title	Development of a New CIS/2 (CIMsteel Integration Standards) Model Viewer
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 83-92
summary	The purpose of developing a CIS/2 data viewer is not only to facilitate software developers to visualise exported CIS/2 files and to validate geometric correctness, but also to provide non-3D-model-based CIS/2 applications with an interface for geometric visualisation and complex 3D-spatial computation. The GT CIS/2 Model viewer enhances the functionality of existing data viewers and proposes a new visualisation method for a CIS/2 model.

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	An architectural framework within a spatially immersive real-time environment for advanced communication and collaboration
doi	https://doi.org/10.52842/conf.ecaade.2003.037
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 37-43
summary	In this paper we present a framework for use in the blue-c, a collaborative telepresence environment. We implemented the framework on top of the blue-c API to enable new ways of designing digital 3D spaces in an immersive way. The framework will be used to support designers in creating spatial scenarios within CAVETM – like environments. It concentrates on the integration aspect of different media and data types. Architectural knowledge and information technology is combined to introduce a new approach for designing virtual environments.

title	An Immersive Virtual Reality System for Interior and Lighting Design
doi	https://doi.org/10.52842/conf.caadria.2003.593
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. 593-596
summary	We are developing an immersive virtual reality system for interior and lighting design where, inside a CAVE(r), one can change at will the color, texture and finishing of all elements in the simulated environment (walls, floor, furniture and decoration) as well as position, type, color and intensity of all light sources. Although the rendering algorithm used in the system is the ray tracing, preliminary results show we are able to achieve almost real time performance. The system is intended to both help architects to better communicate their design ideas to clients through an advanced visualization tool and also speed up the interior and lighting design processes.

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.

title	Interaction, Agency and Artefacts
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 249-258
summary	This paper argues (i) that understanding of a place (especially in heritage environments) requires a level of cultural engagement and (ii) that virtual environments, in their typical current form, fail to provide such engagement. A proposed solution to the issue of cultural presence is to apply the interactive mechanisms commonly used in computer games (social agents, levels of interaction constraint, and task-based manipulation of artefacts) to virtual heritage environments. The hypothesis is that the resulting environment will allow for greater engagement and a more culturally immersive learning environment. Virtual environments also often lack techniques for evaluating the extent to which their design goals are achieved. A proposed secondary outcome is that designers and researchers of virtual environment can also use the above interactive mechanisms for the evaluation of user engagement without simultaneously interrupting the user’s feeling of engagement.

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	Describing design as a sequence of steps cannot convey the complexity of social interactions that it embodies. Design is not merely a process, but a co-evolution of efforts and events in various places and times—both synchronous and asynchronous. Designers share their values, effort and expertise within design settings via artifacts that further the design process. Increasingly, these design settings in academia, research, and professional practice combine physical and virtual modalities such as immersion, projection, and a range of interaction technologies. Peter Anders has described such spaces as cybrids: hybrids that integrate virtual and physical space. In these settings, designers use overlapping physical and virtual artifacts and tools to arrive at a co-operative design resolution. Within collaborative design, these artifacts take on an additional role. As embodiments of design ideas and actions, they become media for communication. Donald Schon asserts that design should be considered a form of making, rather than primarily a form of problem solving, information processing or research. Indeed the line separating creation from design is becoming increasingly blurred. For the design artifact itself may become a part of the design proposal—its virtual presence incorporated within a cybrid structure or object. We may in the future see a proliferation of cybrid settings that support collaborative, digital design. The technologies for this already exist in collaborative tools, networked computing, scanning and immersive media. However, it will take a creative vision to see how these disparate tools and devices can integrate within the ideal design setting.

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. 371-384
summary	In this paper, we describe the research we undertake to investigate the perception and comprehension of spatial volumes within immersive, non-immersive virtual environments and physical models and their translation to a tangible representation. We set up two related design experiments to investigate the outcome of creation, interpretation and communication of architectural design. One, being the analysis of a cubic structure, based on three-dimensional (3D) interlocking volumes and spaces; and the other, being the design of a 3D-maze together with text -based communication. Collaboratively participants create, assess and analyse spatial relationships of volumes and spaces of a 3D maze structure or construct models of these spaces. The objective of our study is to identify how designers perceive space in Virtual Environments (VE) and communicate design ideas by using VE versa conventional methods of two-dimensional depictions such as paper and pen or 3D representations such as physical models. We investigate issues of quality, accuracy, understanding, communicating and rebuilding of designed or experienced architectural compositions.

summary	The research project in progress in the School of Architecture at the Izmir Institute of Technology includes documentation and reconstruction (by 3D modeling in electronic media) of damaged and lost early modern buildings in the Izmir region. The research aims to analyze the differences between Izmir modern buildings and Universal Modern Style, and preserve information on architectural heritage for future generations. The project is at the phase of developing an interactive web-based historical database (HizmO) that includes data (information, images, technical drawings, VRML models) and visualization of the findings. This database aims to be a pioneer in Mediterranean Region for exhibition of relations between traditional architecture (especially Mediterranean locality) and modernism, and organization of a network and off-campus learning activity for Mediterranean architecture that serve as a guide for students, researchers and architects. This paper aims at introducing this research and discussing the application of the database “HizmO,” its aims and potential effects on education in architectural history.

