title	Irregular Vertex Editing and Pattern Design on Mesh
doi	https://doi.org/10.52842/conf.acadia.2011.278
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 278-283
summary	This paper introduces an innovative computational design tool used to edit architectural geometry by addressing the problem of irregular vertices. An irregular vertex is a special kind of vertex which is connected with fewer or greater less or more edges than regular vertices on a mesh object. Irregular vertices create problems with further surface rationalization, as well as structural analysis and constructability of the surface. Geometry created using other tools can also be remeshed upon import. Using the developed tool, the user is able to identify irregular vertices, interactively change the type, and then move or remove these irregular vertices. Additionally, a computational tool to make various design patterns on the mesh after the topology has been edited is also developed. The workflow is illustrated step by step in the pipeline. The advantages and disadvantages of editing mesh topology on architectural geometry design including the limitations are discussed at the end.

title	Implementations and Applications of DesignMap: Case Studies to Manage an Online Database of Visual Designs
source	International Journal of Architectural Computing vol. 6 - no. 3, pp. 243-258
summary	This research introduces state-of-the-art techniques in the areas of online libraries, communities, and forums. The research endeavours to describe a computer system called DesignMap that could be categorized as a visual design forum. This system encourages networking and can also be applied as a visual design library. The DesignMap system, which manages and displays a massive number of visual designs in two and three dimensions, was presented and discussed in a previous research. This project, however, is concerned with the application of DesignMap as a tool to search, visualize, modify, and then add designs in a map; these designs are classified based on their formal properties of object relationships. DesignMap users have access to any part or category in the map. The resulting design series created by users of this system present a new and unique form of design collaboration. The research also investigates several applications of the DesignMap system.

summary	This paper outlines the work and organizational framework of World16, a working group of 16 professors from around the world that engage in collaborative research on virtual reality (VR) technologies. Because of the abundance of VR software and the resulting fragmentation of research efforts in this field, World16 shares knowledge and resources using a common software package. A common research platform facilitates the sharing of data and the coordination of research efforts among member professors spread around the world. In addition to the organizational practices of World16’s project management team, various tools and methods of sharing research are described. Additionally, World16’s major research projects are outlined as well as the successes and failures of working within a shared software platform. Lastly, future work and goals of World16 are discussed, including the marketing and commercialization of several computational tools created by member professors.

title	Rapid SmartCode Modeling - Procedural Modeling for Urban Environments
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	This paper presents an image-driven method to rapidly generate 3D digital urban models for presentation in a real-time Virtual Reality (VR) environment. Several computational tools and methods are developed in order to give the end user the ability to transform a single 2D image into a realistically textured and rendered a 3D urban model. Using this method, city models based on SmartCode, a template for planning and urban design, are generated and presented in a VR visualization tool. The methods to generate VR city models including inputs, process, output, and pipeline are explained. One generated 3D city model is demonstrated in the results section.

title	Self-Organizing Map and Axial Spatial Arrangement: Topological Mapping of Alternative Designs
doi	https://doi.org/10.52842/conf.acadia.2006.342
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 342-355
summary	This research attempts to formulate a computational framework for exploring spatial arrangements in the early phases of design. In the physical world, this could be compared to exploring spatial arrangements using cardboard cut-outs or simply a grid of spaces on paper. This research demonstrates the framework by means of a generative design system that introduces axial order in a plan parti made up of discrete 3D objects. The tool is designed to organize the 3D objects along an Axis specified by the user and also rearrange them following user-defined mathematical expressions. The numerical parameters (the dimensions and physical properties of the individual objects) are linked through the mathematical expressions to vary the spatial arrangement of objects. Implementation of the tool involves the Self Organizing Maps (SOMs) as the Graphical User Interface (GUI) in generative systems. This allows the user to select and dynamically view spatial arrangements that have been organized on a map based on their similarity. The application is implemented, tested, and its results are demonstrated using buildings designed by Louis I. Kahn, Frank Lloyd Wright and Mies van der Rohe.

