Morph to 3d-object-form

hello,
i learn to create some structures in 3d. at the moment the 3d-voronoi is reated within a cube.

is it possible to morph it into a 3d-form ?

at the moment i get this:

edit:

i thought, if i reduced the 3d-population to an intersection of cube & sphere, i could create a corresponding 3d-voronoi.

I’m not quite sure what you’re up to, BTW, why don’t you use Solid Intersection something like this?
