title: Volume of Voronoi cell (python)
body: <p>I'm using Scipy 0.13.0 in Python 2.7 to calculate a set of Voronoi cells in 3d.  I need to get the volume of each cell for (de)weighting output of a proprietary simulation.  Is there any simple way of doing this - surely it's a common problem or a common use of Voronoi cells but I can't find anything.  The following code runs, and dumps everything that the <a href="http://docs.scipy.org/doc/scipy-dev/reference/generated/scipy.spatial.Voronoi.html" rel="noreferrer">scipy.spatial.Voronoi manual</a> knows about.</p>
  
  <pre><code>from scipy.spatial import Voronoi
  x=[0,1,0,1,0,1,0,1,0,1]
  y=[0,0,1,1,2,2,3,3.5,4,4.5]
  z=[0,0,0,0,0,1,1,1,1,1]
  points=zip(x,y,z)
  print points
  vor=Voronoi(points)
  print vor.regions
  print vor.vertices
  print vor.ridge_points
  print vor.ridge_vertices
  print vor.points
  print vor.point_region
  </code></pre>
