WebJul 15, 2010 · Phong shading approximates this distribution by raising the dot product to an exponent called the shininess factor, with higher shininess giving a more polished shine and lower factors giving a more diffuse sheen. This final specular factor is then multiplied by the specular colors of the light source and surface, and the result added to the ... WebOne of the most common reflection models is the Phong model.
