A method of rendering a graphical scene includes determining a plurality of functions that contribute to a light transport model of a scene, factoring the plurality of functions into a set of fixed functions and one varying function, determining a first radiance transfer vector that represents the product of the fixed functions in the wavelet domain, determining a second radiance transfer vector that represents the one varying function in the wavelet domain, determining an inner product of the first and second radiance transfer vectors to approximate a radiance of a point x in the scene, and rendering the scene.
