JOGL Hello World

Here is a basic JOGL application:

import java.awt.Frame;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

import javax.media.opengl.GL2;
import javax.media.opengl.GLAutoDrawable;
import javax.media.opengl.GLEventListener;
import javax.media.opengl.awt.GLCanvas;

import com.sun.opengl.util.Animator;

public class JOGLAPP implements GLEventListener {
public static void main(String[] args) {
new JOGLAPP();
}

Frame fr;
GLCanvas canvas;

public JOGLAPP() {
fr = new Frame("JOGLAPP");
canvas = new GLCanvas();
canvas.addGLEventListener(this);
fr.add(canvas);

Animator anim = new Animator(canvas);

fr.setSize(300,300);
fr.setVisible(true);
anim.start();

fr.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
super.windowClosing(e);
System.exit(0);
}
});
}

@Override
public void init(GLAutoDrawable drawable) {
GL2 gl = drawable.getGL().getGL2();

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

// init opengl here
}

@Override
public void display(GLAutoDrawable drawable) {
GL2 gl = drawable.getGL().getGL2();

gl.glClear(GL2.GL_COLOR_BUFFER_BIT | GL2.GL_DEPTH_BUFFER_BIT);

// draw things here

gl.glFinish();
}

@Override
public void dispose(GLAutoDrawable drawable) {

}

@Override
public void reshape(GLAutoDrawable drawable, int x, int y, int width,
int height) {

}

}
