title: Python: Calculate Voronoi Tesselation from Scipy's Delaunay Triangulation in 3D
body: <p>I have about 50,000 data points in 3D on which I have run scipy.spatial.Delaunay from the new scipy (I'm using 0.10) which gives me a very useful triangulation.</p>
  
  <p>Based on: <a href="http://en.wikipedia.org/wiki/Delaunay_triangulation">http://en.wikipedia.org/wiki/Delaunay_triangulation</a> (section "Relationship with the Voronoi diagram")</p>
  
  <p>...I was wondering if there is an easy way to get to the "dual graph" of this triangulation, which is the Voronoi Tesselation.</p>
  
  <p>Any clues? My searching around on this seems to show no pre-built in scipy functions, which I find almost strange!</p>
  
  <p>Thanks,
  Edward</p>
