summary	In this article the range of visual simulations for the competitive support is discussed and critically analysed by means of numerous definite competitions carried out within the working field of the authors – the range of experience concerning this matter covers a period of fifteen years (easily), all analysed examples were supported with the aid of CAAD/CAP-technologies. Recommendations are formulated and put forward for discussion. Furthermore the aspect of different acceptance of different presentational qualities (Levels of Detail) with the persons involved in the decision-making process are addressed (differences between socalled experts and laymen are particularly scrutinised).

title	Fabricating Ceramic Covers
doi	https://doi.org/10.52842/conf.ecaade.2005.269
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 269-276
summary	This paper describes a studio experiment developed with the aim of exploring the design and fabrication of innovative roof systems based on ceramic tiles using digital technologies. History is rich in examples of the use of ceramic roof tiles since the ancient world. Today’s systems derive from such ancient systems and fall into several basic categories depending on the form of the tiles and how they interlock. These systems present acceptable functional performances due to centuries of refinement, but as they have suffered little formal evolution in recent centuries, to respond to modern needs they require complex layering and assemblies. Recent technological evolution has emphasized the optimization of the tile production process in terms of time saving and cost reduction, and the improvement of product quality in terms of material homogeneity and durability. Little attention has been paid to the tile form and the roof system as a whole, including the assembly process. As a result, despite the variety and performance of existing designs, they are often perceived as outdated by architects who refuse to use them following a stylistic trend in architectural design towards primary forms and flat roofs. The challenge of the experiment was to take advantage of digital design and fabrication technology to conceive systems with improved performance and contemporary designs. The hope was that this could lead architects to consider integrating roof tiles systems in their architectural proposals. Results yielded five different roof systems. These systems are innovative from a formal viewpoint both at the tile and roof level. In addition, they are easy to assemble and possess better thermal and water-proofing performance. Digital technologies were determinant to enable students to design the complex shape of the tiles, to manipulate them into assemblies, and to assess the shape of the roofs, as well as their thermal and structural performance in some cases.

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	Dinamic architecture: the inclusion of digital media in architectural design process. A new reality?
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 385-389
summary	Until some years ago the discussion about the role of technology inside architecture was centered almost exclusively in the constructive environment. However with the development of digital technology, an impact has been generated on operations, design methods and working methodology, besides offering new possibilities to the architectural imagination. The technology of information has not only incorporated a series of new instruments but also an arsenal of methodological support resources to the designer, modifying the working model, it ways to perceive, anticipate and conceive an architectural project as it was traditionally made during centuries. Within this scenario, the changes hat would be taking place due to the inclusion of the digital media in the architectural enviroment, as much as in the “project language” as in the project process structure, integrating such concepts as movement, time and information, constitute the main reason of this investigation.

title	An Open Space with Scenery: ‘Greenscape Index’ for Performance Based Planning of High Density Urban Habitation
doi	https://doi.org/10.52842/conf.caadria.2005.328
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 1, pp. 328-334
summary	This paper presents an improvement of the original openness ratio concept, which has been formulated as an integrated index for early-stage urban open space planning and design support. The ‘greenscape index’ is a rating system which quantitatively integrates human visual perception with the visible landscape resources to evaluate the visual quality of open space vision within high-density urban environment. This new index is expected to provide more comprehensive environmental performance consideration criteria for urban planning and design. The research team also discusses the potential of the introducing this index to assess both psychological preference and physical form of urban open spaces. The new concept also has shown its feasibility on integrating key environmental considerations in visual sensitivity, urban wind, urban noise and solar heat gain into simple massing study which is applicable in the preliminary planning stage.

title	Interplay of Domains

summary	A diversified, open-ended, and critical approach of architectural design that interplays with a variety of media, suggests an innovative development to gain new spatial solutions. Architects and designers are aware of these possibilities by integrating physical and digital media during their design process, yet the creative potentials of these media are rarely used to their full potentials. The architectural design process can be enriched by using uncommon perceptions, comprehensions, and conceptions of spatial design translations within both physical and virtual environments. A wilful interplay with the design media and the process offers the possibility to dismantle the limits of each domain and explore the design itself in unorthodox ways. The overall engagement within both real and virtual environments leads to innovative form creations and powerful design solutions. Following the tradition of artists, who explore media in unusual ways, new architectural interpretations emerge, reflecting on the media as well as the architectural design.

title	Integrating Generative Modelling and Design Process
source	Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 77-88
summary	While researchers learn to generate design options with a computer, the question of how a designer interacts with these options remains largely unexcavated. This paper explores how a generative system should interact with a designer. It argues that limitations in human cognition require a designer to manage the complexity of his task with a creative thinking strategy called Perception-Imagination Overlay. To support this, a generative system should present a progression of contextual design “moves” rather than a collection of finished solutions. After validating a set of interface requirements, the paper presents an example interface. The paper concludes that the development of computational methods cannot be legitimately isolated from the development of an appropriate designer-system interaction, and that integrating these concerns might transform our conception of generative systems.

title	The Effect of Stereovision on the Experience of VR Models of the External Surroundings and the Interior of a Building
doi	https://doi.org/10.52842/conf.ecaade.2005.391
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 391-398
summary	Virtual reality offers considerable promise with regard to facilitating the building process. A good example is the facilitation of communication between architects and building companies, sellers and buyers or between community planners and the general public. It is often thought that in order to utilise the potential of VR in, for example, the above-mentioned contexts, it is necessary to use fully fledged versions of VR, including stereovision and the possibility of controlling the VR show. However, if a model can also be presented on less advanced equipment and still interpreted in a way that is useful to the viewer it will be possible to distribute the model simply and effectively. This would make it easier to create a more democratic urban planning process compared with if specialised equipment needed to be used and special shows needed to be arranged. In this study we compared the experience of two VR models (a large indoor exhibition hall and an outdoor street in Gothenburg, Sweden) when presented with and without stereovision. When the experience was measured using the Semantic Environmental Scale (the SMB scale, developed by Küller, 1975, 1991), questions on the experience of presence and six other questions on the experience of the models, the results only revealed one indication that stereovision made a difference. This indication was the result for the SMB factor Enclosedness. Suggestions are presented for future research in this area.

source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 438-443
summary	Throughout history, architecture has transposed contributions bound to structuralist focus or to musical composition. This is from linguistic and music respectively. New visualization systems show the possibility to give transpositions a new meaning, form the potentialities of hypermedia; locking for new projects parameters. This papers will show experimental workshop results developed within CI+D 2000 “New speeches and design process”. They study links and explore our work interrelating word – music and image. These processes are developed by people coming from literature, visual arts, music, and architecture areas. Lastly, the first results will be shown. Since parameters were transposed from music, by using NURBS forms, space prefiguration is tried out. [Full paper in Spanish]

title	Spatio-Temporally Navigable Representation and Communication of Urban Cultural Heritage
source	Proceedings: VSMM 2005 International Conference on Virtual Systems and Multimedia
summary	Virtual environments are effective tools for the representation and communication of cultural heritage. We suggest that an interactive, immersive and dynamic navigation of the virtual representation of the urban environment will not only convey the essence of the culture and the changes it underwent in a more comprehensible manner, but will engender a 'sense of place'—genius loci— in the visitors. This cognitive mode will help them learn about much more than the geometry and materiality of the city: it will make them 'feel' part of the event itself. By presenting a socially shareable experience, we aim to introduce the medium the character of a genuine place, and make it a social venue for active exploration, discussion and interaction. Virtual reality surpasses both traditional media and 3D-models and offers what they cannot. The affordances of the medium, however, also have the potential to destroy the sense of place it strives to engender. It can do so by allowing a kind of ‘time travel,’ to different periods in the history of the site. This ability locates visitors not only spatially, but also temporally. Everyday experience helps us understand the meaning of spatial boundedness, but does not prepare us to deal with temporal boundedness: sensing the presence of fellow visitors at different times. In this paper we describe our experiences in producing spatio-temporally navigable virtual reconstructions of two distinct culturally significant historic sites: the neolithic village of Çatalhöyük, and the medieval city of Cairo. We demonstrate the use of spatio-temporal navigation through a dynamic, chronologically layered model that can be browsed by multiple users at the same time. Such a dynamic system for representing chronological architectural events requires the extension of our conception of place into the temporal domain. We introduce a new concept, temporal field of view (t-FOV) and discuss how it can aid us in resolving an intrinsic challenge introduced by the representation of the temporal dimension in virtual environments.

summary	This paper investigates the impact of Tablet PCs on the workflow in an undergraduate design studio. We examined how well the students adapted the Tablet PC into their day-to-day design work and evaluated the appropriateness of the Tablet PC as a common digital tool used in an architectural design studio. This research involved observation of student behavior during the semester and the conducting of a survey measuring various aspects of the students’ use of the computers. A more specific goal was to compare the effectiveness of the pen versus the mouse as input devices for a three-dimensional modeling task in terms of both task time and strategies. Our assumption was that a change in input mode would affect the strategies and the performance. The results of a within-subjects, repeated-measures experiment carried out to elicit differences in input devices are discussed.

title	A Representation Language for a Prototype CAD Tool for Intelligent Rooms
doi	https://doi.org/10.52842/conf.acadia.2005.170
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 170-183
summary	Intelligent rooms are a type of intelligent environment which enhance ordinary activities within the confines of a room by responding to human interaction using pervasive and ubiquitous computing. In the design of intelligent rooms, the specification of how the intelligent room enacts intelligent behavior through computational means is as integral as the geometric description. The self-aware and context-aware capabilities of intelligent rooms extend the requirements for computer-aided design tools beyond 3D modeling of objects. This article presents a Hardware as Agents Description Language for Intelligent Rooms (HADLIR) to model hardware in an intelligent room as “hardware agents” having sensor and/or effector modalities with rules and goals. End-users describe intelligent room hardware as agents based on the HADLIR representation and write agent rules and goals in Jess for each hardware component. This HADLIR agent description and the requisite software sensors/effectors constitute “hardware agents” which are instantiated into a multi-agent society software environment. The society is then bridged to either a virtual environment to prototype the intelligent room or to microelectronic controllers to implement a physical intelligent room. The integration illustrates how the HADLIR representation assists in the design, simulation and implementation of an intelligent room and provides a foundation technology for CAD tools for the creation of intelligent rooms.

summary	Computer aided modelling and drafting protocols – in combination with new production technologies – have contributed to wholly new ways of shaping building elements. Some examples of new techniques, which have recently become very successful in building production and in architectural design education, are: 3D Rapid Prototyping; 2,5D and 3D Milling and computer aided Shape Cutting (notably using laser and water jet modes). Such new approaches not only create new opportunities for traditional production processes (including physical modelling), they also offer new perspectives for design and manufacturing on the level of architectural components and connections. We foresee innovative approaches to building product design, with a renewed interest in expressive Ornamentation. A phenomenological development we would like to address using the concept of ‘Ornamatics’. This contribution explores the potentials of product design with a renewed focus on ornamentation, involving the active utilization of computer aided modelling and manufacturing techniques. The paper furthermore documents results and findings of a series of explorative studies carried out within an educational laboratory environment.

summary	This paper presents the advancements of the Urbamedia project which was designed as part of a research program at the Center CAO (Creation computer assist), School of Architectural Design and Urbanism, University of Buenos Aires, which was led by the valued master and advisory professor Architect Arturo F. Montagu. This proposal of the city of Buenos Aires on the Mayo Avenue expands the original historical fragment presented between the following two referenced representative landmarks: The Two Congresses Square and the Mayo Square. It continues with the advancement of methodologies and techniques implemented in a system of “integrated visualization and communication” for the development of a VRML (Virtual Reality Modeling Language) 3D virtual non-immersive and interactive vision. It also incorporates the development of a “foundation of digitally integrated knowledge” with fragments of central areas from other surrounding cities as well as interfaced phenomenological situations. The application of digital VRML technology has allowed for thoroughly researching the processes through dynamic simulation of specific urban fragments (Mayo Avenue within Buenos Aires) and the cities that are also participating in the project.

summary	This paper describes how the application of interactive three dimensional computer modelling enables students of architecture to gain a comprehensive insight into how buildings are made. An intimate exploration of what can be, in the student’s perception, a lacklustre subject area is revitalized through the use of virtual building models and introduces the student to the potentials of this medium in communicating their own design work. In addition the published case studies are navigated as one would a web site which is a familiar and comfortable format for the student. Original working drawings and specification provided by architects are utilised in generating detailed three dimensional virtual models of the complete building along with larger scale detail studies of particular building components. The models are then animated or transferred to VRML format for publication within interactive case studies. The case studies may be accessed via the department server for use by staff during lectures and seminars or informally by the individual student.

title	Learning and Designing in a Virtual Place
doi	https://doi.org/10.52842/conf.ecaade.2005.303
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 303-309
summary	This paper reports on a study of the role of place in a virtual learning environment for digital media design. Using an immersive 3D Virtual World based on Active Worlds, we have created a virtual learning place for students in a Website Design course. The virtual learning place has two distinct parts: a classroom-like place surrounded by student galleries. Students can navigate and communicate (synchronous chat) within the environment in the form of an avatar (virtual person). We recorded the conversations and activities of the students in discussions held in the virtual learning place and applied a communication coding scheme to analyze their discussions. In this paper we present our approach to developing an understanding of the role of place and evidence of its effect on the conversations of design students in a virtual learning environment. We show how we identified the characteristics of place and specifically how it provides a context for identity and presence for supporting collaborative and constructivist student centred learning.

title	Fabrication with Residual Wood through Scanning Optimization and Robotic Milling
doi	https://doi.org/10.52842/conf.ecaade.2024.1.025
source	Kontovourkis, O, Phocas, MC and Wurzer, G (eds.), Data-Driven Intelligence - Proceedings of the 42nd Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2024), Nicosia, 11-13 September 2024, Volume 1, pp. 25–34
summary	The project deals with the use of residual wood of tree stumps and roots through scanning, optimization and robotic milling. Wood logging residue makes up to 50 percent of the trees harvested biomass. (Hakkila and Parikka 2002). Among prevailing strategies is leaving residue on site, and recovering residue for bioenergy. (Perlack and others 2005). The project explores the third strategy, using parts of the logging residue for fabrication, which may reduce the overall amount of wood logging volume. Furthermore approach aims for applying residue in its natural form and taking advantage of specific local characteristics of wood (Desch and Dinwoodie 1996). The project applies the strategy on working with stump and roots of an oak tree. Due to considerations of scale, available milling technics and available resources, chosen goal of the approach is to create a functioning chair prototype. Among the problems of the approach is the complex shape of the residue, uneven quality of wood, varying humidity and contamination with soil. After cleaning and drying, the stump is scanned and a 3D model is created. The 3D model od a stump is confronted with a 3D modelled limits of the goal typology (height, width, length, sitting surface area and overal volume of a chair) and topological optimization algorithm is used to iteratively reach the desired geometry. Unlike in established topological optimization proces, which aims for a minimal volume, the project attempts to achieve required qualities with removing minimal amount of wood. Due to geometric complexity of both stump and goal object, milling with an 6axis industrial robotic arm and a rotary table was chosen as a fabrication method. The object was clamped to the board (then connected to a rotary table) in order to provide precise location and orientation in 3D space. The milling of the object was divided in two parts, with the seating area milled in higher detail. Overall process of working with a residual wood that has potential to be both effective and present aesthetic quality based on individual characteristics of wood. Further development can integrate a generative tool which would streamline the design and fabrication proces further.

summary	This paper presents a recent experience related to the use of 3D digitization and digital modelling. This was done with the aim to bridge the gap between physical and digital models produced by students as part of their design development exercise. The paper examines the use of 3D digitization in architectural design education, by using both contact and non-contact scanning technology. The main aim was to translate physical models using 3-Dimensional digitization in order to create accurate digital copies. Finally, the paper discusses the results of the use of 3D digitisation and the digital modelling process, and assesses the benefit of this technology within an educational setting.

summary	This paper describes the usage of parametric design and evolutionary optimisation techniques in architect-engineer collaborations. It discusses the apparent challenges in setting up a trans-disciplinary working-platform that cuts across profession-specific boundaries and negotiates between the otherwise distinct work-methodologies through the use of intelligent CAAD applications. Two approaches to architectural form finding have been combined in this research. The first, parametric design, uses a proprietary package as a key element to the organisation and reorganisation of architectural design. By doing so, it is providing it with intrinsic flexibility allowing designers to go beyond form and accommodate performance data for versioning. The second, ESO (Evolutionary Structural Optimisation), is an engineering tool based on the use of finite element analysis (FEA) capable of optimising the formal geometry of an object to obtain minimum volume under even stress-distribution through an iterative design process. In undertaking this research it became apparent that different levels of resolution need to be addressed in the form-finding process in order to investigate the full potential of the interactive use of parametric design and evolutionary optimisation. The case studies reflect this diversity and demonstrate more successes, limitations and future challenges within the transdisciplinary, collaborative effort.
