  • Directional-hemispherical reflectance — is the reflectance of a surface under direct illumination (with no diffuse component). Directional hemispherical reflectance is the integral of the BRDF over all viewing directions. It is sometimes called black sky albedo . See also: Bi… …   Wikipedia

  • 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

  • Bi-hemispherical reflectance — is the reflectance of a surface under diffuse illumination (with no direct component). Bi hemispherical reflectance is the integral of the BRDF over all viewing and illumination directions of a hemisphere. It is sometimes called white sky albedo …   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
