Method for Visualizing Functionally Defined Surfaces with a Complex Microstructure

Functionally defined surfaces with a complex microstructure for realistic scenes are proposed. A wave optics-based model is described for visualizing surfaces with microscale roughness, which enhance the realism of objects under various observation and illumination conditions due to diffraction and mutual interference. The model simulates light transport and surface, which serve as its input data. Diffraction effects with surface roughness are demonstrated. An approximation of spatial coherence using a Gaussian filter is considered, which ultimately allows us to visualize not only glares but also higher-order diffraction.
