Robert Caulk proposed the following answer:
Hello,

>What is random very loose packing?

I guess the documentation describes it best [1]:

" The resulting packing conforms in fact a gas-like state (see Cloud
denomination) with no contacts between particles. Usually used as a
first step for packing generation, before subsequent mechanical loading
that will confer a solid-like nature to the packing. "

On the other hand, a dense packing would be a packing where the spheres
are touching to create a structure i.e. the result of applying confining
pressure to that loose packing (or internalCompaction i.e. growing
sphere radii). This is what the triax example script demonstrates [2]
and what randomDensePack [3] does in the background.

Cheers,

Robert
