Because I will only have one 10k packing and if I need to cover larger 
volume, I can place one copy next to another and then clip the results.

Yes, but I need high density with constant radius and more or less 
isotropic. Something like from TriaxialTest, but periodic. I will try 
with non-periodic for now, but I will have to generate perhaps 80k sample.

Thanks for your ideas,
