[JAVA3D] rotate canvas3D (part 3)

[SUBSCRIBE JAVA3D-INTEREST Anonymous]

Hi,

Sorry to ask again the same question, but I didn't found the solution yet : I'd like 
to rotate the canvas3D at 90 degrees, so I tryed two things :

- rotating the branchgroup for the objects and the camera : it doesn't work, I don't 
know why and I think it is not the good way

- use postSwap and postRender methods, it does not work too, so I hope that someone 
can explain me why :

Here is the code :
------------------

class MyCanvas3D
    extends Canvas3D
    {
     J3DGraphics2D g2Plan = null;

     public MyCanvas3D(GraphicsConfiguration graphicsConfiguration)
            {
  super(graphicsConfiguration, false);
     }

     public void postRender()
     {
         super.postRender();

  Rectangle2D shape =
       new Rectangle2D.Double((getWidth() - 70.0)/2.0,         (getHeight() - 
70.0)/2.0, 70.0, 70.0);
         if (g2Plan == null)
  {
      g2Plan = getGraphics2D();
  }
         g2Plan.draw(shape);
         g2Plan.setComposite(AlphaComposite.Src);
        g2Plan.flush(true);
    }

    /*
    public void postRender()
    {
        super.postRender();

        if (g2Plan == null)
        {
            g2Plan = this.getGraphics2D();
     g2Plan.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                             RenderingHints.VALUE_ANTIALIAS_ON);
        }

        g2Plan.rotate(Math.PI/4, 600D, 600D);

        g2Plan.setComposite(AlphaComposite.Src);
        g2Plan.flush(true);
    }
    */
}


The rectangle is well drawn but if I use the other postRender method, nothing happens 
!!!

Where is my mistake ?

Thanks
