title The Art of Emergence
source International Conference on Generative Art
summary Since several years, the term emergence is mentioned in the paradigm of chaos and complexity. Following this approach, complex system constituted by multitude of individual develop global behavioral properties on the base of local chaotic interactions (self-organization). These theories, developed in scientific and philosophical milieus are rapidly spreading as a "way of thinking" in the several fields of cognitive activities. According to this "way of thinking" it is possible revise some fundamental themes as the economic systems, the cultural systems, the scientific paths, the communication nets under a new approach where nothing is pre-determined, but the global evolution is determined by specific mechanisms of interaction and fundamental events (bifurcation). With a jump in scale of the life, also other basic concepts related to the individuals as intelligence, consciousness, psyche can be revised as self-organizing phenomena. Such a conceptual fertility has been the base for the revision of the artistic activities as flexible instruments for the investigation of imaginary worlds, metaphor of related real worlds. In this sense we claim to the artist a role of "researcher". Through the free exploration of new concepts, he can evoke qualities, configurations and hypothesis which have an esthetical and expressive value and in the most significant cases, they can induce nucleation of cultural and scientific bifurcation. Our vision of the art-science relation is of cooperative type instead of the conflict of the past decades. In this paper we describe some of the most significant realized artworks in order to make explicit the concepts and basic themes. One of the fundamental topics is the way to generate and think to the artwork. Our characterization is to see the artwork not as a static finished product, but as an instance or a dynamic sequence of instances of a creative process which continuously evolves. In this sense, the attention is focused on the "generative idea" which constitutes the envelop of the artworks generable by the process. In this approach the role of technology (computers, synthesizers) is fundamental to create the dimension of the generative environment. Another characterizing aspect of our artworks is derived by the previous approach and specifically related to the interactive installations. The classical relation between artist, artwork and observers is viewed as an unidirectional flux of messages from the artist to the observer through the artwork. In our approach artist, artwork and observer are autonomous entities provided with own personality which jointly intervene to determine the creative paths. The artist which generate the environment in not longer the "owner" of the artwork; simply he dialectically bring the generative environment (provided by a certain degree of autonomy) towards cultural and creative "void" spaces (not still discovered). The observers start from these platforms to generate other creative paths, sometimes absolutely unexpected , developing their new dialectical relations with the artwork itself. The results derived by these positions characterize the expressive elements of the artworks (images, sequences and sounds) as the outcomes of emergent behavior or dynamics both in the sense of esthetical shapes emergent from fertile generative environments, either in terms of emergent relations between artist, artwork and observer, either in terms of concepts which emerge by the metaphor of artificial worlds to produce imaginary hypothesis for the real worlds.

summary Understanding the dominant ethos of our age is imperative but not easy. However it is quite evident that new technologies have altered our times. Every discipline is now forced to be critical in developing new concepts according to the realities of our times. Implementing a critical worldview and consciousness is now more essential than ever. Latest changes in information technology are creating pressure on change both in societal and cultural terms. With its direct relation to these technologies, computer aided architectural design education, is obviously an outstanding / prominent case within contemporary debate. This paper aims to name some critical points related to computer aided architectural design education (CAADE) from the perspective of critical communication studies and critical education theories. It tries to relate these three areas, by introducing their common concepts to each other. In this way, it hopes to open a path for a language of critique. A critique that supports and promotes experimentation, negotiation, creativity, social consciousness and active participation in architectural education in general, and CAADE in specific. It suggests that CAADE might become critical and produce meta-discourses [1 ] in two ways. Firstly, by being critical about the context it exists in, that is to say, its relationships to the existing institutional and social structures and secondly by being critical about the content it handles; in other words by questioning its ideological dimensions. This study considers that analysing the role of CAADE in this scheme can provide architectural education with the opportunity to make healthy projections for the future.

summary The topic of this paper is to describe the ability of 3D CAD systems to integrate designers and engineers into a simultaneous process developing a functional and aesthetic concept in a close and equal interdisciplinary process. We already have the Finite Element Method, FEM systems for analyzing the mechanical behavior of constructions. This technique is suitable for justifying design aspects in the final part of the design process. A new group of CAE systems under the generic term Topology optimizing has the potentials to handle aspects of conceptual design and aesthetic criteria. Such interactive design tools do not eliminate the designer, but the relationship between the designer and other professions and the professional consciousness of the designer will change. It is necessary to develop common ideas able to connect the scientific and the artistic fields. The common aesthetic values must be clarified and the corresponding formal ideas be developed. These tools could be called "Construction tools for the intelligent user" (Olhoff, 1998) because the use of optimizing is based on a profound knowledge of the techniques.

title Do Intelligent Objects Need Programmed Users?
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 52-55
summary Intelligent objects for daily use offer greater advantages than electromechanical products. However, they need a user whose life is more methodical, programmed and predictable. As de number of services offered in such products increase, their restrictions in their flexibility of use arise. Finally, users adapt themselves to habits that these objects suggest (for better) or prescribe (for worse). However, a paradox exists. What is controversial for a standard user: the increasing passivity justified in the eternal pursuit of comfort, for a disabled person means achieving independence and autonomy. In order to accomplish the revolutionary equity that computer science claims, the possibility of being excluded for economic reasons should not exist. If not, it will increase the fracture between coexistent realities in the same territory. For these reasons, assuming the risk of being considered naive and idealist, we believe that in order to build a better future it is necessary to promote policies that guarantee the access to new technologies for people with low economic means. Together with the consciousness users gain -related to product selection-, it would break the premature discouragement that the markets try to impose, resigning us to an unjustified idea of weakness and submission.

title Artistic Process, Cybernetics of Self and the Epistemology of Digital Technology
source International Conference on Generative Art
summary From the viewpoint of Batesonian cybernetics, ‘conscious purpose’ and artistic process are distinct ends of a spectrum of the functioning of self. Artistic activities— by which I mean art, poetry, play, design, etc.— involve processes that are beneath the stratum of consciousness. By definition, consciousness is selective awareness and is linear in execution and limited in its capability to synthesize complex parameters. As Heidegger pointed out, technology is a special form of knowledge (episteme). A machine is a manifestation of such a knowledge. A machine is a result of conscious purpose and is normally task-driven to accomplish a specific purpose(s). The questions this paper raises are to do with the connections between conscious purpose, artistic process and digital technology. One of the central questions of the paper is "if artistic process requires an abandonment or relinquishment of conscious purpose at the time of the generation of the work of art, and if the artistic process is a result of vast number of ‘unconscious’ forces and impulses, then could we say that the computer would ever be able to ‘generate’ or ‘create’ a work of art?" In what capacity and what role would the computer be a part of the generative process of art? Would a computer be able to ‘generate’ and ‘know’ a work of art, which, according to Bateson, requires the abandonment of conscious purpose? The ultimate goal of the paper is to unearth and examine the potential of the computers to be a part of the generative process of what Bateson has called "total self as a cybernetic model". On another plane of discourse, Deleuze and Guattari have added a critical dimension to the discourse of cybernetics and models of human mind and the global computer networks. Their notion of ‘rhizome’ has its roots in Batesonian cybernetics and the cybernetic couplings between the ‘complex systems’ such as human mind, biological and computational systems. Deleuze and Guattari call such systems as human brain and the neural networks as rhizomatic. Given the fact that the computer is the first known cybernetic machine to lay claims to artificial intelligence, the aforementioned questions become even more significant. The paper will explore how, cybernetically, the computer could be ‘coupled’ with ‘self’ and the artistic process — the ultimate expression of human condition. These philosophical and artistic explorations will take place through a series of generative artistic projects (See the figure below for an example) that aim at understanding the couplings and ‘ecology’ of digital technology and the cybernetics of self.

title Integrating energy consciousness in the design process
source Automation in Construction 8 (4) (1999) pp. 463-472
summary The design process for an intelligent, energy conscious building which was built, along with the design tools that were applied, is presented. The building, situated in the hot–humid climate of Rehovot, Israel, houses the laboratories and offices of the Weizmann Institute's Environmental Science and Energy Research Department. Alternative bio-climatic design options were proposed and evaluated throughout the detailed design stage. A building energy performance index (BEPI) was established for each alternative. This index reflects the total amount of energy consumption for heating, cooling, ventilating and lighting used per square meter of floor area. Thermal modeling for the different design alternatives were carried out by means of an hourly dynamic simulation model. The model solves simultaneously the heat transfer equations through all exterior walls, taking into account the thermal mass of each external wall as well as internal partitions. The model was extended to include hourly calculations of daylighting and geometrical shading coefficient of the windows, as well as automated and `smart' control strategies.

