Hello,

1)
if spheresInCell > 0, then periodic compaction is created, containing spheresInCell number of particles.
This periodic packing is then copied wherever needed and then cropped to form the desired packing.
So, spheresInCell is independent of number of particles in the resulting packing.
It is especially advantageous for large initial packing (but is usable universally), e.g. 1M particles, where randomDensePack with 1M particles would take much time. This way, you can generate a periodic cube with e.g. 1k particles and quickly copy it in the space.
With this approach, the packing generation has "almost" O(1) complexity.

**Personally** I do not use randomDensePack without spheresInCell
parameter

cheers
Jan
