the averaging is not always done...it is named 'smoothing group' in 3DS 
MAX. if your object is not smoothed, the normal of the vertices are the 
same as the face's one.

0 is : the first vertex of the face is the vertex number 0 in the vertex 
array
1 is: the second vertex of the face is the vertex number 1 in the vertex 
array
