[gl4java-usergroup] compiling

[Daniel B. <da...@gm...>]

hi,

just tried to compile gl4java (in Linux) but i've somewhat big problems. I've 
read in the archive of some successful compilations, but i can't comprehend, 
how you did that. Think, the makefile is somewhat ... ahm let us call it - 
not perfect at all. 
I am wondering why 'make x11' is trying to write all kinds of files to 
directories outside the compilation directory. If compiling fails the crap of 
compilation spreads over my file system, apart from that some rm cmds are not 
correct too. For example make tries to remove my /usr/local/lib directory ... 

rm -f /usr/local/lib /libGL4JavaJauGljJNI13tst.*
rm: cannot remove `/usr/local/lib': Is a directory
make: *** [/usr/local/lib] Error 1

That's not really kewl at all ... 
So my question is, how did the people, who stated the successfull compilation, 
accomplish that? Became root and disregard, what the script does?

The problem is probably that when you select GL_LEFT as the draw buffer, 
OpenGL draws to both the back and front left buffer. If you want to draw 
to the offscreen buffer only you have to use GL_BACK_LEFT.

[Pepijn V. E. <pep...@lu...>]

I've never used auxilary buffers so I can't comment on that. But
wouldn't it be easier to just render on the back buffer as usual, but
not perform a buffer swap?

[gl4java-usergroup] Drawing to an offscreen buffer silently

[Alban C. <aco...@mi...>]

Hi,

When I ask gl4java the count of available auxiliary buffers,=20
It returns 0.

gl.glGetIntegerv(gl.GL_AUX_BUFFERS, numbuff);

Does anyone know if auxiliary buffers are activated by default, if they
can be activated, or if I get 0 buffers because my OpenGL implementation
(nvidia, win32) would not support auxiliary buffers ?

I'm implementing color picking. It's done, it works, but my screen
flashes (a tenth of second, showing my drawn colors) because it looks
like it is drawing on a buffer used by OpenGL for display, though I'm
drawing my objects into the left buffer (because I don't have any
auxiliary buffers).

Here is the code (a bit simplified for ease of reading):

//switch to an offscreen buffer. Left buffer should be=20
//available in any implementation since it is mandatory=20
gl.glDrawBuffer(gl.GL_LEFT);
gl.glReadBuffer(gl.GL_LEFT);
//make sure the buffer can be written
gl.glColorMask(true,true,true,true);
           =20
//clean the buffer
gl.glClear(gl.GL_COLOR_BUFFER_BIT);

//draw our objects in plain red color
drawObjects();

//look for color under the mouse            =20
gl.glReadPixels(nextX,canvasSize().height-yMouseCoordinate,1,1,gl.GL_RED
,gl.GL_UNSIGNED_BYTE,pickedColor);
           =20
processPickedColorAndTellMeWhatObjectHasBeenPicked(pickedColor);
           =20
//switch back to regular display buffer=20
gl.glReadBuffer(gl.GL_BACK);
gl.glDrawBuffer(gl.GL_BACK);


Anyone has an idea of what could go wrong with those buffers ?

Thanks,

Alban Cousini=E9

[gl4java-usergroup] P4D: 3d editor and game environment

[Peter L. <pe...@gm...>]

Hello people,

P4D is a lowpolygon 3D editor and a game environment. With the editor
you can modify bonebased 3D models, animations and textures, and
import/export q3a-md3 data. The game environment (which is also used by
the editor) provides simple script-, physic-, particle- engines. the
project comes with demos of aroundbased startegy game and of a 1-st
person action game. the game data for this demos are made and editable
with the editor.

comments & and critics appreciated.
thanx for gl4java, great software.

[gl4java-usergroup] Problem with Vertex Arrays

[Danny Y. <on...@ya...>]

I've been going through the tutorials in the Red book, and everything
works great under GL4Java, but now I'm stuck on Vertex Arrays.

 

I've been trying to use glArrayElement and glDrawElements, but I can't
see anything on my GLAnimCanvas.  

 

(Oh, by the way, does anyone know where to get the source code for the
Red book.the ftp site listed in the cover doesn't work.)

 

 

Here's the code below:

 

 

import gl4java.*;

import gl4java.drawable.*;

import gl4java.utils.glut.*;

 

public class VertexArray implements GLEventListener {

 

  private GLFunc gl;

  private GLUFunc glu;

  private GLContext glj;

  private GLDrawable gldrawable;

  private GLUTFunc glut;

 

  static int[] vertices = { 25, 25,

                            100, 325,

                            175, 25,

                            175, 325,

                            250, 25,

                            325, 325

                          };

  static float[] colors = { 1.0f, 0.2f, 0.2f,

                        0.2f, 0.2f, 1.0f,

                            0.8f, 1.0f, 0.2f,

                            0.75f, 0.75f, 0.75f,

                            0.35f, 0.35f, 0.35f,

                            0.5f, 0.5f, 0.5f

                          };

 

  public VertexArray() {

  }

  public void init(GLDrawable drawable) {

    gl = drawable.getGL();

    glu = drawable.getGLU();

    glj = drawable.getGLContext();

    gldrawable = drawable;

    glut = new GLUTFuncLightImpl(gl, glu);

    glj.gljCheckGL();

 

 

  }

  public void preDisplay(GLDrawable drawable) {

   }

  public void display(GLDrawable drawable) {

    gl.glClearColor(1.0f, 0.0f, 0.0f, 0.0f);

    gl.glClear(GL_COLOR_BUFFER_BIT);

    gl.glLoadIdentity();

    gl.glColor3d(1.0,1.0,1.0);

 

    gl.glEnableClientState(GL_VERTEX_ARRAY);

    gl.glEnableClientState(GL_COLOR_ARRAY);

    gl.glVertexPointer(2, GL_INT, 0, vertices);

    gl.glColorPointer(3,GL_FLOAT,0,colors);

 

    gl.glBegin(GL_TRIANGLES);

    gl.glArrayElement(0);

    gl.glArrayElement(1);

    gl.glArrayElement(2);

    gl.glEnd();

 

 

    gl.glFlush();

 

 

  }

  public void postDisplay(GLDrawable drawable) {

   }

  public void cleanup(GLDrawable drawable) {

   }

  public void reshape(GLDrawable drawable, int x, int y) {

    gl.glViewport(0,0,x,y );

    gl.glMatrixMode(GL_PROJECTION);

            gl.glLoadIdentity();

            glu.gluOrtho2D(0.0, (double) x, 0.0, (double) y);

   }

 

  public static void main(String[] args){

            rtfm.opengl.FuGLAnimFrame frame = new
rtfm.opengl.FuGLAnimFrame(new VertexArray(), 500,500,"Opengl Test");

 

            }

Yeah, I think I might have been smoking something when I wrote that :). My
actual final solution was to put the window closing inside the same class
that I do all my drawing from (so the class that extends GLAmimCanvas).

So say you have the class Game which is the main canvas (and does all the
drawing) then you get:

   public class Game extends GLAnimCanvas implements
=09=09=09=09=09java.awt.event.WindowListener
=09{
      public void windowClosed(WindowEvent e)
                                  {

                                    System.exit(0);
                                  }
      public void windowClosing(WindowEvent e)
                                  {

                                   System.exit(0);
                                  }
=09/**And the rest of your functions*/
}

(window closing is always called first so it should never get to closed).

anyway so you create your frame add the canvas to it and then add the
event listener like:

frame.addWindowListener(Game.getInstance());

where the reference is the currently active canvas frame (my program uses
the singleton pattern). You can also terminate things safely using the key
listeners and such like.

I hope this helps,

Gary

Re: [gl4java-usergroup] gljDestroy failed (free)

[<lec...@ya...>]

I tried to do what you said, but there one thing I
must  be missing, because I don't know how to insure
that the termination comes from the canvas. I tried to
do it inside a windowClosed event, but it doesn't
work...

The main problem I have is to stop the GL drawing !

Have you any source code example ?

Thanks

Re: [gl4java-usergroup] GL4Java Nvidia crash !

[Tomas K. <kar...@ag...>]

Thanks for the quick responce !

