title	Dynamic Designs of 3D Virtual Worlds Using Generative Design Agents
source	Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 239-248
summary	3D virtual worlds are networked environments designed using the metaphor of architecture. Recent developments in 3D virtual worlds focus on interactivity, flexibility and adaptability. Rather than creating virtual environments in which the objects have intelligent behaviours, our research takes a different approach to develop an agent model that is associated with an individual person in the 3D virtual world as a personal design agent. This paper presents a Generative Design Agent (GDA), a kind of rational agent capable of representing a person in a virtual world and designing, implementing and demolishing 3D virtual places based on the occupants' current needs in the virtual world. The core of a GDA's design component is a generative design grammar that is able to capture a style of 3D virtual worlds. 3D virtual worlds designed using the GDA model is another kind of architecture for the "moment".

title	Multi-user virtual worlds: 3D interactive visualization in synthetic environments for design workshops
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 344-349
summary	The goal of this research is to describe a methodology of architectural design by using digital technology with three-dimensional interactive simulation in multi-user virtual worlds. In addition, this study will focus on the application of this method in the workshops at the School of Architecture in the University of Zulia. With this proposal, it is possible to integrate many users, in real time, from different locations on the same virtual world in Internet. In the same way, each visitor is able to interact and modify the virtual world using virtual menus while sharing ideas or modifications regarding the design of the project. This strategy allows modeling, visualizing, developing and evaluating the designed projects during the conceptual and parametric phase in the process of design. This application is a powerful tool to develop creativity and skills of spatial perception among the students. [Full paper in Spanish]

title	Architectural Cinematographer: An Initial Approach to Experiential Design in Virtual Worlds
source	Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 135-144
summary	This paper presents a paradigm for the generation of camera placements for architectural virtual environments as a method of enhancing the user's experience and as a way of facilitating the understanding of architectural designs. This paper reports on an initial prototype of a real-time cinematic control camera engine which enables the creation of architectural walkthroughs with a narrative structure. Currently, there is neither software nor a structured approach which facilitates this in architectural visualisations. The paper discusses the potential of our approach; analyses the technical and application domain challenges; examines its current limitations using well known architectural design concepts such as rhythm.

title	Urbamedia: the design of an integrated system of urban-building visualization and communication
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 603-608
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.

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.

summary	The central feature of the project is the development of a computer and its interfaces to simulate urban space and, in the context of an intermedia city tour, to allow citizens to creatively influence their urban space by manipulating media structures at chosen points throughout the city. A master plan is set up to re-cultivate public spaces and points of architectural focus. The city reacts interactively to the commands. A dialog is created between user and public space. The tour route is an open structure which can be expanded at any time. Via interfaces the user activates a reaction in the real city by making changes to the virtual model. This results in a dynamic space, a communication based on the results of this transformation. The user interface allows an information transfer between real people and virtual space. Virtual reality then reacts to the input by transferring that information back to reality. The direct influence on the architecture is effected by a media-transformer. It projects an additional perception level on to reality while monitoring the data via various analysis interfaces.

title	Teaching Programming for and with Microcontroller-Enhanced Physical Models
source	International Journal of Architectural Computing vol. 3 - no. 1, 57-74
summary	As processes of use, interaction and transformation take center stage in various fields of design, electronic sensors, controllers, displays and actuators can significantly enhance the value of physical models. These technologies allow the development of novel computer interfaces for new kinds of interaction with virtual models, and in the future they can be expected to play an important role in the development of new types of active building components and materials for automated construction and dynamic runtime adaptations of inhabitable environments. However, embedding programmed logic into physical objects involves skills outside the traditional domains of expertise of designers and model makers and confronts them with a steep learning curve. The wide variety of alternative technologies and development tools available in this area has a particularly disorienting effect on novices. However, some early experiences suggest that mastery of this learning curve is easily within reach, given some basic introduction, guidance and support. To assist design students in acquiring a basic level of programming knowledge, better educational programming tools are still required. It is the intent of this paper to provide designers and educators with a starting point for explorations into this area as well as to report on the development of an educational approach to electronics programming called haptic programming.

title	GENERATIVE INTERFACES AND SCENARIOS - INTERACTION IN INTELLIGENT ARCHITECTURE
doi	https://doi.org/10.52842/conf.ecaade.2005.107
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 107-113
summary	New media and modern building automation have a strong impact on contemporary architecture. So far one could regard built architecture as static. These new technologies introduce a dynamic impulse to architecture. The objective of our research and teaching work is to demonstrate the impact of innovative systems on architecture in daily usage while providing building automation, multimedia integration and facility management services in intelligent networked buildings. These technologies, as described in this paper are integrated in our second year course for students of Architecture. By designing an interactive graphical interface for the lab they were asked to create a spatial scenario as a self running Flash animation. Thus real space is merged with virtual reality.

