summary This paper presents an application of swarm intelligence towards the problem of spatial configuration. The methodology classifies activities as discrete entities, which self-organise topologically through associational parameters: an investigation of emergent route formation and spatial connectivity based on simple agent and pheromone interaction, coupled with the problem of ‘loose’ rectangular geometric assembly. A concept model sniffingSpace (Ireland, 2009) developed in Netlogo (Willensky, 1999), which established the self-organising topological capacity of the system, is extended in Processing (Fry & Rea, 2009) to incorporate rectangular geometry towards the problem of planning architectural space.

summary This paper posits a design approach that integrates multi-agent generative algorithms and structural topology optimisation to design intricate, structurally efficient forms. The research proposes a connection between two dichotomous principles: architectural complexity and structural efficiency. Both multi-agent algorithms and Bi-directional evolutionary structural optimisation (BESO) (Huang and Xie 2010), are emerging techniques that have significant potential in the design of form and structure.This research proposes a structural behaviour feedback loop through encoding BESO structural rules within the logic of multi-agent algorithms. This hybridisation of topology optimisation and swarm intelligence, described here as SwarmBESO, is demonstrated through two simple structural models. The paper concludes by speculating on the potential of this approach for the design of intricate, complex structures and their potential realisation through additive manufacturing.

title The interdependence of linear and circular causality in CAAD research: a unified model

source Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 609-618
summary This paper discusses the relationship between linear and circular conceptions of causality and questions the common mutually-exclusive bivalent logic applied in distinguishing them. It argues that (circular) conversation and (linear) control both have their place in the design process. This calls for open minds and a reconsideration of value systems in CAAD practice and research, without which CAAD remains the futile attempt to deploy techniques developed to identify and enforce linear causation for the benefit of a practice that depends upon circular causality.

summary Graphic designers always take both time and efforts when they are creating a decorative pattern with complicated curves and a great deal of motifs. Although there are many sourcebooks of decorative patterns, the satisfaction of the results couldn’t accomplish with designer’s requirements. Thus, graphic designers need a faster and easier system to create decorative patterns in classical style. There are a few effiencient methods to analysis curves and surfaces in the development of shape grammars. The purpose of this research is to develop Vine Grammar based on shape grammars. The vine grammar analyses principles hidden in the language of deisgn works to create the order, then generates design by using Bézier curves. This research also presents the development of a decorative pattern generative system called Shlishi by using FLASH Action Script 2.0. The grammar can be applied with computers and to verify rules quickly by Shlishi. The intention of this research is to make graphic designers to use these rules to create decorative patterns of plants in classic style and to produce satisfactory results for designer more efficiently or to make the results the source materials for the follow-up design works.

title (In:)forming Interactive Architectural Systems, Case of the xMAiA Meta-model
doi https://doi.org/10.52842/conf.acadia.2010.203
source ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 203-210
summary This paper positions the domain of interactive architecture (iA) and searches for an appropriate model for structure and processing of information in the design and operation of such architecture. It is shown that there are different approaches to ways in which iA system models can be defined, each with numerous advantages and disadvantages. However, due to complexity of encountered problems, application of such models can be only partially validated by simulation and hence their design is inherently dependent on creation of operational and experiential full-scale prototypes of the systems these models represent. Another observation is the lack of correspondence between existing iA models and other contemporary models of computation for architectural geometry, fabrication and engineering. A meta-model for extensible multi-agent interactive architecture (xMAiA) is consequently proposed as a remedy to this situation. xMAiA meta-model is aimed to provide an open framework for integrated evolution, development and operation of interactive architectural systems. It delivers an extensible platform, in which diverse, project-specific models and approaches can be implemented, tested, and further evolved. Such a platform has the potential to empower agile development and operation of interactive architectural ecologies, as well as to substantially facilitate integration of creative design and experiential prototyping from day-1 of project design and development cycle. An example application conforming to the xMAiA meta-model is consequently presented and illustrated with a case study project performed in the university education context.

title Studying designers’ behaviour in collaborative virtual workspaces using quantitative methods
doi https://doi.org/10.52842/conf.caadria.2010.273
source Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 273-282
summary This paper presents a case study comparing the behaviour of designers in a collaborative 3D virtual environment with those in a face-to-face environment using quantitative tools to examine their design protocols. It starts with depicting a design ontology along with two methods of analysis for this investigation. The results in this case show that the 3D environment increases the designer’s Structure activities. The rate of meaningful design communication is slower than the base-line face-to-face session. This communication reflects the rate of design cognition when the design process is “close coupled”. Reviewing the design protocol suggests that the 3D design session composed of both “loosely coupled” and “close coupled” periods. This is consistent with other studies that 3D collaborative tools may encourage “loosely coupled” design process.

