Radiance and spectral radiance are radiometric measures that describe the amount of light that passes through or is emitted from a particular area, and falls within a given solid angle in a specified direction. They are used to characterize both emission from diffuse sources and reflection from diffuse surfaces. The SI unit of radiance is watts per steradian per square metre (W sr-1 m-2).

High QualityContent by WIKIPEDIA articles! The bidirectional reflectancedistribution function is a four-dimensional function that defines howlight is reflected at an opaque surface. The function takes an incominglight direction, ¿i, and outgoing direction, ¿o, both defined withrespect to the surface normal n, and returns the ratio of reflectedradiance exiting along ¿o to the irradiance incident on the surface fromdirection ¿i. Note that each direction ¿ is itself parameterized byazimuth angle ¿ and zenith angle ¿, therefore the BRDF as a whole is4-dimensional. The BRDF has units sr¿1, with steradians (sr) being aunit of solid angle.
