The invention relates to a method for estimating the quantity of light scattered by a homogeneous participating medium (10), the light being sent out by a environment lighting (3). In order to improve the rendering while minimizing the necessary computing times, the method comprises the steps for the:
- estimation of a first set of coefficients of projection and of a second set of coefficients of projection in the same orthonormal basis of spherical functions, said first assembly being representative of the function of incident luminance received by said medium (10) and said second set being representative of the phase function of said medium (10);
- estimation of the quantity of light scattered by said medium (10), along at least one direction of scattering of the light, from said first and second sets of coefficients of projection. |
