How to change a flat hexagonal grid's density with an attractor ?

Hi guys,

Has someone ever managed to change the density of a hexagonal flat grid in GH based on an attractor ?

I have tried jellyfish but couldn't keep the outcome flat.

Many thanks,

Arthur

dear daniel,

that's also very helpful for me.

thanks

Hi Daniel,

I tried to use the definition with only one point and I get the following result. Do both input point components need to be used and with equal number of points for the hexagons not to overlap ?

Thank you very much!

Thank you Daniel, this is exactly what I was looking for!

I was just wondering how to make control the strength of the attractors? I replaced hexagrid component with triangular grid component but the effect on the mesh of the attractors seems very subtle (see the image) - how can I make it more pronounced?

I've enjoyed reading all the comments here and would love to try out the adaptive hexagon grid (nervsys.ghx) in grasshopper. I'm running the latest versions of grasshopper and kangaroo but I can't get the above definition to work properly. I get four error messages, including 'input parameter chunk is missing. archive is corrupt.' I'm still new to this stuff, but if you have any ideas on how to make this work, I'd really appreciate it!

thanks!

daniel,

i downloaded your script - thanks! i'm wondering if there is a way to use the attractors to manipulate an extrusion of the hex pattern in the z-direction as well? i tried adding a u-force (with a unit z) and plugging that back into the connection for the springs and then force objects but it's still 2 dimensional. i just started using kangaroo so i'm definitely a novice. any insight would be greatly appreciated. i uploaded the grasshopper script and have been using the same rhino file you posted.

many thanks,

juliana

Hi Daniel,

I'm having trouble setting up the anchor points. How did you call out the anchor points to set up the boundary?

Thank you!

Hi Daniel,

Your nervous system is fantastic!!

Is possible to adapt this system to irregular planar surface?

Thanks,

Paolo.

Hi Daniel,

finally I found a way to adapt the grid to an irregular surface, but now the points attractors do not respond, it seems that increasing the intensity of "Maximum", the grid seems more rigid.

can you tell me what I'm doing wrong?

Thanks advance,

Paolo.

Hi Daniel!

I tried to reconnect the lines back to hexagon cells and tried to use your solution (Explode vertices connected to Kangaroo's Geometry and then PolyLine) but it doesn't seem to work, as soon as I connect Explode vertices to Kangaroo this error pops up :

"1. Solution exception:Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index "

any ideas? I'm trying to offset all the lines so I can cut out empty hexagon cells using laser.

Hello,

is it possible to get these definition with the newest kangaroo version?? I cannot open it because of three missed buttons and I need it for my university exam. Or are there other buttons which replace them??

It is my third Grashopper experience, so I´m not so good in it.

Best regards

Hey Ognek,

There are some nice examples of that but first I would need to get a hold on the script used for the applet. Actually the cutting part is quite brilliant too...

Will look into it!
