If you have a given repeating pattern, you can slide it along a certain direction a certain distance and it will fall back upon itself with all the patterns exactly matching. (Self-similar fractals have symmetries on different scales, and so other transformations must be considered to understand them.) There are four kinds of planar isometries: translations, rotations, reflections, and glide reflections. The only transformations that we'll consider are those that preserve distance, called isometries. We can identify a symmetry as a transformation of the plane that moves the pattern so that it falls back on itself. We're interested in the symmetries of a planar pattern. Symmetries of patterns are transformations Penrose Rectangle RGB Ritme altern Ritme creixent Ritme decreixent Ritme unifrome Salvador Dalí Scribbling lines Scumble lines Skateboard Stippling Teorema de Tales Tessellation Triangle Vasilij Kandinskij Vince Low W.E.Wallpaper Groups: transformations Transformations of the plane Escher Marcel Duchamp Mark Rothko Miguel Endara Mirada fèrtil Ombrejat Pablo Picasso Pentàgon Percebre Percepció Pes visual Polígon Proporció. lusions òptiques Intercept Theorem Joan Brossa Joaquim Chancho Joseph Jastrow José María Yturralde Jurament dels Horacis La textura M.Escher Capgrossos Carnestoltes Claude Monet Color llum Color pigment Colors complementaris Colors primaris Colors secundaris Colors terciaris Composició Comunical visual Cross hatching CYMK Còmic Descomposició Dibuix tècnic Edouard Manet English Equilibri visual Escala Film Formes geomètriques Formes orgàniques Fotografia Geometria Hatching Heptàgon Hexàgon Iconicitat Icònica Il Etiquetes Abstracta Akioshi Kitaoka Antoni Tàpies Arts & Crafts C.For example, in Gravity, multicolored turtles poke their heads out of a stellated dodecahedron. Escher’s artwork is especially well liked by mathematicians and scientists, who enjoy his use of polyhedra and geometric distortions. Many of Escher’s works employed repeated tilings called tessellations. These feature impossible constructions, explorations of infinity, architecture, and tessellations.Īlthough Escher did not have mathematical training-his understanding of mathematics was largely visual and intuitive-Escher’s work had a strong mathematical component, and more than a few of the worlds which he drew were built around impossible objects such as the Necker cube and the Penrose triangle. He is known for his often mathematically inspired woodcuts, lithographs, and mezzotints. Maurits Cornelis Escher usually referred to as M. These videos show how to do tessellation using paper and scissors, a easy way to make tessellations: These were described by Escher.Ī translation is a shape that is simply translated, or slid, across the paper and drawn again in another place. There are 4 ways of moving a motif to another position in the pattern. The term has become more specialised and is often used to refer to pictures or tiles, mostly in the form of animals and other life forms, which cover the surface of a plane in a symmetrical way without overlapping or leaving gaps. They were used to make up ‘tessellata’ – the mosaic pictures forming floors and tilings in Roman buildings The word ‘tessera’ in latin means a small stone cube. Tiling: When you fit individual tiles together with no gaps or overlaps to fill a flat space like a ceiling, wall, or floor, you have a tiling. A tessellation is created when a shape is repeated over and over again covering a plane without any gaps or overlaps.Īnother word for a tessellation is a tiling.
