Okay, what is isometry, as in symmetries of a shape which are invariant up to isometry. Is there a more technical definition than just something that is the same about a shape even if you rotate/scale/animate it?

Is the Green's function using the distance as a 'measure' of covariance in some sense ?
Secondly, is there a concept similar to Mutual Information (used to measure similarity/correspondence while aligning images), defined for meshes ? It may not work in all cases, but could help eliminate naive one-to-one matching !
