Among those that do, a regular tessellation has both identical regular tiles and identical regular corners or vertices, having the same angle between adjacent edges for every tile. The tessellations created by bonded brickwork do not obey this rule. Common ones are that there must be no gaps between tiles, and that no corner of one tile can lie along the edge of another. Tessellation in two dimensions, also called planar tiling, is a topic in geometry that studies how shapes, known as tiles, can be arranged to fill a plane without any gaps, according to a given set of rules. Tessellations form a class of patterns in nature, for example in the arrays of hexagonal cells found in honeycombs.Ī rhombitrihexagonal tiling: tiled floor in the Archeological Museum of Seville, Spain, using square, triangle and hexagon prototiles Tessellations are sometimes employed for decorative effect in quilting. Escher often made use of tessellations, both in ordinary Euclidean geometry and in hyperbolic geometry, for artistic effect. Historically, tessellations were used in Ancient Rome and in Islamic art such as in the Moroccan architecture and decorative geometric tiling of the Alhambra palace. Such tilings may be decorative patterns, or may have functions such as providing durable and water-resistant pavement, floor or wall coverings. A tessellation of space, also known as a space filling or honeycomb, can be defined in the geometry of higher dimensions.Ī real physical tessellation is a tiling made of materials such as cemented ceramic squares or hexagons. An aperiodic tiling uses a small set of tile shapes that cannot form a repeating pattern. ![]() A tiling that lacks a repeating pattern is called "non-periodic". The patterns formed by periodic tilings can be categorized into 17 wallpaper groups. Some special kinds include regular tilings with regular polygonal tiles all of the same shape, and semiregular tilings with regular tiles of more than one shape and with every corner identically arranged. In mathematics, tessellation can be generalized to higher dimensions and a variety of geometries.Ī periodic tiling has a repeating pattern. Escher portrayed realistic objects like fish, birds, and other animals, in his drawings and prints.Example of non‑periodicity due to another orientation of one tile out of an infinite number of identical tiles.Ī tessellation or tiling is the covering of a surface, often a plane, using one or more geometric shapes, called tiles, with no overlaps and no gaps. ![]() MC Escher is known as a master of tessellation artwork. Tessellations have been used for thousands of years in architectural designs and structures. ![]() The squares meet with no overlapping and can be extended on a surface forever. For example, a checkerboard is a tessellation comprised of alternating colored squares. Tessellations are connected patterns made of repeating shapes that cover a surface completely without overlapping or leaving any holes. He became known for his detailed realistic prints that achieved bizarre optical and conceptual effects. He was a draftsman, book illustrator, tapestry designer, and muralist, but his main work was as a printmaker. Maurits Cornelis Escher was a Dutch graphic artist born in 1898 who made mathematically inspired woodcuts, lithographs, and mezzotints.
