Abstract: A system for visually enhancing a surface. For example, the system may include an assembly that may be configured to project a laser line across at least a portion of the surface. Versions of the laser line may be projected at an angle of incidence relative to a plane defined by the surface. For example, the angle of incidence may be in a range of about 5 degrees to about 60 degrees. In one version, the laser line may be substantially perpendicular to a central axis of the surface. In addition, the laser line may enable enhanced, qualitative user visualization of the surface and non-planar distortion in the surface.

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: The present disclosure relates generally to a surface structure for construction products, for example, suitable for construction products that cover visible interior surfaces, such as drywall and ceiling panels. The present disclosure relates more particularly to an interior surface construction product including a visible surface covered with a texture including surface features having a height in a range from 20 μm to 2500 μm. The visible surface has an average rotational derivative that is no greater than 1.2*a respective rotational derivative of a Lambertian surface under the same lighting and viewing conditions. The rotational derivative is the percentage change in radiance from the visible surface in a viewing direction when illuminated in an illumination direction as the surface rotates about an axis that is perpendicular to a plane defined by the viewing direction and the illumination direction.

Abstract: The present disclosure relates generally to building surface products, for example, panels suitable for forming a building surface. The present disclosure relates more particularly to a building surface product including a gypsum panel with an upper edge that overlaps a lower edge of a neighboring gypsum panel.
