[vtkusers] How create an offscreen render window in VTK ?? Please Help

[Deepak Roy]

hello everybody,
   
  Do you know how to create an offscreen vtk render window in VTK ? 
   
  I want to render into the off screen render window and then get its z-buffer using GetZbufferData () and work on its z-buffer.
   
  Or is there an offscreen buffer similar to vtkRenderWindow.
   
  Please Help.
   
  Thanks in advance.
   
  Regards,
   
  Deepak
