The present disclosure relates generally to evaluating the surfaces of a building. The present disclosure relates more particularly to a method of characterizing a surface texture of a building surface. The method includes illuminating a first area of the building surface from a single direction and capturing an image of the first area using a camera while the first area is illuminated. The first image includes a first group of digital pixel values. The method further includes calculating a first set of values that characterize a first surface texture of the first area based on a first group of digital pixel values of the image, and comparing the first set of values to a second set of values that characterize a second surface texture, so as to produce a comparator value.

A system for rendering a building material comprising a database including an adjustable parameter relating to a characteristic of a contemplated building material, wherein the system is adapted to provide a rendered image of the contemplated building material, wherein the system is adapted to be used in conjunction with manufacturing of the building material, and wherein the rendered image has a &#x394;E, as measured according to a Color Test with respect to the building material, of less than 10, less than 8, less than 6, less than 5, less than 4, less than 3, less than 2, or even less than 1.

A radome may include a core and an outer dielectric constant (ODC) adaptation component overlying an outer surface of the core. The radome may have an effective dielectric constant variation profile from an outer surface of the ODC adaptation component, through the ODC adaptation component to an outer surface of the core. The effective dielectric constant variation profile of the ODC adaptation component may be a continuous monotonic function DC, where DCis the dielectric constant of the ODC adaptation component at the value ot, where ot is a ratio OT/OT, OTis a location within the ODC variation component measured from the outer surface of the ODC variation component, and OTis the total thickness of the ODC adaptation.

A solar control composite has improved seasonal selectivity, allowing a greater amount of heat to be transmitted through the composite during the winter and a lower amount of heat transmitted through the composite during the summer.

A method of visualizing a building material is disclosed and includes visualizing of a building material on a color calibrated photograph of a building and providing a rendered image of the building material on the color calibrated photograph of the building. The rendered image has a color accuracy, &#x394;E, as measured according to a Color Test, of less than 10. Further, the rendered image has a shadow accuracy as measured according to a Shadowing Test, of at least 75%. The Shadowing Test compares a shadow fidelity of the rendered image to the color calibrated photograph at least partially based on luminance angle and intensity and one or more rendered shadows are measured for accuracy of size and luminance.

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, Pis 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&#x2212;1) in degrees, then the two cumulative conditions exist: Y(q)&#x3e;3%+f(q) %*P*(n&#x2212;1) and Y(q)&#x3e;10%, with f(q)=24&#x2212;(3*q) and q=2 or 3.
