title	Ivy: Bringing a Weighted-Mesh Representations to Bear on Generative Architectural Design Applications
doi	https://doi.org/10.52842/conf.acadia.2016.140
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 140-151
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	Normative Positions in Architectural Design - Deriving and Applying Design Methods
doi	https://doi.org/10.52842/conf.ecaade.2001.263
source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 263-268
summary	This paper presents a recently finished course of eight weeks where CAAD skills, design methodology, and architectural theory are combined to discuss possible perspectives on the use of the computer in design, and its influence on architecture. In the course, three contemporary architects were studied; Peter Eisenman, Ben van Berkel, and Greg Lynn. Each was discussed on aspects of ontology (which are the elements of discourse), design method (design process and organization of the process), and the use of the computer (techniques and approaches). These were linked with design theory, architectural theory, and CAD-theory. The reflection on the work of the architects resulted in a number of design methods for each architect. The design methods were adapted to the available technologies in the university as well as to the scope of the exercise, since the period of eight weeks for an exercise cannot compete with design processes in practice that take many participants and much time. The students then applied the design methods to a design task: student housing and an exhibition pavilion on the campus area of the university. The task was so devised, that students could focus on either architectural or urban design level with one of the design methods. Also, the choice of architects and accompanying design methods was made in such a way that students with low, medium, and advanced computer skills could take part in the course and exercise. In a workshop held at the Czech Technical University (CVUT) in Prague, the same procedure was used in a one-week period for a different design task, but in an otherwise almost identical setting with respect to the CAAD software used. The methods and material were easily transferred to the other setting. The students were able to cope with the task and produced surprising results in the short time span available. The paper will provide an overview of the course, discuss the pedagogical implications of the work, and discuss how this particular work can be generalized to incorporate other architects and approaches.

title	Creating a City Administration System (CAS) using Virtual Reality in an Immersive Collaborative Environment (ICE)
doi	https://doi.org/10.52842/conf.ecaade.2001.449
source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 449-453
summary	Current problems in administration of a city are found to be decentralized and noninteractive for an effective city management. This usually will result in inconsistencies of decision-making, inefficient services and slow response to a particular action. City administration often spends more money, time and human resource because of these problems. This research demonstrates our research and development of creating a City Administration System (CAS) to solve the problems stated above. The task of the system is to use information, multimedia and graphical technologies to form a database in which the city administrators can monitor, understand and manage an entire city from a central location. The key technology behind the success of the overall system uses virtual reality and immersive collaborative environment (ICE). This system employs emerging computer based real-time interactive technologies that are expected to ensure effective decisionmaking process, improved communication, and collaboration, error reduction, (Rafi and Karboulonis, 2000) between multi disciplinary users and approaches. This multi perspective approach allows planners, engineers, urban designers, architects, local authorities, environmentalists and general public to search, understand, process and anticipate the impact of a particular situation in the new city. It is hoped that the CAS will benefit city administrators to give them a tool that gives them the ability to understand, plan, and manage the business of running the city.

title	Shaping Passive Dehumidification for Hot and Humid Climates
source	ACADIA 2024: Designing Change [Volume 2: Proceedings of the 44th Annual Conference for the Association for Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9891764-8-9]. Calgary. 11-16 November 2024. edited by Alicia Nahmad-Vazquez, Jason Johnson, Joshua Taron, Jinmo Rhee, Daniel Hapton. pp. 275-288
summary	This research explores adapting architectural material systems as passive dehumidifiers using hygroscopic coatings and material geometry. The study validates increased passive dehumidification through an experimental hybrid lattice system. Human comfort is affected by temperature, humidity, and metabolic heat. In hot and humid climates, elevated tempera¬tures and humidity pose health risks like hyperthermia and mortality (Mora et al. 2017). Historically, vernacular architecture in tropical regions used hygroscopic materials like mud and thatch (Little and Morton 2001; Monzur 2018), to enhance passive cooling through natural ventilation. In contrast, modern construction often relies on mechanical air condi¬tioning, overlooking passive cooling strategies (Korachy 2020). Inspired by vernacular approaches to the built environment, this experiment adapts Isothermal Membrane-Assisted dehumidification (IMAD) technology (Qu et al. 2018) used in mechanical cooling systems to passively extract moisture through hybridization of geometry and matter. While membrane selectivity is adapted to many applications (Woods 2014), its integration into architectural design remains underexplored. Drawing inspiration from Indian Jaali systems, a lattice scaf¬fold is tested to study lattice morphology, and hygroscopic material properties for effective dehumidification at a building scale. Using computational simulation and physical testing, this proposal integrates IMAD into material geometry, focusing on increasing air velocity and passive dehumidification effectiveness (Figure 1).Ultimately, this research aims to rede¬fine architectural design by integrating innovative, passive dehumidification techniques, thus promoting survivability, enhancing human comfort and reducing reliance on mechan¬ical cooling in extreme climates.

