The above image shows (from right to left) some of the attempts over the year to create a near-perfect mesh that is suitable for current-gen facial animation techniques. The top left is the end result for our 'Male Head BaseMesh'.
The wireframe can be deformed in such a way to allow for detailed facial animation, a standard feature in most modern games today, and would definitely have a substantial part to play in our final game.
During the development of this mesh, the same is in process for body parts also, and will be posted up in the near future.
