##### 2D array decrease gradient density from clippingarea border
« on: October 26, 2017, 10:45:38 AM »
Is it possible to decrease density from clippingarea border with a "gradient" in a 2D array so its superdense inside the clipping area, but on the outside it fades away random in let say 5m?

What do You mean by density?
Density is a feature of forestpack, there You can adjust density of scattering based on border.

I mean that I have a 2D array with some geometric pattern, at the edge of the border I want the amount of the objects to slowly fade off random. So let say that I have 50 objects in a row, next row could be like 37, next row 22, next 17, 12,8, 4, 1 etc. I know it couldbe done in forestpack but the way the objects is set up it would be much better to do it in RC if possible.

Oh I get it.. it can be done, when I have time I will post my solution.

Something like this:

Too bad it works not by distance to edge but in X and Y directions. If You put circle to spline, unexpected results will happen

Awesome, thanks! It´s a bit difficult to modify it so it will work with hexagons

Best would be to have all parallellograms as a separate segment but couldnt get it to work so I kept working with the hexagon. See attached file

There is a good topic about hexa-parallellograms here.
So I made 3 variants. Hope You find them useful:
