title “Otra Andria” e-learning environment for the architectural designing workshop
source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 350-354
summary This work describes results obtained from a test over an experimental prototype “Otra Andria” (OA1) designed by the investigation team of “Obra Abierta: Over the construction of an investigating and learning system in virtual environments”. OA1 is a basic tool. It show us: three simultaneous screens with editing tool bars, an integrated chat for publication and discussion, images and texts, all this in synchronized time. Tools are simultaneously accessible from all boards by the teacher, the students or between pupils. There is a web log, a personal web, and an activities’ organization space for the professors. This experience was helpful to understand the actual needs for virtual environment applications as well as e-learning problems in such cases where the know-how is not available to every attendant to the course. That means we must begin working on hyper-medial language diffusion among all teachers who want to use the ICT in all its actual potentiality. [Full paper in Spanish]

title Applying Scientific Simulation to Integrate Thermoelectric Conductor Module into Architectural Design – Smart Wall for Thermal Comfort
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. 200-210
summary This paper presents the innovative architectural design concept, which is to integrate the new material and technology into the building design to achieve the thermal comfort and at the same time reduce the energy consumption of the building by making use of the renewable energy, including solar and wind energy. The system is developed based on the idea of regional thermal comfort in building. The advantage of the system is the environmental friendly approach, costless operation, reliability, flexibility, scalability and adaptability for the integration to the building design. With the design concept, we tried to do two application designs in two virtual sites. One is a badminton court for the 2008 Beijing Olympic Games and the other is a cooling pond in a shopping mall. We will introduce how computational simulation can contribute to the prediction of the performance of the design. We will also discuss how the computation simulation can help in the design optimization process. Through the development of the new design integration of the material to the building, we would like to feedback to the material industry to encourage further collaboration and development in the material enhancement, so that both industries and the society can benefit from the advancement.

title VISION OR RETROSPECTION INTO THE PAST: SCIENTIFIC VISUALIZATION IN THE RECOVERY OF PATRIMONIAL URBAN SPACES
source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 700-706
summary This paper shows the use of digital means in the presentation and relation between the perception of those who have walked by in the past and circulate at present through the Baralt Square space, at specific historic periods, with the purpose of reconstructing the different urban scenarios, and foresee their future, through the use of scientific visualization. The digital reconstruction of the square, of colonial origin, is a complex process. This multifunctional space represented forms and types of societies, as the various actors participated with perceptions and perspectives which were apart from reality, imposing their vision and interests, defining themselves in the materialization of the space-site. This research originates the urban analysis and the interpretation of the public space with the help of input devices and real-time visualizers. Interaction, virtual surroundings and mixed reality technologies may contribute in designing tools for the recovery of patrimonial surroundings. [Full paper in Spanish]

title Interfacing the Real and the Virtual: User Embodiment in Immersive Dynamic Virtual Spaces
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. 171-180
summary This paper discusses the performative boundary between the real and the virtual as it constitutes itself based on the potentials, conditions and abilities of Virtual Reality (VR), considered as both a technology and a medium. Starting from the prospects and the areas of application of 'new' technologies within the context of architecture, the paper seeks the point of intersection between an architectural perspective, a posthuman view and a technological potential. The focus thereby lies in the greatest challenge of VR, that is, the integration of the users as they interface the virtual and the real. The conditions and implications of such dynamic processes, perceived as space generating, rather than representing, are explored based on the authors' virtual environment: Uzume.

title From CAD to VR – Implementations for Urban Planning and Building Design
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 399-405
summary At present time, three-dimensional objects are often represented with 2D-data in urban planning and building design. In order to get all the involved parties to fully understand a certain project, this may not be enough. More and more projects therefore take use of the Virtual Reality (VR) technique as a complement to traditional 2D drawings and sketches. All the involved parties can then share a common frame of reference for all discussions regarding a certain project. Unfortunately, the technique is not yet adapted to fit the current building design process. In this paper, we present a solution for semi-automatic generation of a VR-model based on 3D CAD information and aerial photos obtained from the City Planning Authorities in Sweden. The data is imported to support real-time editing of terrain, roads and buildings. We also present a framework for importing 3D-models created in Autodesk Revit which enables a seamless integration of modern 3D CAD and VR-models. The features are implemented in a software developed at Chalmers Visualization studio (Gothenburg, Sweden) and technical details about terrain handling and speed-up techniques will be given.

title Baking Light: Global Illumination in VR Environments as architectural design tool
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. 2, pp. 214-228
summary As proven in the past, immersive Virtual Environments can be helpful in the process of architectural design (Achten et al. 1999). But still years later, these systems are not common in the architectural design process, neither in architectural education nor in professional work. The reasons might be the high price of e.g. CAVEs, the lack of intuitive navigation and design tools in those environments, the absence of useful and easy to handle design workflows, and the quality constraints of real-time display of 3D models. A great potential for VR in the architectural workflow is the review of design decisions: Display quality, comfortable navigation and realistic illumination are crucial ingredients here. Light is one of the principal elements in architectural design, so design reviews must enable the architect to judge the quality of his design in this respect. Realistic light simulations, e.g. via radiosity algorithms, are no longer the domain of high-end graphic workstations. Today's off-the-shelf hardware and 3D-software provide the architect with high-quality tools to simulate physically correct light distributions. But the quality and impression of light is hard to judge from looking at still renderings. In collaboration with the Institute of Computer Graphics at our university we have established a series of regular design reviews in their immersive virtual environment. This paper describes the workflow that has emerged from this collaboration, the tools that were developed and used, and our practical experiences with global-light-simulations. We share results which we think are helpful to others, and we highlight areas where further research is necessary.

title Envisioning the RESPONSIVE milieu: An investigation into aspects of ambient intelligence, human machine symbiosis and ubiquitous computing for developing a generic real-time interactive spatial prototype
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. 421-432
summary The research paper exemplifies upon a design-research experiment conducted by the Hyperbody research group (HRG), TU Delft, Faculty of Architecture under the supervision of the Author and Prof. Kas Oosterhuis (director HRG and ONL). The research work, specifically aimed at developing a real-time interactive spatial prototype, fostering multiple usability of space: ‘The Muscle Re-configured’. The ensuing Muscle Re-configured project is essentially an architectural design research undertaking maneuvering on the precincts of augmented and virtual reality, exemplifying a fusion between the material and the digital counterpart of the architectural domain. This fusion is attained through harnessing a synergistic merger between the fields of ambient intelligence, control systems, ubiquitous computing, architectural design, pneumatic systems and computation (real-time game design techniques). The prototype is visualized as a complex adaptive system, continually engaged in activities of data-exchange and optimal augmentation of its (system’s) components in accordance with contextual variations.

source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 293-299
summary As information technology continues to evolve, it is affecting all creative art forms by providing new tools and surroundings, such as virtual environments. 3D real-time simulation environments strongly support communication and navigation, enabling users to collaborate on designs using centralized or distributed environments. The persons concerned must understand the proposed design. Systems that help them gain this understanding are therefore required. An effective concept for gaining understanding is comparison. However, comparing one design proposal with another using existing systems is difficult because the users must consider their viewpoints separately. In this paper, we describe the concepts, strategies, and functions of a 3D virtual design environment for collaborative, real-time architectural design that is based on our 3D comparative navigation system and real-time simulation technology. We also evaluate the advantages and disadvantages of using this design environment to support collaborative architectural design.

title Improving spatial ability using a Web-based Virtual Environment (WbVE)
source Automation in Construction
summary Spatial ability is one of the cognitive means used in problem solving activities particularly when manipulating and processing visuo-spatial information. With the increasing use of network communication, conventional teaching and learning has shifted towards the development of network environments, online learning, real-time interaction and high quality multi-user collaboration. This paper presents our experiment using a Web-based Virtual Environment (WbVE) that has improved a group of pre-service teachers' spatial ability understanding for teaching Engineering Drawing for secondary school subjects. The experiment is carried out in Universiti Pendidikan Sultan Idris (UPSI) comprising of 98 pre-service teachers taking the Computer Aided-Design (CAD) course. Selected subjects were pre-tested at the beginning of the semester with spatial tests focusing on mental rotation and spatial visualization to provide the baseline measurement. A desktop WbVE, which was employed and tested in the CAD laboratories to improve their spatial ability for five weeks of instructional treatment, will be demonstrated. Post-testing of spatial tests revealed significantly the overall spatial ability improvements as measured by the test scores. This paper concludes with a discussion on the impact of WbVE spatial learning that will be used as a precedent in the development of the VE teaching and learning prototypes for secondary school in Malaysia.

summary Mindstage is a multi-user real-time 3D environment in which is embedded a lecture on film design by Christopher Hobbs. The spatial design follows the structure of the lecture, and is richly illustrated with stills and film clips. The environment, implemented in Virtools, proved to be a visually intriguing combination of architectural, filmic and virtual space, though it was found that co-presence induced some problems with the concept of time.

title Multidisciplinary Design in Virtual Worlds

summary Large design projects, such as those in the AEC domain, involve collaboration among a number of design disciplines, often in separate locations. With the increase in CAD usage in design offices, there has been an increase in the interest in collaboration using the electronic medium, both synchronously and asynchronously. The use of a single shared database representing a single model of a building has been widely put forward but this paper argues that this does not take into account the different representations required by each discipline. This paper puts forward an environment which provides real-time multi-user collaboration in a 3D virtual world for designers in different locations. Agent technology is used to manage the different views, creation and modifications of objects in the 3D virtual world and the necessary relationships with the database(s) belonging to each discipline.

summary Traditionally urban design is perceived, communicated and created using physical and digital media. However, these realms are handled as separate entities, which hinder collaboration, understanding and communication. Collaborative Augmented Reality (AR) systems can integrate these tasks into one media type and allow a different conversation with complex issues. Human Computer Interfaces and Tangible User Interfaces play key role in AR. They allow an engagement with both the real and virtual component of an urban design project. This paper describes an urban design studio that employs AR as medium of collaboration, the theoretical framework of sense of presence, the understanding and the quality of the resulting design.

title A Multi-dimensional Exploration of Urban Attributes by Data Mining
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. 333-350.
summary The paper which is proposed here will introduce an ongoing research project aiming to research data mining as a methodology of knowledge discovery in urban feature analysis. To address the increasing multi-dimensional and relational complexity of urban environments requires a multidisciplinary approach to urban analysis. This research is an attempt to establish a link between knowledge discovery methodologies and automated urban feature analysis. Therefore, in the scope of this research we apply data mining methodologies for urban analysis. Data mining is defined as to extract important patterns and trends from raw data (Witten and Frank, 2005). When applied to discover relationships between urban attributes, data mining can constitute a methodology for the analysis of multi-dimensional relational complexity of urban environments (Gil, Montenegro, Beirao and Duarte, 2009) The theoretical motivation of the research is derived by the lack of explanatory urban knowledge which is an issue since 1970’s in the area of urban research. This situation is mostly associated with deductive methods of analysis. The analysis of urban system from the perspective of few interrelated factors, without considering the multi-dimensionality of the system in a deductive fashion was not been explanatory enough. (Jacobs, 1961, Lefebvre, 1970 Harvey, 1973) To address the multi-dimensional and relational complexity of urban environments requires the consideration of diverse spatial, social, economic, cultural, morphological, environmental, political etc. features of urban entities. The main claim is that, in urban analysis, there is a need to advance from traditional one dimensional (Marshall, 2004) description and classification of urban forms (e.g. Land-use maps, Density maps) to the consideration of the simultaneous multi-dimensionality of urban systems. For this purpose, this research proposes a methodology consisting of the application of data mining as a knowledge discovery method into a GIS based conceptual urban database built out of official real data of Beyoglu. Generally, the proposed methodology is a framework for representing and analyzing urban entities represented as objects with properties (attributes). It concerns the formulation of an urban entity’s database based on both available and non-available (constructed from available data) data, and then data mining of spatial and non-spatial attributes of the urban entities. Location or position is the primary reference basis for the data that is describing urban entities. Urban entities are; building floors, buildings, building blocks, streets, geographically defined districts and neighborhoods etc. Urban attributes are district properties of locations (such as land-use, land value, slope, view and so forth) that change from one location to another. Every basic urban entity is unique in terms of its attributes. All the available qualitative and quantitative attributes that is relavant (in the mind of the analyst) and appropriate for encoding, can be coded inside the computer representation of the basic urban entity. Our methodology is applied by using the real and official, the most complex, complete and up-to-dataset of Beyoglu (a historical neighborhood of Istanbul) that is provided by the Istanbul Metropolitan Municipality (IBB). Basically, in our research, data mining in the context of urban data is introduced as a computer based, data-driven, context-specific approach for supporting analysis of urban systems without relying on any existing theories. Data mining in the context of urban data; • Can help in the design process by providing site-specific insight through deeper understanding of urban data. • Can produce results that can assist architects and urban planners at design, policy and strategy levels. • Can constitute a robust scientific base for rule definition in urban simulation applications such as urban growth prediction systems, land-use simulation models etc. In the paper, firstly we will present the framework of our research with an emphasis on its theoretical background. Afterwards we will introduce our methodology in detail and finally we will present some of important results of data mining analysis processed in Rapid Miner open-source software. Specifically, our research define a general framework for knowledge discovery in urban feature analysis and enable the usage of GIS and data mining as complementary applications in urban feature analysis.

title Modeling and visualizing the architectural project and their relationship with the nature and the environment using Biocad and CAACD: Computer Architectural Aided Climatic Design
source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 806-810
summary Architecture is built in artificial and natural environments, some are real others are virtual. Until now, CAAD, CAD, and 3D modeling and simulation software have not included the environment and are therefore limited to imprecise representations. This challenges the algorithmic complexity of the software that simulates elements of nature, air, natural and artificial light using techniques of radiosity and raytracing. Today, CAACD (Computer Architectural Aided Climate Design) software needs information like geographic location, atmospheric and climatic conditions of the place to use it in conceptual decisions during the design process and to be able to guarantee environmental comfort in the project. This situation has provided me, together with professors and postgraduate students in the discipline of landscape architecture, with the fundamental framework for my study, namely: The virtual construction of a region, including digital representation of the built environment and the tropical flora. This paper describes the basic methodology used in such a process. [Full paper in Spanish]

summary The paper is a follow-up to earlier work investigating the research hypothesis that Virtual Reality (VR) is nowadays a maturetechnology, suitable for communicating planning ideas. A work in progress involving the redesign of two squares within the urbanfabric of a deprived Athenian neighbourhood is presented. A VR model of existing and proposed layouts was constructed, focusingon accuracy of visualisation, ease of navigation, online spatialized commenting mechanism and ease of access. User groups weresupported with appropriate training—researchers had the opportunity to observe the reactions of people and deliver questionnairesthat help identify problem areas related to technophobia, disbelief, past knowledge, communication skills, understanding of thevisualisation system used, usability of the navigation system as well as the commenting mechanism. Gender and social exclusionare key issues in this particular multicultural neighbourhood. Collecting demographic data on all participants (age, sex, educationlevel, employment, marital status, etc.) during the commenting process enables a series of analyses testing the ways the system isused.

summary This study has two major concentrations: 1) exploring methods of creating a digital city model, and 2) applying the model to study urban spatial structure, an issue of particular interest and importance to urban planners. Based on existing studies that primarily address two-dimensional (2D) urban structure, this paper focuses on the three-dimensional (3D) structure relating to the 3D urban form. Given their greater clarity and possibilities for quantitative analysis, both 3D digital urban models and GIS spatial overlay analysis methods hold tremendous potential for analysing and predicting future urban form. In this project, the Xidan Business District in Beijing's Inner City was the area selected to implement the digital-city application. Under the hypothesis that the existing urban spatial structure is determined by the city's urban planning scheme and current urban marketing forces, it is found that actual urban development does not follow the planning restrictions on zoning and building height regulations. Some contradictions and conflicts, such as building location and height, appeared in the studied district. The specific reasons for the discrepancies need to be further studied.

summary This study integrates infrared distance measuring sensors and applies wrist rotations and hand movements to replace the space operations of conventional mouse and Data Glove. Through an array of infrared distance measuring devices, the position and direction of the hand in the space can be precisely detected, allowing designers to control 3D design objects intuitively in virtual spaces. The infrared distance measuring device adopted in this study has the effective test distance about 40 cm, with the precision range between 4 ~ 30cm, which is compatible with general hand movements. This device is expected to provide designers a more economical way to achieve intuitive operations in virtual spaces, as well as an intuitive way to explore virtual environments.

summary VR-based design environment have been traditionally not connected to companies’ design repositories and knowledge management systems. Till now these tools are mainly used for the initial exploration of innovative and original three-dimensional spaces and curves. Our approach encourages the use of VRbased design environments as design tools from where to reuse design solutions and to access design information, which are stored in internal repositories. This vision goes towards the development of a VR-based integrated design platform. Further, today’s knowledge management systems show evident limitations when dealing with multimedia files and 3D models. In order to overcome this limitation a framework for embedding in our VR-based design environment a Knowledge Management system for multimedia content has been developed and it is here described. Our solution implies the use of annotation languages such as the recent MPEG7 ISO/IEC (Multimedia Content Description Interface) standard for metadata, which is based on the XML language. Data types handled in our system are multimedia formats including text, audio, video, images, and 3D models. The main contribution of our research activity is in providing an innovative and original approach for supporting the design process, which takes advantage both of the visualization and design capabilities of virtual reality technology and of the reuse of design solutions directly in VE, through the retrieval of 3D models and multimedia data from various sources.

summary Design has been described as making inspire decisions with incomplete information. True, we may use prior knowledge, we may even think we understand the causalites involved, but what really matters is exploration: of new forms, of new materials, and speculation about the response to the resulting effects. Essentially, this exploration has its own dynamics, involving intuition and spontaneity, and without which there is no design. But of course we all know that this is not the whole story. Design is different to 'craft'; to directly 'making' or 'doing'. It necessarily has to be predictive in order to anticipate what the consequence of the 'making' or 'doing' will be. Therefore we inevitably have to counter balance our intuition with a well developed sense of premeditation. We have to be able to reason about future events, about the consequence of something that has not yet being made. There is always going to be an advantage if this reasoning can be achieved with a degree of precision. So how can we progress from intuition to precision? What abstractions can we use to represent, externalize and test the concepts involved? How can we augment the cognitive processes? How can we record the progression of ideas? And, how do we know when we have arrived? Design has a symbiotic relationship with geometry. There are many design issues that are independent of any specific configurations. We might call these “pre-geometric” issues. And having arrived at a particular configuration, there may be many material interpretations of the same geometry. We might call these “post-geometric” issues. But geometry is central to design, and without appropriate geometric understanding, the resulting design will be limited. Geometry has two distinct components, one is a formal descriptive system and the other is a process of subjective evaluation.

summary This paper describes the Pelourinho Project realized past July in Salvador, during the 1st International Conference on 3D Laser Scanning for Heritage Documentation. The Pelourinho located at the historic center of Salvador, is an impressive wide set of buildings listed by UNESCO as World Heritage. The text contains a quickly overview about the 3D laser scanning technology, shows how data are captured and what they stored and what they means. The 3D laser scanning model, another kind of 3D geometric model is called point cloud and represents an excellent way to store data of some particular constructions. Because its irregular shapes it is very arduous to survey and represent these constructions by any other method. The point cloud model is an excellent way to represent with integrity and accuracy these particular complex shapes like the colonial baroque churches in Brazil. [Full paper in Portuguese]
