title	Generative Systems Based on Animation Tools: Shaping Alternatives to Structure and Form in Architectural Design
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 245-251
doi	https://doi.org/10.52842/conf.ecaade.2007.245
summary	Our system is based on computer animation tools, employed in the context of architectural synthesis. The pipeline of the tool consists of “time” and space design constraints of boundaries / objects affecting a given architectural design, with an output of alternative designs. The alternative designs vary from the original according to their temporal and/or spatial distance from the original object on the animation time-line. Specific tools [shape driven curves, speed and time-line functions,parent child relationships, boolean operations, arrays, lattices etc.] empower the designer with the ability to transform his original idea in almost every way the designer likes in a completely visual, interactive and straightforward manner. The solutions sets change according to time, speed, location, configuration of the objects and/or the constraints and rules the designer/user configures. Previous work on our tool stemmed from the rule based structure of shape grammars, but has evolved to a tool where the designer does not have to define a rule set beforehand but does so as his idea evolves during design. The animation tools used are form independent (that is the designer can use any two- or- three-dimensional form) and can represent structural decisions in a given design. The independence from form makes the tool suitable for almost every kind of architectural design, be it experimental, real or conventional while the ability to represent structural decisions and relations of parts in a design implicitly help the designer/user acquire a clear picture of each design and solution set. Finally the possibility of a structured graph representing each solution is discussed, where the designer can evaluate the merit of an individual solution in terms of conforming to the initial core idea or where alternative spatial configurations evolve in a different structure from the original design.

title	Generative Systems Based on Animation Tools: Structure and Form of Core Ideas in Architectural Design
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.k1h
summary	The goal of the research described in this paper is the formulation of a generative system for architectural design, where a structured core architectural idea is the input and alternatives to that idea are the output. Specifically we present a production pipeline of architectural / spatial configurations using the context of animation and time based design tools. Our model consists of “time” and space design constraints of boundaries / objects affecting a given architectural design, thus producing an alternative solution for every timeframe of the animation cycle. Initially the designer shapes an idea using animation software tools, where each tool is actually a constraint or a grammar rule defined informally by the user/designer. The influence of the tools can vary according to time, speed, location, configuration of the object and/or the constraint itself. In some of these animations the designer has the ability to sidestep partially the issue of emergence by providing specific key - frames for the solution to follow. The use of animation tools [shape driven curves, speed and time-line functions, parent child relationships] in the shape generation of our model empowers the user/designer to configure whole sets of shapes and designs interactively and without the need to define every solution independently. Simultaneously, a different, time-focused view of our model describes its use on designs that develop different configurations over time. Thus a duality of our model is established : the animated schema may be either a sum or a family of various designs or the animated time-line may represent a single design which changes over time. Finally the possibility of a structured graph representing each solution is discussed, where the designer can evaluate the merit of an individual solution in terms of conforming to the initial core idea or where alternative spatial configurations evolve in a different structure from the original design.

title	Procedural Design of Urban Open Spaces
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 351-358
doi	https://doi.org/10.52842/conf.ecaade.2007.351
summary	This paper presents a novel approach for the automatic creation of vegetation scenarios in real or virtual 3D cities in order to simplify the complex design process and time consuming modeling tasks in urban landscape planning. We introduce shape grammars as a practical tool for the rule-based generation of urban open spaces. The automatically generated designs can be used for pre-visualization, master planning, guided design variation and digital content creation in general (e.g. for the entertainment industry). In a first step, we extend the CGA shape grammar by Müller et al. (2006) with urban planning operations. In a second step, we employ the possibilities of shape grammars to encode design patterns (Alexander et al., 1977). Therefore, we propose several examples of design patterns allowing for an intuitive high-level placement of objects common in urban open spaces (e.g. plants). Furthermore, arbitrary interactions between distinct instances of the vegetation and the urban environment can be encoded. With the resulting system, the designer can efficiently vegetate landscape and city parks, alleys, gardens, patios and even single buildings by applying the corresponding shape grammar rules. Our results demonstrate the procedural design process on two practical example scenarios, each one covering a different scale and different contexts of planning. The first example illustrates a derivation of the Garden of Versailles and the second example describes the usage of high-level rule sets to generate a suburbia model.

