Filling a volume evenly with particles without intersection

#1

hi CGTALK friends
I’ve been trying to find a way to fill a heart-shape volume with spherical particles with different sizes. As you know particles will always intersect in such a case.
What I did was using reactor and fill the volume with ready sphere objects, delete their animation keys and then turn them into particles with a birth script so that they could be sent to next events. but this is not a convenient method as the director keeps changing the position of the spheres.
I’m looking for a better solution for this problem. All your suggestions are welcomed.
thanks

PositionObjects > Separation. This sets a minimum distance in units between particles when placed on/in the object.

yes, I know this technique
but there are a few problems:
first it’s not really accurate; second, the spheres are in different sizes, if I assume the lowest radius for the separation distance, the bigger spheres will defiantly intersect with other spheres.

Pflow toolbox 2 do the trick. or thinking particles

Yes, Box #2 has a Position operator specifically designed to fill a volume with particles in a lattice.

Cool! I’ll take a look at Box2
but how is it possible with Thinking Particles?

#7

i think, im not sure, that thinking particles have colission between particles.