title	A Critical Review of Problem Based Learning in Architectural Education
doi	https://doi.org/10.52842/conf.ecaade.2006.182
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 182-189
summary	There is limited research and discussion on pedagogical approaches in architectural education, simply because it is considered as one of the “unimportant” areas that researchers “do not bother studying” (Teymur, 2001). Problem Based Learning has been known to provide competent graduates in other professional disciplines, and, consequently, there have been attempts to utilise the same pedagogical approach in architectural education where PBL is seen as a potential solution to the problems encountered in architectural education. This paper critically reviews PBL implementations at TU Delft Netherlands and Newcastle University, N.S.W. Australia and draws conclusions with particular respect to the teaching of architectural computing

title	Adaptive hypermedia
source	User modelling and User-Adapted Interaction, volume 11, pp. 87-110, Kluwer
summary	Hypertext/hypermedia systems and user-model-based adaptive systems in the areas of learning and information retrieval have for a long time been considered as two mutually exclusive approaches to information access. Adaptive systems tailor information to the user and may guide the user in the information space to present the most relevant material, taking into account a model of the user's goals, interests and preferences. Hypermedia systems, on the other hand, are `user neutral': they provide the user with the tools and the freedom to explore an information space by browsing through a complex network of information nodes. Adaptive hypertext and hypermedia systems attempt to bridge the gap between these two approaches. Adaptation of hypermedia systems to each individual user is increasingly needed. With the growing size, complexity and heterogeneity of current hypermedia systems, such as the World Wide Web, it becomes virtually impossible to impose guidelines on authors concerning the overall organization of hypermedia information. The networks therefore become so complex and unstructured that the existing navigational tools are no longer powerful enough to provide orientation on where to search for the needed information. It is also not possible to identify appropriate pre-defined paths or subnets for users with certain goals and knowledge backgrounds since the user community of hypermedia systems is usually quite inhomogeneous. This is particularly true for Web-based applications which are expected to be used by a much greater variety of users than any earlier standalone application. A possible remedy for the negative effects of the traditional `one-size-fits-all' approach in the development of hypermedia systems is to equip them with the ability to adapt to the needs of their individual users. A possible way of achieving adaptivity is by modeling the users and tailoring the system's interactions to their goals, tasks and interests. In this sense, the notion of adaptive hypertext/hypermedia comes naturally to denote a hypertext or hypermedia system which reflects some features of the user and/or characteristics of his system usage in a user model, and utilizes this model in order to adapt various behavioral aspects of the system to the user. This book is the first comprehensive publication on adaptive hypertext and hypermedia. It is oriented towards researchers and practitioners in the fields of hypertext and hypermedia, information systems, andpersonalized systems. It is also an important resource for the numerous developers of Web-based applications. The design decisions, adaptation methods, and experience presented in this book are a unique source of ideas and techniques for developing more usable and more intelligent Web-based systems suitable for a great variety of users. The practitioners will find it important that many of the adaptation techniques presented in this book have proved to be efficient and are ready to be used in various applications.

title	The Role of Place in Designing a Learner Centred Virtual Learning Environment
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 187-200
summary	There are numerous approaches and tools for creating a virtual learning environment. The most common approach is to provide a repository of learning materials on a network to facilitate the distribution of the course content and to supplement this material with communications software such as email and bulletin boards. In this paper we highlight the role of place in creating a learning experience and its relevance to current learning theories. Architectural design becomes an important consideration when virtual learning environments are considered places. We present a framework for guiding the development of virtual learning environments that shows how place and design can combine with learning theories and technology. Finally, we draw on our experience in developing a virtual campus and virtual design studios to demonstrate how place and design can be the basis for virtual learning environments.

title	The e-learning action plan: designing tomorrow’s education
source	Communication from the Commission to the Council and the EuropeanParliament, COM(2001) 172 final, 28 March 2001
summary	The "eLearning: Designing tomorrow's education" initiative1 was adopted by the European Commission on 24 May 2000. Following up the conclusions of the Lisbon European Council, it set out the principles, objectives and lines of action of eLearning, defined as the use of new multimedia technologies and the Internet to improve the quality of learning by facilitating access to resources and services as well as remote exchanges and collaboration. The eLearning initiative was welcomed by the Ministers of Education and by the Feira European Council in June 2000. The eLearning initiative is part of the comprehensive eEurope Action Plan2, the aim of which is to allow Europe to exploit its strengths and overcome the barriers holding back the uptake of digital technologies. It also falls in with the Report on the concrete future objectives of education systems3 by adopting information and communication technology development as one of its objectives. The effectiveness of education systems depends entirely on the effectiveness of the approaches to teaching and learning. In order to be effective, the introduction of information and communication technologies will have to be accompanied by a far-reaching reorganisation of learning structures. The eLearning initiative is also of relevance for the candidate countries given the interest they have shown for the eEurope action plan.

title	3 x 2 Approaches to Design Management
doi	https://doi.org/10.52842/conf.ecaade.2001.220
source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 220-225
summary	Following the arguably successful introduction of building, project and real estate management to traditional architectural areas, design management is emerging as the new hot issue. One of the main arguments for it is the alleged low performance of the architect in the face of the technical complexity and operational intricacy that characterizes current design problems. In this respect, management is seen as the missing link in the architect’s methodical and operational framework. The paper suggests that this link derives more from the constraints of the domain and its subject matter rather than a management perspective. Design management refers to two main dimensions of architectural design, these of design method and of design subject. With respect to the first dimension we distinguish between three main categories: proscriptive, prescriptive and descriptive approaches. In the second dimension the distinction is between the coordination of the design process and that of the design product. The 3x2 matrix defined by these two dimensions stresses the significance of descriptive approaches for the informatization of the representation and communication of the design product. In this framework design information management emerges as an applied area of (computational) design theory that facilitates the amphidrome development of a design, i.e. not only from brief to postoccupancy but also from detail, case and precedent to design idea and solution, as well as the identification and management of critical moments, i.e. moments characterized by convergence of activities and hence extensive and intensive communication.

title	Design computing education: Developing a post-grad CAAD curriculum based on specific desing project
doi	https://doi.org/10.52842/conf.caadria.2001.315
source	CAADRIA 2001 [Proceedings of the Sixth Conference on Computer Aided Architectural Design Research in Asia / ISBN 1-86487-096-6] Sydney 19-21 April 2001, pp. 315-318
summary	The idea of teaching design computing through design-based approaches has been increasingly adopted over the past 15 years. However, most of the resulting experiments have been limited to specific courses within larger programmes. This approach has rarely affected CAAD curriculum. A glance at the syllabus of some CAAD programmes may reveal their non design-based nature. We describe here a post-graduate programme that has been structured around a specific design project through a set of courses in which the emphasis falls on the needs of the design process rather than on software categories.

title	Mouse.class: Experiments for Exploring Dynamic Behaviors in Urban Places
source	University of Washington, Design Machine Group
summary	Urban space comprises not only physical forms - buildings, streets, plazas, trees, etc. – but also the people 'acting on them'. The purpose of this thesis is to increase our awareness of behavior and environment relationships, focusing on local movement at the individual level in a pedestrian environment. The thesis describes the experiment Mouse.class, as a concept demonstration model, which allows users to create a 2D-virtual environment for accommodating autonomous agents, Mouse, to explore (pedestrian) dynamic behavior in relation to (urban) space. The program uses multi-agent technology to construct an individual-based simulation in which each agent employs individual behaviors. The agents have abilities to navigate through the environment using a behavior rule set derived from a wide range of research – both theoretical and empirical approaches – on spatial behavior in small-scale urban space. These simulated individuals also have the ability to improvise their actions according to the situations they find themselves in. In the simulation, each agent reacts to the space configuration, to specific attractions in the environment, as well as to other mice. The local movement of an individual is, therefore, the result of the interaction of its visual perception, motivation, and social actions. The program then tracks each movement – path of use – revealing patterns that emerge from interactions among the components of the environment. The exploration seeks to develop a way urban designers think of 'space' as fluid processes and recognize that objects in the urban environment can have radically differing effects, depending on the circumstances and contexts in which they exist. Indeed, people are parts of the environment.

title	Reflections on e-Design: The e-Studio Experience
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	The influence of digital media and information technology on architectural design education and practice is increasingly evident. The practice and learning of architecture is increasingly aided by and dependant on digital media. Digital technologies not only provide new production methods, but also expand our abilities to create, explore, manipulate and compose space. In contemporary design education, there is a continuous demand to deliver new skills in digital media and to rethink architectural design education in the light of the new developments in digital technology. During the academic years 2001-2003, I had the chance to lead the efforts to promote an effective use of digital media for design education at Department of Architecture, Jordan University of Science and Technology (JUST). Architectural curriculum at JUST dedicated much time for teaching computing skills. However, in this curriculum, digital media was taught in the form of "software use" education. In this context, digital media is perceived and used mainly as a presentation tool. Furthermore, Computer Aided Architectural Design and architectural design are taught in separate courses without interactions between the two.

title	Urban digital media: facilitating the intersection between science, the arts and culture in the arena of technology and building
doi	https://doi.org/10.52842/conf.caadria.2010.457
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 457-466
summary	The research presented in this paper investigates ways of providing better design applications for technologies in the field of Urban Digital Media (UDM). The work takes an emergent approach, evolving a design strategy through the early engagement of stakeholders. The paper discusses research in a design-led creative intersection between media technology, culture and the arts in the built environment. The case study discusses opportunities for the enhancement of a university campus experience, learning culture and community, through the provision of an integrated digital presence within campus architecture and urban spaces. It considers types of information architecture (Manovich, 2001) and designs for use in urban settings to create communication-rich, advanced and interactive designed spaces (Haeusler, 2009). The presented research investigates how to create a strategy for display technologies and networked communications to transform and augment the constructed reality of the built environment, allowing new formats of media activity.

summary	Two specific applications were developed in order to elaborate a database to consider the demands for the architectural and urbanistic patrimony inventory of Rosario, and to allow for the link with other city databases. One of these is to enter information and to make layers of different kinds of categories of buildings and groups of them. The other application facilitates the viewing and the performance of interrogations from different accesses. It is possible to visualize specific buildings with theirs details and to produce general maps showing different levels of information, such as buildings with patrimonial value that have definite degree of protection, or those belongs to the same category, etc, according to the special inquiry carried out.

title	Sagrada Família Rosassa: Global Computeraided Dialogue between Designer and Craftsperson (Overcoming Differences in Age, Time and Distance)
doi	https://doi.org/10.52842/conf.acadia.2001.076
source	Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 076-086
summary	The rose window (‘rosassa’ in Catalan) recently completed between the two groups of towers that make up the Passion Façade of Gaudí’s Sagrada Família Church in Barcelona measures eight metres wide and thirty-five metres in height [Figure 1]. There were four phases to the design based in three distinct geographical locations. The design was undertaken on site, design description in Australia some eighteen thousand kilometres distant, stone-cutting a thousand kilometres distant in Galicia, with the completion of the window in March 2001. The entire undertaking was achieved within a timeframe of fifteen months from the first design sketch. Within this relatively short period, the entire team achieved a new marriage between architecture and construction, a broader relationship between time-honoured craft technique with high technology, and evidence of leading the way in trans-global collaboration via the Internet. Together the various members of the project team combined to demonstrate that the technical office on site at the Sagrada Família Church now has the capacity to use ‘just-in-time’ project management in order to increase efficiency. The processes and dialogues developed help transcend the tyranny of distance, the difficult relationship between traditional craft based technique and innovative digitally enhanced production methods, and the three generational age differences between the youngest and more senior team members.

