title	Information Rich 3D Computer Modeling of Urban Environments
source	Working Paper 35, Centre for Advanced Spatial Analysis Working Papers; London, August 2001
summary	We are living in an increasingly information rich society. Geographical Information Systems now allow us to precisely tag information to specific features, objects and locations. The Internet is enabling much of this information to be accessed by a whole spectrum of users. At CASA we are attempting to push this technology towards a three-dimensional GIS, that works across the Internet and can represent significant chunks of a large city. We believe that the range of possible uses for such technology is diverse, although we feel that urban planning is an area that can benefit greatly. An opportunity to push this ìplanning technologyî arose when CASA won a tender from Hackney Council to develop a dynamic website for community participation in the process of regenerating the Woodberry Down Estate. This is a run down part of northeast London that is undergoing a major redevelopment. CASA has developed a system that not only informs the local residents about the redevelopment process but it also enables them to use dynamic visualisations of the ìbefore and after effectsî of different plans, and then to discuss and vote on the variety of options.

summary	Several common phrases, such as “information society” or “virtual reality” point out the fact that information technology, digital tools and numerous different services via various communication networks have become crucially important factors of our western lifestyle and living environment. The trends of the society reflects naturally the working environments of the construction field, architectural discipline being amongst them. It is almost inconceivable to even imagine an architect without computer-based tools anymore. This evolutional development process has, from historical perspective, only recently started. The process is constantly evolving and rapidly increasing our possibilities to use and enjoy these modern digital fruits. The sometimes unpredictable and rapid changes in our working environment should make architects nervous about the impacts of the changes. All those delicate methods and collective traditions of the several thousand year architectural discipline(!), just simply cannot be transferred into the digital realm in a few decades. Researchers and teachers should very carefully, but still open mindedly, critically explore, analyse and adjust the so-called “modern technology” into the world of architecture, construction, design, planning – and education. We are not just “endusers”, It is we, in fact, who should define what, where and how are we willing to use it(IT). The value of information is constantly growing in our society, and in the future it will evidently be even more so. The value of information is quite hard to define with measurable or agreed concepts, but information evidently contains value-factors. The information which the architects are creating, modifying and manipulating, contains essential and valuable core data concerning the whole built environment of our society. It affects the physical surroundings of our society, in which we will be living for decades – hence, the information has a historical basis. The architectural core information also very strongly affects the quality of life of our fellow citizens – consequently, it has deep social meaning. The essentials of architectural information relies on the tradition of centuries – hence, it clearly has acknowledged cultural values, which are also extremely difficult to quantify. So how could architectural information be described? The information covers a wide range of heterogeneous concepts, items, values, methods, tools, materials, true facts, rumours, intuition and knowledge, plus a multitude of yet undefined or unpredictable factors, which still have to be watched and prepared for. Since the information deals with common and general subjects, it should also be described with common and general concepts. On the other hand as the information is also concerned with the minutiae of specific projects, the architectural information should also be described with well identified and unique entities. With our digital tools we handle all information – including architectural – more and more digitally. We have to handle and manipulate information currently as digital data, which could be understood the ”raw material” of architectural information. Digital data becomes valuable information, when some kind of meaning or purpose to somebody can be attributed to it. In the early gloomy days of ”digital architecture” in the 1960’s and 1970’s, researchers tried to describe architectural artefacts and even design process mathematically. The details of architectural information were quite difficult to describe with binary alphanumeric information of main-frame machines. The architects’ tools development then led to a trend where architects could better represent and visualize the design objects digitally. The widespread and common use of 2D-drawing and 3D-modelling tools is still a very strong trend within our discipline. In fact it is “the way” the majority of architectural information is managed today. During the last 15–20 years, so-called conceptual modelling or product data modelling, done in various technical and construction field research units worldwide, has from one viewpoint clarified the basis and essence of architectural information. Hence, it’s not only CAD-software application development, but also elementary and theoretical research that gives us valuable help to survive among the ever growing seas of terabits of data in the future to come. Architectural information is something that simply cannot be described just with DWG-drawings or dummy scanned photographs any more. Although drawings and photos may contain very important bits of architectural documentation, we need ntimes more “complexity layers”, concepts and tools to manage and understand the essence of architectural information today. A proper way to manage the data we are working with, has to cover the whole architectural discipline. The methods and tools also have to be valid and flexible for several decades in the future.

