Bidirectional reflectance distribution function — The bidirectional reflectance distribution function (BRDF; {f r(omega i , omega o) }) is a 4 dimensional function that defines how light is reflected at an opaque surface. The function takes an incoming light direction, omega i , and outgoing… … Wikipedia

Albedo — The albedo of an object is the extent to which it diffusely reflects light from the sun. It is therefore a more specific form of the term reflectivity. Albedo is defined asthe ratio of diffusely reflected to incident electromagnetic radiation. It … Wikipedia
Reflectivity — In photometry and heat transfer, reflectivity is the fraction of incident radiation reflected by a surface. In full generality it must be treated as a directional property that is a function of the reflected direction, the incident direction, and … Wikipedia
