You can use TesselationWrapper. Check documentation and feel free to ask 
more when something is not clear.
Note that getVolPoroDef() is supposed to return a python array but it 
was never tested yet. On my side, I'm using  the function Volume(id) to 
get the volume of a Voronoi cell.

Cheers.

/*! \class TesselationWrapper
 * \brief Handle the triangulation of spheres in a scene, build 
tesselation on request, and give access to computed quantities : 
currently volume and porosity of each Voronoï sphere.
 * More accessors in course of implementation. Feel free to suggest new 
ones.
 *
 * Usage :
 * TW.setState(0)
 * O.run(1000); O.wait()
 * TW.setState(1)
 * array = TW.getVolPoroDef(True) //syntax here?
