title	Appropriations and Extensions of Cultural Spaces in VR and the Metaverse
source	Herrera, PC, Dreifuss-Serrano, C, Gómez, P, Arris-Calderon, LF, Critical Appropriations - Proceedings of the XXVI Conference of the Iberoamerican Society of Digital Graphics (SIGraDi 2022), Universidad Peruana de Ciencias Aplicadas, Lima, 7-11 November 2022 , pp. 727–738
summary	Digital virtual reality (VR) and the metaverse provide opportunities for the creation of cultural extensions that define our contemporary society. This has been the practice for millennia – using different technologies and media; humans have always attempted to convey experience through representational forms. The paper puts forward an initial theoretical examination of metaverse using theories on perception and subjectivity in psychology and philosophy and the implications of these in architecture and space creation, both physical and digital. It considers historical VR spaces to better understand the influence of culture and applies this to the contemporary social VR spheres. Though they offer novel opportunities, digital virtual realities and immersive spaces of today are no different than the lineage of spaces and representations that strove to do this throughout history (Grau, 2003). Using different mediums, they each provide an extension of culture that reflects society and becomes a record of their times and ideals.

summary	Augmented Reality (AR), the layering of reality and virtuality, can be used as a tool in architecture in model scale as well as in 1:1 scale on site. By combining real architecture models with virtual representations like e.g. wind simulation an intensive understanding for impacts can be observed. Coupling AR with further virtual environments (AR and Virtual Reality) in one scenario makes AR a tangible interface for VR and on the other hand supports the group discussion of distributed teams.

summary	The conference logo is a bird’s eye view of spiral stairs that join and separate – an homage to the famous double spiral staircase in Graz, a tourist attraction of this city and a must-see for any architecturally minded visitor. Carved out of limestone, the medieval construction of the original is a daring feat of masonry as well as a symbolic gesture. The design speaks of separation and reconciliation: The paths of two people that climb the double spiral stairs separate and then meet again at each platform. The relationship between architectural design and the growing digital repertoire of tools and possibilities seems to undergo similar cycles of attraction and rejection: enthusiasm about digital innovations – whether in Virtual Reality, Augmented Reality, Energy Design, Robotic Fabrication, the many Dimensions of BIM or, as right now, in AI and Machine Learning – is typically followed by a certain disillusionment and a realization that the promises were somewhat overblown. But a turn away from these digital innovations can only be temporary. In our call for papers we refer to the first and second ‘digital turns’, a term Mario Carpo coined. Yes, it’s a bit of a pun, but you could indeed see these digital turns in our logo as well. Carpo would probably agree that design and the digital have become inseparably intertwined. While they may be circling in different directions, an innovative rejoinder is always just around the corner. The theme of the conference asked participants to re-consider the relationship between Design and the Digital. The notion of a cycle is already present in the syllable “re”. Indeed, 20 years earlier, in 2003, we held an ECAADE conference in Graz simply under the title “Digital Design” and our re-using – or is it re-cycling? – the theme can be seen as the completion of one of those cycles described above: One level up, we meet again, we’ve come full circle. The question of the relationship between Design and the Digital is still in flux, still worthy of renewed consideration. There is a historical notion implicit in the theme. To reconsider something, one needs to take a step back, to look into the past as well as into the future. Indeed, at this conference we wanted to take a longer view, something not done often enough in the fast-paced world of digital technology. Carefully considering one’s past can be a source of inspiration. In fact, the double spiral stair that inspired our conference logo also inspired many architects through the ages. Konrad Wachsmann, for example, is said to have come up with his famous Grapevine assembly system based on this double spiral stair and its intricate joinery. More recently, Rem Koolhaas deemed the double spiral staircase in Graz important enough to include a detailed model of it in his “elements of architecture” exhibition at the Venice Biennale in 2014. Our interpretation of the stair is a typically digital one, you might say. First of all: it’s a rendering of a virtual model; it only exists inside a computer. Secondly, this virtual model isn’t true to the original. Instead, it does what the digital has made so easy to do: it exaggerates. Where the original has just two spiral stairs that separate and join, our model consists of countless stairs that are joined in this way. We see only a part of the model, but the stairs appear to continue in all directions. The implication is of an endless field of spiral stairs. As the 3D model was generated with a parametric script, it would be very easy to change all parameters of it – including the number of stairs that make it up. Everyone at this conference is familiar with the concept of parametric design: it makes generating models of seemingly endless amounts of connected spiral stairs really easy. Although, of course, if we’re too literal about the term ‘endless’, generating our stair model will eventually crash even the most advanced computers. We know that, too. – That's another truth about the Digital: it makes a promise of infinity, which, in the end, it can’t keep. And even if it could: what’s the point of just adding more of the same: more variations, more options, more possible ways to get lost? Doesn’t the original double spiral staircase contain all those derivatives already? Don’t we know that ‘more’ isn’t necessarily better? In the original double spiral stair the happy end is guaranteed: the lovers’ paths meet at the top as well as when they exit the building. Therefore, the stair is also colloquially known as the Busserlstiege (the kissing stair) or the Versöhnungsstiege (reconciliation stair). In our digitally enhanced version, this outcome is no longer clear: we can choose between multiple directions at each level and we risk losing sight of the one we were with. This is also emblematic of our field of research. eCAADe was founded to promote “good practice and sharing information in relation to the use of computers in research and education in architecture and related professions” (see ecaade.org). That may have seemed a straightforward proposition forty years ago, when the association was founded. A look at the breadth and depth of research topics presented and discussed at this conference (and as a consequence in this book, for which you’re reading the editorial) shows how the field has developed over these forty years. There are sessions on Digital Design Education, on Digital Fabrication, on Virtual Reality, on Virtual Heritage, on Generative Design and Machine Learning, on Digital Cities, on Simulation and Digital Twins, on BIM, on Sustainability, on Circular Design, on Design Theory and on Digital Design Experimentations. We hope you will find what you’re looking for in this book and at the conference – and maybe even more than that: surprising turns and happy encounters between Design and the Digital.

summary	DaimlerChrysler as a worldwide operating company is continuously maintaining and developing their brand architecture for the points of sale. It is one of the strategic decisions to have a 'Brand Architecture Center' at the company headquarters in Stuttgart to develop the brand architecture and engage local architects to adopt it to the local context. As a major step, a new generation of autohauses is currently developed. Many aspects have to be taken care of in this process, therefore a great number of specialists have to be involved. They are supported by Virtual Reality (VR) and Augmented Reality (AR). To integrate VR/AR into the architectural process, necessary architectural interactions have been integrated into the software

title	Immersion, Interaction, and Collaboration In Architectural Design Using Gaming Engines
doi	https://doi.org/10.52842/conf.caadria.2003.721
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. 721-738
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,"

title	DESIGN AGENTS IN 3D VIRTUALWORLDS
source	IJCAI03 Workshop on Cognitive Modeling of Agents and Multi-Agent Interaction, R Sun (ed), IJCAI, Acapulco, pp 92-100.
summary	Design agents are rational agents that monitor and modify elements of a designed environment. Special characteristics of design agents include the ability to reason about patterns and concepts, and the ability to act autonomously in modifying or changing the design to achieve their own goals. 3D Virtual Worlds are multi-user distributed systems that provide a designed environment and a closed world environment for studying design agents in a multiagent system. We present a model for a design agent reasoning process and a model for constructing a memory of the agent’s knowledge and interaction with a virtual world. The reasoning process includes sensation, perception, conception, hypothesizing, and planning a sequence of actions. Each agent has a constructed memory: a dynamic and changing view of the designed world that is determined by the agents sense data and reasoning. The agents construct and maintain a representation of the relevant objects in the world using a Function- Behavior-Structure formalism in order to reason about the intended and actual functions of the designed objects in the world. We have implemented this agent model by extending the Active Worlds platform so that each object in the 3D world can have agency. We illustrate the model with a door agent and a multi-agent room that reason about the use of the 3D world.

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.

source	SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary	A method is proposed for architectural construction of virtual spaces by using structures of mnemotechniques. Defined as belonging to the mind, it is proposed to conceive the virtual space through architectural methods by adding the use of Mnemonics, which is the art and technique of developing and strengthening the memory. The memorization process itself becomes central in the process of constructing the virtual context. Introducing examples in history and recent art applications in virtual reality, this paper proposes the introduction of mnemotechniques for the architectural spatial structuring of the virtual space.

title	Sustainability: real and/or virtual?
source	Automation in Construction, 12(6), November 2003, pp. 641–648
summary	The starting point for this paper is the identification of the four necessary and sufficient conditions which a building should exhibit to be judged to be sustainable; fitness-for-purpose, cost effectiveness, environmental friendliness, and cultural significance. The contribution which the current generation of CAD tools is making to the complex human activity of designing sustainable buildings is then discussed under the headings of widening the search for solutions, integrating the decision-making process, improving design insights, differentiating objective/subjective issues and photorealistic visualization. The paper then describes developments in the next generation of IT tools, based on virtual reality, which will allow multiple designers, working in distributed locations and on different computer platforms, to design from within the virtual world.

