Does it matter if the spheres are tightly packed or not?

That image you linked to required testing for intersecting spheres, which can
take quite a while depending on the number of spheres being tested. For that
image I used a program created with voro++, which sped up intersection tests by
finding the spheres' nearest neighbors (so that each sphere didn't have to be
tested against every_other_sphere).

There's another method I just stumbled upon which is even faster, but the
spheres are by no means tightly packed.

Why do you want a sphere full of spheres? What will you be rendering? For things
like filled gumball machines, the methods I mentioned aren't very useful. For
something like a gumball machine, I'd recommend using Blender's physics sim
along with a script I wrote that exports to a POV-Ray array the positions,
sizes, and rotations of all objects in a group. That way you can combine
Blender's physics with POV's perfect geometry (and using less RAM than meshes).

Tell me what you'll be doing, and I'll try to help you out.
