DLA simulation

[soyuz]

I generate a Point and make it do a random walk and stop near r< rmin. Now I generate another point and do the same etc. But how can I tell a point that he meet oher?

That is easy,
you should hold the points coordinates somewhere, then you compare the coordinates.
does this help you?
