Thanks (and to Jason Hise)  for the information re quaternions.

FWIW boost  boost has a quaternion class

http://www.boost.org/libs/math/quaternion/quaternion.html

Even some preliminary info on rotations:

http://www.boost.org/libs/math/quaternion/HSO3.hpp

Is it possible to reuse Boost.Quaternion in a geometry library or are
there problems associated with that?
