title	The End of Methodology - Towards New Integration
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	The present paper is devoted to the deliberation on the genesis and development of designing from the point of view of the potential use of computers in the process. Moreover, it also presents the great hopes which were connected with the use of the systematic designing methods in the 1960’s, as well as the great disappointment resulting from the lack of concrete results. At this time a great deal of attention was paid to the process of design as a branch of a wider process of problem-solving. Many people believed that the intuitive methods of design traditionally used by architects were incapable of dealing with the complexity of the problems to be solved. Therefore, the basic problem was the definition of a vertical structure of the designing process, which would make it possible to optimise each process of architectural design. The studies of design methodology directed at the codification of the norms of actions have not brought about any solutions which could be commonly accepted, as the efforts to present the designing process as a formally logical one and one that is not internally “uncontrary” from the mathematical point of view, were doomed to fail. Moreover, the difficulties connected with the use of the computer in designing were caused by the lack of a graphic interface, which is so very characteristic of an architect’s workshop. In result, the methodology ceased to be the main area of the architect’s interest and efforts were focused on facilitating the method of the designer’s communication with the computer. New tools were created, which enabled both the automatic generation of diversity and the creation of forms on the basis of genetic algorithms, as well as the presentation of the obtained results in the form of rendering, animation and VRML. This was the end of the general methodology of designing and the beginning of a number of methods solving the partial problems of computer-supported design. The present situation can be described with the words of Ian Stewart as a “chaotic run in all directions”. An immediate need for new integration is felt. Cyber-real space could be a solution to the problem. C-R-S is not a virtual reality understood as an unreal world. Whilst VR could be indeed treated as a sort of an illusion, C-R-S is a much more realistic being, defining the area in which the creative activities are taking place. The architect gains the possibility of having a direct contact with the form he or she is creating. Direct design enables one to creatively use the computer technology in the designing process. The intelligent system of recognising speech, integrated with the system of virtual reality, will allow to create an environment for the designer – computer communication which will be most natural to the person. The elimination of this obstacle will facilitate the integration of the new methods into one designing environment. The theoretical assumptions of such an environment are described in the present paper.

title	Analysis and the descriptive approach
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	The rise of consciousness concerning the quality of working and living conditions has been a permanent though frequently underplayed theme in architecture and building since the reconstruction period. It has led to an explosive growth of programmatic requirements on building behaviour and performance, thus also stimulating the development of design analysis. The first stage of development was characterized by the evolution of prescriptive systems. These reversed the structure of pre-existing proscriptive systems into sequences of known steps that should be taken in order to achieve adequate results. Prescriptive systems complemented rather than replaced proscriptive ones, thereby creating an uncertain mixture of orthodoxy and orthopraxy that failed to provide design guidance for improving design performance and quality.The second stage in the development of design analysis focuses on descriptive methods and techniques for analyzing and supporting evaluation. Technologies such as simulation and scientific visualization are employed so as to produce detailed, accurate and reliable projections of building behaviour and performance. These projections can be correlated into a comprehensive and coherent description of a building using representations of form as information carriers. In these representations feedback and interaction assume a visual character that fits both design attitudes and lay perception of the built environment, but on the basis of a quantitative background that justifies, verifies and refines design actions. Descriptive analysis is currently the most promising direction for confronting and resolving design complexity. It provides the designer with useful insights into the causes and effects of various design problems but frequently comes short of providing clear design guidance for two main reasons: (1) it adds substantial amounts of information to the already unmanageable loads the designer must handle, and (2) it may provide incoherent cues for the further development of a design. Consequently the descriptive approach to analysis is always in danger of been supplanted by abstract decision making.One way of providing the desired design guidance is to complement the connection of descriptive analyses to representations of form (and from there to synthesis) with two interface components. The first is a memory component, implemented as case-bases of precedent designs. These designs encapsulate integrated design information that can be matched to the design in hand in terms of form, function and performance. Comparison between precedents with a known performance and a new design facilitate identification of design aspects that need be improved, as well as of wider formal and functional consequences. The second component is an adaptive generative system capable of guiding exploration of these aspects, both in the precedents and the new design. The aim of this system is to provide feedback from analysis to synthesis. By exploring the scope of the analysis and the applicability of the conclusions to more designs, the designer generates a coherent and consistent collection of partial solutions that explore a relevant solution space. Development of the first component, the design case-bases, is no trivial task. Transformability in the representation of cases and flexible classification in a database are critical to the identification and treatment of a design aspect. Nevertheless, the state of the art in case-based reasoning and the extensive corpus of analysed designs provide the essential building blocks. The second component, the adaptive generative system, poses more questions. Existing generative techniques do not possess the necessary richness or multidimensionality. Moreover, it is imperative that the designer plays a more active role in the control of the process than merely tweaking local variables. At the same time, the system should prevent that redesigning degenerates into a blind trial-and-error enumeration of possibilities. Guided empirical design research arguably provides the means for the evolutionary development of the second component.

title	Learning and Contamination in Virtual Worlds
source	International Conference on Generative Art
summary	The most recent advances of artificial life scientific research are opening up a new frontier: the creation of simulated life environments populated by autonomous agents. In these environments artificial beings can interact, reproduce and evolve [4, 6, 15], and can be seen as laboratories whereto explore the emergence of social behaviors like competition, cooperation, relationships and communication [5, 7] . It is still not possible to approach a reasonable simulation of the incredible complexity of human or animal societies, but these environments can be used as a scientific orartistic tool to explore some basic aspects of the evolution [1, 2, 3, 9, 10, 11, 12, 13, 14]. The combination of these concepts with robotics technology or with immersive-interactive 3D environments (virtual reality) are changing quickly well known paradigms like digital life, manmachineinterface, virtual world. The virtual world metaphor becomes interesting when the artificial beings can develop some form of learning, increasing their performances, adaptation, and developing the ability to exchange information with human visitors. In this sense the evolution enhances the creative power and meaningful of these environments, and human visitors experience an emotion of a shift from a simplified simulation of the reality to a real immersion into an imaginary life. We may think that these realization are the first sparks of a new form of life: simulated for the soft-alife thinkers, real for the hard-alife thinkers, or a simple imaginary vision for the artists.

title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
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. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title	Evolution of Digital Design Teaching: A Course as Microcosm for Educational Issues
source	ACADIA Quarterly, vol. 20, pp. 13-17
doi	https://doi.org/10.52842/conf.acadia.2001.013
summary	Despite widespread use of computers in the architectural profession, computer use in architectural education remains uneven. The challenge to educators becomes apparent in examining the evolution of an introductory course. In four years, the teaching initiatives illuminate the crucial issues:* Content focus (what): computer techniques supporting design concepts, selection of design and communication applications / * Delivery techniques (how): - Organizing framework: staffing, course format - Teaching tools: web resources, online bulletin boards, online quizzes and gradebook. These efforts have produced gradual progress. Major successes include development of successful assignments and resources, balance of exercise types, and skill improvement through competency exams. On the other hand, addressing different skill levels, providing personal attention in an efficient way and overcoming equipment impediments remain a challenge. Outside the course, the overall curricular framework needs to be adjusted to prepare for and reinforce learning within the course. Results from initiatives inside and outside of the classroom are discussed.

title	THE INTEGRATED DESIGN STUDIO: A VIEW BEHIND THE SCENES:Liquid Campus 3
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 545-548

summary	Over 10 months ending in July 2005, architecture students from Aachen, Karlsruhe and Weimar took part in a design studio that differed significantly from other studios in that the result of the studio was a 1:1 realisation of the design. This is part of an evolution of the virtual faculty of architecture “Liquid Campus”, founded in 2001, which has seen the complexity of the projects steadily rise and this continued in the Project “Ein Fest: Ein Dach”. The integrated studio is arranged to encourage an active, economic and transparent learning process, which encompasses design, communication and cooperation issues. The stated goal at the beginning of the two-semester process is to build and although only a few of the ideas are realised, all participants are involved in the realisation. In this case, the project was to create “roofs” for an open-air concert for 200,000 people in Karlsruhe, Germany. The planning was carried out using the Netzentwurf platform, with which the authors have several years experience.

