Boost QVM defines a set of generic functions and operator overloads for working with quaternions, vectors and matrices of static size. The library also defines vector and matrix data types, however it allows users to introduce their own types by specializing the q_traits, v_traits and m_traits templates.

Online documentation and a link to download the source code under the Boost license is available at http://www.revergestudios.com/boost-qvm/.

I took a quick look at the docs and I have to ask, "Why?" Why would I want to use your library? There is no motivation section and nothing to explain it's value. You just assume everyone knows about its purpose and value.

I don't know anything about quarternions, for example. Does QVM relate to specific fields with which I'm not acquainted thereby making the library of no use to me? How are your vectors related to std::vector? How are your matrices related to those in uBLAS? Such are the questions you should address, don't you think?

I took a quick look as well. Besides the questions above, I wondered how to access vector elements, but "Accessing vector elements and swizzling" [1] doesn't help. It's an undocumented list of incomplete declarations. [1] http://www.revergestudios.com/boost-qvm/accessing_vector_elements_and_swizzl...
