Hi Evan,
    If  you are interested in the nonrigid registration of 3D point sets,
you might
want to take a look at
     http://code.google.com/p/gmmreg/
    where you can find C++, MATLAB and Python implementations of a robust
and fast registration algorithm for both 2D and 3D point sets.  The
thin-plate splines
are used as the transformation model for the nonrigid registration.  The C++
code
is not based on ITK but it does use CMake as building tool and vnl as
numerical
library.


Thanks,
Bing
