A SHAPE GRAMMAR MODEL TO GENERATE ISLAMIC GEOMETRIC PATTERN
Ebru Ulu, Sinan Mert ŞENER: A SHAPE GRAMMAR MODEL TO GENERATE ISLAMIC GEOMETRIC PATTERN. In: Generative Art 2009.
Geometric patterns are the important ornaments of Islamic art and architecture. Polygons and poly-pointed star patterns, especially the 6-, 8-, 10- and 12-sided polygons were mostly used in Islamic art and architecture. They have created various geometrical compositions on the surfaces. The 10 sided polygon, decagon, is a special shape in Islamic geometry. This study is evaluating the special features of decagons in Islamic art by analysing the Penrose tiles, aiming the generation of new patterns that have the similar characteristics of the geometric patterns in Islam with the help of a shape grammar model. In this context, two design templates developed are for the new generated patterns.
In this paper, the combinations of the bowtie and the elongated hexagon, which are the sub shapes of a decagon, are mentioned and generated to make it possible to cover a rectangular surface. Two bowtie-elongated hexagon templates help to generate new forms. They are related to Islamic geometrical patterns and many results of the generation from these two templates are given in the framework of this study.
The aim of this paper is to show that different final products can be formed from the shapes, which have the same design language and same initial shape applying the same rule schema. It is clarified that a design can be handled at a wider perspective in the context of shape grammars and reproduced by the new designs with the same genetic features.
The future goal of this research is to apply this shape grammar model and the design templates with a computer program, in order to get the results easier and faster.
