Hello,

because the link is dead, does somebody know a similar definition or where I can find it?

Thank you!

Drowsey Telfast,

Yes, in my definition I am driving the radius of each circle with the remapped distance values.  You could create a custom curve of your own, and a reference plane for that curve, and use the "orient" component to place that curve at each point on the grid.  Once oriented, you can plug the remapped distance values into a "scale NU" component for XYZ inputs.  This will scale your custom curve as you wish.  An example of this technique can be seen in my "image sampler" definition.  Good luck!

Is there a way to use your own curve ass opposed to using a circle rectangle or polygon? Can't seem to figure it out

I will let you know ,thanks !

that's simple...

you can "sort" the list of radii so they are in order from lowest to highest value, and then using "split list" you can separate them out into little groups of similar values.  From there you can use multiplication, division, and rounding to simplify them into the integers you want, or you can simply replace those numbers with a new integer of your choice.  hope that helps.

Thanks ,really clear. This application of grasshopper is often used for paneling application in the real life. I was just wondering if there are some components/full algorithms that allow you to create families. Putted in other words, in this case could be ...I need 10 circle of radius number x and 30 circles of radius number y etc.etc. I face the topic of the families in digital project, here in grasshopper I ma getting there just now. I f you know something about it would be really precious to me. Thanks twice.

Alessio,

I'll try to explain as best I can.  This definition takes a single shape, (either circle, square, or polygon) and it populates that shape onto a grid of points.  The optional shapes simply let you use squares, circles, or polygons as the shapes to be used.  Once the shapes are laid onto the grid, the script tests the distance of each shape from the attractor curve.  This distance ranges from very small to very large.  So then the list of distances is then "remapped" to a value that can be controlled.  By "remapped" i mean, that the entire list is scaled from it's current bounds (maximum and minimum values) to a target domain.  so if I have a list of numbers (0,4,6,10) with a bounds of (0 and 10) and I remap them using a target domain of (0 to 1), I will get a new list (0.1, 0.4, 0.6, 1.0) You may want that target domain to be related to the size of the original grid, to avoid overlapping shapes.  (radius should never exceed 1/2 of the grid spacing)

hope that helps,

-Sean

Thanks for sharing, really helpful and more completed of many other tutorials I've seen. Looks to me a bit unclear when I face the final part when the values are remapped. Why two lists entering, what it means optional domain list..and what actually is happening remapping all that numbers. ? I hope in a exhaustive reply.

Nice one! I´ve just started researching and I like the extra shapes in the definition. thanks for sharing
