| Popis: | This paper deals with light sources in computer graphics. Different kinds of light sources and different types of solutions generally used are first described. Then, a new solution for directionally dependent light sources based on No\'e and P\'eroche's model\cite{Noe00-HRBLS*} is proposed to avoid drawbacks of bilinear interpolation. The use of singular integrals with locally supported functions allows a fast and accurate reconstruction of goniometric diagrams. Application to point light sources is finally compared with some experimental results. |
