To find out average unit normal vector at each polygon vertex
At each polygon vertex as demonstrated by point V in the figure above, the normal vector is acquired by averaging the surface normal of each polygon sharing such vertex. Hence, for any vertex V the unit vertex normal will be specified by N¯v
Here K → 1 to n are the surfaces in contact along with the vertex v.
