Abstract : The invention relates to a method for representing a material by approximating a modelling origin function of the interaction between the light emitted by a light source and the material, wherein said function is defined by a texture representing pixels, viewpoints and light directions, said method comprising: for each viewpoint, steps for the polynomial approximation of the origin modelling function and for the geometrical approximation of a remainder resulting from the difference between the origin modelling function and the polynomial approximation of said function; and astep of simplifying the results obtained after the two approximations by decomposition into wavelet packets.
