Reflection Characteristics of Surfaces (cont.)

• Specular reflection

  • Typical of bright, shiny surfaces

  • Reflected color depends on material
    • in plastics is color of point source

    • in other materials may vary between color of light source and color of material

  • Dependent on light source position and viewer position
    
    

  • For perfect reflector, see light only if a = 0

  • For real reflector, reflected light falls off as a increases
