In the end, quaternions are not used just because they are faster, but because they avoid errors in corner cases.
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? regards Andy Little
