Summary:

• Diffuse surfaces reflect light in all directions.
• Brightness of a Lambert diffuse surface is the same from any viewer angle.
• Brightness of a surface varies with the angle and distance to the light source.
• Specular surfaces mirror reflect light rays.
• Law of specular reflection say “Angle of incidence equals angle of reflection.”
• Surface material models, such as Blinn and Phong, are both diffuse and specular.