title	The impact of computer-based design tools for daylighting simulation and prediction for a built environment
doi	https://doi.org/10.52842/conf.caadria.2001.169
source	CAADRIA 2001 [Proceedings of the Sixth Conference on Computer Aided Architectural Design Research in Asia / ISBN 1-86487-096-6] Sydney 19-21 April 2001, pp. 169-179
summary	This paper investigates the application of computer daylighting simulation to provide qualitative assessment and comparison for designers to improve the built environment especially for non-technical architecture students. A comprehensive study was carried out to evaluate different daylighting design tools and to identify the limitation of current systems in the academic field. The paper will focus mainly on the dynamic information exchange between scientific visualization and the design decision-making process. Both architectural design studio environment and practical design problems in the real world setting were experimented and evaluated. Two case studies are presented: a proposed gallery space for a museum, and a detail architectural design of a community church. Architectural design alterations are proposed, simulated and discussed. The recursive feedback of the designers are studied and documented. Through a combination of qualitative assessment and comparison, designers can evaluate and compare different design options in the computing environment before implementing in the real world situation.

summary	It is all too common for technology companies to seek a new route to solving the same problem but for the most part the solutions address the effect and not the cause. The good old-fashioned pencil is the perfect example where inventors have sought to design-out the effect of the inherent brittleness of lead. Traditionally different methods of sharpening were suggested and more recently the propelling pencil has reigned king, the lead being supported by the dispensing sleeve thus reducing the likelihood of breakage. Developers convinced by the Single Building Model approach to design development have each embarked on a difficult journey to create an easy to use feature packed application. Unfortunately it seems that the two are not mutually compatible if we are to believe what we see emanating from Technology giants Autodesk in the guise of Architectural Desktop 3. The effect of their development is a feature rich environment but the cost and in this case the cause is a tool which is far from easy to use. However, this is only a small part of a much bigger problem, Interoperability. You see when one designer develops a model with one tool the information is typically locked in that environment. Of course the geometry can be distributed and shared amongst the team for use with their tools but the properties, or as often misquoted, the intelligence is lost along the way. The effect is the technological version of rubble; the cause is the low quality of data-translation available to us. Fortunately there is one company, which is making rapid advancements on the whole issue of collaboration, and data sharing. An old timer (Graphisoft - famous for ArchiCAD) has just donned a smart new suit, set up a new company called GDL Technology and stepped into the ring to do battle, with a difference. The difference is that GDL Technology does not rely on conquering the competition, quite the opposite in fact their success relies upon the continued success of all the major CAD platforms including AutoCAD, MicroStation and ArchiCAD (of course). GDL Technology have created a standard data format for manufacturers called GDL Objects. Product manufacturers such as Velux are now able to develop product libraries using GDL Objects, which can then be placed in a CAD model, or drawing using almost any CAD tool. The product libraries can be stored on the web or on CD giving easy download access to any building industry professional. These objects are created using scripts which makes them tiny for downloading from the web. Each object contains 3 important types of information: · Parametric scale dependant 2d plan symbols · Full 3d geometric data · Manufacturers information such as material, colour and price Whilst manufacturers are racing to GDL Technologies door to sign up, developers and clients are quick to see the benefit too. Porsche are using GDL Objects to manage their brand identity as they build over 300 new showrooms worldwide. Having defined the building style and interior Porsche, in conjunction with the product suppliers, have produced a CD-ROM with all of the selected building components such as cladding, doors, furniture, and finishes. Designing and detailing the various schemes will therefore be as straightforward as using Lego. To ease the process of accessing, sizing and placing the product libraries GDL Technology have developed a product called GDL Object Explorer, a free-standing application which can be placed on the CD with the product libraries. Furthermore, whilst the Object Explorer gives access to the GDL Objects it also enables the user to save the object in one of many file formats including DWG, DGN, DXF, 3DS and even the IAI's IFC. However, if you are an AutoCAD user there is another tool, which has been designed especially for you, it is called the Object Adapter and it works inside of AutoCAD 14 and 2000. The Object Adapter will dynamically convert all GDL Objects to AutoCAD Blocks during placement, which means that they can be controlled with standard AutoCAD commands. Furthermore, each object can be linked to an online document from the manufacturer web site, which is ideal for more extensive product information. Other tools, which have been developed to make the most of the objects, are the Web Plug-in and SalesCAD. The Plug-in enables objects to be dynamically modified and displayed on web pages and Sales CAD is an easy to learn and use design tool for sales teams to explore, develop and cost designs on a Notebook PC whilst sitting in the architects office. All sales quotations are directly extracted from the model and presented in HTML format as a mixture of product images, product descriptions and tables identifying quantities and costs. With full lifecycle information stored in each GDL Object it is no surprise that GDL Technology see their objects as the future for building design. Indeed they are not alone, the IAI have already said that they are going to explore the possibility of associating GDL Objects with their own data sharing format the IFC. So down to the dirty stuff, money and how much it costs? Well, at the risk of sounding like a market trader in Petticoat Lane, "To you guv? Nuffin". That's right as a user of this technology it will cost you nothing! Not a penny, it is gratis, free. The product manufacturer pays for the license to host their libraries on the web or on CD and even then their costs are small costing from as little as 50p for each CD filled with objects. GDL Technology has come up trumps with their GDL Objects. They have developed a new way to solve old problems. If CAD were a pencil then GDL Objects would be ballistic lead, which would never break or loose its point. A much better alternative to the strategy used by many of their competitors who seek to avoid breaking the pencil by persuading the artist not to press down so hard. If you are still reading and you have not already dropped the magazine and run off to find out if your favorite product supplier has already signed up then I suggest you check out the following web sites www.gdlcentral.com and www.gdltechnology.com. If you do not see them there, pick up the phone and ask them why.

