Najaar 2017
Dit patroon op een isometrisch grid ontwierp ik najaar 2017. De zevenhoeken zijn regelmatig, de andere vijf vormen hebben minstens één symmetrie-as.
Het patroon behoort tot een in de Islamitische ontwerptraditie schaars voorkomende symmetriegroep met drievoudige rotatiesymmetrieën, maar zonder zesvoudige.
Hieronder een pdf in zwartwit van hetzelfde ontwerp.
Voorjaar 2014
Threefold rotational symmetry around both the big and the small sixpointed stars and reflection symmetries in three directions.
This pattern belongs to a newly discovered category of patterns that belongs to a wallpapergroup that was very scarcely used in Islamic design.
This is a part of the same tessellation consisting of sixpointed stars (two sizes), fivepointed stars, hexagons (three types which have almost equal shapes) and, in the middle, a tile with the shape of an incomplete star and a hexagonal empty space in the middle.
With these seven different tiles the plane can be tessellated.
Spring 2014: A late-fourteenth century design with tens and sevens
(This pattern was my own design, late fourteenth century on the Islamic calendar.)
Multiple-design of a pattern with octagons
These patterns were designed with the use of drawing in a 16th century manuscript. In this drawing, a subgrid consisting of two types of hexagons is used resulting in a pattern with regular heptagons. I made use of the same subgrid to design patterns with regular octagons. (feb 2014)
Winter 2014: Design of a pattern with 4-, 7-, 8- and 16-pointed stars
This tessellation suggests the possibility of combining these various 'perfect' stars in this way. However, the stars aren't exactly regular! There are small imperfections making this combination possible.
Mathematically speaking: The 16-pointed stars do not have an exact 16-fold rotational symmetry and the 7-pointed stars do not exactly have 7-fold rotational symmetry.
These types of mosaics, with slight irregularities were produced in the Seljuk period (11th-13th century Persia) also. Mr Peter Cromwell wrote an article about this, to be published in 2014.
Persian-style geometric pattern designed by students in may 2012
Two students Daphne de Ridder and Thomas Mast from Texel who did the course on Islamic patterns won the Texel 2012 design competition. Their work is reproduced electronically in triplex. Therefore I drew their design using 'Geogebra'. The result is shown here. The colourful end result of the students (They called their work 'Lente', meaning 'Spring') can be found at leerlingen presenteren hun werk.
The pattern has a typical Persian style and it wouldn't surprise me if the design was made before during the middle ages in the Persian region thus making the student's design a 'reinvention' of a pattern designed centuries ago. Its basic pattern consists of squares, hexagons and dodecagons hence the many four-, six- and twelvefold local or total rotation symmetries.
Here's a photograph of the mosaic in triplex. I published a series of photo's showing the production process at van leerlingontwerp naar kunstwerk.
Summer 2012: Design of a pattern with regular heptagons
Spring 2012: Persian-style geometric pattern
With the drawing programme 'Geogebra' I designed this Persian-style pattern with regular eight- and ninepointed stars. The pattern has reflection and glide reflection symmetries, four- and twofold rotational symetries and local eight- and ninefold rotational symmetries. Besides the two starshaped tiles there are three other types of tiles. Two of them have one axis of symmetry, the third one has two axes of symmetry.
For information about the design technique used and in case you wish to use this design for any goal, please contact me.
