WebBlinn-Phong specular reflection A common alternative for specular reflection is the Blinn-Phong model (sometimes called the modified Phong model.) We compute the vector halfway between L and V as: Analogous to Phong specular reflection, we can compute the specular contribution in terms of (N·H raised to a power n s: where, again, (x) + max(0, x).
