Seamless Patterns

The square, the triangle and the hexagon
A Module “it’s the basic unit that allows to compose 2-D or 3-D structures by repetition" The square, the triangle and the hexagon are the only forms which fill the plane without leaving gaps, in a seamless way. Miguel Sánchez. Graphic Design for 2º ESO

We can find several examples of seamless patterns in our everyday life.
Cellular structures of living beings. Textile design. Urban patterns

Too many artists have used the modules and networks to create their works…

Pentagonal tilings 14 types of pentagonal tilings with irregular pentagons have been discovered Ms. Marjorie Rice discovered four of them. She is not a professional mathematician, but a housewife who makes some very nice quilts! Miguel Sánchez. Graphic Design for 2º ESO

A mysterious tessellation: Durero's Pentagons

Durero’s fractals

The modular space: FACTORS
1.-CREATION OF THE MODULE 2 .- DISTRIBUTION IN A NETWORK 3.- COLOR CHANGE

The modular composition
Modular networks are geometric structures that relate modules REGULAR: They use a single regular polygon that is repeated. Triangular grid Repetition of a equilateral triangle. Grid Repetition of a square Hexagonal grid Hexagon recurrence SEMI-REGULAR: They use two or more regular polygons

Semi-regular Two conditions 1 - All polygons have equal sides
2 - The sum of the angles of polygons around a nodule is worth 360 º Miguel Sánchez. Graphic Design for 2º ESO

IRREGULAR: modules disposed in different shapes and varied resources.
Rectangular. Ravine . Rhomboid Radiated COMPOSITION FROM A RED TRIANGLE . Composite Hexagon

Super-and sub-modules
OVERLAP: This consists of networks or modules mounted on top of each other for more complex structures Overlapping Kamal Ali’s Module Super-and sub-modules

By resources of symmetry. By turns.
To repeat the modules, we use dynamic geometry based on the composition of motions in the plane: By resources of symmetry. By turns. Giro de 30º Moving modules. And so, proceed to fill, or not, all the compositional plane Miguel Sánchez. Graphic Design for 2º ESO

Geometry and Algebra in Moorish art
The Mosaics of the Alhambra Geometry and Algebra in Moorish art

These decorative motifs are found almost everywhere in the Alhambra in Granada

The Koran prohibits any iconic depiction of Allah.
The main reasons of this explosion of geometry in the Spanish-Muslim art are found in religion The Koran prohibits any iconic depiction of Allah. Divinity is identified with the singularity.

Y efectivamente comprobamos al observar todos estos mosaicos
que ningún punto es singular ni más importante que los demás.

Lo que se mueve en el plano son polígonos regulares, de tal forma que:
No quede espacio ninguno del plano sin cubrir. No se superpongan unos polígonos con otros.

They can cover the plane with figures that are not regular polygons…

The answer is simple: the figures used come from regular polygons
How did they get that? The answer is simple: the figures used come from regular polygons Just turn them properly.

The “Nazari Bone" is obtained by deforming a square:

The "petal" is obtained by deforming a diamond:

The " Nazarí bow" is obtained by deforming a triangle:

The flying fish The Nazarí dove

Although it seems that there are many structures in these mosaics, everyone adjusts to 17 different models. These models were investigated by Fedorov in the late 19th century, and it was the mathematician who proved that any tiling of the plane is a set of one of these 17 configurations.    And here we have them all:
