title	From Digital Heritage Documentation to 3D Virtual Reconstruction and Recreation for Heritage Promotion and Reinterpretation: The Case of the iHeritage Project
source	C+++: Computation, Culture, and Context – Proceedings of the 11th International Conference of the Arab Society for Computation in Architecture, Art and Design (ASCAAD), University of Petra, Amman, Jordan [Hybrid Conference] 7-9 November 2023, pp. 7-23.
summary	In the last two decades, the digital age Information and Communication Technologies (ICT) development and concerns combined with rapid technology have permitted the dissemination of different digital applications (including digital documentation, virtual reality (VR), augmented reality (AR), mixed reality (MR), digital gaming, and holograms etc.) oriented toward past, present and future communication using digital three-dimensional audio-visual content. Today, we must acknowledge that 3D virtual 3D reconstruction and recreation has become an established way to build, understand, reinterpret, and promote Cultural Heritage (CH). The virtual 3D reconstruction world and multimedia industry are often considered potential marketing channels for World Heritage Sites (WHS) and heritage tourism. 3D digital/virtual reconstruction merges and embodies subjectivity in one process, playing an attractive role in heritage tourism destinations and creating image experiences, providing the first enjoyable interpretation and information for most audiences. Based on the EU-funded iHERITAGE project ICT Mediterranean platform for the UNESCO CH, this paper attempts to examine some insights into constructing the optimistic image of heritage promotion and tourism in the context of CH as it flows through both physical and virtual spaces to give a glimpse of the future of virtual reconstruction. It illustrates the development of the concepts and practice, challenges and opportunities, advantages and disadvantages, and the negative and the positive sides of the related issues of only 3D digital reconstructions, and some issues concerning the ethics based on the International Chartres and Conventions mainly in the field of scientific visualisation, such as the London Charter (2009) and Seville Principles (2011). Finally, as a practical dimension, it presents some representative examples of 3D digital/virtual reconstruction of characteristic monuments of the WHS of Nabataean Petra in Jordan for the first time.

title	Potemkin Village, reloaded Visualization of Destroyed Synagogues within the Cityscape of Vienna
source	Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 53-58
summary	In our everyday life experience the use of projection media is ever present. The theme of this EAEA-conference seems at a first glance to be in favour of the projected view in a timeline, directed towards to the future. However, a re-reading of the thematic direction does suggest a relative consideration and viewing of both past and future. This contribution will elaborate on the virtual reconstruction of synagogues in the City of Vienna. On one hand, the use of fac_ade projections will be presented as a means to recreate a previous (non-existing) situation over a given time span in a manner which does not change the physical condition of the current building stock as such. Given that interior photography of the synagogues is very limited or non-existent, the possibility of recreating a set of endoscopic representations will be examined.

title	Navigating Complex Models in Collaborative Work for (Sustainably) Integrated Design
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 619-636.
summary	Increasingly intensive use of computational techniques such as parametric-associative modeling, algorithmic design, performance simulations and generative design in architecture, engineering and construction are leading to increasingly large and complex 3D building models which in turn require increasingly powerful techniques in order to be manipulated and interpreted effectively. Further complexities are of course due also to the multi-disciplinary nature of building projects, in which there can be significant variation and even conflict among the aims of architects, engineers and builders, as well as owners, occupants and other stakeholders in the process. Effective use of model information depends to a large extent on sense-making, which can in some ways be helped but also hindered by schemes for organizing the information contained. Common techniques such as layering, labeling (aka ‚Äòtagging‚Äô) and assignment of various other attributes to model objects have significant limitations ‚Äì especially those arising from general problems of language, ontology and standardization, as well as but distinct from issues of interoperability ‚Äì both with respect to locating the desired items in a 3D building model and also with respect to displaying the objects in informative ways which effectively assist collaborative design and decision-making. Sustainable design in particular is an area generally requiring a high level of inter-disciplinary collaboration to achieve highly integrated designs which make multiple use of the elements and systems incorporated (though integrated design may also be pursued without explicit aims of sustainability). The proposed paper describes ongoing research concerning alternatives to the currently common techniques for locating and displaying information in 3D building models in support of sense-making to promote collaborative and integrated design. These alternatives comprise on the one hand interactive geometric-content-based methods for search and classification of model objects ‚Äì as an alternative or complement to common assigned-attribute-based methods ‚Äì and on the other hand visual analytic techniques ‚Äì in contrast to existing, relatively static tabular and "physical" views ‚Äì which can help to increase the informativeness of the geometric data within the model, as well as the non-geometric data that is attached to geometric objects (e.g. as in the cases of BIM and various types of CAE performance simulations). Tests undertaken with architects and engineers in practice and academia to evaluate the proposed methods are also described. Finally conclusions are drawn regarding these methods‚Äô positive present performance and some of their shortcomings, as well as indicating directions for future research concerning the methods‚Äô refinement and extension to help 3D building models become more effective components of the design process than they are at present, both with respect to these models‚Äô present levels of complexity and especially with respect to their anticipated increasing complexity in future.

