The dual Minkowski routine is used for extracting the normal cones
10
of the mixed faces of symmetric Minkowski sum. The point is that in
11
order not to compute all faces one must do the face extraction in
12
the oppisite order of what is currently done in PolyhedralFan.
13
Equivalently, in the usual order for the dual polytope.
17
cones contains only full dimensional cones.
