title	Mindful Spaces: Computational Geometry and the Conceptual Spaces in which Designers Operate
source	International Journal of Architectural Computing vol. 5 - no. 4, pp. 611-624
summary	Combinatorial computational geometry, while dealing with geometric objects as discrete entities, provides the means both to analyse and to construct relationships between these objects and relate them to other non-geometrical entities. This paper explores some ways in which this may be used in design through a review of six, one-semester-long design explorations by undergraduate and postgraduate students in the Flexible Modeling for Design and Prototyping course between 2004 and 2007. The course focuses on using computational geometry firstly to construct topologically defined design models based on graphs of relationships between objects (parametric design,) and concurrently to output physical prototypes from these "flexible models"(an application of numerical computational geometry). It supports students to make early design explorations. Many have built flexible models to explore design iterations for a static spatial outcome. Some have built models of real time responsive dynamic systems. In this educational context, computational geometry has enabled a range of design iterations that would have been challenging to uncover through physical analogue means alone. It has, perhaps more significantly, extended the students' own concept of the space in which they design.

title	Multi-touch - the future of design interaction
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 557-572.
summary	The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

title	Emergent Form from Structural Optimisation of the Voronoi Polyhedra Structure
source	Proceedings of the Generative Arts conference, Milan, 2007
summary	In the course of the exploration of computational means in the architectural design process, in order to investigate more complex, adaptive geometries, the Voronoi diagram has recently gained some attention, being a three-dimensional space-filling structure which is modular but not repetitive. The project looks at the Voronoi diagram as a load-bearing structure, and whether it can be useful for structural optimisation. Hereby the edges of the Voronoi polyhedra are regarded as structural members of a statical system, which then is assessed by structural analysis software. Results seem to indicate that the Voronoi approach produces a very specific structural as well as spatial type of order. Through the dislocation of the Voronoi cells, the statical structure becomes more complex through emergent topology changes, and the initially simple spatial system becomes much more complex thorough emerging adjacencies and interconnections between spaces. The characteristics of the emerging form, however, lie rather in the complexity how shifted spaces and parts are fitted together, than in a radical overall emergent geometry. Spatially as well as a structurally, the form moves from a simple modular repetitive system towards a more complex adaptive one, with interconnected parts which cannot stand alone but rather form an organic whole.

title	The Bishopsgate Tower Case Study
source	International Journal of Architectural Computing vol. 5 - no. 1, pp. 62-81
summary	This paper summarizes the ongoing research on the Bishopsgate Tower in the City of London designed by Kohn Pedersen Fox Associates. We present a pre-rational geometry computational solution targeting a constraint-aware exploration of the architectural design-space, while interactively optimizing building performance in terms of constructability and cost-efficiency. We document a novel approach in building metrics optimization supported by parametric technologies and embedded analytical algorithms. The process is indicative of how computational methods will develop in the future and help designers find solutions for increasingly complex spaces.

title	Parametric Design and Structural Optimisation for Early Design Exploration
source	International Journal of Architectural Computing vol. 5 - no. 4, pp. 625-643
summary	The investigation presented in this paper focuses on the following questions: How can engineering and architectural expertise, assisted by a process of digital optimisation, promote structural awareness regarding design alterations in the conceptual design stages? Can building geometry be set up computationally to render it sensitive to structural input? Which software tools are required to foster this interaction and what kind of decision support is needed to allow both architects and structural engineers to interact concurrently in this optimisation process? The authors of this paper form a team of researchers and practitioners from architectural and structural engineering background who combine their efforts to address the issue of interconnecting design intelligence across disciplines and advancing revised work methodologies in practice assisted by academic research. The research has shown that an integrated transfer of design information between architectural and structural designers in the early stages is beneficial to the collaboration if experts from both professions agree on common goals and define suitability rules that guide optimisation processes from the very beginning. To enable this, software tools are required that provide ad hoc decision support to create a wider array of informed design alternatives from which to choose.

summary	The investigation presented in this paper focuses on the following questions: How can engineering and architectural expertise guide a process of digital optimisation and add structural ‘awareness’ in real time to aesthetic considerations (or vice versa)? How can building geometry be set up computationally in order to render it ‘sensitive’ to structural input? Which tools are required to foster this interaction? The authors of this paper form a team of researchers and practitioners from architectural and engineering background who combine their efforts to address the issue of interconnecting design intelligence across disciplines and advancing work methodologies in practice assisted by academic research. A live case study project is presented as a test scenario in order to find answers the above questions.

