*shrug*, I don't know of anything.

I think every vis and graphics project ends up creating their own
vector class, which is kind of silly when you think about it. Such is
life though.

FWIW, one of the projects I work on uses these classes:

It's MIT licensed so I imagine you wouldn't have trouble using it.
There's currently a known buglet w/ matrices, but we can't find a
compiler on Linux / Mac / Windows which exhibits the bug.. and I'll fix
it eventually.

Still, you probably want to search around a bit more first. Without
checking, I'd bet all of CrystalSpace, Ogre, VTK, Irrlicht, and <insert
random google result for "open source 3d engine" here> include their
own classes for vectors and matrices.
