No. Minkowski is an operation that CAN be used to make a cube round.
Minkovsky does a UNION between ALL resulting objects when you
translate one object along a vector with the endpoint inside the
second object. This looks "asymmetric" but it isn't: the result is the
same whichever way around you do it.
So for the rounded box, you might think that you're shifting the box
around along all points inside the sphere, but the same rounded box is
what you get when you move the sphere around all the vectors that fall
inside the cube.

The plan was simple, like my brother-in-law Phil. But unlike
Phil, this plan just might work.
