Curvature Map

A map that stores the convexity/concavity of the mesh. Also called Concave, Convexity, Pits & Peaks, Worn Edge.

The colors can be used to mask where the surface would get more wear, where it would accumulate more dirt, where sub-surface scattering might occur, to check for surface continuity, etc.
