistake of using size(x,x,OPENGL) which wasn't really working. Your way of creating the renderer works, but I don't seem to have jogl on my path. I'll fix that and report back.

I don't believe many people are using eclipse with this new build, but there are updates to be made to the old toxi integration tutorial. And I know the way we're creating the opengl canvas has to be unclean.

Any thoughts from someone else?

I'm working JBuilder on Windows XP and can't get PGraphicsGL running either. Using marumushi's code I get the same error message from Processing, but in addition I get the following:

Code:

java.lang.UnsatisfiedLinkError: CreateDummyWindow
	at net.java.games.jogl.impl.windows.WGL.CreateDummyWindow(Native Method)
	at net.java.games.jogl.impl.windows. WindowsGLContextFactory$NativeWindowThread.run(WindowsGLContextFactory.java:318) 

I uncommented the debug message lines in PGraphicsGL.java, and it looks like it's successfully initalizing (it spits out all the messages, including "done creating gl" at the end).

I also tried Ben's method of using PApplet.main() to invoke the applet as an application, which bizarrely works when invoked in present mode but not when that parameter is removed. I would very much prefer to run it windowed, so I for one would like to figure this one out.

It looks like it is theoretically possible to cut PGraphicsGL loose from PApplet if one writes a new constructor that doesn't require a PApplet parent reference. That way you would have to take care of initializing the GLCanvas yourself, but would have more freedom to not use the PApplet application structure.

Of course the reason I'm so keen on this is that I have a project deadline this weekend, and have grown quite convinced of the advantages of OpenGL with the P5 library API instead of the usual brutal glVertex3() calls...

It's possible to do offscreen rendering with opengl, but this needs a special initialization when creating the opengl rendering context (tell opengl if we are going to draw on a window or on a block of pixels). I guess this must be in the depths of PGraphicsGL

another good thing to add to marumushi's code, immediately after the size() call, is:

Code:

width = g.width;
height = g.height;
 

cause for some reason this hack doesn't properly set PApplet.width/.height, they remain at zero.

Hey maybites,

I'm also running OS X, but I've no idea how to install JOGL. It seems that anywhere that I put the JAR files I get the "no jogle installed" message when I try to compile in Eclipse. So yes, I'm at step 0 here. Any help would be appreciated. Oh yeah, I should add that I'm a OS X neophyte, for I surely be able to do this in Windows... surely... yeah...

I put aside processing  for a while and learned Jogl on Eclipse and came back to processing 98.
When I tried following procedure it seems works fine.
I am using Windows XP professional.

I put < jogl.dll> and <jogl_cg.dll>
in the directory  Java\jre1.5.0_06\bin

and  I put
<jogl.jar>, <core.jar>, and <opengl.jar>
in the directory Java\jre1.5.0_06\lib\ext.

Now in eclipse,
following code works without any error message.

//**********

import processing.core.*;

public class OpenGLPApplet extends PApplet {
private static final long serialVersionUID = 1L;
float x, y;
public void setup() {
 int dim = 400;
  size(dim,dim, OPENGL);
//  size(dim,dim, P3D);
 println("Rendering with: "+ g.getClass().toString());
 x = y = 0;
}
public void draw() {
 background(255);
 directionalLight(125, 125, 125, 0, 0, -1);
 ambientLight(50, 50, 50);
 translate(width / 2, height / 2, 100);
 x += ((mouseX / 100.00) - x) * .05;
 y += ((mouseY / 100.00) - y) * .05;
 rotateY(x);
 rotateZ(y);
 noStroke();
 box(100, 50, 150);
}
}
//********************

In console window
you see

Rendering with: class processing.opengl.PGraphicsGL

if you use
size(dim,dim, P3D);
you get

Rendering with: class processing.core.PGraphics3

When I remove either <jogl.jar>  or <opengl.jar>
I can get error message saying  jogl missing or opengl missing.
This means even if I omit "import" statement,  as far as  <jogl.jar>  and <opengl.jar> are installed in the ..\lib\ext directroy,  the processing statement
  size(dim,dim, OPENGL);
obviously creates instance g of processing.opengl.PGraphicsGL!

..and for the .dlls: They just need to be in some directory that is mentioned in the Windows PATH variable, which you can modify at [ Start -> System Properties -> System -> Advanced -> Environment Variables ] (freely translated).
