Out of popular demand, I have compiled a nice file detailing the possible uses of the Voronoi node, complete with the accompanying rhino file.

Hey man! you saved me…
I was looking to something similar to this, actually vornoi in grasshopper!

so, thx a bunch!

my pleasure! if you would like to lemme see what you’re going to do with the thing, please do so i’m interested to what further use my work is put to (gives me some sort of intellectual satisfaction).

hey man… one more q..?
the script that you implemented into grasshopper is working only if boundary points are forming a shape in xy plane. Is it possible to turn it vertically if you know what I mean.
I am trying to apply modified version for the facade design. of course i could finish everything , bake and then rotate , but… right way is something else …
and letting you know about the result as soon as competition is finished

Hi Dimitrie,

Thanks a lot for sharing your knowledge. We are ussing your script for Voronoi. It’s been awesome.

But we have a little problem: we managed to defined the border and the inner points, but somehow there are 2 areas that adds up. We tried assigning the points in several different ways, but it doesnt help to solve the problem.

Is there a specific sequence to assign the points?

I uploaded the definition and the Rhino file here: https://rcpt.yousendit.com/665836195/650bd9b40e9a336c8d1e247ed7fca819

dimitrie,

i am a big fan of your work.
i have a problem perhaps you can help.
we are looking for a scripts that can read in
curves from the rhino contour function then flatten, label and space them for laser cutting. what is the best way to go about this either in grasshopper or vbs scripting.

thanks in advance

Hey Dimitrie!
This definition is so cool, exactly what I need for building a 3-D Voronoi Diagram! Since I want to project light onto the surfaces of the cells I need them to be closed tho.. I tried with a cap-param but it closed the cell only at the bottom, not on the top.. Do you have any idea how I could close the surface?

Cheers!
Julia

  hey Julia,
  
  First of all: there’s a special voronoi node under the mesh tab in the grasshopper version 0.6.0019+ or something, and i would recommend using that node since it’s faster. Otherwise, what you need is essentially a “patch” command – and this one is not available in gh or in .net sdk. there are some workarounds though: http://www.grasshopper3d.com/forum/topics/rhino-patch-in-grasshopper

Hey Dimitrie!

you just saved my facade! This definition is perfect!!
Got a slight problem though.. I entered my own poins, the voronoi itself works perfectly,Nurbs cells and straight cells both looking good, but then the offset is not working on all cells and i‘m not getting any error.. any ideas??

Thanks in advance!!

  Hey dimitrie and M . i am also developing a facade on voronoi pattern, so can you help me in this. Well i am new to grasshopper so i am taking a lot of time to generate a facade. Please urgent help needed …
  
  Many thanks …
