hi,

had this equation to program but do not know what some of the parameters meant.

cdot(e) = (1+V.N)/2

This formula is a=for an edge(e)

What does this line mean?

the orientation of its surface normal (~N) with respect to the view direction (~V)

In programming, how do I get the V and the N for each edge of an object.

Thanks for the help.

Fyi, I do noe have in-depth knowledge on vectors/ 3D stuff.
