Voronoi Multipipe on Polysurface

Hi, I have looked online and can’t find any tutorials showing how to use Voronoi pattern onto an organic polysurface created in Rhino and I am overwhelmed by the new software. I have previously gotten Voronoi patterns only as a surface, however it does not generate a nice pattern as I’d expect… Looks decent from the top but the sides are messy


I would like to output something similar to the video link I have attached, unfortunately they do not show their process. I have attached my polysurface and the video link, I was wondering if there was a code that can be applied to several organic shapes using brep/geometry as I have several of the polysurface shapes I would like to transform. Many thanks and I really appreciate the help. Video Link: https://youtu.be/JzUIQVMQNwQ?si=fv8tIb3USBQB6O8R

Hi @R_umi,

Probably he used a workflow with bounding box, 3D voronoi and splitting the surface with the voronoi cells.

Hi, thank you for your reply! I have got a similarish output by projecting the Voronoi pattern onto the polysurface but I wanted to achieve something more like the image I have attached (but for my single model) where it wraps around the structure in a neat way from all sides, as you can see in parts of the model it creates those weird circle intersection which I am trying to avoid as the whole polysurface should be covered in the Voronoi pattern.

This is trimesh’s dual

Does anyone know how I can create the voronoi on this polysurface?? (made up of multiple spheres boolean unioned together)
im new to grasshopper so any tutorials/help will be greatly appreciated!!

Hi @R_umi and @Georgia_Forrest ,

This method I described above works for both projects.

thanks, I have applied this to my polysurface but am getting this…

looks okay.

thank you. Im looking to create another facade like this (below) is there a way of using the polysurface again to create the inflated surface

how do I get the outcome to become visible?



in shaded view it shows all the geomotry but in artic or rendered it isnt visible

You will have to use kangaroo.

depends on what you want. If you bake the custom preview you will see the colours in rendered mode. If you want a frame you will have to model it.

Hi Erik,

I only just had the opportunity to take a look at your solution. I really appreciate your guidance and has helped me get closer to my ambition. One confusion, after increasing the multipipe on my model I get some weird parts in certain areas, I was wondering if I could get a confirmation if this is due to the geometry I have provided you with or to do with the grasshopper file, so I can go back and re-assess my model if needed. Also I was wondering if there was a way to create the multipipe so that the intersection points create something like this rather then the rigid connections.




Last image shows increasing the populate geometry count, I was wondering if there was a way to create the pattern so its more concentrated in some areas, and less in others? I found this tutorial that sort of shows the sort of pattern I’m looking for that wraps around my surface - do you believe this is a better method?

Thank you for your help! It appears I’m missing two commands, the topoligizer and material textures. However, when the gh file starts up I’m unable to download the plug-ins as it says they are . Do you know where I can find them to get the code to work?


I only managed to find one on food4rhino, I hope it’s the correct one.
