FIELD: data processing.
SUBSTANCE: invention relates to the field of data processing and allows you to simulate the actual reflectivity from a surface. This computer-implemented method for matching the reflectivity model with data with an extended dynamic range for a plurality of measured sample data points associated with the reflectivity on the surface of a material comprises the steps of: getting a plurality of points of measured sample data associated with the reflectivity on the surface of the material, transforming the obtained points of sample data, creating a non-parametric compactly tabulated one-dimensional representation for a plurality of factors in the microfacet model.
EFFECT: invention provides fast convergence, resistance to random initialization and full automation, without the need to adjust the parameters of the material.
