Specular reflection and phong model

WebPhong is a very basic, but real looking light model for surfaces that has three parts: ambient, diffuse, and specular lighting. Ambient Lighting: Ambient lighting is the simplest of the three parts to understand and calculate. Ambient lighting is light that floods the scene and lights up the object evenly in all directions.
