title	The use of genetic programming for applications in the field of spatial composition
source	International Conference on Generative Art
summary	Architectural design teaching using computers has been a preoccupation of CECA since 1991. All design tutors provide their students with a set of models and ways to form, and we have explored a set of approaches including cellular automata, genetic programming ,agent based modelling and shape grammars as additional tools with which to explore architectural ( and architectonic) ideas.This paper discusses the use of genetic programming (G.P.) for applications in the field of spatial composition. CECA has been developing the use of Genetic Programming for some time ( see references ) and has covered the evolution of L-Systems production rules( coates 1997, 1999b), and the evolution of generative grammars of form (Coates 1998 1999a). The G.P. was used to generate three-dimensional spatial forms from a set of geometrical structures .The approach uses genetic programming with a Genetic Library (G.Lib) .G.P. provides a way to genetically breed a computer program to solve a problem.G. Lib. enables genetic programming to define potentially useful subroutines dynamically during a run .* Exploring a shape grammar consisting of simple solid primitives and transformations. * Applying a simple fitness function to the solid breeding G.P.* Exploring a shape grammar of composite surface objects. * Developing grammarsfor existing buildings, and creating hybrids. * Exploring the shape grammar of abuilding within a G.P.We will report on new work using a range of different morphologies ( boolean operations, surface operations and grammars of style ) and describe the use of objective functions ( natural selection) and the "eyeball test" ( artificial selection) as ways of controlling and exploring the design spaces thus defined.

summary	This paper shows the content of a subject imparted at the ETSAB (UPC). It describes the use of CAD systems in tasks that could not even be thought before new technology arrival and traditional methods had to be used. CAD systems potential to simultaneously work with constitutive objects and relations between them is taken into advantage. The definite design is not only the juxtaposition of some but the tight relation linking them. This work proposes CAD systems to be used in architectural design projects as spreadsheets to perform arithmetic calculations. The process to obtain an architectural model has ended in a logic sequence of formal operations, which uses completely defined objects as data. Any element of the project, data or operation, can be changed and model updating is automatically performed obtaining the new result. Finally a concrete exercise developed along the course is shown like a practical example.

summary	The web is a vital element for realising the AVOCAAD project. The web's features and functionality present a splendid platform. The following will discuss multiple advantageous options available through this new media as they relate to the AVOCAAD project. All data are permanently available on a central server, accessible to an unlimited number of clients anytime, anywhere in the world. Clients access the centrally stored information and work locally with the material, thus using the common server-to-client publishing set-up. Dynamic database functions available to the general user are able to control various aspects of data flow. This procedure is used by the AVOCAAD-web-system. Recent developments in the web are going to enable an even more sophisticated use, thus widening the range of application. The online material may present interactive properties, meaning that the user is able to observe changes of processes in relation to the influence he actually exerts on the material within his subsystem. We will focus on this material in our paper, exploring the possible impact on AVOCAAD-exercise.

summary	Evolution, said Julian Huxley, is in three different sectors. The first is organic - the cosmic process of matter. The second is biological - the evolution of plants and animals. The third is psychological and is the development of man's cultures. It is this third stage that is now critical, and if we are to survive as a species it can only be by replacing nature's controls by our own, not only birth control but our use of the whole environment.

title	Design Navigation and Construction Simulation by Virtual Reality
source	CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 31-41
doi	https://doi.org/10.52842/conf.caadria.1999.031
summary	This paper depicts the approach of constructing a virtual reality environment for simulating architectural design and construction operations. The virtual environment is established to demonstrate the spatial performance of design and constructability of construction operations. Particularly, the functions such as navigation of construction sites, simulation of construction operations, and evaluation of construction details will be critical to construction operations. The system shell is implemented by JAVA on the web and integrated with VRML for supporting the above functions. The study focuses on the needs for the system integration and interface design. Four modes of human computer interfaces are proposed, including the user, agent, monitor, and immersion modes. Finally, this paper provides demonstration of construction simulation in an office building project to highlight the above discussion. The operations of crane towers and curtain wall installation are also studied in the construction process. In conclusion, this paper demonstrates the potential uses and limitation of virtual reality in simulation of the built environment.

source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 365-380
summary	Intemet technologies provide opportunities for improving the delivery of facility information to building owners and operators. Discussions with facility operators have led to identification of problems in current practices of delivering facility information using as-built drawings. A Web-based software prototype illustrates how facility information can be automatically structured into documents that support specific facility operations tasks.

summary	This paper treats of the management of the position of objects on the plane. At first sight problems related with planning objects on the plane appear to be quite trivial. Nevertheless a system able to manage the permutation of objects the one with respect to the others becomes a complex one when all the possible variations are taken into account. The operations to be performed include topological variations in a combinatorial process. Although the results of such a system could be of general design application in this paper only architectural problems are examined as examples. In the first part an outline of the system is presented. In the second part a computer program directed to produce graphical results is described together with some case studies.

title	A proposed system for integrating design and production in the precast building industry
source	The Int. Journal of Construction IT 7(1), pp. 72-83
summary	The UK construction industry is going through a major re-appraisal, with the objective of reducing construction costs by at least 30% by the end of the millennium. Precast and off-site construction are set to play a major role in improving construction productivity, reducing costs and improving working conditions. In a survey of current practices in the prefabrication industry, it was concluded that the industry is far behind other manufacturing-based industries in terms of the utilisation of IT in production planning and scheduling and other technical and managerial operations. It is suggested that a systematic, integrated, computer-aided, approach to presenting and processing information is needed. The objective of this paper is to introduce and discuss the specifications of an integrated intelligent computer-based information system for the precast concrete industry. The system should facilitate: the integration of design and manufacturing operations; automatic generation of production schedules directly from design data and factory attributes; and generation of erection schedules from site information, factory attributes and design data. It is hypothesised that the introduction of such a system would reduce the total cost of precasting by 10% and encourage clients to choose precast components more often.

summary	In 1995 the programming of a specialized, expert graphic software CA-TSD, began. The TSD acronym designates a graphic language derived from the theory of spatial delimitation, it systematizes all possibilities of selection and combination of flat and volumetric figures. It establishes necessary and sufficient morphic and tactic dimensions to account for all possible relationships of selection and combination. TSD proposes a syntactic reading of those formal, pure design operations underlying traditional representations. Tracings and complex configurations described by tree-hierarchical structures of simple configurations allow for a coherent syntactic analysis of the design structure of any object this will allow the construction of a pure design formula for the conscious and unconscious prefiguration operations of an artist or style in this presentation, we will use our proprietary CA-TSD software that will allow for fast verification of what's stated, including architecture and graphic design examples.

title	About Objects and Approaches - A Conceptual View on Building Models
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 133-148
summary	Considering integrated CAAD environments for architectural design, a number of different approaches are possible. This paper presents the policy of the CADLAB at the KU Leuven University, where design support right from the first design phases is a basic consideration. After a short introduction on the theoretical framework and additional design tests, we will discuss the core object model that forms the cornerstone for the contemplated design environment. This object model describes all possible data, concepts and operations connected with the architectural design process. For its development, we used the object-oriented analysis method MERODE. The starting-points and main aspects of the model will be discussed, illustrated with examples of implemented prototypes. The architect's point of view and the specific nature of the architectural design process were always kept in mind, thus leading to a model that hopes to make a valuable contribution to the research area of integrated design environments.

title	Teddy: A Sketching Interface for 3D Freeform Design
source	SIGGRAPH 99 Conference Proceedings, 109-126. ACM
summary	Teddy is a sketching interface for quickly and easily design freeform models such as stuffed animals and other rotund objects. The user draws several 2D freeform strokes interactively on the screen and the system automatically constructs plausible 3D polygonal surfaces. Our system supports several modeling operations, including the operation to construct a 3D polygonal surface from a 2D silhouette drawn by the user: it inflates the region surrounded by the silhouette making wide area fat, and narrow area thin. Teddy, our prototype system, is implemented as a Java program, and the mesh construction is done in real-time on a standard PC. I will give a live demonstration of modeling operations and describe its algorithms in detail.

title	Toolspaces and Glances: Storing, Accessing, and Retrieving Objects in 3D Desktop Applications
source	Proceedings of the Symposium on Interactive 3D Graphics 1999. pp. 163-168
summary	Users of 3D desktop applications perform tasks that require accessing data storage, moving objects, and navigation. These operations are typically performed using 2D GUI elements or 3D widgets. We wish to focus on interaction with 3D widgets directly in the 3D world, rather than forcing our users to repeatedly switch contexts between 2D and 3D. However, the use of 3D widgets requires a mechanism for storing, accessing, and retrieving these widgets. In this paper we present toolspaces and glances to provide this capability for 3D widgets and other objects in interactive 3D worlds. Toolspaces are storage spaces attached to the user's virtual body; objects placed in these spaces are always accessible yet out of the user's view until needed. Users access these toolspaces to store and retrieve objects through a type of lightweight and ephemeral navigation we call glances.

