Hi, i was wondering if it is possible to make a hook to direct3d for the purpose of substitute the meshes of the character´s faces for other face's meshes with the same structure.

The purpose of this is to add to sport games the possibility of add new faces to team's players.

I have found this tutorial,:
http://www.rohitab.com/discuss/topic/34411-run-time-directx-hooking-using-code-injection-and-vtable/
do you think that this will be possible starting from this tutorial?

i would like to know if another target of this hook could be learn about the vertex format of the game meshes and thigs like this