summary	In this paper we are to present a research, still in progress, whose main objective is the desire to develop and test an alternative method of surveying, representing and analyzing buildings that are part of a minor historical-artistic heritage. The instruments used and the proposed methodology want to give an alternative to other solutions such as 3D laser scanners and photogrammetry, which would be not only expensive, but also difficult to use in small and irregular spaces, typical of the old Italian villages. The case study that will be presented is Caporciano, a small medieval village in Abruzzo (a region at the centre of Italy), in the internal area of the region affected by a violent earth quake in 2009. This tragic event has put the spotlights on the problems and the fragility of these small villages, which represent an important local resource of cultural importance, and therefore must be preserved for the future generation. In order to properly act in these areas, it is necessary to thoroughly know the actions to be taken for its recovery or conservation, and the present methodology allows the creation of this knowledge made up of several drawings, both two-dimensional and three-dimensional.

title	Computational Fluid Dynamics for Urban Design: The Prospects for Greater Integration
source	International Journal of Architectural Computing vol. 9 - no. 1, 33-54
summary	Computational Fluid Dynamics (CFD) has always been used in the field of architecture, urban design and urban planning to understand the patterns of wind flow through the built environment. Its analysis is important to evaluate whether the natural ventilation through a site is adequate to mitigate heat and pollutant to achieve better human comfort in dense urban environments. However, given the complex operational requirements, the response to wind flow is not always done early enough to support planning and design. This paper seeks to illustrate how CFD analysis can aid planning and design of urban areas and investigates the workflow requirements, in the hope of making the CFD simulations more accessible to the practices and contribute to design decisions. It also looks at the present technological advancements and future prospects to assess the scenarios where emerging technologies can make CFD simulation more readily available with affordable and even mobile hardware installations.

title	Spatial Experience in Real & Virtual Environment as an Urban Design Tool
source	Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 59-64
summary	The innovations of information technologies and the new possibilities of multimedia exploitation in the realm of architectural design and education are supporting the development of image communication methods on the basis of interactivity. The creative process of searching and decision-making in the urban design studio of our Faculty is supported by spatial modeling methods. The draft is sketched in modeling material on a working model. From the didactic point of view, relevant are mainly those phases, in which is possible, in the imaginative way, to support the searching and decision making process with the aim to test, compare and continuously evaluate the fulfillment of the hypothetic intentions of the solution responsibilities. The model becomes an interactive medium of cooperation between teacher and the working group of students. From the view of design crystallization, the dominant phases, in the creative process, are examining, verification, and simulation. The alternatives of material-compositional content and the spatial performance charts of modeled physical structure are verifying and the visual experience of the anticipated urban environment is simulated by the author, but also through the future client’s eyes. The alternation of the composition’s spatial configurations is generally appreciated by the static visual verification in the endoscopic horizon like the architectural spatial studies. The effective method of the progress generates a creative atmosphere for the generative thinking and design. The laboratory simulation of spatial experiences and their evaluation is performed following the perception psychology relations. The simulation of digestion of the new spatial reality intervenes the customer’s identification and guides to subjective approaches towards the quality and complexity of the formed environment. The simulation is performed in motion in order to be able to anticipate the dynamic continuity of subjective spatial imagination. The induced atmosphere will direct the evaluational attitudes of authors on comparison and selection of the successful alternatives. In our fee, we will present the demonstrations of selected static and dynamic notations of image sequences prepared in our laboratory. The presentations have been created in order to analyze, verify and offer imaginative support to creative findings in result of fulfilling the studio design tasks in the educational process. The main one is the design of urban spatial structures. The laboratory methodology is in the first place oriented on the analogue-digital procedures of "endoscope" model simulation. At the same time it also explores and looks for new unconventional forms of visual communication or archiving as imagination support to specialist and laymen participants in creative, valorization and approval processes.

title	A context immersion of mixed reality at a new stage
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 199-208
doi	https://doi.org/10.52842/conf.caadria.2011.199
summary	This paper presents a novel approach to the potential of mixed reality embodied in smart phones and ubiquitous environments. We analyzed the related works to the concept of context and mobile computing and then investigated into leading companies by interviewing senior manages of the mixed reality (MR) projects in Korea. As a result, the concept of context immersion is proposed for describing the various context relationships among the real locations, objects and persons. By considering the MR environments as a converged world, this paper characterizes the context immersion as the combination of the time & location-based, object-based and user-based contexts. Through the context immersion, users can be connected to the real life, not limited to the imagery world, thus experiencing strong immersion in the MR environments. At the end, we present the development direction for the future with a focus on the MR contents rather than the technical aspects.

summary	In this paper we compare visual and textual programming languages for generative design. We argue that, in the past, this comparison has been flawed and that it is now time to reconsider the potential of the textual programming paradigm but using modern programming languages and development environments specifically targeted to the generative design domain. We present VisualScheme as a prime example of such language and we compare it with the most used visual programming language in the generative design field.

summary	A non destructive testing process is becoming a technical need, thousands of buildings and huge urban areas will have to be adapted to restrictive energy-saving standards and sustainability criteria. Analysis and diagnostics are required on a massive scale. Building Information Modeling seems to be the adequate environment to assemble huge amounts of data. At this moment both hardware and software technologies are performing moderately well separately. The challenge is to connect them and in the long run automate data collection and conversion to a unified model that could be maintained during the programmed building life cycle. The aim of this research is to discuss the challenge of NDT hardware and BIM software systems integration and define the basic steps for the best practices to undertake it in a fast and accurate manner as well as to define the present and future connections to be developed. A 3 phase joint research project is proposed here and basic needs are analysed. Many lessons have been learned from field work, data translation and data incompatibilities with many shortcomings being detected.

doi	https://doi.org/10.52842/conf.acadia.2011.260
summary	In this paper, we will explore the potentials of low-cost portable immersive environments that combine textile structures, gesture-based interfaces and multiple projections. Our aim is to develop affordable, easy to set up, portable and inviting immersive spaces that can serve as an interface between a web-based geographic virtual environment, experts and lay people. In this context, after the introduction, we will review a variety of methods, conceptual tools and materials related to textile tectonics and techniques which can be individually used or combined for the development and construction of portable immersive spaces. In the next section, we will discuss the opportunities and challenges of using a low-cost gesture-based interface (Kinect) to support “touchless” interactions. Consequently, we will present the design alternatives of low-cost portable immersive spaces that we have synthesized from our background studies. This will be followed by the observations and findings from our prototype development, implementation and preliminary testing processes. In conclusion, we will discuss our conclusions and recommendations regarding the future development of low-cost portable immersive spaces.

