I'm wandering if any of you have used it...there is a Rhino plugin, also comes as a standalone application or integrated into CATIA through the HexaMeshTools product etc.

Hi neo, it looks interesting, but also note that it seems to be focused on mesh generation for use in finite element analysis type applications (like for structural analysis and that type of thing), not really for rendering and polygonal modeling.

3Dcoat seems to allow to create meshes like this too. Here a link to the discussion about this kind of meshing at the Rhino forum:
