http://www.boost.org/doc/libs/1_58_0/libs/geometry/doc/html/geometry/example... It seems to me Geometry is about shapes and shape operations and iteration. QVM has nothing to do with shapes or iteration, but it defines a complete set of generic namespace-scope quaternion/matrix/vector operations, which Geometry doesn't. I also think that it shouldn't: if you want to use such operations with Geometry types just use the QVM adaptation machinery

I've always dreamt of boost.geometry supporting 3d, and qvm might be a way to accomplish that. However, it might make the most sense for boost.geometry 3d components to utilize qvm under the hood to implement 3d geometric functionality rather than make qvm part of boost.geometry. Perhaps others can imagine better ways to accomplish these goals.

This is indeed exactly what is wished. Boost.Geometry currently uses Boost.UBlas for some vector/matrix operations. But those operations are, actually already from the start, planned to once be replaced and extended, and QVM looks like a good candidate for that. Regards, Barend