title	Teaching Digital Design Exploration: Form Follows
source	International Journal of Architectural Computing vol. 5 - no. 4, pp. 685-702
summary	This paper presents some challenges of teaching computational geometry to architectural students, and proposes a multi-level pedagogical scheme introducing associative geometry and parametric modeling/design into architectural design education. It reports on two pedagogical experiences: one held in the context of a spatial geometry course in the first year of education; and another one, in a digital design studio with third-year architectural students. More specifically, it discusses the impact on design exploration of a library of interactive referents models introduced into the architectural studio. Situated in the 'performance' paradigm of digital design methods, they allow for design object explorations based on modification of architecturally meaningful features (structural, environmental, functional, etc.). The form of a design object can thus 'follow' function, structure, or even sustainability. The digital methods and the design knowledge transferred by the interactive models, together with their visual nature, are found to amplify the processes of 'seeing-as' and the 'reflective conversation with the situation' considered essential for creative design.

title	Geometry, Light, and Cosmology in the Church of Hagia Sophia
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 304-319
summary	Designed by a physicist and a mathematician, the Hagia Sophia church in Istanbul, Turkey acted as an experimental test case in which advanced knowledge of geometrical constructs, sophisticated understanding of light behavior, and religious and cosmological beliefs combined to create a magnificent structure. While some of its design concepts are known, many remain hidden. Earthquakes have demolished parts of the church—such as the original dome. Researchers have in the past misinterpreted their observations and perpetuated false conclusions. Lastly, the lack of digital tools has until now prevented verification and analysis of prior findings. In this paper, we integrate traditional historical research, parametric digital analysis, and lighting simulation to analyze several aspects of the church. In particular, we focus on the geometry of the floor plan, the geometry of the apse, and light behavior in the original dome. Our findings point to the potential of digital tools in the discovery of a structure's hidden features and design rules.

doi	https://doi.org/10.52842/conf.ecaade.2007.901
summary	The increasing trend in architecture to create unconventional forms opened up a new area of investigations in the employment of computational methods in design and construction. Our investigation is undertaken within a structural engineering firm, Adams Kara Taylor and focuses on finding ways to design structural solutions that respect criteria of efficiency, architectural intentions as well as intrinsic properties of the geometry. In this paper, we present various approaches on discretization where a project is presented as a continuous form, envelope or skin that must be subsequently subdivided in order to yield a framing or cladding solution compatible with different manufacturing, design and engineering considerations. The first part of this paper illustrates such a project where we applied and developed one of our discretization approaches. The second part of the paper focuses on generalization where we present a series of methodologies and corresponding software tools developed for the purpose.

title	Parametric Form Finding in Contemporary Architecture
source	Vienna University of Technology; Building Science & Technology
summary	The search of new geometry has been during the last years an interesting subject for Contemporary Architecture. As the 21st century brought a new era for architectural design, CAD programs have evolved together with the idea of Form Finding. The possibilities offered make the collaboration of the architect with the computer now possible in terms of searching the appropriate form for given cases. As the analysis of contemporary architectural pieces has indicated, the procedure of architectural design can be semi-automated. Parametric Form Finding is transferring generative approaches into the architectural design workflow by introducing a set of rules to describe the constrains of the form. Given this context, two methods have been realized, which are guided by the user by providing basic two dimensional shapes, restrictions and form characteristics. The approach is fitted in a plug-in for the modeling environment of Rhinoceros that generates three dimensional form based on the user?s input. The methods followed are being evaluated.

title	Plan_B: The architectonics of sonic information
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 587-594
summary	The paper addresses the influence of digital technology on architectural design and production, particularly considering the possibilities of sound for the design and conception of architecture based on the dynamic condition, which is present in the “everyday” and its permutations. The day-to-day condition is regarded as a highly dynamic flux of economic, social and political aspects and conceptually linked to sound and musical variation as guiding design principles, to actually retain and reflect the vitality of every day’s measure. We have traced precedents and cases in sound reproduction and its implications on the codification of architecture and have created a digital design tool in Max/MSP. The primary objective of the tool is to produce the corollary between sound reproduction and the conception and production of an architectonic codification, and ultimately to propose a strategy of architectural construct that has given way from the clarity of static geometry to the complexity in dynamic variability, that of dissonance. Virtual architecture and its techniques are considered to express and implement such permutations and induce a measure of change in every step and direction of the design process. The application of digital technology is regarded as the intervening of “apparatus” and to represent a different approach in relation to the prevailing regime.

