Phong reflection
WebJul 26, 2024 · The Phong reflection model is an empirical (so based on observations) local illumination model. Let's see how we is it composed. In real world light is modeled by its spectrum, and each surface by its reflectance spectrum. In computer graphics often an approximation based on RGB triplets is used: Light color is a RGB triplet WebAug 24, 2024 · The angle of reflection is equal to ΘR the angle of incidence of light ΘL. Both angles are measured with respect to the normal to the mirror. The reflected ray and the incident ray are on the opposite sides of the normal. Now we are ready for our demonstration 😎. From the law of refraction reported above we know that:
