QVM: Quaternions, Vectors, Matrices

set_identity(quat)

#include <boost/qvm/quat_operations.hpp>

namespace boost
{
    namespace qvm
    {
        //Only enabled if: is_quat<A>::value
        template <class A>
        void set_identity( A & a );
    }
}

Effects:

As if

assign(
    a,
    identity_quat<typename quat_traits<A>::scalar_type>());