title	Web-Based Virtual-Reality for Collaboration on Urban Visual Environment Assessment
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 781-794
summary	This research aims to facilitate public participation in urban landscape visual assessment (ULVA). To support virtual collaboration in ULVA, it is desirable to provide both quantitative analysis and 3D simulation over the Internet. Although the rendering of urban models in common web browser plug-ins often lacks vividness compared with native workstation applications, the integration of VRML modeling and Java programming proves effective in sharing and rendering urban scenes through a familiar web interface. The ULVA simulation supports not only static scene rendering, but also interactive functional simulations. They include the viewpoint setting up, view corridor and panorama generation. Although popular VRML viewers such as CosmoPlayer provide similar functions, users are often disoriented by the interface. The obfuscation inhibits people’s immersion in the virtual urban environment and makes the assessment inconvenient. To eliminate such disorientation and improve users’ feelings of immersion, we integrate both a two-dimensional map and a three-dimensional model of the urban area in the user interface. The interaction between 2D map and 3D world includes the matching of avatar positions, visualization of avatar posture, and the setting up of viewpoints and view corridors. To support a web-based urban planning process, the system adopts client/server architecture. The city map is managed by a specific database management system (DBMS) on the server side. Users may retrieve information for various “what if” simulations. The system automatically remodels the virtual environment to respond to users’ requests.

title	Realism vs. Reality in Digital Reconstruction of Cities
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The digital reconstruction of existing cities using virtual reality techniques is being increasingly used. For consultants, municipalities and planning departments these models provide decision support through visual simulations (El Araby, 2001). For academia they provide a new tool for teaching students urban design and planning (Okeil, 2001). For authorities they provide a tool for promoting the city on the world wide web trying to attract more businesses and tourists to it. The built environment is very rich in detail. It does not only consist of open spaces surrounded by abstract buildings but it also includes many smaller objects such as street furniture, traffic signs, street lights, different types of vegetation and shop signs for example. All surfaces in the built environment have unique properties describing color, texture and opacity. The built environmentis dynamic and our perception is affected by factors such as pedestrian movement, traffic, environmental factors such as wind, noise and shadows. The built environment is also shaped by the accumulation of changes caused by many influences through time. All these factors make the reconstruction of the built environment a very complex task. This paper tries to answer the question: how realistic the reconstructed models of urban areas can be. It sees “Realism“ as a variable floating between three types of realties. The reality of the physical environment which we are trying to represent. The reality of the digital environment which will host the digitally reconstructed city. And the reality of the working environment which deals with the problem of limitation of resources needed to digitally reconstruct the city. A case study of building a 3D computer model of an urban area in the United Arab Emirates demonstrates that new time-saving techniques for data acquisition can enhance realism by meetingbudget limitations and time limitations.

title	Spatial Orientation in Virtual Environments
source	Delft University of Technology
summary	Recently, a growing interest can be detected in the application of Virtual Environment (VE) technology as an operator interface. VEs are three-dimensional computer-generated images that can be shown on a conventional monitor, on a large screen display, or on a head-mounted display. In order to use these three-dimensional interfaces for finding and retrieving information, the user must be able to spatially orient themselves.Different types of VE technology are available for navigating in these VEs, and different types of navigation can be enabled. A choice has to be made between the different options to enable good spatial orientation of the user. There are two main types of VE interfaces: an immersive interface that provides rich sensory feedback to the user when moving around in the VE, and a non-immersive interface that provides only visual feedback to the user when moving around in the VE. Furthermore, navigation through the VE can either be continuous providing fluent motion, or can be discontinuous which means that the viewpoint is displaced instantaneously over a large distance.To provide insight into the possible effects of these options a series of nine experiments was carried out. In the experiments the quality of spatial orientation behaviour of test subjects is measured while using the different types of interface and the different types of navigation.The results of the experiments indicate that immersive navigation improves the perception of displacement through the VE, which in turn aids the acquisition of spatial knowledge. However, as soon as the spatial layout of the VE is learned the two types of navigation interface do not lead to differences in spatial orientation performance. A discontinuous displacement leads to temporary disorientation, which will hinder the acquisition of spatial knowledge. The type of discontinuous displacements has an effect on the time needed for anticipation. The disorienting effects of a discontinuous displacement can be compensated for by enabling cognitive anticipation to the destination of the displacement.These results suggest that immersive navigation might only be beneficial for application domains in which new spatial layouts have to be learned every time or in domains where the primary users are novices. For instance, in training firemen to teach them the layout of new buildings with VE, or in using architectural walkthroughs in VE to show new building designs to potential buyers. Discontinuous movement should not be allowed when exploring a new environment. Once the environment is learned and if fast displacement is essential then discontinuous displacement should be preferred. In this case, the interface designer must make sure that information is provided about the destination of a discontinuous displacement.

title	Urban digital media: facilitating the intersection between science, the arts and culture in the arena of technology and building
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 457-466
doi	https://doi.org/10.52842/conf.caadria.2010.457
summary	The research presented in this paper investigates ways of providing better design applications for technologies in the field of Urban Digital Media (UDM). The work takes an emergent approach, evolving a design strategy through the early engagement of stakeholders. The paper discusses research in a design-led creative intersection between media technology, culture and the arts in the built environment. The case study discusses opportunities for the enhancement of a university campus experience, learning culture and community, through the provision of an integrated digital presence within campus architecture and urban spaces. It considers types of information architecture (Manovich, 2001) and designs for use in urban settings to create communication-rich, advanced and interactive designed spaces (Haeusler, 2009). The presented research investigates how to create a strategy for display technologies and networked communications to transform and augment the constructed reality of the built environment, allowing new formats of media activity.

doi	https://doi.org/10.52842/conf.acadia.2001.242
summary	The paper describes development of a large-format panoramic display environment. Unlike the ‘window-on-the-world’ metaphor associated with small displays, immersive environments foster a sense of ‘being-in-the-world’. That raises a question: Which aspects of human-computer interaction and information perception scale up or change substantially from small displays to immersive environments? The paper first describes implementation of our display environment, projects being explored in it, and motivates a focused research agenda. Finally, the paper describes an experiment to study differences in spatial judgments by subjects while working in traditional and immersive environments.

doi	https://doi.org/10.52842/conf.ecaade.2001.417
summary	On the occasion of a presentation on a city model for Graz at the eCAADe-conference in Weimar (2000), some attendees informed us about their previous work in this field and the idea of preparing a working session with collegues involved in 3-D city modeling was born. During the initial phase of research for this eCAADe conference activity it turned out that a large number of city models has been created in the course of time for different reasons resp. purposes. Therefore a rich variety in the production of city models can be noticed. This working session on 3-D city modeling brings together experts focusing on different aspects concerning the creation and use of city models, such as data input, data structure, data storage and data quality. Also the definition of a perspective on the future of 3-D city modeling can be regarded as an important topic. In this paper a rough overview on the different submissions will be presented. Furthermore three blitz statements are incorporated as time was too short to produce a full paper. Both with the individual contributions as with this overview paper it is intended to present a knowledge-base to this working field. Finally, the start for a growing bibliography was made in order to support future work in this area.

doi	https://doi.org/10.52842/conf.acadia.2001.372
summary	This paper presents research on a piece-based construction information system called PCIS(pronounced “pieces”) first published as a visual information concept at ACADIA’96, Tucson. After more than five years of development it has evolved into a multidimensional visual information system for design and construction. It includes a piece-based anatomical construction model layered according to a work breakdown structure; a dataTheater that surrounds the model as an index to plans, elevations, sections, and details; and a dataWorld with cameras fixed to the intersections of its latitudes and longitudes to add context and perspective. A standard services matrix (SSM) controls layer visibility and camera settings. PCIS can be “played” to access archived resources; support design development, analyze and resolve preconstruction conflicts, and coordinate construction activities. Current research will be used to demonstrate how PCIS might be valuable to increase the potential for technical cooperation, collaboration, and communication by literally aligning the points of view of architectural, engineering, and construction methodology.

title	CAD Study in Visual Analysis of the Visual Sustainability for China Urban Natural Landscape Planning
source	Chinese University of Hong Kong
summary	In this thesis a GIS-based CAD system prototype of evaluating visual quality of urban natural landscape environment is presented. This prototype is an indispensable component of the integrative Visual Sustainability research, and offers a calculable and visualizable technique to urban visual natural landscape assessment. This scientific method provides precise data to estimate the visibility of natural landscape in urban construction actuality. Furthermore, it can also work out supporting information for maintaining and protecting valuable visual landscape resources in further planning. Introduction of this methodology intends to improve the natural landscape cooperation in China urban planning through visual protection. Combining with popular CAD software such as AutoCAD and Microstation, the research team uses ArcView GIS software and its 3D Analyst extension to accomplish a set of research procedure, which includes data modification, model making, viewshed and view sensibility analysis. In addition, this system can create simultaneous 3D scenes or hire other information media as reference tools for professional analysis, design consultation and intercommunication. The core technologies of this proposed system are viewshed calculation and overlay analysis. In viewshed analysis, human visual characteristics are simulated by a series of ergonomics parameters of viewpoints. Viewshed of each viewpoint can be calculated into vector data and mapped by polygons identifying which region is visible and which is not. Overlay function of the proposed system is used in visual sensibility analysis to achieve the division of higher visual sensible area which indicates the common visible area from different viewpoints. Additionally, viewshed maps and visual sensibility results can add more information to mark out the areas that can satisfy certain visual parameters such as appropriate visual angle or visual distance. These overlaying results can visualized the visible areas into hierarchical visual perception quality categories in order to define the visual landscape significance of particular planning regions. A case study was operated to evaluate this system. The case is in Zhongshan city, Guangdong Province of China. Jinzishan hill region is the study site that picked by collaborating discussion of research team and the local government. It is located on the edge of urban built-up area. Jinzishan massif is the prominent landscape element of the surrounding environment. There are three topics in Jinzishan visual perception in this paper. The first topic is the visual quality evaluation of the intersections of its surrounding road system. The second is the integrated visual perception of two main roads called Qiwandao and Bo‚Äôailu. Finally is the analysis of the hill skyline visual quality in surrounding area. The analysis results in GIS vector data can be converted into popular data format and combined with other spatial information for practical application. And comments for future urban planning are collected and analyzed by professional responses to the computer-generated information investigation.

title	Architecture and the Internet: Designing Places in Cyberspace

doi	https://doi.org/10.52842/conf.acadia.2001.230
summary	Cyberspace, as the information space is called, has become accessible in the past decade through the World Wide Web. And although it can only be experienced through the mediation of computers, it is quickly becoming an alternative stage for everyday economic, cultural, and other human activities. As such, there is a potential and a need to design it according to place-like principles. Making places for human inhabitation is, of course, what architects, landscape architects, town planners, and interior designers have been doing in physical space for thousands of years. It is curious, therefore, that Cyberspace designers have not capitalized on the theories, experiences, and practices that have been guiding physical place-making. Rather, they have adopted the woefully inadequate ‘document metaphor’: instead of ‘web-places’ we find ‘web-pages.’ 3D environments that closely mimic physical space are not much better suited for making Cyber-places: they are, by and large, devoid of essential characteristics that make a ‘place’ different from a mere ‘space,’ and only rarely are they sensitive to, and take advantage of, the peculiarities of Cyberspace. We believe that this state of affairs is temporary, characteristic of early adoption stages of new technologies. As the Web matures, and as it assumes more fully its role as a space rather than as means of communication, there will be a growing need to design it according to place-making principles rather than document-making ones. By looking at physical architecture as a case study and metaphor for organizing space into meaningful places, this paper explores the possibility of organizing Cyberspace into spatial settings that not only afford social interaction, but, like physical places, also embody and express cultural values. At the same time, because Cyberspace lacks materiality, is free from physical constraints, and because it can only be ‘inhabited’ by proxy, these ‘places’ may not necessarily resemble their physical counterparts.

summary	This paper explores the idea that 3D city models integrated with hypermedia systems can facilitate the sense of belonging to a place. 3D models are powerful tools for buildings and urban space analysis as artifacts, which synthesize men’s reality and aspirations. As such, combined with hypermedia resources, they can strengthen the spectator’s actual experience in the analyzed space. The focus of the investigation is 3D models constructed to represent and analyze city evolution. The experience of developing the models of Latin American cities – Rio de Janeiro, Brazil and Havana, Cuba – developed at PROURB (Faculty of Architecture and Urbanism, Federal University of Rio de Janeiro) is explained with an overview of its methodology.

title	Visualization of Flow Data in Photo-realistic Virtual Environment
source	Helsinki University of Technology, Espoo, Finland
summary	Virtual reality technology has been adopted in many different fields and new application areas are searched continuously. At the moment virtual reality has been applied separately for instance to scientific visualization and illustration of architectural spaces. In this work, a photo-realistic room model and a visualization of an air flow inside the room has been combined. The integrated illustrative three-dimensional model is presented within an immersive virtual environment. The first part of the work covers scientific visualization and virtual reality implementation techniques. The visualization review begins with a discussion about human percepion of visual information and proceeds with an introduction to three-dimensional visualization. The focus is on illustration of a flow data produced as a result of a computational simulation. The flow visualization techniques utilizing all three dimensions are discussed and many examples of different graphical elements are presented. Virtual reality is examined from technical solutions point of view. The features having effect on the quality of a virtual experience are discussed and three different commonly used display techniques are introduced. The hardware of Experimental Virtual Environment -facility at Helsinki University of Technology is given as a detailed example. The implementation of a visualization software is described in the applied part of this thesis. Discussion covers the evaluation of different software tools, the tool selection process, and a detailed description of the design principles and implementation of the software. The different visualization solutions are also justified in this part. In the implementation, the real-time system requirements and utilization of all three dimensions have been taken into account. Finally, the results and their meaning are discussed and the performance of the implementation is evaluated. The applied part successfully integrated the room model and the flow visualization in an interactive virtual environment.

summary	ReSpace is a teaching module, which entices students in a playful way to work with computers and motivates them to think more deeply about the abstract idea of space. The goal of ReSpace is to enhance the concept of space by augmenting its content with additional levels of information like statements about emotions, by referring to senses, delineating impressions or telling stories and inducing memories. ReSpace takes advantage of the possibilities offered by virtual environments in the transfer of information and suggests space as a metaphor for the communication of ideas, knowledge and experiences about space. In this paper the module ReSpace taught by the author is described. Its central theme is the representation and communication of oneís notion, perception, and interpretation of space with the help of a 3D, interactive, virtual, environment. http://alterego.arch.ethz.ch

title	The visual harmony between new and old materials in the restoration of historical architecture: A study of computer simulation
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In the research of historical architecture restoration, scholars respectively focus on the field of architectural context and architectural archeology (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000) or on architecture construction and the procedure of restoration (Shi, 1988, 1989; Chiu, 1990). How to choose materials and cope with their durability becomes an important issue in the restoration of historical architecture (Dasser, 1990; Wang, 1998).In the related research of the usage and durability of materials, some scholars deem that, instead of continuing the traditional ways that last for hundreds of years (that is to replace new materials with old ones), it might be better to keep the original materials (Dasser, 1990). However, unavoidably, some of the originals are much worn. Thus we have to first establish the standard of eliminating components, and secondly to replace identical or similar materials with the old components (Lee, 1990). After accomplishing the restoration, we often unexpectedly find out that the renewed historical building is too new that the sense of history is eliminated (Dasser, 1990; Fu, 1997). Actually this is the important factor that determines the accomplishment of restoration. In the past, some scholars find out that the contrast and conflict between new and old materials are contributed to the different time of manufacture and different coating, such as antiseptic, pattern, etc., which result in the discrepancy of the sense of visual perception (Lee, 1990; Fu, 1997; Dasser, 1990).In recent years, a number of researches and practice of computer technology have been done in the field of architectural design. We are able to proceed design communication more exactly by the application of some systematic softwares, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and so on (Lawson, 1995; Liu, 1996). The application of computer technology to the research of the preservation of historical architecture is comparatively late. Continually some researchers explore the procedure of restoration by computer simulation technology (Potier, 2000), or establish digital database of the investigation of historical architecture (Sasada, 2000; Wang, 1998). How to choose materials by the technology of computer simulation influences the sense of visual perception. Liu (2000) has a more complete result on visual impact analysis and assessment (VIAA) about the research of urban design projection. The main subjects of this research paper focuses on whether the technology of computer simulation can extenuate the conflict between new and old materials that imposed on visual perception.The objective of this paper is to propose a standard method of visual harmony effects for materials in historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example).There are five steps in this research: 1.Categorize the materials of historical architecture and establish the information in digital database. 2.Get new materials of historical architecture and establish the information in digital database. 3.According to the mixing amount of new and old materials, determinate their proportion of the building; mixing new and old materials in a certain way. 4.Assign the mixed materials to the computer model and proceed the simulation of lighting. 5.Make experts and the citizens to evaluate the accomplished computer model in order to propose the expected standard method.According to the experiment mentioned above, we first address a procedure of material simulation of the historical architecture restoration and then offer some suggestions of how to mix new and old materials.By this procedure of simulation, we offer a better view to control the restoration of historical architecture. And, the discrepancy and discordance by new and old materials can be released. Moreover, we thus avoid to reconstructing ¡§too new¡¨ historical architecture.

title	The concept of Carrying in Collaborative Virtual Environments
source	Stellingwerff, Martijn and Verbeke, Johan (Eds.), ACCOLADE - Architecture, Collaboration, Design. Delft University Press (DUP Science) / ISBN 90-407-2216-1 / The Netherlands, pp. 195-208 [Book ordering info: m.c.stellingwerff@bk.tudelft.nl]
summary	Collaborative Architectural Design can take place within a virtual environment with a team of remote but virtually present people. However, in most virtual environments, the ability to perform actions is still limited to the availability of some interactive objects and a set of tools for the specific purposes of the system. As the interface of most systems is designed for unshared use, the graphic feedback signals are limited to local information about the state of objects and tools. If multiuser interaction is added to such Virtual Environments, many new possibilities and problems emerge. Users of shared applications should not only be informed about the state of local objects, tools and their own actions, they should also be made aware of what the other users undertake. Aspects, which are in daily life so obvious, should be restudied thoroughly for the application within Virtual Environments for Collaborative Design. Much research has to be undertaken in order to make such virtual places as intuitively interactive as ordinary shared working places. The 'concept of carrying', which is proposed and explained in this paper, is expected to become a useful metaphoric mechanism for solving several issues related to Spatial User Interfaces (SUI's) and Collaborative Virtual Environments (CVE's). The visual feedback from 'carrying-events' should provide more mutual understanding about ongoing processes in shared applications and it should add a more 'natural' interface for processes concerning people, tools and content in virtual and digitally augmented environments. At the start of this paper some basic human action patterns for tasks on a 2Ddesktop are compared to tasks in a 3D-environment. These action patterns are checked for their implementation in Windows Icons Menus and Pointer (WIMP) interfaces and Virtual Reality systems. Carrying is focused upon as an important interactive event in Virtual Environments. Three carrying actions related to Collaborative Architectural Design are explained by means of prototypes in Virtual Reality Modeling Language (VRML). Finally the usefulness of a general carrying concept as part of a new Visual Language is considered. The research at hand is in its first exploring phases and draws from a running PhD research about SUI's for Context Related Architectural Design and from recent experiences in CVE's.

