In high school physics I learned that specular reflection occurs on smooth surfaces where light rays are reflected at the incidence angle while diffuse reflection occurs when the surface of an object is rougher causing light to bounce at many angles.
Since one theme of lecture has been that realistic images tend to be marked by noise and irregularities, when would specular reflection be used to model any surface? Does it cause an unnatural glossiness?
Does this work for non-spherical objects as well?
Yes
