Defect-hiding surface textures

An interior construction, the interior construction comprising:

• a first wall board having an edge;
• a second wall board having an edge, the second wall board being positioned next to the first wall board so that the edge of the first wall board and the edge of the second wall board from a joint therebetween;
• and
• a joint compound disposed in the joint, the joint compound forming, a depression or a bump with respect to the first wall board and the second wall board, the joint compound having a visible surface covered with a texture including surface features having a height in a range from 20 μm to 2500 μm, the joint compound including particles disposed at the visible surface that form the surface features of the visible surface, wherein the surface features provide a roughness to the visible surface such that less than 50% of the visible surface is disposed at an angle smaller than 20° from a macro surface of the visible surface, and wherein the visible surface has an average rotational derivative over a range of illumination angles in the range of −88° to −65° that is no greater than 1.2*a respective rotational derivative of a Lambertian surface under the same lighting and viewing conditions,
• wherein the rotational derivative is the percentage change in radiance from the visible surface in a viewing direction when illuminated from 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,
• wherein the average rotational derivative is the average of first, second, and third rotational derivatives of the visible surface,
• wherein each of the first, second, and third rotational derivatives correspond to an illumination direction at a first illumination angle in the range of −88° to −65° from a surface normal of the visible surface,
• wherein the first rotational derivative corresponds to a viewing direction at a first viewing angle in the range of 63-67° from the surface normal of the visible surface,
• wherein the second rotational derivative corresponds to a viewing direction at a second viewing angle in the range of 68-72° from the surface normal of the visible surface,
• wherein the third rotational derivative corresponds to a viewing direction at a third viewing angle in the range of 73-78° from the surface normal of the visible surface,
• wherein the second viewing angle is at least 5° larger than the first viewing angle, and wherein the third viewing angle is at least 5° larger than the second viewing angle.
