Hi I wonder how I can make text in 2D in may 3D game so that I can put in stuff like fps so that I can see it at all time...thx!

Hi, I have 1280x1024 most of the time, but when I run my game I want to
change it to 800x600 and I wonder how you can do that in java/jogl.

thx

Is there anybody who knows this or can it be done?

or do you haveto rotate the vertex yourself to be able to get the new positions of your vetexes after a rotation?

Hello, I have a problem when it comes to collision detection and other stuff. The problem is that I don't know where my vertexes of my objects is...

example:
I place an object with center in origo with vertexes around origo....then I use opengl glRotated and rotates my object...now how do I know the new positions of my vertexes in my object? without shaders?

thx.

I set these lightvalues...and then o draw a sphere...I wonder why my shere is blue and not red?

private float[] lightDiffuse = {0.7f, 0.7f, 0.7f, 1f};
private float[] lightAmbient = {1f, 1f, 1f, 1f};
private float[] lightPosition = {50f, 50f, 50f, 1f};

gl.glLightfv(GL.GL_LIGHT0, GL.GL_DIFFUSE, lightDiffuse, 0);
gl.glLightfv(GL.GL_LIGHT0, GL.GL_AMBIENT, lightAmbient, 0);
gl.glLightfv(GL.GL_LIGHT0, GL.GL_POSITION, lightPosition, 0);
gl.glEnable(GL.GL_LIGHT0);
gl.glEnable(GL.GL_LIGHTING);

private float[] matDiffCol = { 1f, 1f, 1f, 1f };
private float[] matAmbCol = {1f, 0f, 0f, 1f};   <---- blue? why not red?

gl.glMaterialfv(GL.GL_FRONT, GL.GL_AMBIENT, matAmbCol, 1);
gl.glMaterialfv(GL.GL_FRONT, GL.GL_DIFFUSE, matDiffCol, 1);

is there anything wrong with this code?

thx

yes, but if I don't difine a normal it is the same way!

I now have a plane that is red, and I have lights on it. One sid is red and the otherone is dark, front and back.

The thing is...it doesn't change when I change from counterclockwise to clockwise, the front is still red....

shouldn't clockwise vertex placment make the back face the viewer?

Hello, I have a problem with back and front of my polygons. When I set the GL_FRONT on my polygon with color red and I rotate, both sides are red.

and when I set GL_BACK none of the sides is red.

I need this to be able to check how to face the polygons right...or I know how to do it but I cant see any difference at this point becouse of the problem with front and back.

It should be just to set glNormal3f  to a direction and that will be fron, right?

plz help=) thx!

Method "glUseProgramObjectARB" not available

I get this message when running the lesson for shaders...does that mean that jogl doesn't support it?

Or is there a way to get it?

Is ther any support for vertex and pixel shaders in jogl and if how do I work with them there?

thx

it does not!

gears is working...but it flickers.....my app isn't flickering on my friends computer...

I have made a small testapplication where I use my mouse and when it moves triangles will appear....the thing is...it fickers on my screen,

caps.setDoubleBuffer(true) isn't working, any ideas on why?

thx

I use windows XP and my graphics card is not very good I thing, it's built into my mother board and is a "Intel(R) 82915G Express Chipset Family"

do you think it can't handle antialiasing?

Also one more thing, this is something I thing is a problem as well. I have made a small testapplication vera I use my mouse and then it moves triangles will appear....the thing is...it fickers on my screen,

caps.setDoubleBuffer(true) isn't working, any ideas on that?=)...thx

I'm running the FSAA test that comes with JOGL and I get this message, and the FSAA isn't working.

"antialiasing will be disabled because none of the available pixel formats had it to offer"

what does that mean?

do I need to change something to get it to work?

thx

How do I "grab" the cursor with JInput?

any examples?

Hello, I wonder how you get control of the mouse in a game...

not in the regular sens like listeners...but like in a shootem up game where the aim always is in the middle of the screen and it never gets to the end of the frame so you can go around hoe much you want.

For me when I navigate at the moment I can only rotate untill the cursor comes to the end of the frame.

how do I solve this?

thx!

thx Ken Russell .... stupido me=)

public void init(GLAutoDrawable drawable)
    {
      GL gl = drawable.getGL();

      gl.glClearColor(0, 0, 0, 0);
            gl.glEnable(GL.GL_DEPTH_TEST);


      gl.glMatrixMode(GL.GL_MODELVIEW);
      gl.glLoadIdentity();
      gl.glMatrixMode(GL.GL_PROJECTION);
      gl.glLoadIdentity();
      gl.glOrtho(-1, 1, -1, 1, -1, 1);
    }

    public void display(GLAutoDrawable drawable)
    {
      GL gl = drawable.getGL();
      GLU glu = new GLU();
      GLUT glut = new GLUT();
     
      gl.glClear(GL.GL_COLOR_BUFFER_BIT | GL.GL_DEPTH_BUFFER_BIT);

      glu.gluLookAt(0,0,0, 1,1,1, 0,1,0);

      gl.glColor4d(1,0,0,1);
      glut.glutWireSphere(1, 100, 100);

    }

I have made a very simple jogl thingy with just a wire spehere and when I resize or make the canvas redraw in some way the spehere rotates...

Anybody who knows why?

thx

I have tried the multisample deom in jogl and it doesn work, why is there no difference?

shouldn't this code be enough?

    GLCapabilities caps = new GLCapabilities();
    caps.setSampleBuffers(true);
    caps.setNumSamples(4);
    canvas = new GLCanvas(caps);

of course  I have done that alread...but it still gives me false!

hello everybody...new to this and I wonder what the big differences between JOGL and real openGL?

is there a large differnece?

Hello, I'm running the multisample demo and there is no differences between the two and the

caps.getSampleBuffers() method returns false .....what does this mean...doesn't my graphics card support it or is something else wrong?

thx

so there isn't realy any difference between the two, just that JSR is newer?

also, is there support for nurbs in any of them?

thx

Hello, I'm new to JOGL and I wonder what is the difference between the net.java.game.jogl and so on and com.sun.opengl and whatever the otherone is....

Which one should I use?