doi https://doi.org/10.52842/conf.ecaade.1999.196
summary The study of a cyberuniversity derives from an analogy between real urban space and its virtual "substitution". It represents an attempt to balance some views, which seems to be contrary, exclusive, but they are just parts of the same wholeness. Especially the notion of a cyber society is lately considered such an exaggeration, that it is possible to forget the meaning of a real life experience and interactions, which are already threatened. One should contribute to the awarness that is used in such a comparison, it is "just" an analogy, not a real similarity. At the same time it is possible to point out some limitations of a cyberspace and indicate a more realistic view of the meaning of cyber communities. Awarness of the development processes could help to find a balance between reality and virtuality, using cyberfacilities not to destroy us (our identity) but to improve the quality of our (real) life.

title APPLICATION OF SPATIAL DESIGN ABILITY IN A POSTGRADUATE COURSE
source Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 75-82
summary Spatial Design Ability (SDA) has been defined by the author (1983) as the capacity to anticipate the effects (psychological impressions) that architectural spaces or its components produce in observers or users. This concept, which requires the evaluation of spaces by the people that uses it, was proposed as a guideline to a Masters Degree Course in Architectural Design at the Universidad Autonoma de Aguascalientes in Mexico. The theory and the exercises required for the experience needed a model that could simulate spaces in terms of all the variables involved. Full-scale modeling as has been tested in previous research, offered the most effective mean to experiment with space. A simple, primitive model was designed and built: an articulated ceiling that allows variation in height and shape, and a series of wooden panels for the walls and structure. Several exercises were carried out, mainly to experience cause -effect relationships between space and the psychological impressions they produce. Students researched into spatial taxonomy, intentional sequences of space and spatial character. Results showed that students achieved the expected anticipation of space and that full-scale modeling, even with a simple model, proved to be an effective tool for this purpose. The low cost of the model and the short time it took to be built, opens an important possibility for Institutions involved in architectural studies, both as a research and as a learning tool.

title Automated Cost Analysis of Concept Design BIM Models

summary AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

summary Since 1991 Virtual Reality has been used in student projects in the Building Information Technology group. It started as an experimental tool to assess the impact of VR technology in design, using the environment of the associated Calibre Institute. The technology was further developed in Calibre to become an important presentation tool for assessing design variants and final design solutions. However, it was only sporadically used in student projects. A major shift occurred in 1997 with a number of student projects in which various computer technologies including VR were used in the whole of the design process. In 1998, the new Design Systems group started a design studio with the explicit aim to integrate VR in the whole design process. The teaching effort was combined with the research program that investigates VR as a design support environment. This has lead to increasing number of innovative student projects. The paper describes the context and history of VR in Eindhoven and presents the current set-UP of the studio. It discusses the impact of the technology on the design process and outlines pedagogical issues in the studio work.

source AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 327-335
summary The Design Systems group of the Eindhoven University of Technology started a new kind of design studio teaching. With the use of high-end equipment, students use Virtual Reality from the very start of the design process. Virtual Reality technology up to now was primarily used for giving presentations. We use the same technology in the design process itself by means of reducing the time span in which one gets results in Virtual Reality. The method is based on a very brief cycle of modelling in AutoCAD, assigning materials in 3DStudio Viz, and then making a walkthrough in Virtual Reality in a standard landscape. Due to this cycle, which takes about 15 seconds, the student gets immediate feedback on design decisions which facilitates evaluation of the design in three dimensions much faster than usual. Usually the learning curve of this kind of software is quite steep, but with the use of templates the number of required steps to achieve results is reduced significantly. In this way, the potential of Virtual Reality is not only explored in research projects, but also in education. This paper discusses the general set-up of the design studio and shows how, via short workshops, students acquire knowledge of the cycle in a short time. The paper focuses on the added value of using Virtual Reality technology in this manner: improved spatial reasoning, translation from two-dimensional to three-dimensional representations, and VR feedback on design decisions. It discusses the needs for new design representations in this design environment, and shows how fast feedback in Virtual Reality can improve the spatial design at an early stage of the design process.

summary The VR-DIS project aims to provide design support in the early design stage using a Virtual Reality environment. The initial brief of the design system is based on an analysis of a design case. The paper describes the process of analysis and extraction of design knowledge and design concepts in terms of Features. It is demonstrated how the analysis has lead to a classification of design concepts. This classification forms one of the main specifications for the VR-based design aid system that is being developed in the VR-DIS programme. The paper concludes by discussing the particular approach used in the case analysis and discusses future work in the VR-DIS research programme.

