summary SPOT is a 3D environment for direct sunlight visualization. Implemented in Java 3D, SPOT features two distinct and complementary components: Time Projection and Navigable Animation for virtual interaction. SPOT supports multi-dimensional data visualization including sun angle variations with diurnal and annual cycles in threedimensional space. In SPOT users can sketch on any surface in the 3D environment to indicate the area for simulation. SPOT then generates a spatial distribution representation of the illuminance level on a selected surface over time, rendered with colors of varied gradients. SPOT also enables designers to visualize the temporal information of light distribution over time for a given point. For each point clicked on the 3D model, SPOT generates a calendar diagram where the X and Y axis represent the months of the year and the time of the day. The color of each cell of the calendar is the result of the calculation of the light amount reaching the selected point.

title Possibilities of applying the E-government management concept in Serbian cities
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary Recent urban transformations worldwide consequentially lead to the numerous environmental problems that have to be solved bycomplex structure of social interest groups which have to be included in that process. This demands initiated requisitioning andmodification of concepts and methodologies of planning and managing urban development. At this moment there are differentmodels used in world wide practice, but main bases of new methods and techniques are the same. Leaving the idea of possibility ofconstituting the universal urban planning model lead to very productive results in developing the disciplinary methodologies. Processof transformation of traditional comprehensive urban planning model to integrated procedural pluralistic model (based on sustainabledevelopment principles) is something that can be underlined as a main characteristic of disciplinary development. The questions ofdecision making mechanisms and plans implementation are put in axes of conceptual and methodological considerations. Urbanplanning loses the classic form of making the multi level comprehensive urban plans with exact spatial and time horizon. It means, ingeneral that planning and managing of urban development is aiming to be realistic, decentralized, strategic and problem oriented,arbitrary, not instructive, but understood as a efficient and effective process.Operational support to the this kind of approach are Decision Support IT tools, such as GIS - Geographical Information Systems orES -Expert Systems. Usability of IT tools is based on their capability to perform fast and complicated processing of spatial data andon their flexibility towards specific real problems which are to be solved. In order to use maximum of capabilities of these tools inpractice problem solving it is necessary to adjust their structure and usage to the: - actual conditions of socioeconomic of the contextin which urban development planning and management is performed, - practical demands that managing of urban development has tofore fill, - all participants in urban management process, - institutional mechanisms and procedures.

title Serial Vision Revisited: Prospects of Virtual City Supported Urban Analysis and Design
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. 259-270
summary Following our previous research on developing a dynamic virtual city system (Sheffield Urban Contextual Databank, SUCoD), the paper reports on a study of applying the virtual city resources to an undergraduate urban design course. The study focuses on how the multi-dimensional and multiple types of urban contextual data can be used by student designers directly for urban visual analysis and design development. A link is made with the Serial Vision in Townscape first proposed by Gordon Cullen, which sets out an experiential approach to how a living city environment should be read and understood. Drawing on the project works produced by the students, some patterns of generating urban narratives and 3D spatial designs were observed. Although the current experiment with SUCoD is limited in terms of data scope and modelling capabilities, it reveals a future direction to follow that can turn conventional virtual cities into Web-based online services capable of supporting urban design analyses and syntheses directly.

title A Procedural Model for Integrating Physical and Cyberspaces in Architecture
source Doctoral dissertation, University of Plymouth, Plymouth, U.K
summary This dissertation articulates opportunities offered by architectural computation, in particular the digital simulation of space known as virtual reality (VR) and its networked, social variant cyberspace. Research suggests that environments that hybridize technologies call for a conception of space as information, i.e. space is both a product of and tool for cognition. The thesis proposes a model whereby architecture can employ this concept of space in creating hybrids that integrate physical and cyberspaces.The dissertation presents important developments in architectural computation that disclose concepts and values that contrast with orthodox practice. Virtual reality and cyberspace, the foci of this inquiry, are seen to embody the more problematic aspects of these developments. They also raise a question of redundancy: If a simulation is good enough, do we still need to build? This question, raised early in the 1990's, is explored through a thought experiment - the Library Paradox - which is assessed and critiqued for its idealistic premises. Still, as technology matures and simulations become more realistic the challenge posed by VR/cyberspace to architecture only becomes more pressing. If the case for virtual idealism seems only to be strengthened by technological and cultural trends, it would seem that a virtual architecture should have been well established in the decade since its introduction.Yet a history of the virtual idealist argument discloses the many difficulties faced by virtual architects. These include differences between idealist and professional practitioners, the failure of technology to achieve its proponents' claims, and confusion over the meaning of virtual architecture among both architects and clients. However, the dissertation also cites the success of virtual architecture in other fields - Human Computer Interface design, digital games, and Computer Supported Collaborative Work - and notes that their adoption of space derives from practice within each discipline. It then proposes that the matter of VR/cyberspace be addressed from within the practice of architecture, a strategy meant to balance the theoretical/academic inclination of previous efforts in this field.The dissertation pursues an assessment that reveals latent, accepted virtualities in design methodologies, instrumentation, and the notations of architectural practices. Of special importance is a spatial database that now pervades the design and construction processes. The unity of this database, effectively a project's cyberspace, and its material counterpart is the subject of the remainder of the dissertation. Such compositions of physical and cyberspaces are herein called cybrids. The dissertation examines current technologies that cybridize architecture and information technology, and proposes their integration within cybrid wholes. The concept of cybrids is articulated in seven principles that are applied in a case study for the design for the Planetary Collegium. The project is presented and critiqued on the basis of these seven principles. The dissertation concludes with a discussion of possible effects of cybrids upon architecture and contemporary culture.

