Hi everyone, so I want to create a VEX code where I can scatter random circles into this grid without intersection. I am a little bit stuck while I'm doing the "While()" loop. Basically, what I need is that if the circles are intersecting, I need it to change the scattered seed. Does anybody know how to fix it? Thanks in advance!

cncverkstadActually, I'm trying to do it like this. http://paulbourke.net/fractals/randomtile/ [paulbourke.net] . By the way, that's quite an interesting result you got there. Is it okay if you send the hip file as well?
something like this Or?

Konstantin MagnusThank you for the link. It is quite similar to what my goal is, which is like this, http://paulbourke.net/fractals/randomtile/ [paulbourke.net] . The only problem that I'm seeing is that it uses a solver for it. I'm wondering if it can be done without a solver.
This tutorial might help:

Take a look at @tamte's example file: https://www.sidefx.com/forum/topic/18255/#post-85827 [www.sidefx.com]

ajz3dThanks for the link. It is quite similar to what I'm aiming for, however, I do notice that there is not much size difference between the circles, and there are still some empty spaces that need to be filled.

Here is a modification of your file. The algorithm should be similar to the algorithm in the link you have given.
In fact it is repeating, to find a random location on a grid, where there is "enough" space to find a circle with a specific radius. The problem is, that the remaining space can get very small, that it is almost impossible to find a valid position for the next circle, because the probability is getting smaller with each circle and there is no guarantee that it finds such a position. So in this case it might be better to omit this circle and try another (smaller) one.

AizatulinWow, thank you so much for your help. This is much harder than I think it was supposed to be. Yeah, I guess that it is better and faster to omit the circle than keep finding a random position until we found the valid one.