No problems with mixed drivers since all other GL apps work like a charm.
I found an old posting with the same problem. Seems to be an bug that have
been corrected in the latest CVS code.

But then I can't get darn thing to compile :)

Is there anyone that have latest CVS binaries (Linux x86) available for
download ?

Try to use script called 'nv_check.sh' (http://www.icculus.org/lgfaq) - 
maybe you have files mixed from Mesa and nvidia ones?

Hi, All of my GL4Java apps craches when I try to launch them in Linux.
I've had this problem before with the combination RedHat , Nvidia,
GL4Java

Any solutions ?

I don't know exactly what it means but I do know where it occurs.
Basically, as I'm sure you know, since the event that terminates the main
window can be called at any time, then the GLAnimCanvas can be within a
draw() at the time the termination is called, this causes this error to
appear. The way I got around it was to insure the termination occured
correctly from within the draw. For example if you have a window close
event this can set a boolean flag within the canvas which if found to be
true terminates the application (so effectively your canvas is responcable
for terminating the application). You could also maybe set up an event
listener inside the canvas to stop the OpenGL drawing.

Hope this helps,

Gary

[gl4java-usergroup] [GL4JAVA] gljDestroy failed (free)

[<lec...@ya...>]

Already posted on the forum, but don't know if it's
still alive...


Anyway, "gljDestroy failed (free)", who knows what it
does mean ?

I have a JFrame containing a GLAnimCanvas called
"canvas", created with
GLDrawableFactory.getFactory().createGLAnimCanvas(caps,
640, 480);

Then, i add a GLEventListener
(canvas.addGLEventListener) on it, containing all the
init and display methods. But everytime I try to call
canvas.cvsDispose(), it tells me that gljDestroy
Failed. I know that it means he can't destroy the
GLContext, but i dunno how to correct it...

When I Use a simple GLAnimCanvas, without
GLEventListener, this error never occur. Is it a
GLEventListener problem ? Or am i doing something
wrong ?

Re: [gl4java-usergroup] Problem compiling GL4Java from CVS WITH JDK 1.4.1

I had this error so I try to compile GL4Java with jdk1.4.1 and now
I've got this error :

Sorry, can't find the library: GL4JavaJauGljJNI14
java.lang.UnsatisfiedLinkError: no GL4JavaJauGljJNI14 in java.library.path
native library NOT loaded complete

when I am trying to launch

java gl4java.GLContext -info


how do I set the library path ?

Actually I've set

$LD_LIBRARY_PATH = /home/pac/lib 
which contains 

libGL4JavaJauGljJNI12.so    
libGL4JavaJauGljJNI13.so     
libGL4JavaJauGljJNI14.so
libGL4JavaJauGljJNI13nf.so  
libGL4JavaJauGljJNI13tst.so  
libGL4JavaJauGljJNI.so


/etc/ld.so.conf  contains only /usr/X11R6/lib


best regards

[gl4java-usergroup] Cannot create GL Context?

[<dom...@so...>]

I've installed J2SDK1.4.0_01 and GL4Java2.8.2.0 on my machine. It worked 
well before, but recently when I uninstalled the SDK and replaced with 
J2SDK1.4.0_03, GL4Java no longer works!
I tried to run the Java port of Nehe's lesson, and I got the messages 

getGC context could NOT be created
getGC errorcould not open a GL widget -- GL CONTEXT
can't create a GL context 

What would be the problem of this? I tried installing the SDK and GL4Java 
again, but still cannot get it running. 

Thank you! 

Dominic

there is nothing about jre/lib/i386/client in the symbols.mak

I think this is in symbols.mak, which is where the change should go.

The "jre/lib/i386/client" portion of the path needs to be updated
to point to the location of IBM's libjvm.so within their JRE.

[gl4java-usergroup] Problem compiling GL4Java from CVS

[Romain P. <pa...@tu...>]

Hi all,


I thought have done evrything allright for the compilation but
actually I've got a problem when the linker starts :

gcc -o invokejvm CNativeCode/invokejvm.o \
    -L/home/pac/IBMJava2-131/jre/lib/i386/client -ljvm -ldl
/usr/bin/ld: can not find  -ljvm


how do I fix this ?