title	Digital Design - Research and Practice
source	Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1 / Tainan (Taiwan) 13–15 October 2003, 464 p.
summary	The use of computers in the design of the built environment has reached a watershed. From peripheral devices in the design process, they have in recent years come to take centre stage. An illustration is immediately at hand. Just as the entries to the competition for the Chicago Tribune Tower in 1922 defined the state-of-the-art at the beginning of the twentieth century, we have a similar marker at the end of the century, the competition in 2002 to replace the World Trade Centre towers in Lower Manhattan offered us a range of architectural solutions that exemplified the state-of-the-art eighty years later, setting forth not only architectural statements but also illustrating clearly the importance of computers in the design of the built environment. In these entries of 2002, we can see that computers have not only become essential to the communication of design but in the investigation and generation of structure, form and composition. The papers in this book are the current state-of-the-art in computer-aided design as it stands in 2003. It is the tenth in a series sponsored by the CAAD Futures Foundation, compiled from papers presented at the biennial CAAD Futures Conferences. As a series, the publications have charted the steady progress in developing the theoretical and practical foundations for applications in design practice. This volume continues in that tradition; thus, this book is entitled Digital Design: Research and Practice. The papers are grouped into three major categories, reflecting thrusts of research and practice, namely: Data and information: its organisation, handling and access, including agents; Virtual worlds: their creation, application and interfaces; and Analysis and creation of form and fabric. The editors received 121 abstracts after the initial call for contributions. From these, 61 abstracts were selected for development into complete papers for further review. From these submissions, 39 papers were chosen for inclusion in this publication. These papers show that the field has evolved from theoretical and development concerns to questions of practice in the decade during which this conference has showcased leading work. Questions of theoretical nature remain as the boundaries of our field expand. As design projects have grasped the potentials of computer-aided design, so have they challenged the capabilities of the tools. Papers here address questions in geometric representation and manipulation (Chiu and Chiu; Kocaturk, Veltkamp and Tuncer), topics that may have been considered to be solved. As design practice becomes increasingly knowledge based, better ways of managing, manipulating and accessing the complex wealth of design information becomes more pressing, demanding continuing research in issues such as modelling (Yang; Wang; Zreik et al), data retrieval and querying (Hwang and Choi; Stouffs and Cumming; Zreik, Stouffs, Tuncer, Ozsariyildiz and Beheshti), new modes of perceiving data (Segers; Tan). Tools are needed to manage, mine and create information for creative work, such as agents (Liew and Gero; Smith; Caneparo and Robiglio; Ding et al) or to support design processes (Smith; Chase). Systems for the support and development of designs continue (Gero; Achten and Jessurun). As progress is made on some fronts, such as user interfaces, attention is again turned to previously research areas such as lighting (Jung, Gross and Do; Ng et al; Wittkopf; Chevier; Glaser, Do and Tai) or services (Garcia; Chen and Lin). In recent years the growth of connectivity has led to a rapid growth in collaborative experience and understanding of the opportunities and issues continues to mature (Jabi; Dave; Zamenopoulos and Alexiou). Increasing interest is given to implications in practice and education (Dave; Oxman; Caneparo, Grassi and Giretti). Topics new to this conference are in the area of design to production or manufacture (Fischer, Burry and Frazer; Shih). Three additional invited papers (Rekimoto; Liu; Kalay) provide clear indication that there is still room to develop new spatial concepts and computer augmented environments for design. In conclusion, we note that these papers represent a good record of the current state of the evolving research in the field of digital design.

summary	As a result of growing activity in the field of renovation and building within existing built contexts, modern digital tools and methods are increasingly in demand. Support of the planning process means: the step-by-step capture of building-relevant information, a rule and parameter-based development of solutions and the combination of traditional and automated methods and technologies used for model creation (building surveying) and model transformation (planning). This article discusses general requirements and the results from our own research and development as well as illustrating how building surveying can already contribute to the planning process more effectively using currently available tools.

summary	The course Alternatives of Design is part of an integral viewpoint that aims to prepare architects from the Master Studies Department in Computing in Architecture (LUZ), in two ways: first, by expanding their perspective about potentialities of using new digital technologies in architecture, and second, by qualifying them to apply this acquired theoretical knowledge in their professional environment. The objectives of this paper are to describe the program of this course and to show products (2003), from the introductory to the final presentation of Virtual Museums of Interactive Sculptures, orientated and supervised both at site and at a distance through the Internet. As a result of this experience, a sample was obtained of virtual museums. design and modelling that illustrates what could be understood as virtual architecture with high degree of interaction, looking for the evolution, motivation and teamwork to incorporate virtual reality non-inmersive technologies in this new architectonic approach.

