Visual appearence of surfaces: concepts and metrolog
Thèmes abordés

Light-Matter interactions on surfaces
• Absorption, diffusion in mediums, reflection/transmission at rough or plane interfaces
• Appearance of a spectrum and color properties (luminance, tint, colorfulness…)
• Visual appearance of surfaces (colorimetric aspect, diffused aspect, brightness, gonio-chromatic aspect, BRDF)
Characterization of surfaces (BRDF), visual aspect
• BRDF representations, models and their applications (Empirical model for image synthesis (Phong, Blinn-Phong), Physical model for simulation (He, Cook-Torrance)
• Characterizing BRDF and converting datas to models (characterisation tools, tools precision limits, optimization methods (fitting) and precision)