title	Awareness Space in Distributed Social Networks
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 615-628
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.

summary	This paper outlines the evolution of digital management systems used in the School of Architecture and building at Deakin University from 2001 to the present. These systems have been implemented to support a curriculum development programme in the design, construction and computing units. Two school-based information management systems are discussed in depth: low-tech network submission system and Bentley Systems Inc’s ProjectWise. Early experiences in using a universitybased system are also reported on. Lessons learnt from three years experience in managing digital resources for design education have informed the development of a growing digital culture in the architectural and construction management curricula. Whilst digital curriculum design and management systems supporting this curriculum have been developed effectively in this school, full optimization of IT to enhance design education is reliant on fundamental changes within traditional academic culture.

title	Relation-Based Groupware For Heterogeneous Design Teams
source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 86-91
doi	https://doi.org/10.52842/conf.ecaade.2001.086
summary	This paper describes a work about coordination of concurrent engineering in the building construction and design. More particularly it describes the coordination of project teams which are heterogeneous and short-lived. The French context of the building trade is at present characterized by an increase of the quality requirements and by a reduction of the conception and realization delays. This induces the building sector to look for new modes of cooperation as they already exist in industry and services. With a few exceptions, the concurrent engineering tools taken from these sectors are not used in building projects. We make the assumption that the lack of use of these tools is due to the non-fitting of the common existing tools to the specificities of our sector. The solution we propose give a relational vision of the cooperation and the interactions existing during the processes of conception-construction in architectural works. Our first interest point concerns the representation of the actors, the documents and the assignments as a relational network and not as a hierarchical tree, mostly used in the groupware tools. In a second point, we use this relational network to produce a graphic and dynamic representation of the projects. The goal of this method is to reinforce the co-operation and the group awareness by supplying to the actors a good vision of the project evolution in order to increase the conception quality.

summary	The theme, which preceded my knowledge of ACADIA’s true age, resulted from a realization regarding the development and current state of CAD in Research, Education, and Practice. While I only got involved with ACADIA in the last half of its current life to date, I had the honor of studying with some of the early pioneers of CAD: 1) Harold Borkin, a founding member of ACADIA, 2) Jim Turner, a longtime ACADIAn, and a past ACADIA Conference organizer (actually the very first conference I attended), and 3) Ted Hall, another longtime ACADIAn. What I have learned from conversations with them and later witnessed for myself is a fundamental shift of focus in CAD from building tools to using tools. That is, while early CAD students, including myself, used to learn how to create software and tools to solve a particular problem, the current focus in the majority of schools that include a CAD component in their curriculum is on teaching the use of commercial software and/or the use of digital media in the design studio. One need only take a look at old list of courses that used to be offered in the CAD area and compare it with a new list to see this shift. Yet, one form of tool building that is continuing in a significant number of schools is the creation of scripts or small software modules (usually built using a visual editor) to create interactive systems for delivery over the web or on CD-ROM. Examples include the use of Macromedia Director or Flash for creating interactive digital titles. While this current state of affairs has increased the receptivity to digital tools and media, it does obscure an important fact. For knowledge to advance in this area, we need researchers who can not only use tools, but also invent new ones to solve new problems that are not addressed by the existing crop of commercial software. The more time we spend not educating our students in the art and science of building digital tools, the harder it will be to: 1) find teachers in the future with those skills, 2) advance and influence the development of the state-of-the-art in CAD, and 3) erase the use of CAD as a euphemism for slick computer-generated imagery. While not common, the tradition of tool building is still going on most notably in architecture schools with strong financial resources and those that offer doctoral level education. Commercial, governmental and business/education entities are also continuing the research tradition of tool building. ACADIA, as a reflection of the field it focuses on, has widened its scope to solicit papers that deal with CAD education and the use of CAD in practice. Thus, you will read in this book papers that focus on all three aspects: research, education, and practice and in some cases the intersection of two or more of those areas. Thankfully, ACADIA, while concerned with CAD in education has maintained its receptivity to basic research papers as well as a willingness to publish innovative papers in the area of practice. As chair of the technical committee, I made sure that the call for papers and the final selection reflects this desire. We should continue to emphasize the need for presenting this diversity of work in our annual conferences and I am optimistic that the ACADIA community is in support of this notion.

