summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

title	No More Fear or Doubt: Electronic Architecture in Architectural Education
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	Operating electronic and Internet worked tools for Architectural education is an important, and merely a prerequisite step toward creating powerful tele-collabortion and tele-research in our Architectural studios. The design studio, as physical place and pedagogical method, is the core of architectural education. The Carnegie Endowment report on architectural education, published in 1996, identified a comparably central role for studios in schools today. Advances in CAD and visualization, combined with technologies to communicate images, data, and “live” action, now enable virtual dimensions of studio experience. Students no longer need to gather at the same time and place to tackle the same design problem. Critics can comment over the network or by e-mail, and distinguished jurors can make virtual visits without being in the same room as the pin-up—if there is a pin-up (or a room). Virtual design studios (VDS) have the potential to support collaboration over competition, diversify student experiences, and redistribute the intellectual resources of architectural education across geographic and socioeconomic divisions. The challenge is to predict whether VDS will isolate students from a sense of place and materiality, or if it will provide future architects the tools to reconcile communication environments and physical space.

title	The MIT Design Studio of the Future: Virtual Design Review Video Program
source	Proceedings of ACM CSCW'96 Conference on Computer-Supported Cooperative Work 1996 p.10
summary	The MIT Design Studio of the Future is an interdisciplinary effort to focus on geographically distributed electronic design and work group collaboration issues. The physical elements of this virtual studio comprise networked computer and videoconferencing connections among electronic design studios at MIT in Civil and Environmental Engineering, Architecture and Planning, Mechanical Engineering, the Lab for Computer Science, and the Rapid Prototyping Lab, with WAN and other electronic connections to industry partners and sponsors to take advantage of non-local expertise and to introduce real design and construction and manufacturing problems into the equation. This prototype collaborative design network is known as StudioNet. The project is looking at aspects of the design process to determine how advanced technologies impact the process. The first experiment within the electronic studio setting was the "virtual design review", wherein jurors for the final design review were located in geographically distributed sites. The video captures the results of that project, as does a paper recently published in the journal Architectural Research Quarterly (Cambridge, UK; Vol. 1, No. 2; Dec. 1995).

summary	This paper presents a teaching experience involving students and professors from various universities, in Italy and abroad, which began in 1996 and is still on going. The Virtual Studios on the Internet (VSI) have some features in common with the Teaching Studios planned for the new programme of the faculties of Architecture in Italian universities. These are the definition of a common design theme, and the participation of disciplinary teachers. The greatest difference is in the modes of collaboration, which is achieved through information and communication technologies. The chief result of this is that the various work groups in different places can work and collaborate at the same time: the computer networks provide the means to express, communicate and share the design project.

title	A digital Procedure of Building Construction: A practical project
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title	Collaborative Design System with Network Technologies in Design Projects
doi	https://doi.org/10.52842/conf.caadria.1996.269
source	CAADRIA ‘96 [Proceedings of The First Conference on Computer Aided Architectural Design Research in Asia / ISBN 9627-75-703-9] Hong Kong (Hong Kong) 25-27 April 1996, pp. 269-286
summary	This paper depicts the work of the team of researchers at the Sasada Laboratory in the area of collaborative design and the integration of global area network such as the Internet in order to extend the architectural studio into cyber-space. The Sasada Laboratory is located at the University of Osaka, Faculty of Engineering, Department of Environmental engineering, Japan. The portfolio of the Laboratory is extensive and impressive. The projects which were produced by the men and women of the Laboratory range from the production of databases and computer simulation of several segments of different cities throughout the world to specific studies of architectural monuments. The work performed on the databases was varied and included simulation of past, present, and future events. These databases were often huge and very complex to build. They presented challenges that sometimes seemed impossible to overcome. Often, specialised software, and in some cases hardware, had to be designed on the "fly” for the task. In this paper, we describe the advances of our research and how our work led us to the development of hardware and software. Most importantly, it depicts the methodology of work which our lab undertook. This research led to the birth of what we call the "Open Development Environment” (ODE) and later to the networked version of ODE (NODE). The main purpose of NODE is to allow various people, usually separated by great distances, to work together on a given project and to introduce computer simulation into the working environment. Today, our laboratory is no longer limited to the physical location of our lab. Thanks to global area networks, such as the Internet, our office has been extended into the virtual space of the web. Today, we exchange ideas and collaborate on projects using the network with people that are spread over the five continents.

