Other prominent contributors include Alexei Vasilievich Shubnikov and Nikolai Belov (1964), and Heinrich Heesch and Otto Kienzle (1963). Fyodorov's work marked the unofficial beginning of the mathematical study of tessellations. Some two hundred years later in 1891, the Russian crystallographer Yevgraf Fyodorov proved that every periodic tiling of the plane features one of seventeen different groups of isometries. He wrote about regular and semiregular tessellations in his Harmonices Mundi he was possibly the first to explore and to explain the hexagonal structures of honeycomb and snowflakes. In 1619, Johannes Kepler made an early documented study of tessellations. ĭecorative mosaic tilings made of small squared blocks called tesserae were widely employed in classical antiquity, sometimes displaying geometric patterns. Tessellations were used by the Sumerians (about 4000 BC) in building wall decorations formed by patterns of clay tiles. History A temple mosaic from the ancient Sumerian city of Uruk IV (3400–3100 BC), showing a tessellation pattern in coloured tiles Tessellations form a class of patterns in nature, for example in the arrays of hexagonal cells found in honeycombs. 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. GlTexGend(GL_T,GL_TEXTURE_GEN_MODE,GL_OBJECT_LINEAR) Īlso, remember that tessellating every frame is still not a good idea for anything but small tests, rather using it together with display list or VBOs as stated previously would be more effective.An 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. GlTexGend(GL_S,GL_TEXTURE_GEN_MODE,GL_OBJECT_LINEAR) You should remove the glTexCoord2d() calls and this has to go into the draw function: //adjust these values to the object/texture size For a more modern version, look at this Thread.

This is some old deprecated code, that probably still works for you but is very unreliable especially if you use shaders. You might also have to define the GLU_TESS_COMBINE callback, look here and here for details and more sample code.Įdit2: Actually texturing is not quite so easy. In order to give every vertex a texture coordinate, you need to write your own function that takes a void *(which will contain a pointer to the x,y,z coordinates of the vertex) and calls glVertex and glTexCoord.Īlso you should avoid doing tesselation every frame, so you should either save the calls between gluTessBeginPolygon and gluTessEndPolygon in a Display list, or better yet have your GLU_TESS_VERTEX function save the vertices in a VBO.

So here is my code for the front wheel arch.

Im learning to use openGL and iv been told that because my wheel arches are concave i have to tessellate them.