title	XML for Flexibility an Extensibility of Design Information Models

summary	The VR-DIS research programme aims at the development of a Virtual Reality – Design Information System. This is a design and decision support system for collaborative design that provides a VR interface for the interaction with both the geometric representation of a design and the non-geometric information concerning the design throughout the design process. The major part of the research programme focuses on early stages of design. The programme is carried out by a large number of researchers from a variety of disciplines in the domain of construction and architecture, including architectural design, building physics, structural design, construction management, etc.Management of design information is at the core of this design and decision support system. Much effort in the development of the system has been and still is dedicated to the underlying theory for information management and its implementation in an Application Programming Interface (API) that the various modules of the system use. The theory is based on a so-called Feature-based modelling approach and is described in the PhD thesis by [first author, 1999] and in [first author et al., 2000a]. This information modelling approach provides three major capabilities: (1) it allows for extensibility of conceptual schemas, which is used to enable a designer to define new typologies to model with; (2) it supports sharing of conceptual schemas, called type-libraries; and (3) it provides a high level of flexibility that offers the designer the opportunity to easily reuse design information and to model information constructs that are not foreseen in any existing typologies. The latter aspect involves the capability to expand information entities in a model with relationships and properties that are not typologically defined but applicable to a particular design situation only; this helps the designer to represent the actual design concepts more accurately.The functional design of the information modelling system is based on a three-layered framework. In the bottom layer, the actual design data is stored in so-called Feature Instances. The middle layer defines the typologies of these instances in so-called Feature Types. The top layer is called the meta-layer because it provides the class definitions for both the Types layer and the Instances layer; both Feature Types and Feature Instances are objects of the classes defined in the top layer. This top layer ensures that types can be defined on the fly and that instances can be created from these types, as well as expanded with non-typological properties and relationships while still conforming to the information structures laid out in the meta-layer.The VR-DIS system consists of a growing number of modules for different kinds of functionality in relation with the design task. These modules access the design information through the API that implements the meta-layer of the framework. This API has previously been implemented using an Object-Oriented Database (OODB), but this implementation had a number of disadvantages. The dependency of the OODB, a commercial software library, was considered the most problematic. Not only are licenses of the OODB library rather expensive, also the fact that this library is not common technology that can easily be shared among a wide range of applications, including existing applications, reduces its suitability for a system with the aforementioned specifications. In addition, the OODB approach required a relatively large effort to implement the desired functionality. It lacked adequate support to generate unique identifications for worldwide information sources that were understandable for human interpretation. This strongly limited the capabilities of the system to share conceptual schemas.The approach that is currently being implemented for the core of the VR-DIS system is based on eXtensible Markup Language (XML). Rather than implementing the meta-layer of the framework into classes of Feature Types and Feature Instances, this level of meta-definitions is provided in a document type definition (DTD). The DTD is complemented with a set of rules that are implemented into a parser API, based on the Document Object Model (DOM). The advantages of the XML approach for the modelling framework are immediate. Type-libraries distributed through Internet are now supported through the mechanisms of namespaces and XLink. The implementation of the API is no longer dependent of a particular database system. This provides much more flexibility in the implementation of the various modules of the VR-DIS system. Being based on the (supposed to become) standard of XML the implementation is much more versatile in its future usage, specifically in a distributed, Internet-based environment.These immediate advantages of the XML approach opened the door to a wide range of applications that are and will be developed on top of the VR-DIS core. Examples of these are the VR-based 3D sketching module [VR-DIS ref., 2000]; the VR-based information-modelling tool that allows the management and manipulation of information models for design in a VR environment [VR-DIS ref., 2000]; and a design-knowledge capturing module that is now under development [first author et al., 2000a and 2000b]. The latter module aims to assist the designer in the recognition and utilisation of existing and new typologies in a design situation. The replacement of the OODB implementation of the API by the XML implementation enables these modules to use distributed Feature databases through Internet, without many changes to their own code, and without the loss of the flexibility and extensibility of conceptual schemas that are implemented as part of the API. Research in the near future will result in Internet-based applications that support designers in the utilisation of distributed libraries of product-information, design-knowledge, case-bases, etc.The paper roughly follows the outline of the abstract, starting with an introduction to the VR-DIS project, its objectives, and the developed theory of the Feature-modelling framework that forms the core of it. It briefly discusses the necessity of schema evolution, flexibility and extensibility of conceptual schemas, and how these capabilities have been addressed in the framework. The major part of the paper describes how the previously mentioned aspects of the framework are implemented in the XML-based approach, providing details on the so-called meta-layer, its definition in the DTD, and the parser rules that complement it. The impact of the XML approach on the functionality of the VR-DIS modules and the system as a whole is demonstrated by a discussion of these modules and scenarios of their usage for design tasks. The paper is concluded with an overview of future work on the sharing of Internet-based design information and design knowledge.

