WebMay 25, 2024 · A Lambertian surface by definition reflects radiance equally into all directions. Its BRDF is simply B R D F L a m b ( 𝜃 i, ϕ i, 𝜃 r, ϕ r) = ρ π, (1) where ρ is called the reflectivity of the surface. The reflectivity varies from zero for a completely absorbing (“black”) surface, to one for a completely reflecting (“white”) surface. WebThe bidirectional reflectance (BRDF) of a surface is defined as the ratio of the luminous radiance reflected into a unit solid angle to the total incident radiance. Features and …
