  2. Texture, etc. mapping
  3. Final proposal on Friday

(Un)natural Phenomena at Surfaces

Fresnel Reflection (See also.)

How does reflection actually work?

The key concept is the index of refraction

Reflected and refracted rays

Discuss two approaches to modelling.

Brewster's Angle

Subsurface Scattering

Think about the Lambertian surface

A general formulation

Bidirectional Reflectance Function

BRDF as an example of partitioned rendering

Examples:
