“…Traditional and digital surveying; CAD modeling (e.g., direct parametric modeling or reverse modeling based on digital surveying); mathematical computation (e.g., using algorithms for calculation of theoretical reconstruction); and a combination of these are the main techniques and tools used to achieve these goals using a commercial 3D CAD program. [31] The research describes a procedural way of decoding a 3D pattern (from its 3D actual geometry to its analysis) while also clarifying the rules that govern the construction of 3D patterns (from the 2D drawing to the 3D geometry). The research utilizes photogrammetric methodology for reconstruction and CAD-based modeling.…”

The history of Islamic architecture gives great features to the rich Islamic heritage through muqarnas, which formed interior spaces with their intricate and brilliant architectural ornaments. Muqarnas plays a central and vital role in aesthetic architecture, an element, which belongs to architecture and ornamentation. The geometric and ornamental analysis of Islamic art raises new interest in digital and algorithmic modeling, as well as new horizons in muqarnas formation. Muqarnases incorporate among their elements harmonious blocks and lines, and mathematical design, which perform a specific architectural function and an aesthetically ornamental role. The research seeks to link the originality of the past and the modernity of the future, in addition to studying the role of digital design, algorithmic systems, and various generative geometries in the evolution of the muqarnas, which is one of the progressive features of Islamic architecture. This study attempts to translate it into a modern language with innovative patterns and the effectiveness of their connection with digital and algorithm architecture. The paper presents an analytical study of traditional muqarnas patterns in Islamic art and their evolution by determining the logic and rules of muqarnas patterns using digital algorithms through digital design. In addition to controlling classical ornamental patterns of muqarnas by coding and programming in computational design. Thus, overcoming the gap between classical ornamental patterns and the flow of the digital design. The main concern is digital software which can be used to facilitate the design process and visualization of virtual models of muqarnas. The formation of three-dimensional muqarnases may provide new insights for mathematics to analyze the shape and create innovative patterns in the digital age. The problem with the study is that it does not clarify modern methods of digital algorithms in the discovery of a modern architectural style for Islamic art, which contributes significantly to enhancing muqarnas. This analysis encompasses the studies of muqarnases through concept and historical evolution as well as structural and algorithmic analysis, on the other hand. The research supplies a new approach to the characteristics of muqarnas through computational logic and establishes digital modeling of muqarnas through digital algorithms to produce different design patterns. The main concern of the research is to study the theoretical principles of digital algorithms for the identity of muqarnas through algorithmic rules and digital patterns. Therefore, we conclude the value of analyzing digital algorithms, which are often used to develop muqarnas, since Islamic architecture has endless possibilities for future design innovations. Therefore, this study firstly reviews earlier approaches to the analysis of geometrical and conceptual principles of muqarnas. Secondly, the research interprets the recommended scheme through a series of digital experiments and algorithmic forms. During these experiments...

PurposeThis study proposes a DfMA (Design for Manufacture and Assembly) based on unmanned aerial vehicle (UAV) and uses Iranian-Islamic Muqarnas as the main case study due to their geometric modularity. In Islamic architecture, different geographic regions are known to have used various design and construction methods of “Muqarnas”, a type of decorated dome.Design/methodology/approachThe paper presents a study on parametric analysis of the Iranian-Islamic Muqarnas and analyses its components, geometric relations and construction methods that should be considered when constructing one. This study aims to use the Muqarnas analysis as a driver to generate a DfMA basis on the UAVs and parametric fabrication. In Islamic architecture, different geographic regions use various design and construction methods of Muqarnas. There are four main parameters of the Muqarnas that define their classification; first, their three-dimensional shape, that provides volume. Second, the size of their modules is variable. Third, their own specific generative process-algorithm, and finally, the two-dimensional pattern plan that is used as a basis in the design. Thus, the authors present a global analytical study that drives a generative system to construct Muqarnas, through a careful balance of the four parameters.FindingsThis study thus presents a global analytical study that drives a generative system to construct Muqarnas, through a careful balance of four specifications. The paper reports the result of using a parametric tool, Grasshopper and parametric plugins, for creating a generative system of several types of Muqarnas. This synthetic translation aims at expanding our understanding of parametric analysis and synthesis of traditional architecture, advancing our understanding towards using parametric synthesis, with the scope to fabricate and assemble modules towards UAV-based fabrication of Muqarnas. To do so, the authors are taking advantage of their inherent repetition and recursion.Originality/valueIn the first step, this paper reviews studies on traditional Muqarnas (both Iranian and non-Iranian) and relevant parametric approaches. In the second step, the study aims to create a general generative system for Muqarnas. The creation of a generative system for Muqarnas is driven towards the creation of three-dimensional fabrication of their components so that these are assembled automatically using a swarm of UAVs. This particular drive imposes specific constraints in the parametric system, as the assembly of the final components, the authors posit, can only take place in a pick and place fashion.

“…The examples in Necipoglu's [14] and Uluengin's [13] books show stars with unequal edge lengths in muqarnas projection plans. Although the researchers such as Ozdural [15], Dold-Samplonius and Harmsen [16], Elkhateeb [17], Hamekasi et al [18], Castera [19], Kharazmi and Sarhangi [20], Gherardini and Leali [21], Kashef [22], Yaghan [23] and Takahashi [24] examined the structure of the muqarnas from various aspects, none of them focussed on the geometric reason for the unequal edge lengths of the stars in the muqarnas plans. Agirbas and Yildiz's previous study [25] is the first study related to the geometrical reason for unequal edge lengths of the stars in the muqarnas plans.…”

Interrelation between grid systems and star polygons of muqarnas ground projection plans

Many muqarnas ground projection plans contain stars with unequal edge lengths in their compositions. In this study, the geometric reasons behind the unequality of star edge lengths in muqarnas ground projection plans have been searched. The main gates with complex-looking muqarnas belonging to the period of Suleiman the Magnificent (Kanuni Sultan Suleyman), designed by Architect Sinan in Istanbul, have been selected to examine. From the data obtained by 3D laser scanning and from the verification made, it has been confirmed that there are stars with unequal edge lengths in these muqarnas plans. From the geometrical examinations made according to the shape grammar theory, it was concluded that the muqarnas plans were created using spider-web grid and square grid layouts. It was also concluded that these grid types cause some of the star edge lengths to be unequal.
