Deformation wear map

I just found I way in Houdini to generate a kind of "wear map"..this method record the area of the geometry that most and less was deformated and worn along the animation.
I dont know but perhaps be usefull for create procedural textures, to get diagnostic from capture bones (find errors)..can be usefull too for create wrinkles dynamicly and etc..
SideFx could join it as attribute generated automaticly by Capture Sops ;D
