WebOct 30, 2014 · What you are trying to achieve is called the Phong Reflection Model which generates specular highlights by computing the reflection vector between the normal … Phong shading may also refer to the specific combination of Phong interpolation and the Phong reflection model, which 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. It is based on Bui Tuong Phong's informal observation that shiny surf…

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 WebThe model that Phong used to simulate the appearance of shiny material is what we call in CG a reflection or shading model.

Illumination I: The Phong Illumination Model

WebThey modeled specular reflection in terms of the vector H, halfway between the light and eye. If the surface was a perfect mirror and if the surface normal, N, aligned with H then the light and eye were in the right position for perfect mirror reflection. If the surface was rougher, then the specular amount was a function of what percentage was ... WebWhile Phong shading is a per-pixel shading with normal interpolation, the Phong reflection model or the alternative Blinn–Phong shading model, though called differently, can be used at vertices and interpolated with Gouraud shading .
