The relevant formulae are in Bookstein (1991) Morphometric Tools for Landmark Data: Geometry and Biology. Cambridge University Press (and other places). The only difference for 3D is U(r) = |r| and obvious adjustments to matrix sizes, etc. The more difficult problem is generating effective visualizations in 2D of volumetric transformations.
