WebJun 10, 2006 · BRDF is defined as the ratio of scattered radiance (watts/ (cm 2 sr)) to surface irradiance (watts/cm 2 ); its units are inverse steradians. Radiance is used in the definition, in order to make the BRDF independent of the parameters of the measuring instrument, such as the detector aperture and distance to the detector. WebRay tracing is actually a very simple algorithm; it is based on following the path of a ray of light through a scene as it interacts with and bounces off objects in an environment. …