Building on these projects, we present a novel and transferable process for the robotic fabrication of bespoke timber subassemblies made of off-the-shelf standard timber elements. A nonstandard timber structure (Figure 2), consisting of four bespoke subassemblies: three vertical supports and a Zollinger (Allen 1999) roof structure, acts as the case study for the research and validates the feasibility of the proposed process.

summary How and when should CAAD be introduced in the curriculum of the School of Architecture? This paper begins with some arguments for starting CAAD education at the very beginning. At the School of Architecture in Lund teachers in the first year courses have tried to integrate CAAD with the introduction to architectural concepts and techniques. Traditionally the first year is divided by several subjects running courses separatly without any contact for coordination. From the academic year 96/97 the teachers of Aplied aestetics, Building Science, Architectural design and CAAD have decided to colaborate as much as possible to make the role of our different fields as clear as possible to the students. Therefore integrating CAAD was a natural step in the academic year 98/99. The computer techniques were taught one step in advance so that the students can practise their understanding of the programs in their tasks in the other subjects. The results were surprisingly good! The students have quickly learned to mix the manual and computer techniques to make expressive and interesting visual presentations of their ideas. Some students with antipaty to computers have overcome this handicap. Some interesting observations are discussed.

summary Although recent technology in time-based representation has vastly improved, animation in virtual prototype design field remains the same. Some designers invest a huge amount of money in the latest visualisation and multimedia technology and yet may create even worse animation. They often cramp sequences resulting in many viewers failing to interpret the design positively as they miss a lot of vital information that explains the design. This paper basically reports the importance of film-making understanding for producing good virtual prototype animation. It will be based on a part of a research project on the use of time-based media in architectural practices. It also includes an empirical analysis of several architectural-based documentary films (including an interview with the film director) and past and present computer animation. This paper then concludes with recommendations of good techniques for making animated visualisation relative to the stage at which the animation is produced for better design decision.

summary The paper describes an algorithm for constructing the topology from a set of line segments or polylines. The problem appears for example at land-maps that have been drawnby general-purpose drawing packages or captured from blue-prints by digitalisation. The solution comprises two steps; in the first step inconsistencies in the input data aredetected and removed, and in the second step the topology is constructed. The algorithm for topology construction consists of two phases: determination of a concave hull,and generation of polygons. It is shown that the running-time of the presented algorithm is better than O(n2), where n is the number of input points. Because of a largenumber of geometric elements being expected, the geometric search needed at the first step of the algorithm is speeded up by an acceleration techniquea uniform planesubdivision.

summary The bridge deck has a apparent simple shape, but it is the result of an adequate combination of two longitudinal geometric components: the deck shape evolution along de longitudinal section the layout of the road, that acts in simultaneous over a cross section, defining the deck exact shape. A geometric modelling computer programme was developed for box girder decks, allowing the generation of cross sections along the deck, defined with correct shape and location. In the elaboration of the deck plan drawings, the geometric information of the real deck shape is required. This information is not managed in an integrated and automatic way. On the creation of these drawings, directly executed over a graphic system, the time consumed is considerable and it is easy to comet errors. This paper describes the drawing module included in the computer program refereed. The deck plan projections are obtained, in DXF format drawing files, using the geometric information obtained from 3D-deck model. Using the drawing module it is possible to generate the usual deck drawings required in bridge design process. Then, his module is a great support for the design process within its geometric design stage.

summary Introduction: virtual reality in architecture Virtual Reality (VR) is an emergent computer technology for full 3D-simulations, which has a natural application in the architectural work, due that activity involves the complete definition of buildings prior to its construction. Although the profession has a long tradition and expertise in the use of 2D-plans for the design of buildings, the increasing complexity of projects and social participation requires better media of representation. However, the technological promise of Virtual Reality involves many sophisticated software and hardware developments. It is based on techniques of 3D-modelling currently incorporated in the majority of drawing software used in architecture, and also there are several tools for rendering, animation and panoramic views, which provide visual realism. But other capabilities like interactivity and sense of immersion are still complex, expensive and under research. These require stereoscopic helmets, 3D pointers and trackers with complicated configurations and uncomfortable use. Most advanced installations of Virtual-Reality like CAVEs involve much hardware, building space and restrictions for users. Nevertheless, diverse developers are working in Virtual-Reality user-friendly techniques and there are many initial experiences of architectural walk-throughs showing advantages in the communication and development of designs. Then we may expect an increasing use of Virtual Reality in architecture.
