Abstract: 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.

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.

Abstract: 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(ot), where DC(ot) is the dielectric constant of the ODC adaptation component at the value ot, where ot is a ratio OTL/OTT, OTL is a location within the ODC variation component measured from the outer surface of the ODC variation component, and OTT is the total thickness of the ODC adaptation.

Abstract: 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, ?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.
