The invention relates to a method for estimating the quantity of light scattered by a heterogeneous participating media. In order to improve the display while minimizing the required calculation time, the method comprises steps for estimating projection coefficients in a function database using values representative of density for a set of points of said media situated along at least one emission direction of light by a light source, and for estimating of the quantity of light scattered by said media, according to at least one diffusion direction of the light, using said estimated projection coefficients.
