circle packing constraints

I'm using a circle packing vb script, but i need it to do a few more things. Right now it populates a box with circles starting from the largest moving outward. This is good, however I would like to be able to setup a min and max size of the circles. The only other thing I want to do is set the start point so I could move a point such as an attractor around to get multiple variation using the same size and number. The script is included in the grasshopper file below.

Any help would be greatly appreciated,

Recursion? You can have nested clusters. But looping and recursion is something that needs to be solved separately from clusters.

No, the silhouette from multiple rectangles was for the border around the GHA icons on the banner. Though I suspect it's quite a useful little algorithm to have for making all sorts of filleted UI elements.

Hello,

I just noticed the same thing. Changing the following line (114) from:

C.GetClosestPoint(point, ct)

C.ClosestPoint(point, ct)

did it for me.

Hi David,

I am trying to follow on of these scripts. Im very very new to grasshopper and im just not sure how to go about doing what i need to do I would like to do something very similar to what is seen on this video using 3 circles with fixed radius. They should create touching tangents and not overlap as seen in this video

So you think you could help me to know how they created that in grasshopper. I would be extremely grateful. :)

Kindest

Pamela

The code above looks strangely familiar to me. Thank you, David for porting this to the new SDK.
