| dc.description.abstract-translated | This paper presents a method taking global illumination in ray tracing into account. A vector approach is introduced which allows to use any type of material, in particular with directional properties. This vector is decomposed into a direct component associated to light sources and an indirect one which corresponds to light having been reflected at least once. These components are estimated at a small number of points within the scene. A weighted interpolation between known values allows to reconstruct these components for the other points, with the help of gradient computation for the indirect component. Computed images are thus more accurate, at almost no additional cost, and no discretizing of the geometry of the scene is needed. | en |