title	Design + Virtual Modeling: Course Integration on a Large Scale
source	Marjanovic I and Robinson C (eds) Intersections: Design Education and Other Fields of Inquiry, Proceedings of the 22nd National Conference on the Beginning Design Student, Ames, Iowa, April 2006, 309-313
summary	Starting in 2001 a group of faculty at the University of Wisconsin – Milwaukee School of Architecture and Urban Planning undertook a three year effort to integrate introductory studio with introductory computer-aided design. Each year 160 incoming sophomores begin their first design studio. They also receive a laptop computer and begin concurrent enrollment in an introductory computer course entitled Virtual Modeling. Students participate in studio projects, computer assignments, hand drawing tutorials, computer tutorials, studio course lectures and computer course lectures. This takes the dedicated effort of four faculty members and five graduate teaching assistants. The goals of this paper are 1) to describe the evolution of this large-scale integration effort, 2) to identify key success factors, and 3) to describe the impact on our students’ beginning design education. The paper provides a balanced perspective by discussing both benefits and challenges. It begins with more concrete information and moves gradually into deeper issues.

title	Visualizing Building Occupancy Pattern on Campus
source	Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 398-404

summary	This paper addresses the problem of information opacity that planners and university administrators have when they have multiple sets of data that are not interconnected and how these data can be visualized. The visualization of building occupancy pattern on campus is used as an example to illustrate how this general problem can be addressed through a database driven effective visualization that supports decision-making. This paper proposes a solution using web-based 3D Virtual Reality Modeling Language (VRML) animation dynamically generated from a database and describes a prototype in progress. The prototype displays a broad overview of building occupancy patterns across campus through 3D animation of occupancy over time. From the overview, users can navigate further to find out the details of occupancy throughout the day for specific buildings on campus.

summary	This paper presents a recently finished course of eight weeks where CAAD skills, design methodology, and architectural theory are combined to discuss possible perspectives on the use of the computer in design, and its influence on architecture. In the course, three contemporary architects were studied; Peter Eisenman, Ben van Berkel, and Greg Lynn. Each was discussed on aspects of ontology (which are the elements of discourse), design method (design process and organization of the process), and the use of the computer (techniques and approaches). These were linked with design theory, architectural theory, and CAD-theory. The reflection on the work of the architects resulted in a number of design methods for each architect. The design methods were adapted to the available technologies in the university as well as to the scope of the exercise, since the period of eight weeks for an exercise cannot compete with design processes in practice that take many participants and much time. The students then applied the design methods to a design task: student housing and an exhibition pavilion on the campus area of the university. The task was so devised, that students could focus on either architectural or urban design level with one of the design methods. Also, the choice of architects and accompanying design methods was made in such a way that students with low, medium, and advanced computer skills could take part in the course and exercise. In a workshop held at the Czech Technical University (CVUT) in Prague, the same procedure was used in a one-week period for a different design task, but in an otherwise almost identical setting with respect to the CAAD software used. The methods and material were easily transferred to the other setting. The students were able to cope with the task and produced surprising results in the short time span available. The paper will provide an overview of the course, discuss the pedagogical implications of the work, and discuss how this particular work can be generalized to incorporate other architects and approaches.
