voronoi/voronax question

Hello everyone!

I am experimenting with voronoi and I wanted to ask if it's possible to create a surface in rhino, not grasshopper and afterwards to apply voronoi (preferably relaxed) to this surface?

For example in the attachment is a shape and an exoskeleton wrapping the surface.

Is it possible to make something like this, not random but with the logic of a building - where you need supporting structure? At least in a way where you choose the points (for voronoi) yourself?

Thanks in advance!

The images I used are from this video. I have watched it, but didn't get what function to use.

What function do you want ? Did you search a bit on this forum with tag like Morpheus Zaha Hadid City of Dreams ? There are also plenty of papers for this building, Google is your "friend" !

Look at that :

Apparently there is not relation with your title !!!

My goal is not to repeat this building. I did look it up, thank you. The goal is to make voronoi 3D surface on existing rhino model, so it wraps around the shape, kind of like with this building, but using the relaxed voronoi.

One solution to your problem could be to mesh with triangles your surface (do you have one ?) and then apply dual mesh. It will look like Voronoi/Voronax. Because at the end what you want is a mesh with faces with more than 4 edges. I did that in some of my example.

You could mesh by hand or using MeshMachine or whatever triangle mesher.

Try to come back with a definition, a model, a sketch from you, references of what you see, what you didn't understand ...

When I model a shape in grasshopper and apply voronoi it becomes very angular. But a relaxed voronoi, as I understood, could be more soft and wrap the surface (blue cellular structure). My shape has an inner vessel and a surface around it. I want to keep the curve and be able to control the points that make voronoi structure to play with density (sizes of holes).

for example in this tutorial: https://www.youtube.com/watch?v=tctEXTDFPdc ,

the voronoi is created flat, and applied to a surface after. I want to have more control over the cellular structure you get in the end.

voronax seems to be perfect as it also has a nature reference, but I couldn't find tutorials for it and I wonder if it's possible to use it on the 3D surface that is created in rhino.
