Abstract
In a method of analyzing a lighting environment, the lighting environment is initially divided into a plurality of blocks so that all surfaces defining said lighting environment may be divided into a plurality of surface patches. The surface patch that radiates the most light energy is then searched. If the quantity of light radiated from this surface patch exceeds a given value, the quantity of light radiated from this surface patch which arrives at each of said plurality of surface patches is computed. Thereafter, the surface patch that radiates the next most light energy is searched, and the quantity of light radiated from this surface patch which arrives at each surface patch is computed. In this way, the total quantity of light received by each surface patch is obtained. In this method, mirror reflection is taken into account.
