Abstract: A transparent sheet includes a texture in relief on a first of its main faces, such that, if n is the refractive index of the material including the texture, Pm is the mean slope in degrees of the textured face and Y(q) is the percentage of the textured surface with a slope greater than q/(n−1) in degrees, then the two cumulative conditions exist: Y(q)>3%+f(q)%.Pm.(n−1) and Y(q)>10%, with f(q)=24−(3.q) and q=2 or 3.

Abstract: A method for assessing the physically based simulation quality of a glazed objects, in particular glazing buildings or glazing vehicles. A hyperspectral canopy hemispherical image of a real sky at given daylight conditions and an image of glazed object, both synchronously acquired, are processed into a physically based rendering to evaluate the colour difference between glazing parts of a rendered representative glazed object and the glazed object of the provided image. An outstanding advantage is a realistic rendering of a glazed object by an accurate rendering of reflecting effects coming from the sky onto glazed parts whatever the viewing angles.