title	Interpreting Digital Heritage: A Conceptual Model with End-Users' Perspective
source	International Journal of Architectural Computing vol. 9 - no. 1, 99-114
summary	Present virtual heritage projects are mostly focused either on ‘process’ or ‘product’ but rarely consider ‘users’ (end-users' perception of the content) with project contents predominantly developed with an ‘ocular-centric’ tendency. There is no significant interpretation method or principle for interpreting digital heritage like other disciplines such as archaeology. This paper argues that, for better interpretation and experience of a digital heritage site, a comprehensive interpretation method is required, which should address end-users with various background, overcome the linearity in narrative level and subjectiveness in content creation. This paper also argues that instead of predetermined instructional sequences or descriptive interpretation, the interaction setting can be participatory and contributive, where the end-users and environment may engage in ‘dialogic-interaction’. In terms of methodology, ‘Interpretation’ is first conceptualized by assimilating definitions from various heritage scholars and interpretation organizations. Notions of interpretation-practice and level of interaction are identified from reviewing some online digital heritage projects. By identifying weaknesses, this paper finally proposes a conceptual model for developing a comprehensive interpretation method for future digital heritage projects.

summary	Driven by advances in building and information technology and accelerated by the tumultuous period of global economic restructuring that commenced in 2008, architecture and interior design practice is today confronted with the necessity of fundamental change. According to the “Building Futures” group at the Royal Institute of British Architects and US-based “Design Futures Council,” both of which this past year published studies on this very topic, a great deal depends on what happens in China and other emerging markets, where many European and US firms now have offices. And that is not only because these are the most vibrant markets for architecture and design services, but also because the demands placed on practitioners in these markets are fundamentally changing the way buildings are designed and delivered, at home and abroad. Both studies suggest that all sectors of the A/E/C industry will face increasingly fierce competition that will, of necessity, force practices large and small to compete less on cost and more on value. In the very near future buildings and their interiors will be valued almost entirely based on performance—economic, cultural, environmental—and only those firms able to create these and other forms of added value will survive. Disruptive technologies like building information modeling and integrated product delivery will enable all firms, even those competing solely on the basis of cost, to design better buildings and deliver them more efficiently. But in such a fiercely competitive global marketplace, efficiency alone will not be enough to guarantee market viability. The real differentiator will instead be design.

title	La cámara en la animación de arquitectura. Reconsiderando “la mirada” y el régimen de mostración en el cine [The Camera in Architectural Animation. Reconsidering “The Gaze” and The Registration Regime in the Cinema]
source	SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 432-435
summary	Even though inspired by cinema, architecture animations often oversimplify filmic space, and conflate two distinct concepts: gaze, and vision. Such misinterpretation leads to overuse camera movement to present spaces as if the change of point of view would lead to communicate lived space. This article introduces such discussion in the context of the tableau vivant, a living picture, explores the use of the shot sequence and the use of non-narrative scenes.

title	Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 181-200.
summary	The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

summary	Architectural contexts present both resources and restrictions from local spatial environment, such as factors of sunlight, landscape, line of sight, terrain and etc. They play important roles in architectural design. Following the traditional methods, it takes the architects lots of time to analyse the relative relationships. This paper takes terrain and sunlight into consideration to illustrate how to employ generative methods at the early stage of architectural design.

