It reads positive on outward edges, negative in inward creases, and zero on flat ground. That one number is behind most of the wear that needs no texture: edges rubbed lighter, dirt and moss gathering in the pockets, snow sitting on top but not in the seams.
Unlike the other fields it needs the geometry itself, because whether a point is an edge depends on its neighbours rather than on where it is.

Watch out
Read it from the same geometry you are about to shade. Anything that moves vertices in between leaves it reading flat everywhere.