title The Dynamics of Physical Ambiences
source Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 174-181
doi https://doi.org/10.52842/conf.acadia.2007.174
summary This research proposes to support the reading of physical ambiences by the development of a representational technique which compiles, in a numerical interface, two types of data: sensory and filmic. These data are recorded through the use of a portable array equipped with sensors (Potvin 1997, 2002, 2004) as well as the acquisition of Video information of the moving environment. The compilation of information is carried out through a multi-media approach, by means of a program converting the environmental data into dynamic diagrams, as well as the creation of an interactive interface allowing a possible diffusion on the Web. This technique, named APMAP/Video, makes it possible to read out simultaneously spatial and environmental diversity. It is demonstrated through surveys taken at various seasons and time of the day at the new Caisse de dépôt et de placement headquarters in Montreal which is also the corpus for a SSHRC (Social Sciences and Humanities Research Council) research grant on Environmental Adaptability in Architecture (Potvin et al. 2003-2007). This case study shows that the technique can prove of great relevance for POEs (Post Occupancy Evaluation) as well as for assistance in a new design project.

summary In order to design architecture projects, 1st grade architecture students have to understand the space and how to figure it out. To be succeeded in the design process it is necessary to develop their spatial abstraction capability. Each architectural representation tool can contribute for this development. This work shows the pedagogical experience applied to students of the first grade of architecture course at UNICENP, in Curitiba, Brazil, approaching the strategies of different subjects to increase the development of spatial skills using different architecture design tools.

title Changing the Metaphor: Cyberspace as a Place
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. 19-28
summary Cyberspace is quickly becoming an alternative ‘place’ for everyday economic, cultural, and other human activities. It ought, therefore, to be designed according to the principles, theories, experiences, and practices that have been guiding physical placemaking for thousands of years, rather than the woefully inadequate metaphor of the printed page. 3D Cyber-places must embrace the essential characteristics that make a ‘place’ in physical space, while at the same time take advantage of the opportunities offered by Cyberspace. By looking at physical architecture as a case study and metaphor for organizing space into meaningful places, this paper discusses the possibility of organizing Cyberspace into spatial settings that, like physical places, afford social interaction and embody cultural values.

doi https://doi.org/10.52842/conf.caadria.2003.541
summary This research intends to propose a scheme for analyzing Chinese Garden Design by incorporating spatial theory, data mining, concept of object, and network-like data structure. Design elements of Chinese garden are placed in a network according to the existing gardens according to spatial theory. Collected networks are then divided into pair of elements connected by their relationship and stored in a database. Later, data mining is applied to attain patterns from the node-and-relationship pairs. Meanwhile, the elements of the same level can be classified and data grouping can be done by the implementation itself. Thru this research, we can gain insight upon the spatial information and relationship between elements of Chinese garden designs. The result is a set of more concise and structural descriptions, which reveals the rhythm behind the Chinese garden design and can be a great pedagogical aid.

