WebIn other words, normal and light direction are parallel vectors, although of opposite direction ( [1, 0, 0] for normal and [-1, 0, 0] for light direction). To calculate the total diffuse factor, we have to take dot product of normal and light direction. Let's have a look at what we get in this case: dot_product = Nx*Lx + Ny*Ly + Nz*Lz.
