  1. Uniform tessellation

    In geometry , a uniform tessellation is a vertex transitive tessellations made from uniform polytope Facet mathematics facets . All of its vertices are identical and there is the same combination and arrangement of faces at each vertex. An n dimensional uniform tessellation can be constructed on the surface of n spheres, in n dimensional Euclidean space, and n dimensional hyperbolic space. Nearly all uniform tessellations can be generated by a Wythoff construction , and represented by a Coxeter Dynkin diagram . The terminology for the convex uniform polytopes used in uniform polyhedron , uniform polychoron , uniform polyteron , uniform polypeton , uniform tiling , and convex uniform honeycomb articles were coined by Norman Johnson mathematician Norman Johnson . Wythoffian tessellations can be defined by a vertex figure . For 2 dimensional tilings, they can be given by a vertex configuration listing the sequence of faces around every vertex. For example 4.4.4.4 represents a regular tessellation, a square tiling , with 4 squares around each vertex. In general an n dimensional uniform tessellation vertex figures are define by an n 1 polytope with edges labeled with integers, representing the number of sides of the polygonal face at each edge radiating from the vertex.

  1. Centroidal Voronoi tessellation

    In geometry , a centroidal Voronoi tessellation CVT is a special type of Voronoi tessellation or Voronoi diagram s. A Voronoi tessellation is called centroidal when the generating point of each Voronoi cell is also its mean center of mass . It can be viewed as an optimal partition corresponding to an optimal distribution of generators. A number of algorithms can be used to generate centroidal Voronoi tessellations, including Lloyd s algorithm for K means clustering . Gersho s conjecture, proven for one and two dimensions, says that asymptotically speaking, all cells of the optimal CVT, while forming a tessellation, are Congruence geometry congruent to a basic cell which depends on the dimension. ref citation first1 Qiang last1 Du first2 Desheng last2 Wang title The Optimal Centroidal Voronoi Tessellations and the Gersho s Conjecture in the Three Dimensional Space journal Computers and Mathematics with Applications issue 49 year 2005 pages 1355 1373 ref In two dimensions the basic cell for the optimal CVT is a regular hexagon .

  1. Prototile

    File Penrose Tiling Rhombi .svg thumb 240px This form of the Penrose tiling has two prototiles, a fat rhombus shown blue in the figure and a thin rhombus green . In the mathematical theory of tessellation s, a prototile is one of the shapes of a tile in a tessellation. A tessellation of the plane or of any other space is a cover of the space by closed set closed shapes, called tiles, that have disjoint sets disjoint interior topology interiors . Some of the tiles may be congruence geometry congruent to one or more others. If mvar S is the set of tiles in a tessellation, a set mvar R of shapes is called a set of prototiles if no two shapes in mvar R are congruent to each other, and every tile in mvar S is congruent to one of the shapes in mvar R . It is possible to choose many different sets of prototiles for a tiling translating or rotating any one of the prototiles produces another valid set of prototiles. However, every set of prototiles has the same cardinality , so the number of prototiles is well defined. A tessellation is said to be monohedral if it has exactly one prototile. A set of prototiles is said to be aperiodic if every tiling with those prototiles is an aperiodic tiling . The three dimensional Schmitt Conway Danzer tile is the prototile of a monohedral aperiodic tiling of three dimensional Euclidean space , but it remains open whether there is a monohedral aperiodic prototile for the plane.

  1. Hypercell

    In geometry , a hypercell is a descriptive term for an element of a polytope or tessellation , usually representing an element one dimension higher than a Cell geometry cell . The most generally accepted term is Face geometry 4 face because it contains a 4 dimensional interior. Another proposed name in use is teron, shortened from tetron, constructed from the prefix tetra meaning four. A 5 dimensional polytope 5 polytope or Four dimensional space 4 dimensional tessellation can be considered constructed of 4 dimensional hypercells, 3 dimensional Cell mathematics cells , 2 dimensional faces, 1 dimensional edges, and 0 dimensional vertices. For example the 5 dimensional penteract 5 hypercube is constructed from 10 tesseract ic hypercells. Also the 4 dimensional tesseractic honeycomb is constructed from tesseract hypercells. In the context of these figures, hypercells can also be called Facet mathematics facets representing the highest dimensional elements of the figures.

  1. Weighted Voronoi diagram

    In mathematics, a weighted Voronoi diagram in n dimensions is a Voronoi diagram for which the Voronoi cells are defined in terms of a distance defined by some common metrics modified by weights assigned to generator points. The multiplicatively weighted Voronoi diagram is defined when the distance between points is multiplied by positive weights. ref name deza Dictionary of distances , by Elena Deza and Michel Deza http www.google.com books?id Xe2AZS6NcVAC&pg PA255&dq 22weighted voronoi diagram 22 pp. 255, 256 ref In the plane under the ordinary Euclidean distance , the multiplicatively weighted Voronoi diagram is also called circular Dirichlet tessellation ref Peter F.

Bolker, Generalized Dirichlet tessellations http www.springerlink.com content j334537p07370405 , Geometriae Dedicata , Volume 20, Number 2 , 209 243 doi 10.1007 BF00164401 ref ref Note Dirichlet tessellation is a synonym for Voronoi diagram . ref and its edges are circular arc and straight line segments. A Voronoi cell may be non convex, disconnected and may have holes. This diagram arises, e.g., as a model of crystal growth , where crystals from different points may grow with different speed. Since crystals may grow in empty space only and are continuous objects, a natural variation is the crystal Voronoi diagram , in which the cells are defined somewhat differently. The additively weighted Voronoi diagram is defined when positive weights are subtracted from the distances between points. In the plane under the ordinary Euclidean distance this diagram is also known as the hyperbolic Dirichlet tessellation and its edges are hyperbolic arc and straight line segments. ref name deza References reflist External links http www.whitman.edu mathematics SeniorProjectArchive 2005 dobrinat.pdf A review Category Discrete geometry Category Geometric algorithms Category Diagrams ...   more details



  1. Regular Division of the Plane

    Italic title Image Escher, Regular Division of the Plane III.jpg right frame Regular Division of the Plane III , woodcut, 1957 1958. Regular Division of the Plane is a series of drawings by the Netherlands Dutch artist M. C. Escher which began in 1936. These images are based on the principle of tessellation , irregular shapes or combinations of shapes that interlock completely to cover a surface or plane. The inspiration for these works began in 1936 with a visit to the Alhambra , a fourteenth century Moors Moorish castle near Granada , Spain . Escher had visited the Alhambra once before in 1922 but in this visit he had spent several days studying and sketching the ornate tile designs there. In 1958 Escher published his book The Regular Division of the Plane . This book included several woodcut prints to demonstrate the concept, but the series of drawings continued until the late 1960s, ending at drawing 137. While not Escher s most artistically important works, some of these patterns are among Escher s most famous, having been used for a number of commercial products, including neckties.

The colored circles. which represent the interpolating weights, w sub i sub , are generated using the ratio of the shaded area to that of the cell area of the surrounding points. The shaded area is due to the insertion of the point to be interpolated into the Voronoi tessellation Natural neighbor interpolation is a method of spatial interpolation , developed by Robin Sibson . ref cite book last Sibson first R. editor V. Barnett title Interpreting Multivariate Data year 1981 publisher John Wiley location Chichester pages 21 36 chapter A brief description of natural neighbor interpolation Chapter 2 ref The method is based on Voronoi diagram Voronoi tessellation of a discrete set of spatial points. This has advantages over simpler methods of interpolation, such as nearest neighbor, in that it provides a more smooth approximation to the underlying true function. The basic equation in 2D is math G x,y sum n i 1 w if x i,y i math where math G x,y math is the estimate at math x,y math , math w i math are the weights and math f x i,y i math are the known data at math x i, y i math . The natural neighbour method proposes a measure for the computation of the weights, and the selection of the interpolating neighbors The natural neighbor method utilizes the change to the Voronoi tessellation to compute weights. The weights, math w i math , are by utilization of the area stolen from the surrounding points when inserting a new point into the tessellation. Each weight may be computed by dividing the section of the new tessellated region that lies within the tessellated region of each original neighboring tessellated polygon.

  1. Metamorphosis II

    Artwork image file Escher, Metamorphosis II.jpg title Metamorphosis II artist M. C. Escher year 1939 1940 type woodcut height metric 19.2 width metric 389.5 metric unit cm Italic title Metamorphosis II is a woodcut print by the Netherlands Dutch artist M. C. Escher . It was created between November, 1939 and March, 1940. This print measures convert 19.2 x 389.5 cm and was printed from 20 blocks on 3 combined sheets. Like Metamorphosis I , the concept of this piece is to morph one image into a Tessellation tessellated pattern and then slowly alter that pattern eventually to become a new image. The process begins left to right with the word metamorphose the Dutch language Dutch form of the word metamorphosis in a black rectangle, followed by several smaller metamorphose rectangles forming a grid pattern. This grid then becomes a black and white checkered pattern which then becomes tessellations of reptiles, a honeycomb, insects, fish, birds and a pattern of three dimensional blocks with red tops. These blocks then become the architecture of the Italian coastal town of Atrani see Atrani, Coast of Amalfi . In this image Atrani is linked by a bridge to a tower in the water which is actually a rook piece from a chess set. There are other chess pieces in the water and the water becomes a chess board. The chess board leads to a checkered wall which then returns to the word metamorphose .
