The 0th order case is fitting spheres for two sets of points and using translation plus radius-scaling to transform; order 1 uses [something like an oblate spheroid, etc.] (https://en.wikipedia.org/wiki/Spherical_harmonics)\r\n\r\n~~This can create stuff like this (the stuff of Matti-related nightmares), for order 4 trying to fit a true surface using just dig points (orig surface is gray, dig in dark gray, spherical transformation/deformation in purple, resulting surface in green; [code in a gist] (updated 9/29)(https://gist.github.com/Eric89GXL/75f4ee8ee930f5e5bc47cff9d7f0e8e3))~~\r\n\r\n~~I still need to cross-check with other packages that the transformation is correct.
