Sažetak
The article deals with Monte Carlo modeling of uncoated printing paper surface based on light reflectance from the surface and on subsurface scattering. The paper surface was simulated using randomly oriented microfacets characterized by a specific parameter, critical azimuthal angle ϑc. Determination of the value of ϑc was based on the idea that the standard deviation of the light reflected from a paper surface is not equal to zero, and can be recognized as noise. Noise, i.e. standard deviation of the reflectance measured on actual paper samples, was used for calculating ϑc and, consequently, for obtaining theoretical surface models. The results show a satisfactory agreement with the real paper surfaces and indicate that ϑc can be one of the important parameters in future simulations of this kind.
