This is an implementation from an article on Wikipedia, which never lies. http://en.wikipedia.org/wiki/Kabsch_algorithm The rotation outputs are way too far off. It has 3 points to rotate 2 dimensions, so that seems like enough to do a good job. The 'Delta' vectors are the difference between A rotated to B, v.s. B. -- Lance Norskog [email protected]