summary	Architecture is a mixture of art and technique. This implies that the architect deals not only with engineering aspects that can be easily quantified and thereafter processed, but deals with aesthetics as well which is in first place qualitative and therefore rather difficult to estimate and numerically represent. As an example, in such cases, these ‘qualitative quantities’ are expressed in linguistic form which should be somehow expressed in numerical form in order to treat such data by powerful and conclusive numerical analysis methods. Expressions such as: bright colour, light room, large space are some of these examples. These expressions are fuzzy concepts whose actual interpretation is hidden and all of them together attach a qualitative value to a certain space. To deal with such information the emerging technologies of the last decade can provide an important aid. One of them is the soft computing technology that can deal with such soft data. In this paper, based on the case studies, we explain the potential of using soft computing techniques.

title	Information Rich 3D Computer Modeling of Urban Environments
source	Working Paper 35, Centre for Advanced Spatial Analysis Working Papers; London, August 2001
summary	We are living in an increasingly information rich society. Geographical Information Systems now allow us to precisely tag information to specific features, objects and locations. The Internet is enabling much of this information to be accessed by a whole spectrum of users. At CASA we are attempting to push this technology towards a three-dimensional GIS, that works across the Internet and can represent significant chunks of a large city. We believe that the range of possible uses for such technology is diverse, although we feel that urban planning is an area that can benefit greatly. An opportunity to push this ìplanning technologyî arose when CASA won a tender from Hackney Council to develop a dynamic website for community participation in the process of regenerating the Woodberry Down Estate. This is a run down part of northeast London that is undergoing a major redevelopment. CASA has developed a system that not only informs the local residents about the redevelopment process but it also enables them to use dynamic visualisations of the ìbefore and after effectsî of different plans, and then to discuss and vote on the variety of options.
