Résumé: The paper presents a combined "nite element and quasi-random walk method to solve the general rendering equation. Applying "nite element techniques, the surfaces are decomposed into planar patches that are assumed to have position independent, but not direction independent (that is non-di!use) radiance. The direction dependent radiance function is then computed by quasi-random walk. Since quasi-Monte Carlo quadrature is applied here to an integrand of "nite variation, this method can take advantage of the superior convergence of quasi-Monte Carlo integration.
