Radiosity Methods

(1)Equation 


 or  ( Energy Balance )


where 	


Bi: B are the radiosity of patches i and j

	Ei: the rate at which light is emitted from patch i

	Pi: patch i's reflectivity

	Fj-i:formfactor (configuration factor ) , which specifies the fraction of energy 
	     leaving the patch j that arrives at patch i.

	Ai, Aj areas of patch i and j.
