A three-dimensional edge-matching puzzle is a type of edge-matching puzzle or tiling puzzle involving tiling a three-dimensional area with (typically regular) polygonal pieces whose edges are distinguished with colors or patterns, in such a way that the edges of adjacent pieces match.
An edge-matching puzzle is a type of tiling puzzle involving tiling an area with (typically regular) polygons whose edges are distinguished with colours or patterns, in such a way that the edges of adjacent tiles match. Edge-matching puzzles are known to be NP-complete, and adaptable for conversion to and from equivalent jigsaw puzzles and ...
Underside of a groin vault showing the arris. In architecture, an arris is the sharp edge formed by the intersection of two surfaces, such as the corner of a masonry unit; [1] the edge of a timber in timber framing; the junction between two planes of plaster or any intersection of divergent architectural details.
All four tilings are 2-isohedral. The chiral pairs of tiles are colored in yellow and green for one isohedral set, and two shades of blue for the other set. The pgg symmetry is reduced to p2 when the chiral pairs are considered distinct. The tiling by type 9 tiles is edge-to-edge, but the others are not. Each primitive unit contains eight tiles.
Long cuts perpendicular to the edge of the material are possible but the shallow depth of the frame rather limits how far from the edge one may cut. The much deeper frame of the fretsaw is more useful for cutting well away from the edge but conversely cannot manage the thicker materials commonly cut by the coping saws.

Edge enhancement is an image processing filter that enhances the edge contrast of an image or video in an attempt to improve its acutance (apparent sharpness).. The filter works by identifying sharp edge boundaries in the image, such as the edge between a subject and a background of a contrasting color, and increasing the image contrast in the area immediately around the edge.
