A unit of luminance (or brightness) equal to 1/pi candle per square centimeter Physically, the lambert is the luminance of a perfectly diffusing white surface receiving an illuminance of 1 lumen per square centimeter
Calculates surface by interpolating between normals of two adjacent polygon normals, resulting in a smoothly shaded object The surface reflectance is not incorporated, which yields lambert shader suitable for matte surfaces with unpolished, chalk-like look This shader is based on the lambert's cosine law discovered by Johan Lambert, a sixteenth-century astronomer and physicist Lambert's cosine law simply states that the intensity of light on a surface is proportional to the angle at which the light hits the surface
A unit of luminance One lumen per square centimeter leaves a surface whose luminance is 1 lambert in all directions within a hemisphere (The candela per square meter is the preferred unit of luminance )
English composer and conductor (1905-1951) a cgs unit of illumination equal to the brightness of a perfectly diffusing surface that emits or reflects one lumen per square centimeter