title	Embodying Architectural Form and Space by Coupling Computer and Human Performance Using Motion Capture Technology: Study on Application of Motion Capture to Design Process for Generating New Geometry
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 757-766
summary	This research aims to develop fundamental design methodologies for human space and product design by motion capture of human activity. It is intended to generate new geometry using a motion capture system as design input device and then to develop it to design interior space and products such as furniture from data extracted from human motion. In order to produce a ubiquitous and comfortable environment, performance modeling focusing on the relationships between space and physical motion is needed. Making an object of complex shape is thought to be a new application of motion capture technology. This research proves that the numeric data of body actions can be transferred and developed to object shapes.

title	A Framework for the Design of Kinetic Façades

summary	The particular requirements of kinetic façades are discussed in relation to a general model for future CAAD research – a 3D digital prototype based on (1) the concurrent evaluation of quantitative and qualitative performance over time (2) the calibration of geometry and physics to materiality and mechanics. Concurrent performance in the case of kinetic façades is determined by the dual role as environmental screens and the socio-cultural function as the public face of architecture. From these principles a framework is proposed that informs the conceptualisation of software that will address unique requirements - the design of façades as process systems that perform over a range of time scales.

doi	https://doi.org/10.52842/conf.ecaade.2007.195
summary	This paper proposes a computational method for visualizing animated human reactions to physical conditions that are described in a synthetic architectural model. Its goal is to add a sense of place to the geometry, and augment the representation of its spatial quality for designers and audience. Spatial qualities in architectural design cannot be fully evaluated solely by observing geometrical constructs without reference to inhabitants placed inside. However, imagining what happens to those inhabitants and appreciating their movement is difficult even for trained architects. The proposed method introduces a walking scale figure in a geometric model. Through agent-based computation, it moves inside the model and displays various behaviors in reaction to spatial characteristics such as transparent surface, opaque surface, perforation and furniture. This method lays a foundation for developing a new kind of software that overcomes the shortcomings of current design tools.

doi	https://doi.org/10.52842/conf.caadria.2007.x.g6n
summary	This paper presents research on the relationship between digital tools and design communication, focussing on the interaction between architectural and lighting design. Early design integration often involves negotiating between different levels of resolution to inform a design that is still in formation, and part of the challenge is doing so in a manner appropriate to that phase of exploration. This paper describes some of the technical and social issues of translation and reports a project in which a generative design process supported the interaction between architectural design and lighting analysis; domains in which geometry is not necessarily a common ground.

title	Get Real Towards Performance-Driven Computational Geometry
source	International Journal of Architectural Computing vol. 5 - no. 4, pp. 663-684
summary	In historic design conventions geometry has traditionally promoted descriptive manifestations of form. Beyond the realm of geometry, the concept of performance which may inform such manifestations also carries important potential for design generation. This work explores the relation between geometry and performance from a computational-geometry perspective. It does so by revisiting certain analytical tools offered in most of today's 3-D modelers which support the evaluation of any generated surface geometry specifically curvature and draft angle analysis. It is demonstrated that these tools can be reconstructed with added functionality assigning 3-D geometrical features informed by structural and environmental performance respectively. In the examples illustrated surface thickness (as a function of structural performance) is assigned to curvature values, and transparency (as a function of light performance) is assigned to light analysis values. In a broader scope this work promotes a methodology of performance-informed form generation by means of computational geometry. Vector and tensor math was exploited to reconstruct existing analytical tools adapted to function as design generators.

summary	The paper unfolds the association between geometry and material behaviour, specifically the elastic properties of resin impregnated latex membranes, by means of homogenizing protocols which translate physical properties into geometrical functions. Resinimpregnation patterns are applied to 2D pre-stretched form-active tension systems to induce 3D curvature upon release. This method enables form-finding based on material properties, organization and behaviour. A digital tool developed in the Processing environment demonstrates the simulation of material behaviour and its prediction under specific environmental conditions. Finally, conclusions are drawn from the physical and digital explorations which redefine generative material-based design computation, supporting a synergetic approach to design integrating form, material and environment.

source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 112-116
summary	This paper develops the topic of morphological generation of artificial landscapes using digital media. Current trends in landscape composition link architectural style to ground topography; buildings are not simply placed on the land, instead, they emerge from it, generating alternative morphology landscapes, or so-called “topographic landscapes” that emerge from the massive incorporation of computer technology in the design process, and are supported by the complex organization of topologic geometry. There has been a change from the classical method of architectural composition, in which rather than linking diverse shapes together in a static layout, dynamic actions inspired by the landscape are linked instead.
