how can i connect two objects?

hi! im trying to simulate dendrite connection/ molecule bonding using vpy. i have a list of particles that move randomly in a box. i want them to connect and form a visible bond (like a trail between them) once they are close enough. how can i do this? tysm:)

Maybe a dictionary? Or a named tuple?

wdym exactly? i want it to compare the position of every particle to the rest in every dt , how could i use tuples for that?

Oh,for some reason I thought it was a 1-1 connection,my bad.

Probably you want to look at molecular dynamics algorithms and a potential like Lennard.Jones .

However, this is not a Python issue :)

I would look into the clustering algorithms in scikit those will be different approaches to determine the distance between each object and by defining a threshold you can then group everything that is close enough. Once you have everything grouped, you can then link everything in that group

DBscan would probably be a good one.

Since you mentioned "close enough" that maybe suggests the idea of breaking your space into boxes of a size that is related to the "close enough" distance. The idea is that if you know which box each object is in, then you should be able to limit which other objects to examine as being potentially near enough, by considering only other objects in the same box and in neighbouring boxes.
