title	Navigation In 3D Information Landscape-A 3D Museum for Civic Buildings
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 641-650

summary	Navigation is about information that requires visual feedback and spatial orientation in both information representation and userinteraction. Among those, spatial orientation is the primary research question for navigating in 3D information landscape. By inspired by Ware's three control loops, 'spatial metaphors' and 'visual components" are proposed as the fundamental concepts of a navigation framework called 'i-Room'. i-Room is comprised of four constituents-handles, i-Bag, i-Map and Focus/scale. An information landscape based on a repository of diverse digital media of 11 significant civic buildings in Taiwan is designed for testing this navigation framework. An implementation of i-Room based on Muse of navigation realization and their interaction behaviors with spatial metaphors/visual components is also reported in this paper.

title	An Agent Approach to Supporting Collaborative Design in 3D Virtual Worlds
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 47-52

summary	3D Virtual worlds facilitate a level of communication and collaboration not readily available in conventional CAD systems. The integration of virtual worlds and CAD systems using a common data model can make a significant impact on synchronous collaboration and real time multi-user multi-disciplinary modification of building data. By using agents, the integration of 3D virtual worlds and CAD systems can go beyond that of passive data transfer. With sensors and effectors, each agent can interact with its environment by responding to changes in the CAD system or 3D virtual world, which can take the form of an update to the geometry, or as a recommendation to change non geometric information or to propagate changes to other parts of the design. The reasoning process for each agent can vary from a reflexive behaviour in which the agent responds directly to the sensor data to a reflective behaviour in which the agents reasons about its goals and alternatives before making a change to the environment. We demonstrate this approach using ArchiCAD and Active Worlds as the CAD system and the virtual world platform. An EDM database is used as the central repository for storing the representation of the relevant data model. A multi-agent system is developed to connect the virtual world to this database to allow active data sharing. This agent approach can be extended to the integration of other applications and data models.

summary	A Multidimensional Presentation Environment (MPE) is defined here as a digital environment containing spatially located data that can be navigated by a presenter. Given an array of data types and the potential infinity of the associated datascapes, there is an opportunity to develop systems that assist the presenter in the navigation and analysis of complex information scenarios. This research reports on the utilisation of intelligentagent based software for a better understanding of spatial information representation within the MPE. This is achieved by utilising intelligent agent software to aid the presenter in the searching, retrieving, and articulation of datasets, and the application of such technologies in the generation of time based 3D graphical and audio presentations.

title	An Object Server System for 3D Digital Design Collaboration

summary	Moving through and between computer generated 3D objects we experience a 'virtual world'. Virtual Worlds have created a dream-like landscape. They also have facilitated a paradigm shift for architects working with CAD tools where they now desire to “design three-dimensional spaces in an immersed way” (Strehlke and Engeli 2001). Architects are already working in computer-moderated collaborative networked organisations. A 3D Virtual World offers a different kind of collaboration. To understand how architects might design in an 'immersed way', three experiments are described. The experiments attempt to investigate how participants experience the 3D spaces within which they collaborated. In particular, the last experiment makes use of 'shared objects' in the scene. The software chosen to create these Virtual Worlds was VRML and JAVA due to their flexibility and rapid prototyping. Where VRML differs from most CAD languages is in its openness. This paper describes an object sharing client-server architecture based on a simple multi-user system providing navigation in CosmoPlayer 2.11 ported through Netscape. The Object Server System allows multiple clients, as avatars, and objects to be manipulated in a 3D Virtual World. The system updates the transforms of the objects explicitly allowing their transform values to be shared across multiple browser sessions.

doi	https://doi.org/10.52842/conf.ecaade.2003.369
summary	The research project in progress in the School of Architecture at the Izmir Institute of Technology includes documentation and reconstruction (by 3D modeling in electronic media) of damaged and lost early modern buildings in the Izmir region. The research aims to analyze the differences between Izmir modern buildings and Universal Modern Style, and preserve information on architectural heritage for future generations. The project is at the phase of developing an interactive web-based historical database (HizmO) that includes data (information, images, technical drawings, VRML models) and visualization of the findings. This database aims to be a pioneer in Mediterranean Region for exhibition of relations between traditional architecture (especially Mediterranean locality) and modernism, and organization of a network and off-campus learning activity for Mediterranean architecture that serve as a guide for students, researchers and architects. This paper aims at introducing this research and discussing the application of the database “HizmO,” its aims and potential effects on education in architectural history.

summary	Digital visualization addresses representational challenges from within and without architecture. ‘Disciplinary’ digital visualization is used to explore, understand and communicate architectural information associated with the production of buildings. 3D modeling, rendering, animation and VR as well as the power of digital media to permit the seamless integration of various data types are unleashing completely new ways to display architecture. As digital power continues to increase and get cheaper, portability and wi-fi networks take root, and visualization work becomes even more main stream, we can expect growing changes in the way the design process is conducted, buildings are presented and documented, and the public and 3rd party’s demands from professional services. This demands a more conscious research/pedagogies aimed at developing new representation conventions.

summary	The purpose of this work is to develop needed interaction techniques for understanding the context of a digital city. In this paper, we present a framework in terms of three perspectives: information representation, physical interactions and media space design. We implement tangible media for physical interactions, allowing users to explore a digital city with respect to different positions in time-space in an interactive and intuitive manner. The time-space representation is mapped to physical media space. Our work is demonstrated in a digital 3D museum project for Tainan city in Taiwan.

