nD skeletons as the discontinuities of the graph of the distance map in (n+1)D space. Cyclographic map of Descriptive Geometry (generates the ruled & developable surface); its discontinuities form the skeleton. Relation with the Hamilton-Jacobi equation. The shocks of this PDE correspond to the skeleton.
