A method of modeling and interactively visualizing the appearance of a surface. A directed radiance model of an irradiated surface is provided, where energy is distributed as a function of spectral wavelength. The surface is divided in a plurality of part-surfaces (XI, YI), and spectrally resolved directed radiance values of each part-surface in an interval of enforced inclinations (ZI) of a simulated or real sample holder are determined for providing spectral and angular resolution. Sets of directed radiance values among the determined spectrally resolved directed radiance values, that simulate certain viewing angles of the irradiated surface are selected and visually presented as images of the irradiated surface by a graphic computer interface. The images in the graphic computer interface are dynamically and interactively manipulated to thereby simulate manipulation of the irradiated physical surface.