title	Architectural Composition in Digital Space
doi	https://doi.org/10.52842/conf.ecaade.2003.587
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 587-590
summary	In this paper the possibilities of using the computers at course of architectural compositions are considered. As the start point of the new teaching method of architectural composition we used the course of tradition architectural composition, elaborated at our Faculty. The course of Digital Architectural Composition was finished in 2002. The main goal of using the new digital media for modelling architectural forms was checking the new possibilities of form creation. Traditionally, searching of forms at the conceptual design stage is performed by using sketches, drawings and physical models. Our new method showed that is possible to do the same thing using the computerbased 3D modelling, experiencing no physical limitations of the 'real' substance. At the same time, at the early design stages, when formal value is sought, computer modelling can be done almost intuitively. In ours work we try to find a creative way of using computer - transforming the tool into medium. The attention was paid on exploring the possibilities characteristic for computers and not available with traditional methods of modelling. Architect’s tradition tools are effectively replaced by a computer, which create a new way of doing things.

title	Computing And Manipulation In Design - A Pedagogical Experience Using Symmetry
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	The concept of symmetry has been usually restricted to bilateral symmetry, though in an extended sense it refers to any isometric transformation that maintains a certain shape invariant. Groups of operations such as translation, rotation, reflection and combinations of these originate patterns classified by modern mathematics as point groups, friezes and wallpapers (March and Steadman, 1974). This extended notion represents a tool for the recognition and reproduction of patterns, a primal aspect of the perception, comprehension and description of everything that we see. Another aspect of this process is the perception of shapes, primary and emergent. Primary shapes are the ones explicitly represented and emergent shapes are the ones implicit in the others (Gero and Yan, 1994). Some groups of shapes known as Semantic Shapes are especially meaningful in architecture, expressing visual features so as symmetry, rhythm, movement and balance. The extended understanding of the concept of symmetry might improve the development of cognitive abilities concerning the creation, recognition and meaning of forms and shapes, aspects of visual reasoning involved in the design process. This paper discusses the development of a pedagogical experience concerned with the application of the concept of symmetry in the creative generation of forms using computational tools and manipulation. The experience has been carried out since 1995 with 3rd year architectural design students. For the exploration of compositions based on symmetry operations with computational support we followed a method developed by Celani (2003) comprising the automatic generation and update of symmetry patterns using AutoCAD. The exercises with computational support were combined with other different exercises in each semester. The first approach combined the creation of two-dimensional patterns to their application and to their modeling into three-dimensions. The second approach combined the work with computational support with work with physical models and mirrors and the analysis of the created patterns. And the third approach combined the computational tasks with work with two-dimensional physical shapes and mirrors. The student’s work was analyzed under aspects such as Discretion/ Continuity –the creation of isolated groups of shapes or continuous overlapped patterns; Generation of Meta-Shapes –the emergence of new shapes from the geometrical relation between the generative shape and the structure of the symmetrical arrangement; Modes of Representation –the visual aspects of the generative shape such as color and shading; Visual Reasoning –the derivation of 3D compositions from 2D patterns by their progressive analysis and recognition; Conscious Interaction –the simultaneous creation and analysis of symmetry compositions, whether with computational support or with physical shapes and mirrors. The combined work with computational support and with physical models and mirrors enhanced the students understanding on the extended concept of symmetry. The conscious creation and analysis of the patterns also stimulated the student’s understanding over the different semantic possibilities involved in the exploration of forms and shapes in two or three dimensions. The method allowed the development of both syntactic and semantic aspects of visual reasoning, enhancing the students’ visual repertoire. This constitutes an important strategy in the building of the cognitive abilities used in the architectural design process.

summary	Digital visualization addresses representational challenges from within and without architecture. ‘Disciplinary’ digital visualization is used to explore, understand and communicate architectural information associated with the production of buildings. 3D modeling, rendering, animation and VR as well as the power of digital media to permit the seamless integration of various data types are unleashing completely new ways to display architecture. As digital power continues to increase and get cheaper, portability and wi-fi networks take root, and visualization work becomes even more main stream, we can expect growing changes in the way the design process is conducted, buildings are presented and documented, and the public and 3rd party’s demands from professional services. This demands a more conscious research/pedagogies aimed at developing new representation conventions.

source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	Several studies have used remote sensing to map patterns of e.g. deforestation or to analyse the rates of land use change. Thesestudies have proven useful for interpreting the causes of urbanization, deforestation etc. and the impact of such changes on theregion. Monitoring of change (e.g. deforestation or reforestation) is frequently perceived as one of the most important contributionsof remote sensing technology to the study of global ecological and environmental change (Roughgarden et al. 1991). Manyresearchers believe that the integration of remote sensing techniques within analysis of environmental change is essential if ecologistsare to meet the challenges of the future, specifically issues relating to global change; however, in practice, this integration has so farbeen limited (Griffiths & Mather 2000). Considerable difficulties are encountered in linking, on the one hand, the biologies oforganisms and the ecologies of populations to the fluxes of material and energy quantifiable at the level of ecosystems. In this paper,we concentrate on the methodological aspects of the delineation of landscape objects and touch the ecological application onlysuperficially but we elucidate the potential of the proposed methodology for several ecological applications briefly.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

summary	SPOT is a 3D environment for direct sunlight visualization. Implemented in Java 3D, SPOT features two distinct and complementary components: Time Projection and Navigable Animation for virtual interaction. SPOT supports multi-dimensional data visualization including sun angle variations with diurnal and annual cycles in threedimensional space. In SPOT users can sketch on any surface in the 3D environment to indicate the area for simulation. SPOT then generates a spatial distribution representation of the illuminance level on a selected surface over time, rendered with colors of varied gradients. SPOT also enables designers to visualize the temporal information of light distribution over time for a given point. For each point clicked on the 3D model, SPOT generates a calendar diagram where the X and Y axis represent the months of the year and the time of the day. The color of each cell of the calendar is the result of the calculation of the light amount reaching the selected point.