title	Construction of a Participatory Community Space Design System
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 99-106

summary	Residents’ active participation is necessary for a feasible community design from the planning stage to maintenance and management. it is necessary to show information related to a plan efficiently to facilitate understanding, and to consider a plan in a limited time. The purpose of this study is to develop a Community Space Design system (CSDS) that can use GIS data and Real-time simulation, in order to support comprehension of 3D area information during continuous development. Using CSDS, participants were able to treat various GIS data fixed, and a subject called the division and the disaster prevention of a community, which the object ground is holding can be understood visually on the same 3D space as real space. Because their solution was found, the design was accepted quickly.

doi	https://doi.org/10.52842/conf.acadia.2007.x.w9w
summary	The Ocean Tracking Network (OTN) is a large-scale global initiative that comprehensively monitors ocean conditions and marine life response to these conditions. Scientists are tagging sea creatures, from salmon to whales, with tiny transmitters so that their movements can be tracked for over 20 years by receivers placed at one-kilometre intervals along the ocean floor. Pressure sensors added to these receivers allow real-time measurements of ocean depth, temperature and salinity, all of which provide significant information about climate change and the likelihood of natural disasters such as tsunamis. On shore, scientists around the world can receive this information regularly and upload it to a central database, resulting in current and reliable international records.

title	Mobile Augmented Heritage: Enabling Human Life in Ancient Pompeii
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 396-415
summary	We propose a new methodology for real-time mobile mixed reality systems that feature realistic simulations of animated virtual human actors (clothes, body, skin, face) who augment real environments and re-enact staged storytelling dramas. Although initially targeted at Cultural Heritage Sites, the paradigm is by no means limited to such subjects. The abandonment of traditional concepts of static cultural artifacts or rigid geometrical and 2D textual augmentations with 3D, interactive, augmented historical character-based event representations in a mobile and wearable setup, is the main contribution of the described work as well as the proposed extensions to AR Enabling technologies: a VR/AR character simulation kernel framework with character to object interaction, a markerless camera tracker specialized for non-invasive geometrical registration on heritage sites and a PRT mixed reality illumination model for more consistent real-virtual real-time rendering. We demonstrate a real-time case study on the actual site of ancient Pompeii.

title	COMPUTER GAMING, BIOTECHNOLOGY AND ARCHITECTURE: EMBEDDING THE INTERSECTION WITHIN AN ARCHITECTURAL CURRICULUM.
source	AASA2007
summary	Today, leading computer games provide real time environments including spaces, objects and characters that range (by manipulating an enormous array of parameters and being subject to simulations of real world physics) from the super realistic to the super delirious. Biotechnology, although apparently unrelated, also requires the manipulation of information in space and time and promises to affect environments in a range of ways that is at least as extreme. The opportunities suggested by an intersection between Architecture, Computer Gaming and Biotechnology were instrumental in the creation of courses and topics for students in first year right through to students studying toward a Masters degree. This paper reflects on and critically reviews the implementation, strategies and outcomes of embedding the intersection between Computer Gaming and Biotechnology within an Architectural curriculum. It draws from the experience of over 500 students, two Universities and major technological shifts. It develops the notion of the experiment in design. In contrast with the introduction of computer gaming technology into a core first year course, that had the underlying aim of including these technologies as a part of a general design curriculum, the introduction of issues connecting architecture with biotechnology (through computer gaming technology) reflects the specific research agenda of the author and is not intended for general application across an architectural curriculum. For more general application it could be seen as a strategy to promote cross disciplinary collaboration through the concept of the ‘boundary object’.