title Drama and Context in Real-Time Virtual Environments: Use of Pre-Scripted Events as a Part of an Interactive Spatial Mediation Framework
source TIDSE ’03 Technologies for Interactive Digital Storytelling and Entertainment, S.Goebel, N.Braun, U.Spierling, J.Dechau, H.Diener (eds.) Darmstadt, Germany, 24-26 March 2003. Fraunhofer IRB Verlag, Stuttgart, ISBN 3-8167-6276-X, pp. 296-310
summary We suggest that the dramatically engaging mediation of an experience of place should be built in as a fundamental capability of a compelling and meaningful virtual environment (VE). Our main objective is to develop flexible interactive techniques that supply VE’s with a coherent context and make the resulting ‘virtual place’ available to the user in a dramatically engaging way. To support the concept of narrative expressive space, we propose a three-layer multi-purpose spatial mediation framework that utilizes an interactive narrative structure to coordinate stylized dramatic camera work, lighting, effects and sound. We then describe the use of pre-scripted events as a layer in this framework and explain the inherent benefits and problems, using a single-user prototype environment as illustration. The work offers guidelines for the design of VE’s to all fields that combine narrativity and spatiality, such as interactive entertainment, education and architecture.

summary The incorporation of virtual technologies to the learning process in architectural design is still incipient, using graphic software mainly as a rendering tool late in the curriculum. This paper presents an experience carried out with first year studio students, at the School of Architecture of the University of Chile, in which the intention is to incorporate virtual learning as part of the process spatial modification thinking. Through the use of Form Z, friendly software to learn for beginners, applied for simple extrusions, geometric transformations as translation, rotation or scaling, and the transformation of geometries and proportions through the handling of topological levels of polygonal objects. Through increasingly complex exercises we developed an effective complement of a traditional design methodology.

title Spatial Understanding in Immersive Virtual Environments
source International Journal of Architectural Computing vol. 1 - no. 4
summary In this study, we examined the perception and understanding of spatial volumes within immersive and non-immersive virtual environments by comparison with representation using conventional media. We examined the relative effectiveness of these conditions in enabling the translation to a tangible representation, through a series of design experiments. Students experienced, assessed, and analysed spatial relationships of volumes and spaces and subsequently constructed real models of these spaces. The goal of our study is to identify how designers perceive space in Virtual Environments (VEs). We explore issues of quality, accuracy and understanding of reconstructing architectural space and forms. By comparison of the same spatial performance task undertaken within a Head Mounted Display, screen-based and real 2D environment, we are able to draw some conclusions about spatial understanding in immersive VE activity.

title Augmented Reality Aided Design
source International Journal of Architectural Computing vol. 1 - no. 4
summary Ten years after Nielsen wrote about the "next generation interface" [1] we are still largely confined to WIMP [2] interfaces in design computing. A big question that lies ahead is 'Does the integration of computing technology through Augmented Reality help the formal design investigation process?' There are several suggestions that the conventional desktop metaphors are counter-intuitive for understanding spatial relationships [1, 3, 4]. Main concern is the mismatch in mapping of presentation and interface. Looking at other research areas, one can see that the application of Augmented Environments (AE) can enhance the speed of decision making [5] or creates better understanding of complex spatial arrangements [6] due to the fact that information is displayed where it occurs. Obviously, the representation and interaction is crucial for perceptive performance in design sketching as it is in AEs. This article will discuss a software prototype called sketchand+ and the implications of Augmented Reality for digital design.

title Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call “business views”. We propose a 4 steps-method to compose business views. The first step identifies the users’ business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user’s interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

summary Illumination phenomena simulation is important for architectural project design and communication: simulation tools must assist efficiently the designer; results have to be reliable and realistic for the decision-makers. Indeed, it is very difficult, for a nonspecialist to imagine the result of an illumination from the light designer plans. Experience shows that the success of a photo-realistic simulation relies essentially on the choice of the light source characteristics and their correct positioning in the scene. This paper first presents the specificities of illumination projects (very large geometrical data bases enlightened by a large amount of light sources) and the difficulties of their set-up. Light arrangement requires tricky compositions, judicious choices and accurate studies. Currently there is no specific modeller for the handling of light sources as they are considered in radiosity software. Then we present the interactive tool we have developed, named ModLum, in order to set up light sources in a 3D architectural model in order to save time during the design step and simplify the source handling. ModLum specifications and principles are presented. Finally, an application is presented: the illumination project of two cloisters in Quito (Ecuador, South America).

summary Sketching is a major means of exploiting the first conceptual developments in architectural design. If we want to support the architect in the ideas-developing phase of design, then we need to understand the conventions of depiction and encoding in drawings. The theory of graphic units provides an extended list of such conventions that are widely used. We propose that a multi-agent system for recognition of graphic units in drawings is fruitful: agents can specialize in graphic units, a multi-agent system can deal with ambiguity through negotiation and conflict resolution, and multi-agent systems function in dynamically changing environments. We first make a multi-agent system that can do something simpler: playing Mah Jong solitary. The Mah Jong solitary system shares the following important features with a multi-agent system that can recognize graphic units: (1) specialized agents for moves; (2) negotiation between agents to establish the best move; (3) dynamically changing environment; and (4) search activity in more advanced strategies. The paper presents the theoretical basis of graphic units and multi-agents systems. The multi-agent framework and its implementation is presented. Various levels of game play are distinguished, and these are correlated to the multi-agent system. The paper shows how the findings form the basis for graphic unit recognition.

