Concentric Circles with Grasshopper?

[Joseph_Oster]

@Jakob_v_Schirmeister

or we do not randomize but “spiralize”?

@old_taz

You may also want to search for the term “phyllotaxis” for more info on the pattern.

Oh, is that what this thread is about? The thread title threw me off. Here are some threads you might not find otherwise:

Rotation problems

Yesterday’s version ‘Aug14e’ used Point Polar to generate the points, then interpolated them and used HFrame to orient the planes tangent to the IntCrv, similar to version ‘Aug14d’. In most cases, the results are pretty good, except for the last point where the tangent direction is not appropriate. [rotate_gid_2023_Aug14e3] This version (‘Aug15a’ below) reverts to the center point reference used earlier in versions ‘a’, ‘b’, and ‘c’ and if you look very closely, there are small differences …

And 3D (same thread):

Grasshopper pattern

I made a few changes to the code I referred you to, mostly deletions. [spiral_2024_Jul12a] 3. Attach minimal versions of all the relevant files P.S. I think it makes more sense to have small circles in the center and big circles “outside”: [spiral_2024_Jul12a2]

Voronoi Sunflower Pattern with Fibonacci Ratios

P.S. Added Voronoi component to rotate_gid_2023_Aug14e.gh (above and here) and removed everything else: [golden_spiral_2023_Jun8a] golden_spiral_2023_Jun8a.gh (6.9 KB) P.S. Added cull (white) and offset (purple) groups: [golden_spiral_2023_Jun8b] golden_spiral_2023_Jun8b.gh (31.0 KB)
