Hello everyone, I’m relatively new to grasshopper. i try to use a 3d voronoi on a given volume. what I try to achieve you can see on the picture. I would like to apply this to different shapes and influence the cell size with attractors. Whats the best way to achieve this? anyone done something like this before?
3rd post in this thread has a routine for making a closed Brep shape into a Voronoi:
Having trouble creating an inflated Voronoi script on an surface. I’ve seen how to do this on a flat surface but have not been able to figure out how to apply it to an ungulated one. Currently having the voronoi script correct, just need to be able to inflated each section.

thank you for the quick help. I will have a look
You don’t exclusively need Voronoi here. Voronoi is splitting the space in volume. You want to connect points so can also use Proximity 3d.
There are also lot of discussion to have a gradient of density for the points. Just use the search of Goggle or Discourse.
Thanks for your answer! how can i adjust it to just fill the volume inside ? so that it is not sticking out the volume?

You can just search the forum, this question has been asked / answered infinitely on this forum. Search feature is the little magnifying glass upper right of the page.
I am trying to create a 3D voronoi inside my ‘snake’ volume.
With the help of some of you I managed to isolate points inside my volume, but if i want to use 3D voronoi it always uses the edges of the bounding box around my volume.
Anyone has an idea for a solution?

I’ve recently started using Grasshopper and I’m trying to apply a voronoi 3d pattern on top of a mesh (as seen in this picture, albeit with much smaller holes)
Now, because of the shape of the model, I’d like to have the voronoi holes be largest at the base, smaller in the mid section and non existent at the top (such that the model retains its original geometry). This is what I mean by falloff. So far I’…
Hello, I am new in Grasshopper so I use a lot of tutorials from the web. Today I tried to create voronoi ring but got this on the screenshot.
Where are the mistakes? I know this question sounds lame.
Many thanks in advance.
And also I found this grasshopper tutorial photo and couldn’t sum-up what are the steps.

Thanks for those links! Very helpful! This is exactly what I’m looking for!
I´m trying now to achieve a denser Voronoi in the areas with more details. (like eyes and nose)
In my book, the easiest way would be to add some attractor points to modify the density.
But I don´t fully understand the definitions. Could you please help me where and how to modify it?
From what i understand i need to modify the input for this guy?! Is this the right assumption?