source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 139-149
summary	The lure of virtual environments is strong and the apparent potential is enticing. But questions of how Human Computer Interaction (HCI) issues should be handled and married with best practice in Human-Human Interaction (HHI) remains largely unresolved. How should architectural images and ideas be most appropriately represented, and how should designers interact and react through this computer mediated medium? Whilst there is never likely to be unanimity in answer to such questions, we can develop new ideas and new systems, test them, report on them and invite comment. The nature and novelty of virtual environments is such that refinements and innovations are likely to come from a variety of sources and in a variety of ways. The work described here explains the evolution and current plans for the development of a particular approach that has been developed and refined by the authors. Low-cost, effective and appropriate are the key words that have driven the developments behind the evolving nAVRgate system that has arisen from this work, and that is described here.

summary	The context and long term goal of the project is to develop design environments in which the computer becomes an active and creative partner in the design process. To try to set-up a system that would enhance the design process by suggesting possibilities, has been preferredto an approach that emphasises optimisation and problem-solving.The work develops around the general concept of morphogenesis, the process of development of a system's form or structure. Besides the obvious example of embryological growth, biological evolution, learning, and societal development can also be considered as morphogenetic processes.The aim is to set a foundation from where latter work can develop in the study of how form unravels, and the implications and possibilities of the utilisation of such processes in design. Some basic principles are established, regarding the idea of Ontogenesis, the study of thedevelopment of organisms, and Epigenesis, the mode Ontogenesis operates.Drawing on D’Arcy Thompson’s ideas and inspired on the models and approaches developed in the recent field of Artificial Life, this work explores the possibilities of using a model based in bone accretion to develop structural systems. The mechanisms by which bone is able toadapt are relatively known and simple, and at the same time they address a sensible problem, such as it is the case of the static performance of a structure. This may seem contradictory with what was mentioned above regarding problem solving. The problem is anyway approached not with the intention of finding optimal solutions, but challenging and creativeones. It is not answers the computer should provide, but questions about the problematic of the design. It is in this context of “problem-worrying” (as opposed to problem solving) that the work has been carried.

title	Past, Present, and Future of User Interface Software Tools
source	Carroll, J. (eds), Human-Computer Interaction in the New Millennium, Addison Wesley, ACM Press, New York, pp. 213–233
summary	A user interface software tool helps developers design and implement the user interface. Research on past tools has had enormous impact on today's developers-virtually all applications today were built using some form of user interface tool. In this paper, we consider cases of both success and failure in past user interface tools. From these cases we extract a set of themes which can serve as lessons for future work. Using these themes, past tools can be characterized by what aspects of the user interface they addressed, their threshold and ceiling, what path of least resistance they offer, how predictable they are to use, and whether they addressed a target that became irrelevant. We believe the lessons of these past themes are particularly important now, because increasingly rapid technological changes are likely to significantly change user interfaces. We are at the dawn of an era where user interfaces are about to break out of the "desktop" box where they have been stuck for the past 15 years. The next millenium will open with an increasing diversity of user interfaces on an increasing diversity of computerized devices. These devices include hand-held personal digital assistants (PDAs), cell phones, pagers, computerized pens, computerized notepads, and various kinds of desk, and wall-size computers, as well as devices in everyday objects (such as mounted on refrigerators, or even embedded in truck tires). The increased connectivity of computers, initially evidenced by the World-Wide Web, but spreading also with technologies such as personal-area networks, will also have a profound effect on the user interface to computers. Another important force will be recognitionbased user interfaces, especially speech, and camera-based vision systems. Other changes we see are an increasing need for 3D and end-user customization, programming, and scripting. All of these changes will require significant support from the underlying user interface software tools.

