different Voronoi sizes by attractor points

Hello,

I guess I am kind of stucked in how to treat data...

It is very elementry level but somehow I dont know how do solve it....

What I want to do is to have bigger hole near attractor points and have similar sizes of voronoi for other parts...

I will add reference image that I want to achieve..

Thanks

Seung

Hi Igor,

Thank you for your script!

I'm very new to grasshopper, in fact never used it before but needed it for a design involving voronoi and this result is exactly what I've been looking for. I downloaded your script and input a bounding rectangle and multiple attractor points. But instead of creating varied cell sizes according to distance, it just gave me uniform voronois. Can you help me?

For fans. "Ethnic motives" on the basis of Voronoi with multiple attractors with Lunchbox tool....

Very ingenious way to generate the points you use in the Voronoi!

Hello Igor,

I'm just a starter in grasshopper. you work is very interesting. I just wonder how it can be imply on the real landscape with multiple or one hilltop? I mean by using topography curves and hilltop attractive points ... here is the landscape picture with some steepest path that i want to use them later on ...
I am a kind of stock in it. if you give me your email i will send you the file. It would be great if you or someone else help me :)

Hi,

This is great. I want to apply this kind of creating voronoi structure to 3d lofted surface. I tried switch it to my surface but it didnt work very well.

Do you have any clue about how to build it for 3d surface? It is about changing cell sizes not, offset distance.

What I have is basic voronoi on 3d srf. And many failed.

Best regards.

Hi Igor,

I have been playing with your definition for some time and try to apply this type of Voronoi to a sphere. I just can not get this right somehow. I was wondering if you applied your definition to something like a sphere and if you would be willing to share your findings.

Thank you,

Oliver

Hi Oliver,

as the sphere has specific structure (two edges degenerate in points), it is difficult to transfer to it the Voronoi. But it is possible to use FacetDome tool. To move the main thing to the sphere any curves (or to find crossing of the sphere with any figures) and to divide the received curves by points. The remained space needs to be filled with random points.

Best regards.

This is great and gets me started... Thank you so much for taking the time and adjusting your previous definition for me!!!

Thanks fernando,

More experiment with imposings/intersections. They can give surprising curves and samples.

Best regards

Hey,

I have a question to a script I puzzeled together from some other scripts, which is similar to this thread. I'm an architecture student, and my goal is to do some landscape design using grasshopper.

The functions I need in my scrirt are:

1. the voronoi which becomes bigger when further away from the attractors

2. extruded planes in the voronoi at the attractor, which become lower when further awy from the attractors

3. colours for differnet kinds of landscape

Some of it works already quiet well, but my problem is, that I cant extrude the voronoi on all the attractors. Its only extruded on one attractor. Can someone help me with that problem?
