  • Reflection of light.

  • Specular and diffused reflection

  • Smooth or gloss surface. (Mirror, glass or still body of water)Rough or matt surface. (bricks, wood, wall paint or skin)

  • Specular reflectionDiffused reflection

  • Specular reflectionDiffused reflectionAllows us to see everythingAllows us to see ourselves

  • How do we represent this is diagrams.

  • First of all, we do NOT consider the whole building or object all at once.

  • Its just far too complex.

  • We represent one light ray by drawing a single straight line towards the object. Then represent what happens to that one ray at a single point on the object

  • Tinted WindowSpecular Reflection

  • Single light ray.

  • One point of interaction with object.

  • The resulting rays begin at the same point.

  • Specular and Diffused Reflection

  • Now it is your turn to draw some diffused and specular reflected rays