title	Modeling of Activities: an approach to the virtual representation of human behaviors in architectural spaces tested in emergency units
source	International Journal of Architectural Computing vol. 1 - no. 3
summary	Despite the increasing interest in the functionality and humanization of architecture, there are few studies covering the occupation of buildings and methods to represent activities in spaces. This article explores new software for simulating and virtual modeling in order to facilitate the analysis and visualization of events in buildings. Of particular importance is programming the behavior of 3D-characters according to the probabilistic evolution of activities, and producing animations and interactive models. This approach was tested in a study of three emergency units of hospitals in Chile. Although a full integration of software was not possible, the process developed (in particular the subjective tours) demonstrated that the technique can provide new information about the functioning and spatiality of the units. In addition, it suggested operative and architectural improvements supporting the management and design of facilities.

title	Generation and visualization of 3D-city and facility models using CyberCity Modeler (CC-Modeler)
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The efficient generation of data for 3-D city models and their handling in Spatial Information Systems has become feasible. The derivation of this data from aerial and terrestrial images with semi-automated techniques constitutes the most powerful tool currently available to fulfill this task. Semi-automated object extraction has become a viable concept for the generation of 3-D city models. CyberCity-Modeler (CC-Modeler) has been developed with the aim of creating not only buildings, but also other objects pertaining to a city model efficiently and with a high degree of flexibility concerning the level of detail. In its commercial implementation, CCModeler has been confronted with a number of user requirements which needed to be observed. This led to some extensions in functionality, which are addressed in this paper: Geometrical regularization of buildings, editing functions for topology adjustment, integration of facades and other vertical walls and modeling of overhanging roofs. These extensions of the original concept make CyberCity-Modeler an even more powerful tool for 3-D city modeling.

summary	The proposed VLM system intends to facilitate the visual sustainability of urban natural landscape in China. In this system, GIS not only provides technologies for the inventory of landscape characteristics and the visual landscape evaluation, but also contributes to public or professional communication supporting through modeling and visualization. Therefore, GIS holistically acts as a fundamental support in this prototype system. Combining with psychophysical landscape evaluation (LE), photogrammetry and other digital 3D visualization, GIS provides quantitative data, scientific visualization and visual simulation for planning decision making.

summary	By exploring interactions between users and information, this paper intends to propose a co-existence framework for companying physical space with virtual space. Based on this framework, we implement an information structure for users to interact with information space interactively, which includes information nodes, hyperlinks and interplays through i-Room system (Chang and Lai, 2003). Furthermore, the information structure of representation is also tested and reevaluated in representing ten historical significant civic buildings in Taiwan.

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London.

summary	The current debate of architecture education in UK Schools of Architecture is reviewed with special emphasis on environmental ingredients of the traditional and progressive curriculum. Environmental approach to design has far more benefits than just informing students of the basics of the ecological and urban settings. Traditionally, UK Schools of Architecture address these issues via required courses (RIBA, 2003) However, environmental forces, wide array of educational innovations and a number of conditions and performance criteria that are set by Royal Institute of British Architects RIBA, for architectural education curriculum are essential drivers that necessitated transforming architectural pedagogy. As a result, new themes are being woven across existing courses, and more attention is being accorded to pedagogical methods of delivery using Information and Communication Technology ICT.

summary	"This paper investigates the role of gaming engines in the architectural design process through the introduction of features such as immersion, interaction and collaboration. While traditional 3D modelling and visualization systems such as 3D Studio MAX and form?Z offer increasingly convincing visual simulations, gaming engines are approaching the visual realism of such systems and are offering additional interactive features that are usually available only in more expensive immersive virtual reality systems . Additionally, the capability to have multiple individuals inhabit and navigate the space offers unique opportunities for collaboration as well as the investigation of human behaviour. Participants with internet access can be invited to access a shared virtual environment. Collaboration among users can be further enhanced by combining immersive navigation with peer-to-peer instant messaging and/or adding a voice channel. This paper analyzes these issues through research summary and the creation and user testing of a prototype based on a publicly available gaming engine. Through a series of assignments within an academic course, students in the school of architecture were asked to iteratively use and test this prototype for the collaborative exploration of designed environments. Students made their environments available for others to navigate in real-time and offer comments. A final design review was conducted in which critics were asked to enter the designed environment, explore it at will and interact with the student as well as others present in the same virtual space. This paper will illustrate some of the student projects and describe the immersive,"

summary	This paper outlines new facilities within ubiquitous media spaces supporting embodied interaction between humans and computation. We believe that the current approach to developing electronic based design environments is fundamentally defective with regard to support for multi-person multimodal design interactions. In this paper, we present an alternative ubiquitous computing environment based on an integrated design of real and virtual worlds. We implement a research prototype environment called iCube. The functional capabilities implemented in iCube include spatially-aware 3D navigation, laser pointer interaction, and tangible media. Some of its details, benefits, user experiences, and issues regarding design support are discussed.

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.

The task is to describe a concept for future access to information resources which cover the Polish (in wider international context) architectural and urban design, architectural heritage, applied arts in form of drawings, images, 3D models and VR along text explanations. In this way the database would enable access to huge resources and didactic packages. The proposed database would be primarily addressed to students of architecture, who in addition would be involved in creation of the collection, e.g. through building 3D models.

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 ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô 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‚Äôs 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.
