Bi-hemispherical reflectance

Bi-hemispherical reflectance

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".
