More than that, شیردهی they remind us of the underlying beauty and order of the cosmos. Past the transcendent beauty of a mosaic or engraving, tessellations discover functions throughout mathematics, astronomy, biology, botany, ecology, laptop graphics, materials science and quite a lot of simulations, together with highway methods. Other four-sided shapes do as nicely, including rectangles and rhomboids (diamonds). Polygons are two-dimensional shapes made up of line segments, corresponding to triangles and rectangles. Each level is enclosed by a polygonal cell -- a closed shape formed from line segments -- that encompasses your entire space that's closer to its defining point than to some other level. Instead of attempting this infinite calculation, they compute one answer for every Delaunay cell.