title Urban Space Planning for Sustainable High Density Environment
doi https://doi.org/10.52842/conf.ecaade.2010.777
source FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.777-785
summary In this paper we investigate the possibilities of new typologies of urban public space for high density environments. The premise for the project would be that with new high-density typologies, it would be necessary to consider a difference in the nature of urban public spaces rather than a difference in degree from the status quo. From observations of urban patterns that drive collective, hybrid spaces around Asia, relationships between urban attributes are drawn. For this paper we shall focus on the particular case of Linked Hybrid, Beijing, China, as an elevated urban public space. A literature review focuses on reviewing key theories to construct and adopt a rating system to develop an empirical framework to evaluate the case studies and extract the key attributes. These rated attributes are then abstracted in a real-time model that enables user manipulation. The purpose is to create a tool to better observe the effects and evolution of planning decisions for future urban spaces in high density contexts. The preliminary results are consistent with the idea that selected spatial parameters of a space may be embedded into a “barcode” and referenced as a type. The combination of different types, hence their parameters may be used for effective replication of their characteristics to improve the decision-making process for urban designers. The research is not intended to reproduce the successful urban public spaces but rather result in a catalogue of typologies which can be referred to during the initial stages of planning to provide an indication of spatial qualities.

summary This article presents the description and evaluation of a tangible interface to facilitate a collaborative work process. It starts with the concept of ambient display, which refers to the presentation of information in space or in an object through subtle changes. After describing the developed interface, some observations from the operation of the device are presented. We conclude that ambient displays should not be used as replacements to conventional tools, but instead, as complementary elements, and that it is also important to ensure their application as a method to restore a lost balance between tangible predispositions and the center of attention.

summary As smooth geometric shapes are very tricky to manufacture with an overall great expense this paper presents a parametrical approach how to control the joint geometry within a framework of flat panels which approximate a freeform surface using discretization. Since timber has an excellent reputation as a sustainable and regenerative material plus the fact that timber can be perfectly processed with a large variety of tools including CNC milling machines we are using cross laminated timber boards (CLT) with large and heavy members. Hence that means dealing with high forces which require geometrically exact and often complex joints, which we want to push to a high degree of automation in the design process. We establish rules and constraints between all neighboring CLT-panels. That way we control a new connector system specially designed for non-standard CLT-joints. This paper documents the status of one aspect of an ongoing research project and will also give a preview to upcoming tasks including the production of a prototype structure.

title Presence in Virtual Cave

summary Virtual Reality (VR) is usually recognized as a tool that enables the viewer to move freely in a three dimensional digital environment. In this virtual world, different levels of immersion could be reached. Using VR to visualize sites and places from the past, presents and future is widely acknowledged. This study is making use of a recently installed U-Cave theatre at Birzeit University (BZU) in Palestine and a Con-Cave VR theatre at the Norwegian University of Life Sciences (UMB).In the study, we test hypotheses connected to presence in virtual reality environments, using the case of historical sites. Historical sites in general are important for reasons of cultural identification and environmental integrity. In many historical sites, it is difficult for a layperson to read and understand the meaning of the site, for that the remaining ruins don’t provide enough information. This study will contribute to improving the public understanding for historical sites by unfolding the role of Virtual Reality to overcome the harsh reality of many damaged historical sites. The story-line of the site can be easily portrayed by re-constructing the original site in a virtual environment. The study also elaborates on the enriched sense of presence made possible by implementing different levels of details in the VR environment. Presence in VR environments is usually defined as “being there”, with high consideration of the physical ether of the virtual environment, the definition confines attention to the sensation of place. This study calls for expanding the attention to the dimension of time that is made possible by innovative design of VR environment. The study argues that virtual reality technology does not only provide a 3-D experience to subjects, it can also add a fourth dimension by conveying the unconsciousness of man from the meanwhile moment to a different timeframe. Based on the current knowledge on presence in virtual environments, we will use a questionnaire to measure subjective presence for the two VR theatre systems. The study will make use of the following factors in order to determine the degree of presence in the virtual environment: (1) naturalness of interface design and involvement, (2) control and interaction, (3) quality of technical capabilities, and (4) negative effects. The outcome of the study will verify or falsify some of the following hypotheses: • There is a correlation between modeling techniques and presence. The perception of the visual experience differs between traditional media and an immersive VR environment. • A presentation of a historical site in a VR-Cave environment will increase our subject’s awareness of the identity of the historical site. • The presence level is correlated to previous real exposure. Subjects who had been to a ruined historical site in real life, would experience higher level of presence toward the VR presentation than those who had not been to the historical site in reality. • Because of the display enclosure surround effect, it is believed that presence in a Con-Cave would be higher than of U-Cave VR environment.