summary	The aim of this study was to examine the feasibility of virtual reality (VR) technology for use by persons with dementia (PWD). Data were obtained directly from six PWD regarding their experiences with a virtual environment (VE) of a large outdoor park. A user-centered method was developed to assess: (a) presence; (b) user inputs; (c) display quality; (d) simulation fidelity; and (e) overall system usability. The extent to which PWD could perform four functional activities in the VE was also investigated (e.g., mailing a letter). In addition, physical and psychological well-being of PWD while interacting with the VE was assessed objectively by recording heart rate during the VR sessions and subjectively with discrete questionnaire items and real-time prompts. Symptom profiles associated with simulator sickness were assessed with an adapted version of the Simulator Sickness Questionnaire. The study found that PWD to some extent experienced presence; perceived that objects were realistic and moved naturally; generally felt in control of the interaction; and demonstrated little difficulty using a joystick for navigation. The study also demonstrated that VR is an appropriate medium for assessing functional behavior within the context of an ecologically valid VE. PWD did not experience any significant increase in symptoms associated with simulator sickness, or detriments to their psychological and physical well-being. These findings demonstrated that it is feasible to work in VEs with PWD.

summary	While it is well known that the built environment influences our emotional state, it is often difficult to attribute these experiences to particular properties. In fact, a systematic investigation of the relation between physical structure and emotional experience of architecture has not yet been done. Now virtual reality simulations facilitate a completely controlled variation of spatial properties and thus allow to empirically evaluate architectural hypothesises. The aim of the presented study was to investigate which factors from a component-based description of rooms significantly correlate with cardinal dimensions of experience. In a perceptual experiment experiental qualities of 16 virtual vacant rectangular interiors were rated in eight principal categories by 16 participants using the semantic differential scaling technique. The scenes were generated by a custom made graphics tool that also automatically generated the component-based scene descriptions. The data analysis revealed several interesting correlations between scene features and rated experience: For example, a preference for ratios near to the golden section could be observed for spatial proportions, which are not directly perceivable. Altogether, a set of five independent factors (openness, two room proportions, room area and balustradeheight) appeared to be effective for widely describing the observed variance of the averaged attributed experiental qualities. Our combination of realistic virtual reality simulations and psychophysical data raising methods proved to be effective for basic architectural research. It allowed us to demonstrate quantitative relations between physical properties from a component-based description of architectural space and its emotional experience.

title	Interaction of the design methods and the contemporary computer techniques
source	Faculty of Architecture, Warsaw University of Technology
summary	The thesis researches a bilateral relations between computer techniques and methods of architectural design. It represents a holistic attitude because of a multithread analysis in the field of the theory of design, a new hard- and software used by architects, and a design practice. Thesis: Contemporary computer science development at the end of the twentieth century pushed architects to use hard- and software as tools, which became an active support (more than just CAAD). It enabled to widen the scope of a form-properties research and a generation of solutions impossible to achieve before, by using traditional methods and tools. This situation leads to new, unpredictable possibilities of architectural research and design. Objectives: 1. Definition of the latest trends in computer technologies applied in architectural offices. 2. Presentation of some practical consequencies of application of those technologies in design and construction. 3. Separation of new design methods caused by use of digital tools. 4. A simplified taxonomy of the methods above, with characteristic features. 5. A research in practical application of digital tools in Polish and foreign offices, as well as at the WUT Faculty of Architecture. The subject of the work: The thesis constitutes of five chapters. The first chapter is an introduction, where the range of work is presented in the context of place, time and the research made. The following chapters research three aspects of CAAD: (1) hardware and software, (2) new definition of architecture, which is a result of application of the digital tools, (3) practical problems connected with the use of computer techniques. The second chapter describes the new technologies in use –Virtual Reality (incl. VRD, CAVE’s, Data Gloves, motion-capture), Rapid prototyping (incl. holographic printers, 3D scanners, routers, milling-machines), new types of interfaces (e.g. xWorlds, InfoSpace, Flock of birds), etc. The third chapter is a theoretical one. It presents three types of changes in design methods, which can be classified, judging by results, in architecture of: (a) in-formation (b) de-formation and (c) cyberspace. All the mentioned applications of a digital technology cause redefinition of the range of the architects’ profession. The fourth chapter is concentrated on the application and utilization of technology. It is a detailed analysis of chosen buildings (characteristic examples) and design methods used by some avant-garde and well-known practitioners and visioners of architecture (Eisenman, Gehry, Spuybroek, etc.). It also presents statistics, where the influence of digital tools on the way of working (efficiency, productivity, use of tools) is expressed numerically. A synthesis summarizes the relation between architects and the new digital tools in some aspects: hard- and software, social changes, ergonomics, methodics, linguistic/symbolic and architectural. The mentioned ranges of interaction constitute the proof of the thesis.

