To be honest, I'm not sure what all the items on your list mean; in
particular the word "robust".  However, if you mean that you want to
do exact geometric computation, then I would recommend the polyhedral
data structure of CGAL (www.cgal.org).  

CGAL should be able to "support" much of what you need, although you
might have to write some small bits of code.
