Grasshopper

algorithmic modeling for Rhino

Hi there!

Need some help..

 

I have a grid and i want in a way to exclude some points of the grid that are affected by a "circle" around an attractor point.

 

What i have, is the grid, extracted the X and Y of all points, an attractor point and a circle around it, divided in points which also i extracted X and Y of these points...

 

so i am thinkig whether i can use booleans or something like that in order to achieve the desired result

 

i attach the .ghx file and an image...

 

maybe there is a simpler or total defferent way... if you are confused with what i write though willing to help, ask me to explain you better what i mean!!!

Hi Strageor, do you want to cull the points inside the circle?

YOU ARE AMAZING....

so simple... but in my mind was so much complicated...

and what about the oposite? keep the points outside the grid?

 

thank you so much!

i meant keep the points inside the circle...

found it...

thank you .... :D :D :D

what about more cirlces in the same grid?
then I would do this

need to take some grasshopper tutorial lessons from you...

thank you pieter!

huh... didn't even know the containment component existed. I usually use a f(x) function and represent the effecting distance with a circle as you know the functions such as x<300 with x being the distance between an attractor and a list a points is only a radial one. Containment will allow any shape to work. Nice.
