How can I make this pattern?

Hi guys, I accacidently saw this pattern today and I tried to make it with voronoi but failed. So does anyone know how to make it?

Need some help to create chisel wood textures in grasshopper

I am kind new in Grasshopper and mostly I try to use it as as a tool to create and analyse woodcarving designs and shapes/ forms. I would love if some have some tips or a tutorial how we could recreate a chisel gauge wood texture as in the photos bellow. Idea is to test in grasshopper ideas before I finally carving them with hand tools or use 3d prints for copper molds. I was thinking that maybe a good idea would be to use attractor points to control the size direction and symmetry. Thank yo…

Mesh carving/chiseling (How To)

Here are some renders of simple meshes that were carved/chiseled with 2 methods. Explanations will follow.

What would be the best way to patch this?

I have created several polylines based on a voronoi pattern. Each segment has a slight concavity to it to yield a scalloped form. However, I’m not sure what the best manner would be to build a surface between all of these polylines. Bonus points if you can also recommend a way to add a fillet to each arched edge so soften the form. I appreciate any input! [23_capture_01] 2018.08.23_mcneel_forum.gh (11.8 KB)

The thing is, what I did with voronoi really doesn’t look like the picture. So maybe it was made with another solution?

Looks like your cells just need more size variation.

Hi guys, I made a similar one, but not exactly the same. I post it to give anyone who is interested some inspiration.

[laurent_delrieu]

Here is a way
take you curves (lines), split them in n segments with a length ratio defined
1 to 2 here

The use the line to draw an ellipsoid (length in X depending on length of segment), width and height defined by a slider.
Play with sliders

Thanks Laurent! I guess this is the right sulotion.

I guess this is the right sulotion.

There is hardly ever a single “right solution”.

[523484432 (Alex Mao)]

Haha yes yes, I should say “one of the best solutions”.

I never use Patch because it’s often not precise enough, but I played with the ‘S’ and ‘F’ input values to get results that Brep Join into a single polysurface, adapted from your code. A bit slow…

I’ve seen scalloped surfaces like this done differently but can’t remember how. Maybe Kangaroo?

[Joseph_Oster]

I took the liberty of simplifying your code while increasing the random placement of the points, as suggested by @ftzuk.

Here is one from @DanielPiker:

What would be the best way to patch this?

It’s true this approach relies on using spheres of the same size (otherwise you’d need to calculate a weighted Voronoi diagram). The size of the Voronoi cells doesn’t need to be linked to sphere radius though - that’s just a result of how his points are distributed. Talking of distribution, a suggestion for one way of getting a nicer distribution here would be to apply a few iterations of Lloyd’s algorithm (repeatedly moving the Voronoi points to their cell centroids). Making the cells more cen…
