In fact, since you are well into the subject, perhaps you could tell me if there are anywhere in boost a vector dot product and cross product implemented?
I know that Emil's library of which I hope it is reviewed soon does have it:

If accepted, we plan to merge vector operations / let them interoperate between geometries.
For Janek's sake, you just define a simple traits type for any vector type, and the generic vector operations in (Boost) LA kick-in automatically.
Last but not least - I am doing frequently a 3D rotation of 3D points using quaternions for that (this could work with rotation matrices too). I suppose that I would need to implement this myself to "link" boost::quaternion with boost::geometry::point3d.
I've also implemented generic quaternion operations in (Boost) LA that kick-in for user-defined types, but I haven't yet published that code because I haven't got a chance to update the documentation.
