Abstract
A method is provided for representing a material by approximating an original function modeling the interaction of the material and of light emitted by a light source, which function is defined as a function of pixels, of viewpoints, and of light directions, the method comprising: for each viewpoint, the steps of performing a polynomial approximation of the original modeling function and a geometric approximation of a residue resulting from the difference between the original modeling function and the polynomial approximation of said function; and a step of simplification by decomposing the results obtained from the two approximations into wavelet packets.