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	Complexity as a Creative Force in Design Variegation, Heterogeneity, Diversity
doi	https://doi.org/10.52842/conf.acadia.2006.510
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 510-517
summary	This paper describes an experimental project that attempts to use complexity as a creative and vital force within the design process. The project seeks to release architecture from its conventional role as a static urban backdrop and to transform it into a vital, dynamic, and active participant within cities. The project, entitled “Energy Farm”, was instigated by the 2005 International Open Design Competition for a “Performing Arts Island” located within the Han River in Seoul, Korea. Through the exploration of the site and program elements as an interacting matrix of fields, forces, and flows (energy, program, water flow, infrastructure, etc.), our proposal emerged as a variegated landscape marked by its capacities to produce its own energy, interweave heterogeneous threads of structure and program, and instigate a diverse set of scenarios in which physical and virtual realms coalesce. Architecture, in its unique capacity to bridge these realms, can release the rich computation potential of complexity into the physical realm. Within this scenario, architecture becomes a creative and vital agent for productive change with profound social, political, and ecological implications.

summary	We are engaged in the process of exploiting gestural signs and pedestrian postures for the purpose of utilizing additional possibilities through the creation of a new Wearable Electronic Garment, as medium for inscription. Animated, cyber-performers move, deform, and re-arrange themselves, augmenting the dimensions of expressiveness/meaning during performance. The cognitive approach produced by thinking in/out of these bodies will similarly trigger changes in consciousness, affecting content and virtual story telling. Together we explore the interaction of text/gestures as movement—as in dance, human day- to-day postures, and our capacity to embody and generate meaning. Cyber dancers use gestures in order to cybernetically inscribe them. The composed gestures become the source of intention that relates to itself; its communicating environment becomes a visualization of the self-reflexivity of both the dance and consciousness. The dance is between worlds of humans, cyber-humans, and the source language as transforms into the domain of visible thought.

title	Townscaping: Development of Dynamic Virtual City Augmented 3D Sketch Design Tools
source	Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 105-114
summary	The paper presents the development of an experimental Web-based design environment called Townscaping to be used at the conceptual stage of architectural and urban design. Inspired by Gordon Cullen's seminal work on Townscape (1960's-1970's), the idea of Townscaping is to explore how 3D digital sketch design tools could be developed to operate in connection with a dynamic virtual city system under a user's direct control. A prototype of Townscaping has been designed and implemented on the basis of an existing dynamic virtual city system. In Townscaping, a set of tools is provided for users to create and edit 3D graphic elements to be positioned directly onto the user-specified virtual city models. One of the key features of Townscaping is to enable sketching while navigation: designers can perform sketch design and gain immediate visual feedback while navigating the 3D virtual city models to any viewpoint at any moment. The current study suggests that it is feasible for virtual city models to serve as interactive urban contexts for 3D sketch design. Townscaping is considered primarily a research platform with which we are interested in investigating if designers' engaging in 3D space conceptions may be enhanced through interacting and sketching with virtual townscapes.

title	Simulation of architectural lighting in a virtual environment - A case study on real and fake High Dynamic Range Images (HDRI)
doi	https://doi.org/10.52842/conf.ecaade.2006.566
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 566-572
summary	The early findings of this research were presented in eCAADe 2005 International Conference, Lisbon primarily to highlight the concept of High Dynamic Range Images (HDRI) when representing architectural spaces in the form of still images. An experiment had been carried out to compare the results between HDRI rendering and ‘conventional’ lighting simulation algorithms namely ray tracing and radiosity. The results were based on static and using the same exposure factors, when capturing HDRI. This project, funded by Intensification Research Priority Area (IRPA) grant continues to present and report HDRI results in a simulation environment. In this paper, we first briefly explain on the concept of real and fake HDRI. Then a comparison experiment is conducted to compare these two methods and discuss the impact and effectiveness of the illumination computation in architectural simulation environment. In order to carry out the experiment, a few models of the architectural scenes were developed. These models were then textured with real photos and manipulated with ‘shaders’, and further rendered using fake and real HDRI techniques. As for the fake HDRI, two methods were developed. The first was using an image as the ambient map and different exposures were created by increasing the value of Hue, V of HSV and saturation. The second involved a series of digital photos with the selection of the brightest and darkest area using Adobe Photoshop to establish the scale of luminosity. A few camera movements were triggered and position for ‘real-time’ rendering simulation. The result of the experiment has shown a significant improvement on the rendering time and quality of the rendering. Finally this paper suggests the selection criteria for choosing real and fake HDRI, and how each technique can be best utilized for architectural representations in a simulation environment.

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	This paper describes the latest results of an ongoing research project that aims at using the power of self-organization for the design and optimisation of irregular spatial structures in real-world applications. An example is presented, which uses a growing swarm to define the configuration of randomly positioned columns in a large concrete structure. This agent based simulation, developed in cooperation with the building's architects and engineers, was successfully used in the final design stage of a project in the Netherlands to resolve the conflicting structural and functional requirements arising from the initial design.

title	Real-time Simulations Using Learning Algorithms for Immersive Data Visualization in Buildings
source	International Journal of Architectural Computing vol. 3 - no. 3, 265-280
summary	Computational Fluid Dynamic (CFD) simulations are used to predict indoor thermal environments and assess their response to specific internal/external conditions. Although computing power has increased exponentially in the past decade, CFD simulations are still time-consuming and their prediction results cannot be used for real-time immersive visualization in buildings. A method that can bypass the timeconsuming simulations and generate "acceptable" results will allow such visualization to be constructed.This paper discusses a project that utilizes a supervised Artificial Neural Network (ANN) as a learning algorithm to predict post-processed CFD data to ensure rapid data visualization. To develop a generic learning model for a wide range of spatial configurations, this paper presents a pilot project that utilizes an unsupervised Reinforcement Learning (RL) algorithm. The ANN technique was integrated with an interactive, immersive Augmented Reality (AR) system to interact with and visualize CFD results in buildings. ANN was also evaluated against a linear regression model. Both models were tested and validated with datasets to determine their degree of accuracy. Initial tests, conducted to evaluate the user's experience of the system, indicated satisfactory results.

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.
