WebNov 29, 2024 · Reflectance models are mathematical functions that describe the interactions between light and surfaces. Usually, they are functions of lighting, viewing, and surface normal directions. There are various reflectance models at different levels of precision and complexity. Most reflectance models include components describing … WebMar 6, 2024 · Phong reflection is an empirical model of local illumination. It describes the way a surface reflects light as a combination of the diffuse reflection of rough surfaces with the specular reflection of shiny surfaces.

Phong specular reflection takes into account both the angle between your eye and the direction the light would be reflected. As your eye approaches the direction of reflection, the apparent brightness increases. It assumes that light will be scattered toward the mirror reflection direction. A
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
