Generate Tessellation on sphere surface only

[woongy94]

Dear Romain

Thank you for providing such an amazing tool

I already made my -T script like below

neper -T -n from_morpho -morpho "diameq:lognormal(2,0.05),1-sphericity:lognormal(0.05,0.03)" -domain "sphere(10,1000)" -dim 3 -format "stl"

and it works perfectly :)

Now I want to generate a Tessellation only on the surface of the domain (in my work, it is sphere), and to connect the intersections of Tessellation with the center of the sphere by a line. Can you tell me is it possible or not?

Kind regards,
Jinwoong Choi

Your configuration is what you get when all the seeds are located on the sphere. You can give it a try by defining such seeds and loading their coordinates using -morphooptiini "coo:file(...)".
The coordinates will have to be "randomized" a bit (not all exactly on the sphere).

Can I ask what your application is? Why are you building a 2D tessellation on the sphere?

Thank you for your kind reply! :)

I'm applying it to make a battery cathode particle model.
I also success to make another kind of geometry which will applying to my another work.
But now I want to make this kind of structure using with Neper.
(Kind of centroidal voronoi tessellation? volumetric voronoi tessellation?...)

So I was trying to make a 2D tessellation on the sphere..! :)

Oh, I got the solution from #149 ..

My approach was wrong I think..
and when I change my mind on my approach, I can find another solution to make my model.

Now I will going to understand and apply the 'centroid' in the Neper

I really appreciate you to supply Neper this is amazing tool :)

Thank you