summary	This paper brings some of the debate within educational theory to bear on CAAD teaching, outlining the contributions of conservatism, critical theory, radical hermeneutics and pragmatism. The paper concludes by recommending that CAAD teaching move away from conservative concepts of teaching, design and technology to integrate it into the studio. In a highly illuminating book on education theory, Shaun Gallagher (1991) outlines four current views on education that correspond to four major positions in contemporary social theory and philosophy. I will extend these categories to a consideration of attitudes to information technology, and the teaching of computing in architecture. These four positions are conservatism, critical theory, radical hermeneutics, and pragmatism. I will show how certain issues cluster around them, how each position provides the focus of various discursive practices, or intellectual conversations in contemporary thinking, and how information technology is caught up in those conversations. These four positions are not "cognitive styles," but vigorously argued domains of debate involving writers such as Gadamer, Habermas and Derrida about the theory of interpretation. The field of interpretation is known as hermeneutics, which is concerned less with epistemology and knowledge than with understanding. Interpretation theory applies to reading texts, interpreting the law, and appreciating art, but also to the application of any practical task, such as making art, drawing, defining and solving problems, and design (Coyne and Snodgrass, 1995). Hermeneutics provides a coherent focus for considering many contemporary issues and many domains of practice. I outline what these positions in education mean in terms of CAAD (computer-aided architectural design) in the curriculum.

summary	Design reviews and discussions are fundamental to the process of design. The ability to digitally represent three dimensional space in real-time is a new and potentially persuasive method for reviewing and analyzing a design proposal. The development of real-time rendering engines and network protocols supporting distributed interaction makes possible the idea of a shared virtual environment for architectural collaboration. This paper presents a system which facilitates the review of an architectural design between multiple participants who are remotely distributed.

title	Modeling and rendering architecture from photographs: a hybrid geometry- and image-based approach
source	SIGGRAPH'96, New Orleans, Louisiana
summary	We present a new approach for modeling and rendering existing architectural scenes from a sparse set of still photographs. Our modeling approach, which combines both geometry-based and imagebased techniques, has two components. The first component is a photogrammetricmodelingmethodwhich facilitates the recovery of the basic geometry of the photographed scene. Our photogrammetric modeling approach is effective, convenient, and robust because it exploits the constraints that are characteristic of architectural scenes. The second component is a model-based stereo algorithm, which recovers how the real scene deviates from the basic model. By making use of the model, our stereo technique robustly recovers accurate depth from widely-spaced image pairs. Consequently, our approach canmodel large architectural environmentswith far fewer photographs than current image-based modeling approaches. For producing renderings, we present view-dependent texture mapping, a method of compositing multiple views of a scene that better simulates geometric detail on basic models. Our approach can be used to recover models for use in either geometry-based or image-based rendering systems. We present results that demonstrate our approach's ability to create realistic renderings of architectural scenes from viewpoints far from the original photographs.

title	CAD Systems for early design phases or CAD systems for designers' early phases
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	Most of the problems, related with the use of CAD systems are the results of some general principles; the philosophy that, those systems are based on. Therefore, mainly the relation between these principles and early design phase performance of CAD systems and designers are discussed in this paper. The circumstances of novice CAD user architects in Turkey is considered first. In formation of the research, the knowledge gained during my personal experience based on real cases from the university (education, research) and practice (design, consulting) is used. Beside this the results of a survey including a serious of interviews projecting the opinions of the architects is used. Vendors of commonly used CAD systems were interviewed. In this manner to answer the main question about the relation of "CAD" and "early design phase" the answers of some following questions and facts were investigated: What means CAD for architects? What are the main purposes of using CAD? Are CAD systems sufficient to be used in early design phases in terms of either hardware and / or software, or should we say thinkware?. The advantages and disadvantages of using CAD. The target user fact and its consequences (the difference between general purpose systems and the sophisticated architectural systems). Should we adapt to computerized way of thinking? Is 3D a basic feature? What are the education related problems of CAD? Is software integration problem solved? Modularity concept for CAD systems. What is the minimum time, and the budget required for a start? The illegal software use problem Complaints, demands, needs and thanks of architects? Simply, what do architects expect from CAD during design process and particularly in early phases (both of design and designer)? Do CAD systems match this?

title	Teaching Architectural Composition Through the Medium of Virtual Reality Modelling
source	Approaches to Computer Aided Architectural Composition [ISBN 83-905377-1-0] 1996, pp. 91-102
summary	This paper describes an experimental teaching programme to enable architectural students in the early years of their undergraduate study to explore their understanding of the principles of architectural composition, by the creation and experience of architectural form and space in simple virtual reality environments. Principles of architectural composition, based upon the ordering and organisation of typological architectural elements according to established rules of composition, are introduced to the students, through the study of recognised works of architectural design theory. Virtual reality modelling is then used as a tool by the students for the testing and exploration of these theoretical concepts. Compositional exercises involving the creation and manipulation of a family of architectural elements to create form and space within a three dimensional virtual reality environment are carried out using Superscape VRT, a PC based virtual reality modelling system. The project seeks to bring intuitive and immersive computer based design techniques directly into the context of design theory teaching and studio practice, at an early stage in the architectural education process.

summary	New technological achievements and research results allow for the creation of innovative design tools for architects, that do not originate from paper-based paradigms but instead make optimised use of the present technology and programming concepts. The core of our system is comprised of an intuitive interactive modelling tool. It runs in a virtual reality set-up, where the user can use 3D glasses to experience rooms and 3D input devices to model in three dimensions. The interface is free from widget-like buttons or menus, so that the user is undisturbed when moving into the virtual world of the design. The system can also run in a distributed fashion, so that a number of users can look at and modify the same design. The 3D model can be generated in a sketch-like fashion using solids and voids, void modelling turns out to be very valuable for architectural design. The objects in this system can contain forms of intelligence to produce such behaviour as: falling because of gravity, collision avoidance, and autonomous motion. Interactive behaviour can also be assigned to the objects. Autonomous Agents are added to the system to enhance the designer support. These are agents that enhance the virtual environment, agents that take over tasks, and agents that help to test the design. The system shows new interface and interaction approaches that support the architectural design process intelligently.

