title: How to use python vtk to get the stereo effect?
body: <p>I got the vtk working for rendering 3D objects. Now I want to render it in stereo way. But cannot figure out how to do it I tried something like this </p>
  
  <pre><code>ren.ResetCamera()
  window = vtk.vtkRenderWindow()
  #window.GetStereoCapableWindow()
  
  #window.StereoCapableWindowOn()
  
  window.AddRenderer(ren)
  window.SetStereoRender(1)
  </code></pre>
  
  <p>But it doesn't work. Any body can give some idea? </p>
