[JAVA3D] get the coordenates

[HAroldo Pereira]

Hi

  I have a problem when I want get the coordenates of the any object (Cube).

  This cube was create with QuadArray and have rotation and translation
moving in the virtual world.

  I want get the coordenates of every six vertices of the cube. I am using
the behavior WakeupOnTransformChange. My method processStimulus have :

  public void processStimulus(Enumeration criteria) {
      //      get the geometry the cube
      Geometry geo = shape.getGeometry();

      //      Cast , because i cannot get the coordenate of the       //
  Geometry object
      GeometryArray ga = (GeometryArray) geo;
      ga.setCapability(GeometryArray.ALLOW_COORDINATE_READ);

      // get the coordenates
      ga.getCoordinate(0, db);

      // print the coordenates on screen
      System.out.println(String.valueOf(db[0]) + "," + String.valueOf(db[1])
+ "," + String.valueOf(db[2]));

      wakeupOn(wChange);
    }

  It is not works.
  Is it the best form to get the coordenates of the moving objects ?

  Anybody have any examples about its. If yes, send for me.

  I wait your e-mails

  Thanks.
