Directional-hemispherical reflectance explained

Directional-hemispherical reflectance is the reflectance of a surface under direct illumination (with no diffuse component).^[1] Directional-hemispherical reflectance is the integral of the bidirectional reflectance distribution function over all viewing directions. It is sometimes called "black-sky albedo".
