WebJul 18, 2015 · 2. The equation is a consequence of the symmetry of the reflection of the light about the normal: We know from the law of reflection that the angle between R and N is the same as the one between L and N. Therefore it's also clear that: R•N = L•N (assume all are unit vectors) From symmetry, it's also evident that. R - (R•N)N = - (L - (L•N)N) WebJul 6, 2024 · The Phong reflection model in particular describes the light reflected from surfaces or emitted by light sources as the combination of 3 components: diffuse, … WebAug 31, 2024 · The light and the position need to be in the same space.
