just to complete the idea. in particle simulations more often that not
we use periodic boundary conditions.
the trick is that the particles are free to move in 3D (this helps to
simulate difussion in liquids), but
the interactions (distances) are computed as if all the particles are
still in the original box.

so, the keys are euclidean distances and torus topology.

Thank you for the references.
