This article describes our method to measure and model the reflectance of an anisotropic and colorimetricaly inhomogeneous material : the ham. The main difficulty is to find a model which is suitable to all hams. Moreover, we have to face difficulties inherent to the measurement system itself. It doesn't enable to make measurements for all the positions of lighting and observation. Phong and Torrance-Sparrow models are compared. We explain how the ham reflectance modeling can be useful to achieve tracibility control of meat products.