title	Fuzzy Modelling for Early Architectural Design
source	International Journal of Architectural Computing vol. 5 - no. 4, pp. 589-610
summary	Fuzzy modelling is simultaneously an extension of existing modelling approaches and a negation of one of their main aspects, the crispness of their definition. As a digital equivalent of analogue sketching it allows designers to register and manipulate imprecise and uncertain information. In the framework of design representations fuzzy modelling supports the development of conceptual design models characterized by flexible definition and interaction. The main advantages of such models are fluency, abstraction and continuity, at a level similar to that of analogue techniques. In addition to that they offer the possibility of local autonomy, i.e. segmentation of a representation into self-regulating and cooperating components. Three alternative forms of fuzzy modelling are proposed: (1) Canonical objects with tolerances, (2) objects described by minimal and maximal values, and (3) point sets comprising discrete, autonomous particles that describe the object by their spatial or structural relationships.

title	Meta-Cognitive Mappings: Growing Neural Networks for Generative Urbanism
source	Generative Arts conference, Milan, 2007
summary	This paper examines the use of dynamic learning systems and adaptive topologies within neural networks models, and their implications as a tool for architectural mappings. The principal investigation is the ability of such systems to identify/ map/ model/ represent flows within dynamic data sets and identify topological relationships between these flows. A growing neural network [GNN] model is proposed, able to map dynamic data inputs over time. It is based on Kohonen’s early self-organising feature maps [SOM] and takes as its starting point previous work by CECA with neural networks in an architectural context, as well as other examples of neural gases, and GNNs, in order to develop a model capable of ‘autopoietic’ behaviour and ‘meta – learning’. The principal investigation is the ability of such a system to identify/ map/ model/ represent flows within dynamic data sets and identify topological relationships between these flows. As a case study, the proposed neural network model has been used to map ‘urban territory’, as part of an on going architectural research project, based in North London. The project takes the notion of ‘urban territories’ rather than ‘urban space’ as the field for interrogation, as a description of temporal spatial occupation space, rather than spatial physical permanence. Furthermore, the GNN may be used to identify the relationships between unused and vacant sites along the street. In this way, the GNN may become a means of proposing architectural interventions for these spaces, so that the territories of those that occupy it and the negotiations between them are not lost.

title	Conservation of Architectural Heritage:The Role of Digital Documentation Tools:The Need for Appropriate Teaching Material
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 240-253
summary	Currently, a wide range of digital sensors for capturing our architectural heritage are available. They offer the opportunity to acquire large sets of information in a relatively short time. These sensors include digital photography (photogrammetry-scaled rectified photography), total stations, laser scanners, high-resolution panoramic devices, etc. A lot of effort has been put in the application of these tools in the field of conservation, however a significant gap exists between the information needed by professionals working in the field of conservation and manufacturers claims of these new technologies. The realistic application of these tools for heritage documentation products needs to be addressed. Offering the architectural heritage community didactic material on how and when to use these tools appropriately can address this gap. This paper presents the teaching material being prepared under the CIPA/RecorDIM initiative to overcome these issues and begins to address the need for a common framework of standards in heritage documentation.

title	3 dimensional, digital, interactive, multilayered information models for enhancing decision making by two end-user groups within the Urban Planning industry: A Case Study to quantify the benefit or otherwise over alternative 2 dimensional systems
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 95-110
summary	This research investigates the potential of 3 dimensional (3D), digital, interactive, multilayered information models, to enhance users’ understanding of sets of geographic and building information, allowing them to make quicker and more informed decisions, than when using alternative 2D methods. The research aims to quantify the benefit or otherwise of 3D methods of information interrogation over 2D methods by developing a test based around the decision making of two widely disparate user-groups within the Urban Planning industry. The underlying purpose of the research is to examine the human ability to interact with and understand datasets of information which are represented in the digital world. This paper specifically focuses on the methodology by which a robust test is developed to be carried out, thus proving or disproving the advantages of 3D display of information when compared to 2D. The ability to apply this same test to additional case studies in the future is a major consideration in the research design. There is a specific focus on integrating and testing a range of research instruments to best establish “language” of the industry and user groups within it, before conducting the major case study. The final research approach adopted is develop and present functional prototype models in a focus group scenario, involving hands-on interactive comparable 2D and 3D tasks, individual feedback surveys and group discussions.