title	Using 3D Design Software, BIM and Game Engines for Architectural Historical Reconstruction
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 493-509.
summary	The use of digital tools has become a tremendous aid in the creation of digital, historical reconstructions of architectural projects. Regular visualization techniques have been used for quite some time and they still pose interesting approaches, such as following cinematic techniques [1]. While common visualizations focus on pre-rendered graphics, it is possible to apply Game Engines [2] for real-time architectural visualization, as witnessed by [3] and [4]. In the course of our teaching and research efforts, we have collected experience with several visualization and modeling techniques, including the use of gaming engines. While the modeling of qualitative geometry for use in regular visualization already poses an elaborate effort, the preparation of models for different uses is often not trivial. Most modeling systems only support the creation of models for a single amount of detail, whereas an optimized model for a real-time system will have fairly different constraints when compared to non-real-time models for photorealistic rendering and animation. The use of parametric methods is one usable approach to tackle this complexity, as illustrated in [4]. One of the major advantages of using parametric approaches lies precisely in the possibility of using a single model to generate different geometry with control over the amount of detail. We explicitly tackle this in a Building Information Modeling (BIM) context, as to support much more than purely 3D geometry and visualization purposes. An integrated approach allows the same model to be used for technical drawings in 2D and an optimized 3D model in varying levels of detail for different visualization purposes. However, while most Building Information Modeling applications are targeted to current architectural practice, they seldom provide sufficient content for the recreation of historical models. This thus requires an extensive library of parametric, custom objects to be used and re-used for historically accurate models, which can serve multiple purposes. Finally, the approach towards the historical resources also poses interpretation problems, which we tackled using a reasonably straightforward set up of an information database, collecting facts and accuracies. This helps in the visualization of color-coded 3D models, depicting the accuracy of the model, which is a valuable graphical approach to discuss and communicate information about the historical study in an appealing format. This article will present the results of different reconstruction case studies, using a variety of design applications and discuss the inherent complexity and limitations in the process of translating an active, evolving model into an environment suitable for use in a real-time system. Especially workflow issues are identified, as the translation of the model into the game engine should be repeated several times, when the model is further refined and adapted. This used to involve a large amount of repetitive work, but the current crop of game engines have much better approaches to manage the updating of the geometry.

summary	This article presents a study on the representation of cities in the era of digital culture and aims to show how the phenomenon of self-production is present in the websites studied. At the end, we conclude that cities (through city marketing), local government (through advertising and through the creation of an identity) and citizens (through selfbranding), they create a rhetorical itself and constitute itself as brands. Therefore, we conclude that cybercities has been more an extended space of consumption and production of cities, municipalities and citizens.

title	Diseño digital y manufactura artesanal, ejemplos de diseño paramétrico en Chile [Digital design and handcrafted manufacturing, examples of parametric design in Chile]
source	SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 60-63
summary	The present article tracks and attempts to portray the current state of the art, in relation to the application of parametric or algorithmic design in Chilean architecture and design production. These technologies have emerged in the last decades and have become increasingly popular in the international arena. Through the presentation of examples made at different scales, the processes of digital and traditional manufacture used in each work of art are revealed. The difficulties, advantages and virtues of these tools are discussed and addressed from a local educational and professional perspective.

title	Parametric Form-Based Codes: Incorporation of land-use regulations into Building Information Models
source	Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
doi	https://doi.org/10.52842/conf.acadia.2011.x.l7j
summary	This project describes investigations into whether parametric modeling using a Building Information Modeling (BIM) platform can represent the provisions and constraints of Form-Based Codes (FBCs). BIM software environments couple 3D modeling with parametric form generation and rich semantics. Further capabilities of an Application Programming Interface that supports Object-Oriented Programming (OOP) results in a very powerful environment for expressing planning and design concepts. While these capabilities were developed under the intention of supporting building design, we hypothesize that they can support planning rules and regulations that are found in FBCs. If our approach is successful, future planning departments will be able to provide architects and urban designers with a FBC that is implemented as a BIM software toolkit, better integrating the planning phase of a project into the building design phase.

title	Towards a Morphogenetic Control of Free-Form Surfaces for Designers
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 165-180.
summary	The present paper discusses a novel computational design strategy for approximating architectural free form geometry with discrete planar elements by using morphogenetic patterns. We report on an ongoing research project [1], which is focused on the design of flat ornamental tessellations by using computational geometry for the discretization of curved forms rather than manufacturing curvy elements, which typically increase cost. The significance of our approach lies in the fact that it allows the designer to progressively embrace the constructive constraints and their esthetic potential already in the design stage and to follow them through to actual fabrication.
