I think one of the issues here is it's not very clear to someone without 
a good amount of ML knowledge how these things relate. I hear "box' and 
'cube' and think it's just a 2D vs 3D issue, and intarray isn't even on 
the radar.

Maybe what's needed are actual vector and matrix types?

In any case, if you've got a good reason why box and cube should stay 
separate then further discussion should happen in another thread.

BTW, if you haven't seen it, take a look at http://madlib.apache.org/
