A generative approach based on fractals in architectural design

Günümüz mimarlık ürünlerinin oluşturulmasında farklı tasarım yaklaşımları kullanılmaktadır. Kavramsal anlamda çok farklı olgulardan başlayarak sıradışı formların üretildiği mimari örneklere sıkça rast-lanmaktadır. Yeni tasarım örneklerinin bu yöndeki gelişimi farklı geometrik kurgulardaki formların, dijital tasarım ortamlarında betimlenerek üç boyutlu modellerinin üretilmesi ile desteklenmektedir. Bu çalışmada belli bir mimari dile ait biçim sözlüğünde bulunan elemanların fraktal kurgusunda var olan ilkeleri kullanarak bilgisayar ortamında mimari tasarımda ve mimari biçimlerin üretilmesinde yol gösterici olabilecek bir yaklaşımının geliştirilmesi amaçlanmıştır. Bu yaklaşım, mevcut bir mimari dokunun fraktal boyutuna ve özelliklerine dayanarak yeni formların üretilmesinde yaratıcılığı destekleyici üretken bir tasarım yaklaşımıdır.   Anahtar Kelimeler: Mimari tasarım, bilgisayar destekli mimari tasarım, fraktal geometri, üretken yaklaşım.Nowadays, different design approaches are being used in the formation of architectural products. Beginning with very different facts in the conceptual sense, examples of architecture produced by unusual forms are often encountered. The development of new design examples in this direction is supported by the production of forms in different geometric perceptions and of three dimensional models defined in digital design situations. In this study, by using the principles existing in the fractal perception of the elements found in a vocabulary relevant to a certain architectural language, an approach is suggested which will be able to show the way to computer aided architectural design and production of architectural forms. This approach, by relying on the fractal dimension and features of an existing architectural pattern, is a generative design approach supporting creativity in the generation of new forms. With the generative model formed by this approach, and by looking at the reality of architectural design from a different point of view, an attempt has been made to examine how fractal geometry may be used as a tool in architectural design. In the study, the place of fractal geometry within the scope of shape grammar and how it can be of benefit to the process of architectural design from a computer - aided design approach are examined. Keywords: Architectural design, computer aided architectural design, fractal geometry, generative approach

Global Teamwork: A Study of Design Learning in Collaborative Virtual Environments

With the recent developments in communication and information technologies, using Collaborative Virtual Environments (CVEs) in design activity has experienced a remarkable increase. In this paper we present a collaborative learning activity between the University of Sydney (USYD), and the Istanbul Technical University (ITU). This paper shares our teaching experience and discusses the principles of collaborative design learning in virtual environments. Followed by a study on students’ perception on the courses and collaborative learning in both universities, this paper also suggests future refinements on the course structure and the main areas of collaborative design learning.

Personalized transportation model proposal to support micromobility between public spaces

Kentte bir buluşma noktası olan kamusal alanlar, farklı bireylerin karşılaştıkları ve birlikte zaman geçirdikleri yerlerdir. Bu alanlara ulaşım seçenekleri ise bireylerin değişen taleplerine göre her zaman aynı olmayabilir. Tercihlerin aynı olmaması ve aynı seçeneğe yönlendirilmemesi de kamusal alan kullanımında çeşitliliğin sağlanması için oldukça önemlidir. Bu nedenle çalışmada, kamusal alanların kent içinde önemli duraklar olduğu kabul edilerek, iki kamusal alan arasında kişiselleştirilmiş bir ulaşım modeli önerilmiştir. Çalışmada yöntem olarak Analitik Hiyerarşi Süreci ve Bayes Ağları kullanılmıştır. Analitik Hiyerarşi Süreci yönteminde değerlendirilecek olan ulaşım seçenekleri, mikromobilite çalışmaları kapsamında ele alınmıştır. Bisiklet, elektrikli scooter ve yürüme eylemi için örnek rotalar oluşturulmuştur. Rotaların tercihini belirleyen kriterler için literatür incelemeleri yapılmış ve eşik değerler çıkarılmıştır. Ancak kullanıcıların farklı tercihlerine göre kriterlerin önemi ve buna bağlı olarak da rotaların uygunluğu da değişebilmektedir. Bu nedenle kriterlerin ağırlığının belirlenmesinde kullanıcı tercihlerinin dinamik değişkenliğini gözlemleyebileceğimiz Bayes Ağları modele dahil edilmiştir. Kullanıcıların tercihlerine göre, Bayes Ağları ile kriterlerin ağırlıkları belirlenmiş ve bu kriterler Analitik Hiyerarşi Süreci ile değerlendirilmiştir. Bayes Ağları ile kriterlerin ağırlıklarının belirlenmesi Analitik Hiyerarşi Süreci yönteminde verilerin tutarlılığını sağlamış ve sistemi daha esnek hale getirmiştir.Public spaces are a meeting point in the city, where different individuals meet and spend time together. Transportation options for these areas may not always be the same due to the changing demands of individuals. It is important that the preferences are not the same and not directed to the same option in order to ensure diversity in the use of public space. For this reason, in the study, a personalized transportation model between two public spaces is proposed. Analytical Hierarchy Process and Bayesian Networks are used as methods in the study. The transportation options that will be evaluated in the Analytical Hierarchy Process method are discussed within the scope of micromobility studies. Sample routes have been created for cycling, electric scooters and walking action. Literature reviews have been made for the criteria determining the choice of routes and threshold values have been removed. However, the importance of the criteria and the suitability of the routes may also change according to the different preferences of the users. For this reason, Bayesian Networks, where we can observe the dynamic variability of user preferences in determining the weight of the criteria, are included in the model