title	An Inductive Construction of Minimally Rigid Panel-Hinge Graphs and Application to Design Form
doi	https://doi.org/10.52842/conf.caadria.2014.493
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 493–502
summary	A panel-hinge framework is a structure composed of rigid panels connected by hinges. It was recently proved that for a so-called generic position, the rigidity of panel-hinge frameworks can be tested by examining the combinatorial property of the underlying graph. In this study, we apply such combinatorial characteristics to create design forms. However, such characterization is only valid for so-called "generic" panel-hinge frameworks. When considering the application of design forms, we need to take into account non-generic cases. In this paper, we develop the method to inductively generate non-generic rigid panel-hinge frameworks consisting of orthogonal panels and to inductively generate rigid panel-hinge frameworks based on fractal geometry coupled with space filling 3-dimensional convex polyhedron as a construction unit. We give examples of forms by the proposed method to demonstrate the applicability to design forms.

title	An Inductive Construction of Rigid Panel-Hinge Graphs and Their Applications to Form Design
source	International Journal of Architectural Computing vol. 13 - no. 1, 45–64
summary	A panel-hinge framework is a structure composed of rigid panels connected by hinges. It was recently proved that at a generic position, the rigidity of panel-hinge frameworks can be predicted by examining a certain combinatorial property of the underlying graph. In this study, we apply such combinatorial characteristics to create design forms. When considering the application of design forms, we must also take into account non-generic cases. In this paper we develop two new approaches; the first one that the method inductively generates non-generic rigid panel-hinge frameworks consisting of orthogonal panels and the second one that inductively generates non-generic rigid panel-hinge frameworks based on fractal geometry coupled with space-filling convex polyhedron as a construction unit. We will give examples of forms created by the proposed method in order to demonstrate the applicability of the proposed methods to design forms.

summary	This paper presents an algorithmic framework proposal for implementation of a multi-objective genetic algorithm (MOGA) in architectural design process. Different than the previous studies, we introduce a dynamic and extendible modular framework for multiple objectives. The objective modules with different fitness functions are connected simultaneously in the Rhino/Octopus interface, after multiplication with a constant value or a variable. In this study, we discuss the potentials and limitations of MOGA in 3D form generation, implications of MOGA in a case study and the qualitative and quantitative changes in relation to the change of constant value/ the impact ratio of competing objectives. The outcomes of the case study are investigated based on its potentiality in providing feedback in the earlier phases of decision processes in design.

summary	This paper aims to present a dynamic multi objective genetic algorithm (MOGA) framework for the purpose of generating 3D mass models in the context of housing design. The proposed MOGA framework contains static and dynamic modules such as regulations, environmental condition analysis as static, behavioral models, designer-specified goals, domain-specific goals based on building types as dynamic modules. Moreover comparison of two algorithmic approaches, implementation of a single and multiple objective genetic algorithms are compared in terms of variety and usability of the generated design solutions, fitness approximation performances and the speed of the algorithms (running time). In the scope of this study, the potentials andlimitations of the proposed MOGA framework in 3D form generation, its advantages over single objective genetic algorithm are discussed, conducted with a case study.

title	Exploration of Interrelationships between Digital Design and Production Processes of Free-form Complex Surfaces in a Web-Based Database
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 445-454
summary	The intention of this paper is to examine the mutual influences of initial architectural, structural and digital manufacturing related decisions on the evolution of free-form structures. A survey on current applications will be presented to lay the foundation for the examination of new production techniques and structural concerns for the computer generated expressive forms. Finally, the paper will describe an interactive web-based database project which aims to establish a grammar on the mutual influences of architectural, structural and production related features of free-forms. Based on the built examples of blob structures, the database serves as a catalogue of possibilities related to form, and facilitate assessment of the impact of the early choices on the free-form building design and development.

