Delta mush isn't a smooth di per se', it's a binding state trick.
You smooth a mesh and save the delta of points from full detail to smooth
in the bind pose, you then deform and smooth out the full mesh, and lastly
re-apply the deltas back on the deformed smooth mesh to reinstate the high
frequency detail and irregularities.
A basic implementation like that is quite simple actually, and that's why
it's kinda brilliant.
