After obtaining GeometryArray by
1  
GeometryArray ga = (GeometryArray)obj3d.getGeometry();


I would like to obtain a coordinate of this GeometryArray by

1  
2  
Point3f coord = new Point3f();
ga.getCoordinate(0, coord);



However, whenever I traced into the java3d newest source code, namely
1  
GeometryArray.class

I failed to obtain the vertexFormat at this line
1  
int format = ((GeometryArrayRetained)this.retained).vertexFormat;


And then, an exception was thrown out by the following two lines
1  
2  
    if ((format & BY_REFERENCE) != 0)
      throw new IllegalStateException(J3dI18N.getString("GeometryArray82"));


It looks like I can never obtain the object coordinates directly by
1  
getCoordinate()


Can anybody please help?

Cheers
JIA Pei
