I want to create a gradient effect in Y-direction. From the bottom to top the circle should disperse. I used the jitter command but didn’t get the desired output! Thanks in advance! Perforated screen.gh (16.4 KB) [2021-02-06 12_53_48-Grasshopper - Perforated screen]

Is there a way that the circle disperses from the center to the sides?

Small thing: In the Sub List component the D input you need to subtract 1, otherwise you duplicate 1 point :wink:

It does. You are building a domain out of a list length. If you turn up the density to 1 you now are trying to get a sublist with indexes 0 to list length, meaning you will try to get 1 more point then there are points in the list. That will cause it to reference the first point twice, as you can se…

I know… If you increase the value to 1.0, that’s not the gradient any more. :wink:

Okay. Well it’s actually very nice with the density at 1, so I fixed it for my version. By the way: as always thanks for the super simple implementation. I was already playing around with it and adding more things, that’s when I noticed the small oversight. Small things like this have caused some sm…

Another simple fix is just set the wrap indicies input to ‘false’. [Canvas at 01;02;28]

Good idea. Still I think subtracting 1 will be more acurate. If you set density to 0.5 then you get exactly half of the grid points and not half the points plus 1 :wink:
