3D Voronoi

[hajamull]

I can't find out how to make a 3D voronoi or somthing similar with Wings 3D 2.01 mlab. The tools with Voronoi in their names seems to be working best on the surface of objects. The closest thing I get so far is the Monodisperse foam tool. If I use Inset and intrude on the whole object i get a kind of 3D voronoi skeleton, the edges on the outer surfaces are fine, but on the inside the edges have some sort of double geometry that gets more obvious when you try to smooth the object.
The approach i Grasshopper i somewhat different:
"Take a random cloud of points
generate the 3d voronoi
scale the edges of the cells towards their centres, and also towards the centres of the faces.
connect these 2 sets of scaled edges with mesh quads and join
cull some of the outer faces
subdivide and smooth"
Can I do something like this in Wings 3D or maybe another more "Wingsy" way. After all Grasshopper is node-based and Wings is not. I tried to attach an image that shows the effect I'm after. I don't know if it shows in the message.

Best regards
