After a quick look at it, it seems nice ( however i wonder about it's
performance considering it treats vectors as 4x1 matrices, and all
vectors and matrices are defined for any given number of dimensions --
something that UBLAS does already ). What I would want to see however
is an optimized library defining 3/4d vectors/matrices and common 3d
computational geometry tasks optimized for speed. And additional thing
that I'd like it to be is to   allow as readable code as possible and
to have it integrated with other boost mechanisms.