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.

summary	A great part of our physical environment and existence is currently undergoing an epochal transformation from a solid to a liquid state on many layers of technological evolution. Optical phenomena and radical shifts in visuality, particularly manifest through media propagation are impacting on urban space in unpredictable ways. City - space is not only perceived as a physical place but also simultaneously inhabited as a virtual site. Both conditions form the hybrid of an urban realm, construed as surveillance, simulation, distraction and a relentless proliferation of information. Ultimately, all man-machine interfaces of hardware will be adequately infinitely machined. This process however will continue beyond the now experienced level of TV, video, cellular-phones and computers, incorporating interconnected surfaces of text, music and other kind of data. The surrounding sensorium will penetrate the phenomenological tissue of our nervous system to the extent that we are unconsciously fluidly interacting. Behavioral properties of matter and their smooth transmittal of visual, sound and tactile sensations, will provide an intellectual and sensual presence which renders space and its perception as being liquefied. Also the interrelation between the exterior and interior usage will be smooth and multidimensional, as the building’s envelopes are capable to alter their properties in response to contextual changes or movements. A redefinition of the disciplines of architecture and urban planning responds to the changes in cultural, social, political and economical milieus.

summary	The textile surface is a support to express symbolically trought the sings repetition our cultural diversity. Into the frame of a workshop, we propose ourself to review our didactic topics to generate a new teaching- lerarning strategy to the Textile Design. We put forward to take “fragments” of this cultutal diversity, to make it autonomous and starting from it occasional profile because of the whole break, to recognize the geometry and language itself, the interrupted connections, to be allowed to overflow and, in a symbiosis with the new digital medias, to generate a new speech of identity in textile design.

summary	The advent of the Internet has opened up and given, particularly, the developing countries and the world in general, a transformation into collective intelligence (Levy, 1998) societies linked to digital communication (Rafi, 2001). Apart from large corporations, the rapid evolution of border-less communication has also synergise between the art and science expertise to form low-cost internet-based networks that have become multi-million dollar companies within a short period of time (e.g. Linux) (Rafi, 2001). In the context of architectural designs and construction industries, the birth of Internet-based CAD (iCAD) solutions has offered a new dimension to architectural practice. The function of CAD has expanded as a tool to communicate and collaborate as well as to better control all phases of the architectural practices. This paper will review the current available iCAD tools and explore the possible utilisation of iCAD in architectural practices. The opportunities for modifying current professional practice standards to best use iCAD will be rationalised as well as the elements in ensuring the effectiveness of iCAD implementation. The final component of the paper will be an evaluation framework to measure the value of iCAD in an architectural practice. The framework will become an early platform for an architectural practice to decide and plan their future in utilising and applying iCAD in the most efficient way.

title	Function-to-form mapping: model, representation and applications in design synthesis
source	Computer-Aided Design, Vol. 33 (10) (2001) pp. 699-719
summary	Design of a new artifact begins with incomplete knowledge about the final product and the design evolves as it progresses from the conceptual design stage to a moredetailed design. In this paper, an effort has been made to give a structural framework, through a set of generic definitions, to product specification, functionalrepresentation, artifact representation, artifact behavior and tolerance representation. A design synthesis process has been proposed for evolution of a product from theproduct specification. The proposed design synthesis method is a mapping from the functional requirements to artifacts, with multi-stage constrained optimization duringstages of design evolution. Provisions have been kept to augment and/or modify the product specification and domain knowledge during stages of development to guidethe design process. The effectiveness of the proposed design process has been illustrated with a simple design example based on a sample artifact library. An overalldesign scheme has been presented.
