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.

summary A core element in the success of a virtual environment is the ease and appropriateness of the navigation process. Navigation is a two part process which consists of a facility for enabling movement [Locomotion] and sensory input to aid the navigator in finding they way around [Cognition]. Our work has focussed on Navigation in Virtual Environments for Architecture and that work is summarised here.

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 JCAD-VR: Java Collaborative Architectural Design Tool in Virtual Reality - A Java3D based scalable framework for real-time, multiplatform VR environments
doi https://doi.org/10.52842/conf.ecaade.2001.454
source Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 454-459
summary This paper proposes a framework that provides the architect with a tool that uses Virtual Reality (VR) as part of the design path. It offers the possibility to deploy a system capable of assisting the design profession during the early stages of the design process. This way VR becomes the means for a new experience where the architect can, free from constraints of the 2D world, create and manipulate the space she/he is designing. The idea upon which JCAD-VR is being built is that all the users present in the virtual world have to be able to share the same virtual environment in a “transparent fashion” where the user interface, instead of the traditional menu/windows based layout, it is part of the virtual world itself. The aim is to provide the designer with a tool for creating 3D-shapes in a shared VR environment, thus allowing the design to be shared as it evolves.

title Can simulations in VE support architects in solving complex design problems?
source Stellingwerff, Martijn and Verbeke, Johan (Eds.), ACCOLADE - Architecture, Collaboration, Design. Delft University Press (DUP Science) / ISBN 90-407-2216-1 / The Netherlands, pp. 77-82 [Book ordering info: m.c.stellingwerff@bk.tudelft.nl]
summary Building design is facing development of industrialization of the production on the one hand and more complex 'One of a Kind' products on the other. This will be for rebuilding of a large stock of existing buildings and what can be left to new production. In both cases the results of the design process have to be solid to guarantee a successful product. In both cases an integrated and careful design process is absolutely crucial. The demands on the built environment make the systems of buildings more and more complex and have to be handled by a lot of different expertise. To avoid the 'Relay Race' of today the design teams of tomorrow must work much more integrated. To make integrated solutions, which means simultaneous constrains on all systems, the experts of different fields have to understand more of how all engaged systems relate and influence each other. Communication then consists of complex situations and processes that have to be understood and related to reality. In this aspect a multidimensional Virtual Environment interface has advantages and has been successfully used in design processes in other industries. In this paper the problems that have to be studied are for example Methodical, Conceptual, Technical and Process economical.

summary This research briefly examines the importance of collaborative design in developing a multi-user, multi-tiered, networked and real-time information base system. Aspects such as navigation, interaction, communication, movements (objects or virtual camera), control, level of details, spatial design and virtual spaces will be explained to show their importance in the development of virtual world. This paper will further explore the aspects of collaborative design in the context of Army War Game Simulation System (AWAS). A generic collaborative design-based framework will be demonstrated to simulate the overall operations of a war in command-control structure of the force.

title Creating a City Administration System (CAS) using Virtual Reality in an Immersive Collaborative Environment (ICE)
doi https://doi.org/10.52842/conf.ecaade.2001.449
source Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 449-453
summary Current problems in administration of a city are found to be decentralized and noninteractive for an effective city management. This usually will result in inconsistencies of decision-making, inefficient services and slow response to a particular action. City administration often spends more money, time and human resource because of these problems. This research demonstrates our research and development of creating a City Administration System (CAS) to solve the problems stated above. The task of the system is to use information, multimedia and graphical technologies to form a database in which the city administrators can monitor, understand and manage an entire city from a central location. The key technology behind the success of the overall system uses virtual reality and immersive collaborative environment (ICE). This system employs emerging computer based real-time interactive technologies that are expected to ensure effective decisionmaking process, improved communication, and collaboration, error reduction, (Rafi and Karboulonis, 2000) between multi disciplinary users and approaches. This multi perspective approach allows planners, engineers, urban designers, architects, local authorities, environmentalists and general public to search, understand, process and anticipate the impact of a particular situation in the new city. It is hoped that the CAS will benefit city administrators to give them a tool that gives them the ability to understand, plan, and manage the business of running the city.

