title: How to use vtk (python) to visualize a 3D CT scan?
body: <p>I wanna visualize a 3D CT just like the following image.

  (Note that I only need the part at bottom right)</p>
  <p>I am using python and vtk. Could anyone provide an example on it?</p>
  <p>Suppose the variable &quot;array&quot; is the CT data whose shape is (512,512,3), then what should I do with it?</p>
