[Closed] scatter without collision

One solution would be to simulate a physic simulation (physX or whatever), and collapse the result.

I think using particle can do it too

+1 for pflow.

if your prepared to live with a certain amount of inaccuracy then pflow will do a decent enough job otherwise a physics solution.
