Abstract

This paper focuses in the interpretation of material properties of reflectivity and specularity assessed by the visual system under illumination consisting of both a focal and a diffuse component (the ‘sun-and-sky’ illumination assumption). This assumption provides for four kinds of luminance gradients: gradients of incident illumination, gradients of reflectivity, gradients of secondary self-illumination and gradients of shadowing. The analysis considers the dissociation of the material properties carried by specularity from the geometric properties of object shape, taking the sinusoidal surface as a canonical shape exemplar.
