I see where you are aiming. I definitely want to be around when it
starts working.

Yes, cube is definitely a misnomer -- it suggests things are
equihedral, which they aren't. I am still looking for a short name or
an acronym that would indicate it is a box with an arbitrary number of
dimensions. With your application, you will surely benefit from a
smaller and faster code geared specifically for 3D.

The procedure is there, it is called cube_inter, but there is no
operator for it.

No problem at all -- I will be honored if you use it. Was I careless
enough not to include a license? It's not exactly a GPL -- it's
completely unrestricted. I should have said that somewhere.
Good luck,