summary This research asks the question of how the design knowledge production mechanism is processed differentiates digital design actors from each other in the social media/professional and academic fields of architecture. Due to the broad nature of the research question, the study focuses on academia and academia-related media through prominent architect-authors and subject titles in the literature. Bourdieu’s concept of capital is introduced, in which cultural and symbolic capital are considered part of the production values of digital design actors. Digital design actors use image-based social media tools such as Instagram effectively. The paper uses two methods: the first is a bibliographical analysis of author-texts, and the second is a social network analysis. By employing the keyword-based search from the Web of Science database, this study has managed to extract papers with full records (citations, keywords, and abstracts), with the journal Architectural Design having most publications. Considering that both academicians and professionals contribute to publications in Architectural Design, we selected all its publications between 2010-2020 for bibliometric analysis. These analysis techniques include the bibliometric network analyses and social network analysis with the focus on visualizing the algorithms and statistical calculations of well-established metrics. The research reveals the most critical nodes of the bibliometric network by calculating the appropriate central metrics. The network formed by the selected Instagram accounts of digital design actors are shown to be a small-scale network group, while the hashtags of digital design concepts are more numerous than the digital design actors.

summary This paper proposes a solution to the problem of digital image segmentation based on clustering techniques. K - means and fuzzy k - means are clustering algorithms detailed within this study. We propose novel modifications to k - means and fuzzy k - means algorithms to vary objective functions and to use color difference as a distance measure. These new algorithms are guaranteed to obtain the same results as the originals while considerably reducing the execution time. Pixel growing is used to obtain connected structures in the results of clustering algorithms.

summary Specialists and educators have proven the effectiveness of using case studies as a learning support method. In the teaching of architectural techniques some technologically - based tools have been developed that enable students to accumulate technical data from studied cases. Nevertheless, this way of presenting case studies to students has restricted their potential because it promotes design fixation, typification, and functional incoherence. A complementary TIC - based tool for case studies is presented here, which allows the relation of technical data to the dynamic situations that produce them. This new tool is designed to increase students´ analysis and design capacities, and turns accumulative technical data systems into integral technological tools for teaching architectural techniques.

summary The use of StyleGAN algorithms proposes a novel approach in the investigation of architectural images. Even though graphical outcomes produced by StyleGAN algorithms are far from being architectural spaces, they might become a starting point in the creative process of architectural projects. By creating a database of specific categories of architectural images located in certain contexts, significant findings might emerge regarding their categorization in accordance to the style of a culture. This research analyzes the architectural images that result from implementing StyleGAN algorithms in a database of images of Chilean houses built between the years 2010 and 2020 and selected as finalist of the ´Project of the Year´ from international viewers and curators of the most viewed architectural website of the world. Our findings suggest that Chilean houses have two distinctive elements strongly influenced by human bias: the proportion of voids in the architectural-like generative volume and the integration of vegetation or landscape.

In several workshops we tried to test how these young students would interact within a virtual environment configured for architectural needs. Providing a special setup equipped with a tracking system and sensors we investigated the children’s behaviour and the robustness of our system with regard to the education of elder students and further research.

title Emergent space diagrams: The application of swarm intelligence to the problem of automatic plan generation
source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 245-258
summary This work investigates how diagrams of architectural space might self-organize relative to specific associational parameters to generate diagrams of spatial organization. The premise is that buildings are systems of spatial relations defined by the dynamic interactions of various autonomous spatially discrete entities. Looking to swarm intelligence, the focus here is on the problem of circulation and explicit spatial arrangement. The paper reports an investigation of emergent route formation and spatial connectivity based on simple agent and pheromone interaction. An array of ant colonies defines the system. A colony’s nest represents a specific space. Space-agents transmit information throughout the space-colony population, defining an emergent communication network.
