Circle packing based on amount of circles

[Fenno]

Hi again!

I am trying to fill a 2D curve with equal sized circles based on a variable amount of circles.
So for a small amount the radius of the circles will be bigger and the circles will be optimally aranged within the curve.
The circles must stay within the curve and cannot intersect.

What is the best way to do this?

See this discussion:

Disk covering algorithm

Yes, in that definition only the centres are kept on the target surface. If you want to keep the whole circles on the surface, one way is to inset boundaries of the target surface by the radius like this: [image] diskpack_offset.gh (20.1 KB)

Also this one which adjusts the radius automatically:

Circle packing with adaptive radius

Filling surfaces with a given number of equal sized disks without overlaps is a topic that has come up quite often here, and I’ve posted numerous examples and variations of how to do this with collisions. However, one thing I’ve always wanted to improve upon is automatically finding the correct radius. It is possible to do this by manually adjusting with a slider until they fill the shape without overlapping, but I thought it would be nice if this radius could also be found by the solver. So h…
