"WebAug 16, 2024 · Above is Blinn-Phong, fixed. This is with the same shininess as before; because Blinn-Phong doesn't have a Fresnel term, the cos(θ) fix causes the intensity to fall off dramatically at grazing angles. But the discontinuity is gone, at least. This is fixed Ward, with the same shininess as the 2nd image before. " - Phong blinn ward