summary	Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title	Fabrication with Residual Wood through Scanning Optimization and Robotic Milling

summary	The project deals with the use of residual wood of tree stumps and roots through scanning, optimization and robotic milling. Wood logging residue makes up to 50 percent of the trees harvested biomass. (Hakkila and Parikka 2002). Among prevailing strategies is leaving residue on site, and recovering residue for bioenergy. (Perlack and others 2005). The project explores the third strategy, using parts of the logging residue for fabrication, which may reduce the overall amount of wood logging volume. Furthermore approach aims for applying residue in its natural form and taking advantage of specific local characteristics of wood (Desch and Dinwoodie 1996). The project applies the strategy on working with stump and roots of an oak tree. Due to considerations of scale, available milling technics and available resources, chosen goal of the approach is to create a functioning chair prototype. Among the problems of the approach is the complex shape of the residue, uneven quality of wood, varying humidity and contamination with soil. After cleaning and drying, the stump is scanned and a 3D model is created. The 3D model od a stump is confronted with a 3D modelled limits of the goal typology (height, width, length, sitting surface area and overal volume of a chair) and topological optimization algorithm is used to iteratively reach the desired geometry. Unlike in established topological optimization proces, which aims for a minimal volume, the project attempts to achieve required qualities with removing minimal amount of wood. Due to geometric complexity of both stump and goal object, milling with an 6axis industrial robotic arm and a rotary table was chosen as a fabrication method. The object was clamped to the board (then connected to a rotary table) in order to provide precise location and orientation in 3D space. The milling of the object was divided in two parts, with the seating area milled in higher detail. Overall process of working with a residual wood that has potential to be both effective and present aesthetic quality based on individual characteristics of wood. Further development can integrate a generative tool which would streamline the design and fabrication proces further.

title	An Accelerated Rendering Algorithm for Stereoscopic Display

summary	With the development of the scientific visualization and the virtual environment techniques, stereo viewing systems have not been used extensively. In this paper, we present an accelerated rendering algorithm for stereoscopic display. As the difference between the left view and the right view is slight, we generate the right view by a transformation of the left view conforming to the stereo disparity. The problem of visibility change of a few polygons during the transformation is discussed and an efficient algorithm is developed for filling the holes that may arise in the right view after the transformation. This method makes fully use of the coherence between the left view and the right view. Experiments prove its efficiency.

title	Awareness Space in Distributed Social Networks

summary	In the real work environment we are constantly aware of the presence and activity of others. We know when people are away from their desks, whether they are doing concentrated work, or whether they are available for interaction. We use this peripheral awareness of others to guide our interactions and social behaviour. However, when teams of workers are spatially separated we lose 'awareness' information and this severely inhibits interaction and information flow. The Theatre of Work (TOWER) aims to develop a virtual space to help create a sense of social awareness and presence to support distributed working. Presence, status and activity of other people are made visible in the theatre of work and allow one to build peripheral awareness of the current activity patterns of those who we do not share space with in reality. TOWER is developing a construction set to augment the workplace with synchronous as well as asynchronous awareness. Current, synchronous activity patterns and statuses are played out in a 3D virtual space through the use of symbolic acting. The environment itself however is automatically constructed on the basis of the organisation's information resources and is in effect an information space. Location of the symbolic actor in the environment can therefore represent the focus of that person's current activity. The environment itself evolves to reflect historic patterns of information use and exchange, and becomes an asynchronous representation of the past history of the organisation. A module that records specific episodes from the synchronous event cycle as a Docudrama forms an asynchronous information resource to give a history of team work and decision taking. The TOWER environment is displayed using a number of screen based and ambient display devices. Current status and activity events are supplied to the system using a range of sensors both in the real environment and in the information systems. The methodology has been established as a two-stage process. The 3D spatial environment will be automatically constructed or generated from some aspect of the pre-existing organisational structure or its information resources or usage patterns. The methodology must be extended to provide means for that structure to grow and evolve in the light of patterns of actual user behaviour in the TOWER space. We have developed a generative algorithm that uses a cell aggregation process to transcribe the information space into a 3d space. In stage 2 that space was analysed using space syntax methods (Hillier & Hanson, 1984; Hillier 1996) to allow the properties of permeability and intelligibility to be measured, and then these fed back into the generative algorithm. Finally, these same measures have been used to evaluate the spatialised behaviour that users of the TOWER space show, and will used to feed this back into the evolution of the space. The stage of transcription from information structure to 3d space through a generative algorithm is critical since it is this stage that allows neighbourhood relations to be created that are not present in the original information structure. It is these relations that could be expected to help increase social density.
