QVM

Emphasis on 2, 3 and 4-dimensional operations needed in graphics, video games and simulation applications.

Free function templates operate on any compatible user-defined Quaternion, Vector or Matrix type.

Enables Quaternion, Vector and Matrix types from different libraries to be safely mixed in the same expression.

Type-safe mapping between compatible lvalue types with no temporary objects; f.ex. transpose remaps the access to the elements, rather than transforming the matrix.

Requires only C++03.

Zero dependencies.