title	Developing an Interactive Architectural Meta-System for Contemporary Corporate Environments: An investigation into aspects of creating responsive spatial systems for corporate offices incorporating rule based computation techniques
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 199-212
summary	The research paper exemplifies upon an attempt to create a co-evolving (socio-cultural and technological) programmable spatiality with a strong underpinning in the domain of computation, interaction design and open system typologies for the generation of a constantly informed self-adaptive corporate office space (which addresses the behavioral patterns/preferences of its occupants). Architectural substantiations for such corporate bodies embodying dynamic business eco-systems usually tend to be rather inert in essence and deem to remain closed systemic entities, adhering to a rather static spatial program in accordance with which they were initially conceptualized. The research initiative, rather than creating conventional inert structural shells (hard components), thus focuses upon the development of a meta-system, or in other words the creation of a ‘soft’ computationally enriched open systemic framework (informational) which interfaces with the ‘hard’, material component and the users of the architectural construct (corporate offices). This soft space/meta system serves as a platform for providing the users with a democratic framework, within which they can manifest their own programmatic (activity oriented) combinations in order to create self designed spatial alternatives. The otherwise static/inert hard architectural counterpart, enhanced with contemporary technology thus becomes a physical interface prone to real-time spatial/structural and ambient augmentation to optimally serve its users.

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.

title	Mindful Spaces: Computational Geometry and the Conceptual Spaces in which Designers Operate
source	International Journal of Architectural Computing vol. 5 - no. 4, pp. 611-624
summary	Combinatorial computational geometry, while dealing with geometric objects as discrete entities, provides the means both to analyse and to construct relationships between these objects and relate them to other non-geometrical entities. This paper explores some ways in which this may be used in design through a review of six, one-semester-long design explorations by undergraduate and postgraduate students in the Flexible Modeling for Design and Prototyping course between 2004 and 2007. The course focuses on using computational geometry firstly to construct topologically defined design models based on graphs of relationships between objects (parametric design,) and concurrently to output physical prototypes from these "flexible models"(an application of numerical computational geometry). It supports students to make early design explorations. Many have built flexible models to explore design iterations for a static spatial outcome. Some have built models of real time responsive dynamic systems. In this educational context, computational geometry has enabled a range of design iterations that would have been challenging to uncover through physical analogue means alone. It has, perhaps more significantly, extended the students' own concept of the space in which they design.

summary	The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

title	Best Practice for Achieving Real-Time Virtual Reality Architectural Visualization
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.i4m
summary	Real-time rendering is the most fundamental aspect of the virtual reality technology, which is always, a balance between hardware advancement and efficient software algorithm upgrades on the one hand and the demands of the quality output on the other. As architects who utilize this technology, what we can do as users is to optimize the parameters we can control in the files we input to run the simulation. Thus the identification of the few variables we can control to prevent a lagging performance or ghosting which is no longer realtime. The frame rate above all is the measurement to determine whether a simulation is real-time or not. The research aim is to identify the biggest contributing factors among the few identified. The intention is to save time and effort by optimizing the selected factors in projects so that we do not have to optimize all of them. The workflow will also be a lot faster and projects can be done efficiently. The final part is to run satisfaction tests among users to evaluate those biggest contributing factors and the qualities acceptable by users. This is to eliminate the added processing power needed to run bigger files if they do not contribute much to improved quality.

title	A Group of Friends: The Las Americas Network, Virtual Studios, and Distance Education in Architecture
source	International Journal of Architectural Computing vol. 5 - no. 3, pp. 455-468
summary	This paper celebrates the human factor by describing how our collective vocation towards innovation in design education has inspired the development of an active network across the Americas. Ten years after its creation, the Las Americas Digital Research Network has generated a stream of innovative implementations. This is the first time that the main stream of these research activities is articulated into a peer-reviewed journal publication. The narrative of the paper follows a time-line that starts with the creation of the Las Americas Digital Research Network in 1996. Supported by such a framework the paper continues to describe the implementation of virtual design studios as collaborations nested at the core of the network. Finally, the paper explains how the virtual design studios provide fundamental feasibility for the development of network-mediated distance education curricula in architecture and the opening of a new dimension in the development and deployment of collaborative networks.

