very cool dimitrie, i saw a blog with some nice examples of qhull connected to maya. I just played with it for a couple of minutes, but it seems that it only creates one surface per boundary, it doesen't create an actual solid for every individual cell, right? I'm guessing it's due to this current implementation and not qhull. I think most 'legitimate' uses of voronoi would require or prefer actual cell solids to be created. This way you can check inside which cell is a given object, in what position it is relative to the cell, etc.