title The End of Methodology - Towards New Integration
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 The present paper is devoted to the deliberation on the genesis and development of designing from the point of view of the potential use of computers in the process. Moreover, it also presents the great hopes which were connected with the use of the systematic designing methods in the 1960’s, as well as the great disappointment resulting from the lack of concrete results. At this time a great deal of attention was paid to the process of design as a branch of a wider process of problem-solving. Many people believed that the intuitive methods of design traditionally used by architects were incapable of dealing with the complexity of the problems to be solved. Therefore, the basic problem was the definition of a vertical structure of the designing process, which would make it possible to optimise each process of architectural design. The studies of design methodology directed at the codification of the norms of actions have not brought about any solutions which could be commonly accepted, as the efforts to present the designing process as a formally logical one and one that is not internally “uncontrary” from the mathematical point of view, were doomed to fail. Moreover, the difficulties connected with the use of the computer in designing were caused by the lack of a graphic interface, which is so very characteristic of an architect’s workshop. In result, the methodology ceased to be the main area of the architect’s interest and efforts were focused on facilitating the method of the designer’s communication with the computer. New tools were created, which enabled both the automatic generation of diversity and the creation of forms on the basis of genetic algorithms, as well as the presentation of the obtained results in the form of rendering, animation and VRML. This was the end of the general methodology of designing and the beginning of a number of methods solving the partial problems of computer-supported design. The present situation can be described with the words of Ian Stewart as a “chaotic run in all directions”. An immediate need for new integration is felt. Cyber-real space could be a solution to the problem. C-R-S is not a virtual reality understood as an unreal world. Whilst VR could be indeed treated as a sort of an illusion, C-R-S is a much more realistic being, defining the area in which the creative activities are taking place. The architect gains the possibility of having a direct contact with the form he or she is creating. Direct design enables one to creatively use the computer technology in the designing process. The intelligent system of recognising speech, integrated with the system of virtual reality, will allow to create an environment for the designer – computer communication which will be most natural to the person. The elimination of this obstacle will facilitate the integration of the new methods into one designing environment. The theoretical assumptions of such an environment are described in the present paper.

summary The “cybrid architecture” has been defined like integration of physical and digital spaces. Based on the capability of electronic media to generate virtual environments (cyberspaces) which could be related to buildings. However, theoretical studies and contemporary works reveal a more complex relationship between media and constructions. Expressed in architectural characteristics that constitutes a new spatial quality, named here projected space. Hence the paper argues that “cybrid architecture” is not technological, but is a modification of conventional architectural space due to cultural evolution.

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.

summary The Isthmia Roman Bath is located in Greece overlooking a great ravine on the Isthmus of Corinth. It was in use during the 2nd through the 4th centuries. I have created a 3D VRML walkthrough of the ancient bath. This interdisciplinary project utilizes the research of an archaeologist, architect, and art historian. Because the researchers live in different locations, it made sense to use the Internet as a research tool. When clicking on the numbers on the home page, you can see the process that I went through to model the Roman Bath. After seeing the images, the researchers were able to visualize their research, reply to questions, and re-evaluate their findings. VRML promises an accessible, highly visual, and interactive representation of difficult to see data, opening up new ways of presenting research. It is possible to walk within the bath by clicking on the Virtual Reconstruction link. When in the "Entrance view", click on the vase to see a map of the ruin. There are three places within the project that link to the existing excavated site. Links are also available to walk outside. The project runs best on Windows NT using Netscape. You must have the plug-ins for Cosmoplayer (VRML) and Quicktime (movie). Because the VRML plug-in doesn't work as well on a Mac, it is possible that you may only be able to view the images and movie from the project.

summary Since middle ‘90’s, the outbreak of 3d hardware acceleration devices for PC software, has facilitated a great evolvement in what is known as “Role Play Games” (RPG) – within the entertainment software industry. This development has produced such a phenomenon that surpassed all expectations. Through the game “engine” tools, virtual spaces can be achieved according to an editor’s criterium. Thus, a varied range of uses in different research fields are permitted. It is possible to build architectural simulations with high degree of realism an interactivity by means of ‘levels editors’ found in most of this games.

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.

source Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 404-409
summary The paper is an inclusive summary of research work on creating VR city models carried out over the last six years in the UK and Greece aiming to put into discussion the guidelines/ rules developed by the author. The paper is structured in three sections referring to the main stages in terms of either technical expertise and problem solving or conceptual structuring of information: creation of 3D city models, CAAD versus VR in digital city modelling and finally utilizing digital city models. The expected outcome of the work presented is the establishment of a body of knowledge that will facilitate the development of standards and guidelines for the creation of city models. There are obvious advantages in having a compatible set of city 3D models. On the other hand, there are different rules to be followed and issues to be solved, according to the scale of the model, level of detail that is needed—all these rules relate to the projected use of the model.

summary It has been designed and developed a system Web that has video in real time and an interactive product catalogue based on pseudo-three-dimensional models, that is to say, models that they pretend to be three-dimensional, but that in fact do not have geometry 3D properly in the memory, but of an appropriate composition according to the case of geometry 2D (image or any graph), that allows to see the model from several points of view and to consult additional information (weight, material, dimensions, etc.). They have been analyzed and proven the different formats from transmission of video and audio by Internet, studying all its parameters, until finding the optimal ones for this server. In comparison with the use of format VRML (Virtual Reality Modeling Language) used commonly to put models 3D in the Web, this system that we have devised presents like advantages the low time of load, the high precision of the views of the object and the low cost of maintenance of the Web. On the other hand, one does not have the infinity of views and facility of manipulation of the VRML.
