(specular-diffused obj)
Opaque materials :
-Specular reflection: light from each
incoming ray reflects in a single direction
A tinned circuit board trace or a mirror
exhibits specular reflection.
-In diffuse reflection, light from each
incoming ray is scattered over a range of
outgoing angles. A piece of copier paper is
a diffuse reflector.

Specular Reflections :
Specular reflections are bright, but unreliable. They are bright because the
intensity of the reflection is comparable to the intensity of the light source.
Unless these angles are well controlled, it is best to avoid depending on specular
reflections.
The best method for lighting specular parts is with diffuse lighting
Diffuse Reflections :
Diffuse reflections are dim but stable.
The intensity of the reflection is reduced from that of the source depend on the
surfaces.
