I have

<code>
public class NetworkDrawer implements GLEventListener
{   
    GLU glu = new GLU();
   
    public static ArrayList<Node> nodes = new ArrayList<Node>();
    public static ArrayList<Arc> arcs = new ArrayList<Arc>();
</code>

At the top of my class, then i have my init method as:

<code>
 public void init(GLAutoDrawable drawable)
    {
        GL gl = drawable.getGL();
        glu.gluOrtho2D(-40.0,40.0,-40.0,40.0);       
    }
</code>

So all i want to do where is chage the clipping volume to -40 to 40 in both the x and y direction, as i have a set of 2d coordinated i want to play as points and that seemed the natural way.

My display method:

<code>
 public void display(GLAutoDrawable drawable)
    {
        GL gl = drawable.getGL();
        gl.glClear(GL.GL_COLOR_BUFFER_BIT);
        gl.glLoadIdentity();
        gl.glColor3f(1F, 0F, 0F);
        gl.glVertex2d(0, 0);
        gl.glVertex2d(0.5, 0);
        //drawNodes(drawable);
        gl.glColor3f(1F, 1F, 0F);
        //drawArcs(drawable);
    }
</code>

Im drawing two points to test my new co-ordinate system is in place, so they should be very close, but instead they are bing drawn with the default co-ordinate system -1 to 1 in both x and y, so one point in the middle, and the other half way between the middle and the right hand side of the window.

Any idea how i get my correct -40 to 40 system in place?

How do i di that with the new version, just started JOGL today, could someone give me a simple example say if i wanted to call gluOrtho2D in the init method.

Thanks.
