pack.randomDensePack does that, except that it is far more flexible
since you can specify the shape using GTS surface (arbitrary) or a few
geometrical primitives; that is used in scripts/examples/gts-horse.py
(the horse is imported from external file and packed regularly; you
could use pack.randomDensePack instead of pack.regularHexa as well) or
in examples/concrete/uniax.py (hyperboloid).