doi	https://doi.org/10.52842/conf.ecaade.2012.1.055
source	Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 1 / ISBN 978-9-4912070-2-0, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 55-65
summary	Learning in architecture has shifted from an individual focused approach to a larger system of interacting individuals in a situated, tool-mediated and socio-technical context. In addition to developing essential skills to work with diverse design software and taking part in collaborative design activities, learners also need to be equipped with competencies that will allow them to operate intelligently outside of situations of distributed cognitions. The challenge in present educational climate is to develop pedagogical approaches where situations of distributed cognition are not the ends themselves but are the means for improving mastery of solo competencies. The paper contributes to the current discussion about the need to re-orient architectural education and proposes a pedagogical framework for the development of a new web-based teaching/learning environment (socio-cognitive eco-system) as an integrated platform to support both autonomous and distributed learning.

title	Interdisciplinary Knowledge Modelling for Free-Form Design – An Educational Experiment
source	Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 465-474
summary	The recent advances in digital design media and digital fabrication processes have introduced formal and procedural effects on the conception and production of architecture. In order to bridge the individual concepts and processes of multiple design disciplines, intensive cross-disciplinary communication and information exchange starting from the very early stages of design is necessary. A web-based database for design learning and design teaching named BLIP is introduced. In this framework, cross-disciplinary domain knowledge becomes explicit to be taught and transferred in Free-Form Design research and education. BLIP proposes a conceptual map through which the user can construct structured representations of concepts and their relationships. These concepts are high-level abstractions of formal, structural and production related concepts in Free-Form design development. BLIP is used for formalizing, organizing and representing conceptual maps of the three domains and facilitates information and knowledge sharing in collaborative conceptual design in context. The paper introduces the application together with its application in two educational design experiments.

summary	This paper focuses on the emerging domain of digital free-form design, and attempts to explicate its knowledge content and characteristics through a systematic inquiry of the digital free-form design practice. The massive amount of information associated with the design and construction demands of the complexly shaped buildings demand explicit knowledge about the way various information pieces relate to one another. This paper reports on the process of developing a knowledge framework which serves as a reference model to describe and explain the free-form design and production processes in terms of the interaction of contextual conditions and according to the different ways design problems are perceived and formulated by the members of the design teams. The framework provides guidelines for the development of a web-based design decision support system to support collaborative knowledge construction, sharing and reuse in the domain.

title	Emerging Socio-Technical Networks of Innovation in Architectural Practice
source	International Journal of Architectural Computing vol. 11 - no. 1, 21-36
summary	This article reports on the initial analyses and findings of on-going research project which investigates the socio-technical transformation of Architectural practice due to technology adoption.A conceptual framework is developed as a tool to identify, analyse, and characterize the different socio-technical networks in current practice, and the ways in which these networks are being developed and coordinated. Highly technology- mediated and interdisciplinary architectural/engineering practices have been monitored and studied in their real-life project contexts.Through comparative case analyses, a conceptual framework has been developed and used to represent and analyse emerging socio- technical networks and the ways in which these networks facilitate innovation. In this context, new modes/practices of innovations are identified through the diverse and dynamic relationships emerging between architects, digital tools/systems, the design artefact, and the various multi-disciplinary knowledge/actors in a socio-technical setting.

title	Enhancing human-building interaction and spatial experience in cultural spaces
source	International Journal of Architectural Computing 2024, Vol. 22 - no. 2, 1-24
summary	In the realm of architectural evolution, the paradigm of static built environments has progressively shifted towards adaptive, responsive, and intelligent spaces. This paper presents a pioneering government-funded applied research project, the ‘Spatially Intelligent Arts Centre’, which exemplifies the convergence of multiple disciplines in the pursuit of redefining the traditional notion of a static arts centre. This endeavour sought to transform an existing arts centre building into a dynamic and intelligent space, thereby redefining its agency to foster novel user experiences and optimize operational efficiency. The project transcended conventional boundaries by merging the expertise of architects, computer scientists, user experience designers, spatial computing specialists, technology developers, and interface designers. Through transdisciplinary collaboration and adopting a design-thinking methodology, the project not only challenges the conventional limitations of architectural design but also offers a tangible illustration of the burgeoning field of human-building interaction research and practice. This paper details the conceptual underpinnings, technical implementations, and experiential outcomes of the Spatially Intelligent Arts Centre project, underscoring its significance as a model for implementation of human-building interaction in the context of a cultural building
