The Phong reflection model (also called Phong illumination or Phong lighting) is an empirical model of the local illumination of points on a surface designed by the computer graphics researcher Bui Tuong Phong. In 3D computer graphics, it is sometimes referred to as "Phong shading", particularly if the model is used with the interpolation method of the same name and in the context of pixel shaders or other places where a lighting calculation can be referred to as “shading”. WebMay 12, 2024 · The original Phong formulation had its share of problems (not reciprocal, not energy-conserving), but thankfully, other people took care of that. The modified Phong BRDF looks like this, where $\vec \omega_{r}$ is the perfectly reflected light direction and $\alpha$ is the Phong exponent controlling the roughness:
