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.

title	Interactive Walkthrough Environments for Simulation
source	University of California at Berkeley
summary	This thesis describes a second-generation walkthrough framework that provides extensive facilities for integrating many types of third-party simulation codes into a large-scale virtual environment model, and puts it in perspective with first-generation systems built during the last two decades. The framework provides an advanced model database that supports multiple simultaneous users with full consistency semantics, system independent storage and retrieval, and efficient prefetching and object reconstruction techniques to support second and third-generation walkthrough systems. Furthermore, our framework integrates support for scalable, distributed, interactive models with plug-in physical simulation to provide a large and rich environment suitable for architectural evaluation and training applications. A number of third-party simulations have been integrated into the framework, including dynamic physical interactions, fire simulation, multiple distributed users, radiosity, and online tapestry generation. All of these simulators interact with each other and with the user via a data distribution network that provides efficient, optimized use of bandwidth to transport simulation results to clients as they need them for visualization. These diverse simulators provide proof of concept for the generality of the framework, and show how quickly third-party simulations can be integrated into our system. The result is a highly interactive distributed architectural model with applications in research, training, and real-time data visualization. Finally, an outlook is given to a possible third generation of virtual environment architectures that are capable of integrating different heterogeneous walkthrough models.

title	Clients, architects, houses and computers: Experiment and reflection on new roles and relationships in design
doi	https://doi.org/10.52842/conf.acadia.2001.100
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. 100-109
summary	This paper reports on recent work that focused on the potential impact of standard computer technology on the relationship between client and architect in the context of residential design. A study of software applications a client could use to develop and evaluate ideas exposed the dearth of software available for the design of spatial complexity by individuals without advanced computer skills, and led to the design of a specific piece of software we call “Space Modeler.” It was prototyped using off-the-shelf virtual reality technology, and tested by a group of freshmen students. The paper discusses the specificities of the software and provides analysis and reflection based on the results of the test, both in terms of design artifacts and users’ comments. The paper concludes that the evolution of the interface to electronic environments is a matter of interest for those concerned with rethinking the training, role and activity of the architect. In the near future prospective homeowners may be able to experience and experiment with the space of their home before it is built. How can the profession embrace new information technology developments and appropriate them for the benefits of society at large?

title	Digital Charrette: A Web Based Tool to Supplement the Admission Procedure to Graduate Architectural Degree Programs
source	Texas A&M University
summary	The NAAB (National Architectural Accrediting Board Inc.), as an evaluator of architectural education in the United States has established both graduate architectural curriculum criteria and student performance criteria expected to be fulfilled by the student at the time of graduation. To fulfill these standards set by the NAAB, the graduate selection committees of architecture schools require the ability to predict graduate design studio performance of the applicants. The high percentage of international applicants suggests the necessity of a standardized evaluation tool. This research presents a standardized web based testing environment titled Digital Charrete‚ that would contribute towards the fair evaluation of applicants to graduate architectural degree programs. Spatial ability is related to Design and Visualization skills‚, a part of the NAAB criteria, and also associated with design studio performance of architecture students. The Digital Charrette is a VRML environment within which spatial exercises are administered. It is designed to supplement the current admission procedure, and would enable the selection of students with greater potential to perform well in graduate architectural design studios. This research is also an attempt to understand the implications of using virtual three-dimensional environments for such testing purposes. The ability of this web based tool to predict student performance in architectural design studios is investigated. Finally, the user reactions to testing in a virtual three-dimensional environment and timed tasks are included in this study. Analysis of the results showed that the test takers thought the Digital Charrette was a good evaluator of their spatial ability. The study population showed a preference for paper-based media in the pre-task analysis. A huge percentage of the study population found the Digital Charrette Œfun to do‚ and Œchallenging‚. The major drawback of this study was that the VRML environment was unable to render itself for testing purposes in a way that the medium would not hinder the test takers‚ performance. This may also be considered a cause for a relatively smaller percentage of success amongst test takers. The study population however unanimously considered the concept of the Digital Charrette, i.e. testing in virtual environments, significant to evaluation of architecture students.

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	REACTIVE VIRTUAL ENVIRONMENTS IN BUILDING DESIGN
source	Proceedings: SCI 2001, The Fifth Multi-Conference on Systemics, Cybernetics and Informatics, Orlando, Florida, USA, July 22 - 25, 2001. http://www.iiis.org/sci/
summary	This paper presents the first prototype of a reconfigurable Virtual Environment (VE). The objective of the system is to link 3D Intelligent Virtual Environments to interactive planning systems. This type of system makes possible interactive solutions where the user refines a possible configuration and enables the system to generate a complete new solution enforcing all the design constraints, previously programmed. In this first prototype we link our constraint solver with the visualization engine so that the solution produced by the constraint solver is displayed in a VE.

source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 585- 597
summary	For a long time the Architecture-Engineering-Construction (AEC) community has had difficulty in communicating the content of their work, not only the various specialties involved, but also to their clients. Studies (Doorst and Cross 2001; Bakhtin 1994) suggest the importance of multi-role collaborative environments in supporting design processes. We are developing a Multi Level Design Review Tool for the AEC industry which allows multiple actors to congregate and interact as agents around a central Building Model. It merges real-time virtual 3D visualization technologies with Industry Foundation Classes (IFC) to support both high levels of semantic content and seamless interoperability.

summary	One of my tasks while working for Arup in Los Angeles was to teach engineers how to design and communicate using the same tools as architects. As increasing numbers of clients provided us with virtual massing and conceptual models to work from, my colleagues began to acknowledge the need to develop engineering solutions within these same virtual environments. So, my challenge was to not only utilize 3D modeling for visualization but also for design, analysis and production.

title	WHAT DOES COMPUTER AIDED DESIGN OFFER FOR PRODUCING LIVABLE BUILDINGS IN THE 21ST CENTURY?
source	Proceedings of the Livable Environments and Architecture International Congress (LIVENARCH 2001). July 4-7, 2001, Trabzon, Turkey, pp. 278-282.
summary	Designing livable buildings has always been a major concern for architects but they are often criticized on account of failing in this aim. However, this is not only due to the ignorance of the designers, but also of the complexity of the factors that are essential to design but difficult to incorporate the design process. Buildings are shaped and occupied under several dynamically changing conditions and paper-based media and conventional Computer Aided Design (CAD) tools are inefficient in representing them. This paper aims to discuss the changing role of digital media for architectural design in response to the increasing complexity of design processes. Some proposals, supported by recent technological innovations, are suggested for the future and they are compared with the conventional uses of CAD. It is claimed that in the 21st century, the main advantage of using computers will be to dynamically simulate buildings in time in highly visualized virtual environments to evaluate the future performance of proposed designs. The design model will not only look as if it were real, but it will also “behave” as if it were real so as to provide dynamic and intelligent response. The two key technologies for the development of such modeling, virtual reality and object-oriented programming are addressed and four promising application areas for near future (evaluation of user-building interaction, visualization of environmental factors, construction scheduling, and combined CAD-GIS) are discussed. Some important considerations for the development of dynamically simulated virtual models are analyzed and suggestions are made for further research.

title	Improving Air Quality of Public Transport Interchanges - Design Strategies to integrate CFD simulation in early design process
doi	https://doi.org/10.52842/conf.ecaade.2001.054
source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 54-59
summary	Indoor public transport interchanges (PTI) are ubiquitous in Hong Kong. In the hyperdense urban context, land use has been optimized through the design of complex public facilities. Owing to the use of diesel engines by public transport vehicles, the main pollutants are sulphur dioxide, nitrogen dioxide and carbon monoxides. Although the Hong Kong Government took measurements to improve the air quality in PTI, unfortunately, the problem has not been solved up to now. To effectively integrate the architectural design with efficient ventilation system to remove pollutants, designers and engineers need to predict and visualize the pollutant concentration and the time history of pollutant transfer during early stage of design. With time dependent computational fluid dynamics (CFD) simulation and the scientific visualization technology, architects and engineers could visualize the pollutant distribution in real time, and “what-if” scenarios could be investigated collaboratively. In this project, we have established a time-dependent CFD multiphase model to describe the pollutant concentration and the time history of pollutant transfer in PTI. On the basis of simulation results, several new design schemes are proposed and tested.

title	Strategy on applying computational fluid dynamic for building performance evaluation
source	Automation in Construction 10 (3) (2001) pp. 327-335
summary	Predicting and evaluating building performance plays an important role in the training of responsible architects. Building performance includes issues such as: structural stability, acoustic quality, natural lighting, thermal comfort, and ventilation and indoor air quality. These types of analyses are often laborious, non-intuitive, and non-graphical. As a result, these important issues do not arouse the enthusiasm of architecture students or building professionals. The Chinese University of Hong Kong (CUHK) research team proposes to explore and develop a long-term strategy to apply scientific visualization on teaching and research in environmental technology and building performance. This paper presents the development process and results of research projects for applying computational fluid dynamics (CFD) on building performance evaluation. CFD On-line Teaching project's aim is to develop a web-based training course for architecture students to apply CFD simulation on design problem solving. Each lesson not only illustrates basic principles regarding airflow in the building design, it also contains CFD sample files with predefined flow cells for students to test different concepts. GiLin Temple project's aim is to apply CFD simulation on investigating the wind resistance of Tong Dynasty heavy timber structure. Airflow information generated in the project includes the visual representation of the pressure distribution and velocity field on all slices through the temple, and the tracking of particles as they flow around or through a building. The China housing residential airduct study focuses on simulating the indoor airflow regarding the airduct design of China Experimental Urban Housing Scheme. The visual representation of the pressure distribution and velocity field in the airducts provides vital information for helping China Housing Research Center improve the current design.

title	Learning and Contamination in Virtual Worlds
source	International Conference on Generative Art
summary	The most recent advances of artificial life scientific research are opening up a new frontier: the creation of simulated life environments populated by autonomous agents. In these environments artificial beings can interact, reproduce and evolve [4, 6, 15], and can be seen as laboratories whereto explore the emergence of social behaviors like competition, cooperation, relationships and communication [5, 7] . It is still not possible to approach a reasonable simulation of the incredible complexity of human or animal societies, but these environments can be used as a scientific orartistic tool to explore some basic aspects of the evolution [1, 2, 3, 9, 10, 11, 12, 13, 14]. The combination of these concepts with robotics technology or with immersive-interactive 3D environments (virtual reality) are changing quickly well known paradigms like digital life, manmachineinterface, virtual world. The virtual world metaphor becomes interesting when the artificial beings can develop some form of learning, increasing their performances, adaptation, and developing the ability to exchange information with human visitors. In this sense the evolution enhances the creative power and meaningful of these environments, and human visitors experience an emotion of a shift from a simplified simulation of the reality to a real immersion into an imaginary life. We may think that these realization are the first sparks of a new form of life: simulated for the soft-alife thinkers, real for the hard-alife thinkers, or a simple imaginary vision for the artists.

title	Colour appearance in virtual reality: a comparison between a full-scale room and a virtual reality simulation
source	AIC Colour 2001, The 9th Congress of the International Colour Association, Rochester, NY.
summary	The main goal of our project is to make VR applications usable for the planning of light and colour. To enable reliable simulations, we both need to develop better rendering methods and carefully study the appearance of light and colour in real rooms and in virtual environments. Assessments of real rooms are compared to simulations of the same rooms in immersive Virtual Reality (3D-cube). In this paper, we will present the outcome of a pilot study and discuss specific problems associated with the prospect of comparing reality to Virtual Reality. We will account for the experience of the room and go into details on the experience and perception of light. Indeed, the problems of getting enough light in the 3D-cube and of simulating the light situation of a real room affect colour appearance.

title	The Nature of Non-Physical Space - Or how I learned to love cyberspace wherever it may be
doi	https://doi.org/10.52842/conf.ecaade.2001.208
source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 208-213
summary	More designers are concerned with the occupation of the virtual world, through immersive techniques, for example, than in using it as a means for conceptualising and theorising architectural space. The paper examines how architects think about space and how our consideration of nonphysical space might assist in spatial theory and in teaching. It also considers cyberspace fiction both in writing and film to see how it might help us think about space in a more liberating way. Architects and architectural teaching tends to focus on space as an element of construction rather than a theoretical proposition. By discussing imaginary spaces in greater depth we could encourage students to think about space and spatial concepts in a less rigid way. In particular the paper addresses the issues of interaction and transactions in these environments and how information is represented and accessed in an apparently threedimensional manner. In his book ‘Snow Crash’, Neil Stephenson deals with many ideas concerning not only architectural space but also universal space and its organisation in space and time. He uses metaphor in his depiction of the ultimate in information gathering and management. These are compelling ways in which to communicate ideas about threedimensional thinking, and information collection and management to students of architecture as well as helping architects with the theory and visualisation of non-physical space.

