i now try my pattern differently.
It quite works, i just cant figure out how i get it to work that it checks the line after the first crossing (no endpoints allowed) and if there is a second crossing, cull the line at that crossing. If there is just the one crossing, cull the line straight after that first one.
Im pretty sure that this would solve the structure. Not as a growing one, but maybe as a base for further stuff.
can anyone sort me out here? That would be awesome!
