Hi Marco, sure that would be fine to create a thread for basics on 3D printing, please feel free to do so.

Hello Michael.
@You "; ...please feel free to do so..."
Thanks a lot.
ASAP I'm going to create this new thread.
Ciao!
From: Roni
I'm looking for a plugin that can create an actual 3 dimensional voronoi structure, not just a 2D voronoi pattern that is used with Flow or Extrude (revolve, sweep, loft etc.) The one I'm talking about as on the image.

Flow function is not sufficient ?
Your image is a particular honeycomb structure!
From: Roni
I think it's a voronoi structure and the points are spread in a space not only on a plane.

Hi Roni,
re:

I'm not aware of any MoI plug-in to do that, maybe you can find some other tool that would generate it as a polygon model file.
Seems like maybe Matlab, Rhino/Grasshopper (
https://rhino.github.io/components/triangulation/voronoi3D.html) or
http://math.lbl.gov/voro++/ might be good places to look.

Thank Michael, I'm going to have a look at it , I just rarely like to leave MOI3d , everything is very convenient there.

Seems you can make some 3D voronoi with only 2D ones ;)
i don't remember How I made that: a moment of inspiration! :D

Hi Roni,
I did with my friend Jotero lot's of 3D Voronoi Volume Mesh stuff in the past.
I am not aware of any tools for MoI that allows you 3D Voronoi points sampling
to obtain surfaces from them.
However, I attach a small tutorial (in German language) so that you can see
how one can do it with freely availabe Polygon Mesh Tools.
Please Note: the mentioned GTKRemesher, for obtaining excellent triangular
meshes is no longer available, you need to search the web to obtain a similar tools.
Best regards
Stefan

Another option would be to try to get the tool "GEEX",
which was once available from a French researcher in
this field. GEEX must be compiled and runs only under
Windows.

Does the Jotero forum always existing ?
From: Frenchy Pilou (PILOU)
Just find this free tool online :)
Result is in PLY so use MeshLab for convert it !:

From: Rudl
as I remember also Blender can make 3D Voronoi.
From: amur (STEFAN)
@Pilou, the forum no longer exists.
@Rudl, yes, you can do also Voronoi stuff with Blender, however to obtain excellent results,
like a Centroidal Voronoi Tessellation (CVT), you need tools like GEEX etc. to sample the points set properly.
Blender can't do this and the results looks therefore not good.
P.S. See for example my Voronoi Eggs, I did once in MoI, at my Behance gallery, which use also CVT.

Meshmixer is able to do 3d voronoi shapes.

Inside free Wings3D also ;)
Special "Manifold" version! (there also many cool functions in these extension !

Hi Max,
I hope that you are well!
Because I do not find the 'ping Max' thread, even after searching, anymore,
I would like to ask you, in case you have time and like to do so, if it would
be possible to allow users also to create a Delaunay triangulation, besides
a Voronoi Diagram, with your superb script?
Best regards
Stefan
From: Frenchy Pilou (PILOU)
you have this one ?
https://moiscript.weebly.com/objects2.html#delaunay
Here random points but i suppose you can input of course your own points ! ;)
From: Frenchy Pilou (PILOU)
It's me or the Voronoi plugin has not "Line, Polygon Curve" Working ? Only "Line" is enablelable!
EDIT i have an old one! :)