summary Since 2003, we have been developing a pedagogic proposal and didactic material for teaching Light and Optics to kindergarden children that enhances the construction of the first scientific thinking schemes. The design (industrial and graphic) applied to this project has generated an educational product composed of 44 objects. These materials allow teaching concepts such as: combination of colors, light indispensable to see, formation of shadows and images are not objects. These have been developed as inciters of curiosity, capable to awake the innate restlessness of children, achieving to stimulate their creativity. The purpose is to explore knowledge and construct their own ideas; enrich their experiences and inquire a reality that was drawn grey and tedious, generating a process of manipulation-action and then representation-conceptualization. This product has been successfully used as a pilot test in a kindergarden, reflecting significant gains in students’ science learning. [Full paper in Spanish]

title Information Spaces for Mobile City Access
source International Journal of Architectural Computing vol. 1 - no. 1
summary This paper describes two complementary European research projects that share common interests and goals.The work described is intended to facilitate city analysis and support decision-making. The first project focuses on the distribution, access and ease of use of city data. The system allows access to historical data concerning key buildings in Liverpool, England, via a suite of web-based tools and a palmtop device. The second project looks at extending the functionality of traditional computer aided design (CAD) software to enable geometric and semantic data to be combined within a single environment. The system allows those involved in city planning to better understand the past and present development pattern of an area so that their decisions on future proposals are better informed.The paper concludes by describing a system that integrates particular aspects of the two projects, and the potential that this integration can bring.This new work provides mobile access to historical city development data, current city information and tools to support urban project development.

In order to take even more advantage of VRML, we developed an application of virtual menus within VRML using Java Script as a first step to the creation of a Synthetic Environment Laboratory for architectural design. This paper briefly presents the criteria used to define the menus, the utilization of Visual Basic programming to allow the addition of said virtual menus to any file with extension *. wrl, specific examples of applicability of the menus developed, and how they were inserted in a methodological model of architectural design.

title Developing a Building Design Compiler that Frequently evaluates Building Design Performance within the Design Process

summary This paper demonstrates an experience in the development of a design performance evaluation system that can frequently evaluate building design performance within the design process in a real-time manner. The evaluation system, that we call "design compiler," is composed of several modules such as a front-end component-based CAD engine, a knowledge base, and a set of design agents. The notion of the design compiler is quite similar to a compiler for computer programming such as a C compiler. While a computer programmer compiles a set of programming codes to check compiling errors during the implementation of a software system, an architectural designer can 'compile' his/her intermediate design product to evaluate design errors during the design process. The compilation can be done immediately at any level or any time during the design process in a real-time manner. We expect that this compiling process will dramatically increase design feedbacks, and thus result in a better design product. Further research issues that have been identified at the end of the research include increasing the modeling capability, extending to multi-story building representation, developing various design agents, exploring better ways to request and manage design knowledge, and supporting design collaboration.

title IMPROVING NEURAL NETWORK MODELS OF PHYSICAL SYSTEMS THROUGH DIMENSIONAL ANALYSIS
source Journal of Applied Soft Computing 2(4): 283-296.
summary The paper presents a technique for generating concise neural network models of physical systems. The neural network models are generated through a two-stage process. The first stage uses information embedded in the dimensions or units in which the data is represented. Dimensional analysis techniques are used initially to make this information explicit, and a limited search in the neural network architecture space is then conducted to determine dimensionless representations of variables/parameters that perform well for a given model complexity. The second stage uses information available in the numerical values of the data to search for high-level dimensionless variables/parameters, generated from simple combinations of dimensionless quantities generated in the first stage and which result in concise neural network models with improved performance characteristics. The search for these high-level dimensionless variables/parameters is conducted in an enhanced representation space using functional link networks with flat or near flat architectures. The use and effectiveness of the technique is demonstrated for three applications. The first is the design and analysis of reinforced concrete beams, which is representative of the class of problems associated with the design and analysis of composites. The second is the classical elastica problem, for predicting non-linear post-buckled behaviour of columns and the third, the analysis of a bent bar under a specified combination of loads.
