Yes. Basically, you are bringing things into the tangent space around
one of the points. The projection onto this subspace would be the
closest of -+x.
(guessing from iphone ?? ;) )
i would add this function.
what do you mean by bring them closest ?
that I should prefer x+y over x-y if:
dist(x,y) < dist(x,-y) ?

You just have to find the choice of sign that brings them closest.
Adding a function would be good.
did anyone figure out how to find the mean orientation from a set
of rotations ? It is not a simple mean operator on quaternions as
q and -q represent the same orientation.
