Phong reflection
WebThe Phong reflection model as shown in Figure 11 considers the ambient reflection component along with diffuse and specular reflections as the main components to describe the surface reflection ... WebIn the Phong reflection model, the intensity of the specular highlight is calculated as: Where R is the mirror reflection of the light vector off the surface, and V is the viewpoint vector. In the Blinn–Phong shading model, the intensity of a specular highlight is calculated as:
