do you have a definition about voronoi cells ?

2d's already there, 3d's here http://dimitrie.wordpress.com/2009/05/01/3d-voronoi-in-grasshopper/

This is actually done by creating the 3d-voronoi cells first, then iterating through each surface, re-orienting it to the xy-plane, insetting it, rebuilding it, creating a loft surface between them, and then re-orienting it back to its original position.

Hi Dimitrie, could you point out where is the 2d voronoi cells may I embed?!

Thanks!
