Circle packing based on image sampling

Hi all, love what's going on in this video with image based circle packing:

Does anybody have a clue on how it's done or where to find the definition?

Best, Easymatic

One way uses lloyd's algorithm. Daniel Piker posted an example a while back: http://www.grasshopper3d.com/group/hoopsnake/forum/topics/lloyds-al...

I use a Daniel Piker script

from this discussion

http://www.grasshopper3d.com/group/kangaroo/forum/topics/circle-pac...

and I add some random sort depending on the Colour Brighness, because the number of point depend on the surface of the circle sorting is done according to the square of the radius (R1/R2)^2.

You have to enter the number of point needed to fill the space, multiplier could be used to adjust well the filling.

Hi Laurent,

Do you think it would be easy to use ellipses in stead of circles like in the video?

Best! Frank T

I'll post the definition later today after cleaning it up a little...

Beautiful! thanks Daniel! Will it include ellipses?

Here's the definition.

It requires the latest version of Kangaroo. The first time you open it, you will need to set the referenced assembly locations in the scripted component to your own copy of KangarooSolver.dll

For different images you'll probably need to adjust the range of circle sizes and number of circles to get a nice packing.

This is only for circles - ellipses would be possible, but quite a few changes would need to be made.

Hi Daniel,

Would you mind explaining how to use this definition? Is it missing something? (there is no connection after image). Also, I have tried with different images, but it doesn't change the position of the points nor the circle sizes.

Please let me know how it works :)

Thanks!