summary	Architects have always wanted to visually simulate internal space before beginning construction. Visualizations through the use of synthetics images, static scenes or animations, are a powerful tool which can contribute to understanding and therefore improve architectural proposals for better environment comfort, and energy efficiency. Real time interactive visualization of changes proposed by the architect during the design is a valuable resource, particularly during the initial phases. However, this type of real-time interactive visualization requires considerable computing power, which places restraints and reduces interactivity.

title	Analysis of Design Support for Kinetic Structures
source	Vienna University of Technology; Building Science & Technology
summary	This thesis attempts the formation and systemization of a basis of knowledge and information, which is indispensable to turn a design support for kinetic structures into representation by means of a 3d animating program. Representation of kinetic structures by means of the existing ordinary software sources is possible; Nevertheless, such representation lacks of different important features and functions and results eventually in the total absence of a real model of the construction, which is valuable to the user of the program especially in the field of the kinetics, where everything depends on the movement: design not only requires, but demands for visualisation. A personal interest in kinetic architecture and therefore in the physical movement of structural elements in a building, as well as an attempt to “fathom” the possibility of changing this concept to visualization and modern reality by the use of a software are the main incentives of this master thesis. First, a general research will be performed in order to check the existence of similar or semisimilar proposals. The area in which the research will be held is the Bibliography in kinetic architecture and parametric design. A comparison of animation and 3D prototype software in well-known programs will focus on whether virtual weather conditions are considered as a parameter to the animation of the structure of the programs and case studies of several existing kinetic structures will be performed, in order to point out flaws and/or helpful commands in the programs in connection with the presentation of kinetic architecture. Criteria for the choice of the software: ability to customise and to produce geometric modelling, animation in relation to time (video animation) and the simulation after taking into consideration weather factors. Finally, using the computer and the scripting language, based probably on the theory of parametric design and primitive instancing, a realistic simulation of different elements will be performed in relation to variable measurements of luminance, ventilation and temperature so as to render feasible the construction of a whole structure. The results of the thesis will be used in the future as the basic knowledge in the creation of software for simulation of kinetic architecture. This program will be used as a tool for the architect to present a building, where kinetic architecture will be applied and to create simulation of the kinetic movement through a library of the existing prefabricated elements which will be created with the help of this thesis.

summary	The use of Internet communication technologies in distributed teams has been carried out for well over 10 years. In this time, various methods to communicate and transfer information have been developed. A large amount of effort has been placed on enabling normal conversation to take place and it could be said, that with technologies like Skype, this is established. This enables planning partners to discuss, but we still need to convey what they are discussing. In short, the contents are still lacking. Technologies exist to allow users to share files or images, however this does not nearly reach the intensity or quality of discussions when partners are sitting together in front of a drawing or model. At best, screen sharing allows participants to see the same image but with low resolution and bad system response. The goal of the Intervision3D project is to allow distributed team members to discuss design issues with a common 3D model where participants can manipulate the model together in real time. In contrast to screen-sharing solutions, the Intervision3D project uses a server, which delivers a copy of the model to each conference participant. The server then coordinates the perspective views of all conference participants. One of the participants (usually the first) is initially designated as the speaker and he or she controls the views of the model through an intuitive walk/fly-through interface. The speed of the system is also buttressed by the simplicity of the application: as a Java applet, it is possible to start the Intervision3D system in any browser or as a separate applet on any system. As such, none of the participants need to install anything. The resolution of the model is optimized for each participant's browser and computer display. Currently, Intervision3D can import .3ds files and then render them using the JOGL Engine (Java Bindings for Open GL). JOGL allows the full Open GL suite to be used in rendering the model including lighting and textures: even normal PCs can do this quite well. The first implementation of the system is within an existing internet-based Design Studio and the paper elucidates how the first uses of the system have (partially) helped to increase the exchange of design ideas over the Internet. Through the Intervison3D system, the participants who have been separated by distance can once again discuss the same 3D model.
