I have this daoubt, allways I use lunchbox for basic patterns but in this shape the hexagons in one side looks with high lengnght.  
There is a way to adjust maybe with Graph Mapper the density of the uv on a surface to get more or less equals hexagons on surface??

Can I get a result like the first dome in the next picture?

you sure can, though bear in mind that ‘result’ you’re looking at _does not show equal hexagons_, but rather a gradient, or so it seems.

for that maybe check this discussion:

> [@Gradient pattern using non-uniform hexagons](https://discourse.mcneel.com/t/gradient-pattern-using-non-uniform-hexagons/86808/2):
>
> Maybe something like this? or these two [image] [image]

Furthermore, what you see in the domes image is also the hex pattern already distributed on a shape, with (apparently) near-the-edge polygons culled out.

Something like this:

Alternatively, if you look into the example in the [linked discussion](https://discourse.mcneel.com/t/gradient-pattern-using-non-uniform-hexagons/86808/2), perhaps you can apply the hexagons to a sphere yourself.

In the attached file, I share you a couple of multiple approaches you could have:

- also note that I have edited your slider for U and V to only use _even_ numbers

You are right, the point, I was looking for hexagons not distorted more or less concentric, you catch up the idea.  
I’ll check the file and thread. thank u so much.

I’m getting this

I cant undestand why 😕  
Edit: got it I was thinking the las item will be the hex pattern, I’ll keep going.

oh not at all 😄 sorry - I didn’t want to wait for gh to split the surface into all those pieces so I trimmed the edges off for  
the screenshot…

The hex curves aren’t planar so getting surfaces from splitting will take a minute- if you planarize them then it’s easy to use fragment patches or weaverbird’s mesh from lines

No success ! 😑 I tried map twice , another suggestion.

Are you trying to replicate the [Kreod pavilion](https://www.designboom.com/architecture/kreod-pavilion-at-greenwich-peninsula-in-london-by-chun-qing-li/)?

yes, as practice, i have a methodology but first i’m trying to have more or less same sizes of hexagons.

The critical step is drawing the initial coarse panel layout. Notice that the vertices on the end boundaries are all connected to 3 faces, except for the row one up from the base. Also there are 8 edges along the back edge, and only 4 along the front edge.  
Once you’ve modelled this and the base surface to wrap it onto, subdividing and relaxing to get more even sizes is relatively easy.

I’ve been working with surfaces so I want to jump into meshes I was thinking this would be a nice example to take practice, is a little hard for me now but here I go

The surface you are using is perfectly suitable to study meshing - you just have to ignore hexagons for a minute!

Grab that same surface and plug it into a _surface points_ component, then create a _mesh surface_ component. Then connect the Us and Vs from one to the other, to make a neat mesh based on the surface’s point count. It’ll be acceptable because your surface is untrimmed.

Then do the same without the _surface points_ and instead add your own sliders to the U and V of _mesh surface_ component. Then triangulate that mesh and explore other meshing options like mesh machine.

excuse the rant, it was in response to:

> [@HEEN](#):

you might be well past this point 😅

thanks buddy I hope share soon a decent copy of kreod Pav 😛
