As the angle between … WebJan 1, 2016 · The complete Phong reflectance model represents reflected light as a linear combination of ambient, diffuse, and specular components. The ambient component is a small constant accounting for weak scattered light in the scene. The diffuse component is represented by the Lambert's model. Hence, the reflected radiance is computed as.
