Tīmeklisi.e. the luminance ( or radiance, i.e. the amount of light leaving a surface) of a radiating surface is independent of direction and appears equally bright at all angles. A surface obeying this law is said to be Lambertian. Paradoxically, a blackbody is Lambertian because its luminosity is the same (i.e. zero) in all viewing directions. TīmeklisIn computer graphics, Lambertian reflection is often used as a model for diffuse reflection. This technique causes all closed polygons (such as a triangle within a 3D …