title	Practical Navigation in Virtual Architectural Environments
source	Helsinki University of Technology, Espoo, Finland
summary	The interest towards virtual reality (VR) and virtual environments (VE) is growing all the time. The applications being developed for VE run a wide spectrum, from games to business planning. This thesis concentrates on navigation in virtual architectural environments, movement in worlds that are very similar to our own. Navigation in a virtual world should be practical, intuitive and simple. Unfortunately, it is very often far from that - for some reason the usability issues in VEs have been usually left with little attention. Currently it is easy for a user to get lost and disoriented when traveling in a VE. This situation must change, navigating through virtual environments can no longer be considered a task reserved for the experts only. 3D-worlds and architectural applications for the common user require new, intuitive interface techniques. This thesis addresses issues related to both physical and cognitive aspects of navigation as well as theoretical models that bind them together. In the technology survey of this thesis, the virtual environment technology is presented. Different visual display systems, new input devices and some 3D user interface design aspects are described. The literature survey section discusses the main issues concerning navigation theory. The two parts of navigation, travel and wayfinding, are described in detail. The major challenges are discussed and some solutions and various research results are presented. A major part of the thesis consists of the description of HCNav, a new navigation system developed by the author. The system was constructed for use in the virtual room at Helsinki University of Technology. The purpose of HCNav is to provide a very intuitive and practical navigation interface. Three new experimental input devices, namely custom wand, data glove and speech recognition system, were tested. Another important part of the work is to evaluate the effectiveness of the HCNav system. A usability test was conducted to determine if the use of HCNav was actually improving navigation performance. Twelve subjects participated in a test where HCNav was compared with a traditional navigation software used previously in the virtual room. The experiment setup has been described and the results analyzed. The results are promising and show that the navigation methods adopted in HCNav are clearly better.

title	Virtual Environments for Special Needs. Changing the VR Paradigm
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 151-159
summary	The normal application of Virtual Reality is to the simulation of environments, which are in some way special - remote, hazardous or purely imaginary. This paper describes research and development work which changes the paradigm by simulating perfectly ordinary buildings for special people. Some 15% of the population have some form of physical impairment - a proportion which is likely to rise in line with an ageing population. New legislation, such as the UK Disability Discrimination Act places additional responsibility on building owners to ensure adequate access for people with an impairment and this in turn will place additional responsibility on the architect. Current methods of auditing access for new building are primitive and require the auditor to interpret plans/sections of the proposed building against a checklist of requirements specific to the special need. This paper reports on progress in the use of an immersive VR facility to simulate access to buildings for two broad classes of user: i) those with a mobility impairment; ii) those with visual impairment. In the former case, a wheelchair motion platform has been designed which allows the wheelchair user to navigate the virtual building; a brake and motor connected to the rollers on which the wheelchair sits facilitate the effects of slope and surface resistance. In the latter case, the main categories and degrees of visual impairment can be simulated allowing architects to assess the contribution of form, colour and signage to safe access.

source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 472-478
summary	Using Virtual Environment (VE) to visualize ideas from the initial steps of design, the architect is challenged to deal with perception of space, solid and void, without translations to and from a two dimensional media. In this moment, we may expect new forms of design expression. The goal of our study was to identify how designers use and communicate early design ideas by using immersive three-dimensional VEs. We explored initial intentions of 3Dimmersive design schemes, textual descriptions and collaborations within immersive VE. We set-up a series of experiments including navigation- and perception-tasks, designing in immersive VE, transcription of design, remote communication between design partners and controlled observations. The paper describes these experiments. Finally we summarize observations from this research, for instance the simplicity to interconnect design-ideas cross platforms, conclude with possible future directions of our investigation, initiating a broader research including other disciplines.

title	Beyond the math visualization - Geometrica and Stochastica
source	International Conference on Generative Art
summary	Mathematically controlled imaging process provides attractive results because of its infinite scaling capabilities with some other elements that contribute to the visualization. Its global/local and precise manipulation of parameters holds potential for realizing an unpredictable horizon of imagery. When it meets the artist's taste, this method could be a strong enough system of creation, and I have been producing images using the surfaces of hyperbolic paraboloid. On the other hand, a method absolutely free from the geometric parameter manipulation is possible with a stochastic process [1]. Like the technique of pendulum in photography, while its production rate of acceptable result is very low, its potential of generating a strong visual message is also very attractive. It is possible to set stochastic elements at any stage of the process, and conditional probability on those elements, or the hierarchy of probability management characterizes the probability distribution. Math space has no light. No gravity. No color on the math surfaces. And the math equation providesonly the boundary in 3D or higher mathematical dimensions. The fact means that artists can keep artistic reality with their unique tastes in colors on the surface and light sources, and this is the most important element of the math based imaging. Being able to give artists' own choice of colors and that the artist may take only right ones from the results of a stochastic process guarantee the motif and aesthetics of artist could be reflected onto the work.