In-vehicle personalized routing for a heterogeneous group: An experience-based method for decision support system

Customized navigation devices allow personalized routings based on user preferences. In determining common preferences for multi-user, it may become di cult to meet at a common point due to conflict of interests. A decision support system could serve as an asset to increase the quality of decisions users take. In conventional systems, decision making ties to pre-defined preferences of a single user or a homogeneous group

Bodily and Spatial Dimensions of the Architectural Design Process in the Digital Age within Embodiment of Experience

In today’s digital epoch, existing design interfaces are insufficient for the generation of abstract and conceptual ideas by designers in early phases of the design process. This is despite the rapid spread and wide adoption of digital design tools and methods over the past two decades. Traditional design tools such as sketching and physical modeling maintain their importance in modern digital design studios, which may indicate a gap between the potential of digital media and its realization. This gap cannot be properly understood by merely considering it as a problem of tools and interfaces. In order to gain a holistic insight, we need to factor in the body, which perceives and interacts in-the-world through sensory-motor experiences and cognitive processes. In this study, we explore the role of embodied bodily experience on the constitution of abstract and conceptual ideas. We use both Lakoff and Johnson’s concept of “image schema” and McNeill’s classification of gestures to examine a thirty-minute case study involving two postgraduate architecture students. The aim of this study is to explore whether there are repetitive patterns in the iconic and deictic gestures during the modeling process as the participants generate spatial ideas. We aim to enrich the discussion on the role of bodily experience during architectural design and modeling by using the outcomes of this case study

Interactive Parametric Design and Robotic Fabrication within Mixed Reality Environment

In this study, a method, in which parametric design and robotic fabrication are combined into one unified framework, and integrated within a mixed reality environment, where designers can interact with design and fabrication alternatives, and manage this process in collaboration with other designers, is proposed. To achieve this goal, the digital twin of both design and robotic fabrication steps was created within a mixed-reality environment. The proposed method was tested on a design product, which was defined with the shape-grammar method using parametric-modeling tools. In this framework, designers can interact with both design and robotic-fabrication parameters, and subsequent steps are generated instantly. Robotic fabrication can continue uninterrupted with human–robot collaboration. This study contributes to improving design and fabrication possibilities such as mass-customization, and shortens the process from design to production. The user experience and augmented spatial feedback provided by mixed reality are richer than the interaction with the computer screen. Since the whole process from parametric design to robotic fabrication can be controlled by parameters with hand gestures, the perception of reality is richer. The digital twin of parametric design and robotic fabrication is superimposed as holographic content by adding it on top of real-world images. Designers can interact with both design and fabrication processes both physically and virtually and can collaborate with other designers

Transformations created by ICKT on the architectural design and its education

Information, communication and knowledge technologies (ICKT), creates serious economic, social and cultural transformations in the contexts of human, human life and space. Architectural design and its education is one of the fields seriously influenced by the ICKT. In the case of architectural design and its education, the influences of ICKT are not only in relation to the technological side of it but the subject is far more complex as it has a social, cultural and economical aspects. Architectural design and production processes, its tools, concepts, theories, methods and forms are highly affected by ICKT and the transformations have begun. Digital technologies are challenging theories and practices of traditional architectural design both from educational and practical perspectives. Standing at the threshold; one should consider the technologies beyond themselves with all the transformations that they cause. This process of questioning ICKT and architectural design relationship should only be started at the architectural educational platform where experimental, theoretical and practical sides are always present. Questioning the boundaries of the discipline, re-conceptionalizing it and re-defining its role in the future are the subjects to be discussed in educational platforms. Architectural discipline should update itself to protect its own realm of being, its cultural validity and its meaning. Furthermore, a new more creative and complex way of teaching architectural design could be find in this mutual relationship of ICKT and architecture