summary	During the event Cultural Market Days on 23 and 24 August 2003 at Noerrebro Park in Copenhagen, visitors could also enter the marketplace from their home via the Internet, as a digital 3D model had been constructed that showed the marketplace with all its information booths and activities. This virtual marketplace functioned as an extension of the urban space, allowing you to take part in the flow of information, activities and experiences that were offered in the marketplace. And this just by a click on the Internet address: http://www.e-kvarter.dk. Furthermore at certain times of the day you could chat with people from some of the many working groups of the urban regeneration project in Noerrebro. The digital 3D model is similar to the marketplace, but it creates its own universe in the green surroundings of Noerrebro Park. And now, when the Cultural Market Days are finished and the booths and people have gone, the Electronic Marketplace still remains on the Internet, with a potential for developing a new public space for information, dialogue and cooperation between the actors of the urban regeneration project. This paper presents the results of a 3-year research project, The Electronic Neighbourhood (2000-2004). Researchers have developed and tested a digital model of the urban area and other digital tools for supporting the dialogue and cooperation between professionals and citizens in an urban regeneration project in Copenhagen. The Danish Agency for Enterprise and Housing, the Ministry for Refugees, Immigration and Integration and Copenhagen Municipality have financed the research, which is planned to be published 2004. The results can also be followed on the Internet www.e-kvarter.dk.

title	MetropoGIS: A City Modeling System
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	We report on a new system to generate photo-realistic 3D models of real cities. So far, we focus on the accurate geometric andradiometric modeling of man-made structures. The modeling process starts with a 3D block model obtained from aerial images, aerial laser scans or GIS data. This block model is further augmented with geo-referenced terrestrial images of the facades. Theterrestrial images are either captured using a mobile multi-sensor-platform or an off-the-shelf digital camera. The relative orientationof terrestrial images is calculated automatically and fitted towards the 3D block model with minimized human input using vanishingpoints. 2D image features like lines are extracted from the images and used to model 3D lines using line matching techniques. Theextraction of dense 3D point clouds on the facades is based on a hierarchical point matching strategy over multiple oriented images.Facades are found by robust fitting of plane hypotheses through these 3D line and point clouds. The introduced city modeling systemdelivers a fully 3D geographic information data set and is called MetropoGIS.

summary	In Taiwan, it is a common phenomenon that landscape, urban spaces, and buildings are not considered as a whole by governments at all levels and private clients. More terribly, the government has never proposed any urban statement for the future. The Minister strongly therefore proposes this statement: 2050 vision Taiwan, aim to design the public spaces for the life of Taiwan in the year 2050. The Council for Culture Affairs plans to spend two years to cover 100 locations and invite 20 design teams to provide new vision of the places. Our design team, AleppoZONE first conducts the initial stage of this project that includes three areas of Taiwan: Taipei as the capital of Taiwan is expected to become a better place reflecting new and old space combination. Hsinchu is planned to explore the prototype for a digital city where digital technology is wellinstalled in the city plaza and public buildings. In the island of Pen-Hu, the ecology and high-tech transportation are equally considered to shape Pen-Hu as an island with nature. In the process, design team successfully synthesizes digital models and dynamic films into virtual and physical coexisting environmental animations by using multiple digital media in realizing the 2050 vision cities. The aim of this research is to give a throughout introduction of this project.

title	Space, Place and Digital Media:Towards a Better Simulation of a City that has now Disappeared
source	International Journal of Architectural Computing vol. 1 - no. 1
summary	Digital media enable researchers and designers to derive better informed processes in solving problems of historical architectural restoration and virtual archaeology. However, recently insufficiencies have been found in the main technologies often applied in such techniques, such as 3D modeling, high-quality rendering and animation. Given these problems, this paper attempts to explore a digital reconstruction procedure for historical architecture and cities using 3D scanning, Virtual Reality cave technology and motion capture technology. This case study is based on a collaborative project in conjunction with the National Palace Museum, Taiwan, and the China Times, Taiwan.The five steps involved in this project include data collection and analysis, three-dimensional digital inferences, digital reconstruction of static and moving models, scenario dynamics (by integrating the two kinds of models), and visual-spatial immersion using a VR-cave representation. Finally, a preliminary digital reconstruction procedure is presented.
