Rule for Generating Islamic Star Patterns
With Shape Grammer Methods



In the 1970s, they created new form derivations with the shape grammar and rule sets used by Stiny and Gibs as the form generation method. Conventional production methods were later used in design with many disciplines.


With the help of the discipline of shape grammar, Islamic geometric patterns, which are the subject of the study, have been tried to be produced with rules. Until today, many people have tried to draw Islamic geometric patterns with different rules. In this study, it has been tried to formulate the regular Islamic rosette and star patterns with ten, six, eight and twelve arms after examining their formal and drawing features. In addition, the set of rules was revealed by using the unit triangle arising from the number of arms and angular relations in drawing rosettes or stars. In the first part, after the aim, scope and method of the study were explained, in the second part, the historical development of the subject of Islamic art, the architectural works with geometric patterns and the ornamental arabesque were mentioned on a period basis and examples from history were tried to be introduced.


The formal features of the patterns were tried to be explained through the architectural ornamentation examples of the Early Islamic period and the Umayyads, Abbasids, Anatolian Seljuk and Ottoman states. On the basis of other design disciplines, besides architecture, examples of geometric forms seen in certain areas such as ceramics, tiles, carpet-weaving, and calligraphy are also shown. In this way, the characteristics of arabesque, which is an ornamental art, were tried to be understood through Islamic art.


In the next section, after the definition of language and its regular set grammar, the definition of morphology and examples in different disciplines where it is used are given. After giving examples of the productions created by Kaplan, Salesin, Lee, Abas and Salman, in which shape grammar is applied on Islamic geometric shapes, seven frieze groups derived linearly from symmetry and symmetry groups and seventeen wallpaper groups derived from x and y axis are explained. Islamic patterns as template creation are studied and exemplified by drawings by Ostromoukhov, Schattscheider, and Kaplan.


In the fourth chapter, a new production style has been tried to be created with the shape grammar rule of the star-armed badges. The unit triangle drawn depending on the number of arms establishes an angular relationship in the creation of stars and rosettes. The rosette motif is thought and drawn as two separate parts, the star in the center and the ring around it. In the next stage, the production of badges and stars with irregular arms and different angles is shown with rule sets. As a result, the motifs in the new forms created in this section could be created with the number of arms and angular differences. It is aimed to create the produced rosette and star motifs together. The design logic is to create the new with modern tools by taking the old as a reference.


The next step was to create my own templates using these symmetry groups. The next step after the creation of these templates was to fill them with various rosette or star motifs. Motifs that can be arranged at different angles can be embroidered on the template.


Finally, it is aimed to add different meanings and perceptions to the pattern with the line thicknesses, gaps at the intersections and coloring of the patterns created. In the last part, the conclusion part, a general evaluation of the study was made and information was given about how a program that could be produced in the future could be, and the study was concluded.
