  In this paper we follow the constructions of Turaev's book [Tu] closely, but
with small modifications, to construct of a modular functor, in the sense of
Kevin Walker, from any modular tensor category. We further show that this
modular functor has duality and if the modular tensor category category is
Hermitian or unitary, then the resulting modular functor is also Hermitian or
unitary respectively.
