I was aiming for a #micelle using something like SPH, it arguably looks a bit like that after 30 seconds... or maybe an amoeba. It's not very SPH, basically just n-body with verlet integration and this simple pairwise constraint: k*(r-48)**3 where r is the distance between the particles and k is a stiffness parameter.
u/nburn42

How do you encode that? I tired for a little while to build something to do it, but failed.
u/nburn42

I'll try again later and I'll get it eventually, but it would be nice if there was some tool somewhere.
u/tomxor
