Spiral distortion

First good morning everyone!
I’m a beginner in GH and esou with a big problem.
I need to distort a Hex grid to have the same effect as the attached image, and I have no idea how to do it.
Can someone please help me with this?

Hello Uggerister,

I would recommend you the site generativelandscapes.wordpress.com . Besides other great tutorials, there is a tutorial about “magnetic” fields in Grasshopper.
So the first step would be to generate a field to distort the control points ( vertices , if it is a mesh), after that you can generate your new geometry with the new points.

I hope I could help you,

Thank you Bumaye!
I’ll check immediately!

hi uggerister,

check this definiton:


Check this as well. it could be a start for you. Iterating Maelstrom several times(inside a cluster) will let you get the desired result you want.

Fantastic too, were several valuable examples. Thank you again.
Is Maelstrom a plugin? I did not find it on GH

You can find theMaelstrom in Rhino 6 GH1.0 in the Transform tab–>Morph–>Maelstrom

How can I avoid this rotation of the whole grid

HS_Kim rotates the geometry in the cluster.
So after the maelstrom, you can rotate the geometry back (with the same angle and center) back to the position.


Guys, very grateful for everyone’s help. That was the result!