title	Digital Simulation and Inferential Systems
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 87-92
summary	From the perspective of logic and epistemological formalizations, the processes for data elaboration relate reasoning schemes to inferential operations which enable the building, understanding and setting of criteria for knowledge validation in a complex sequence. Cognitive operations do not belong exclusively to the field of discourse thinking,' they also apply to the field of perception. Specially in the area of images, there exist inferences which are expressed and operated through other media. A particular aspect is the one of digital simulation and the links established with inferential systems. Although they are not the same thing, since simulation is a cognitive methodology, both are based on similar logic principles. It is obviously necessary to build budget or referential frameworks to support practices deriving from the graphic/digital culture. Thus, they could act as judgement instruments in order to analyze and recognize changes in project, space, morphological and expressive paradigms, and to overcome the instrumental and reductionist bias usually found in the development of these practices. The present work is oriented in this direction, studying relations established among digital simulation, inferential systems, cognitive elaboration and scientific knowledge validation. We aim at exploring and researching into the affinity, links and differences between simulation and analogic-abductive inferential systems so as to characterize: 1.) The concept of digital simulation, not only due to its strong reproductive power but to its inherent referential, cognitive and poetic functions. 2.) The nature of replacing actions projected by simulation with respect to reality in order to produce a representative act the innovative and creative power of simulation, directed both to the past and the future. 3.) The dimensions of prevision and interpretation where simulation develops its theoretical and empirical attitudes and the idea that simulation derives from the combination of hypothesis and experimentation.

title	Formal Alternatives Through Ludic Process Applied to Tessellation
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 101-108
summary	The digital graphic systems development is evident during the alternative generation process, especially when the component objects are linked to a geometric base by modulation. In this sense, the tiling modular characteristics are used as geometric support which modulation or internal divisions contain material forms (objects in 3D) immaterial forms (spaces in 3D). That is to say that each tiling module can be projected or not in 3D. The way to do this consists of applying it not only as two-dimensional support but also as operational structure by means of operations of pure translation, in 3D. It is applied to architectural themes which systemic parts or components sectors admit repetitions of units (dwelling buildings, schools, offices, hotels, etc.) in plan floor levels and in elevation as well. When programmatic and morphological requirements are solved groups are organized conforming systems in two or three dimensions. In the alternative generation stage it is tried to avoid conditioning and restrictions developing a ludic process of "piling up tiles" simple concepts stimulating creativity for the production of innovating architectonic forms. Creative ideas can arise from the game playing with 3D forms. This paper attempts to show a manner to generate unusual architectural forms that, otherwise, within a traditional design process might not be found. Some architectural examples developed with this ludic procedure are presented.

source	Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 54-65
doi	https://doi.org/10.52842/conf.acadia.1999.054
summary	This research explores the feasibility of Web technology as a means for delivering building information to better support facility operations. Our research proposes just-in-time (JIT) facility documentation as a pragmatic solution to the limitations of current as-built documents, allowing more effective reuse of building information. Our investigation addresses four issues: 1) what building information is needed for facility operations; 2) how the design and construction team can improve the format for delivering the building information to facility operators; 3) how current Web technology can store and deliver facility information in support of operations; 4) what is the mechanism of documenting building information using the Web technology. // We surveyed literature, interviewed members of design and operations teams and reviewed current initiatives of industry and software vendors to identify problems with current practices. We also surveyed promising Web technologies and conducted experiments to determine how these technologies could help to solve the problems. We constructed a conceptual framework of JIT facility documentation as a solution to current information fragmentation problems. We developed a prototype of the JIT document system to demonstrate a “proof of concept” by using current Web technologies such as Autodesk’s DWF, Microsoft’s Active Server Pages, VB and Java script, and Access database to develop the prototype system. By dynamically composing HTML pages in response to task-specific requests, our prototype enables easy access and integration of a variety of building information to support facility operations.

title	Product modeling standards for the building and construction industry: past, present and future
source	Automation in Construction 8 (3) (1999) pp. 227-235
summary	For the past ten years most sectors of industry have been developing standards for the electronic sharing and exchange of product model data. While several related industries, such as automotive and shipbuilding manufacturing have been relatively successful in integrating electronic product models into their operations, the building and construction industry, continues to lag behind in this development. In order for the building and construction industry to meet the challenges of the future, the development of a product modeling standard that enables sharing, storing and exchanging project information electronically is essential. The paper discusses the rationale behind this assertion and includes a discussion of the industry requirements for the development of a product modeling standard. The paper elaborates on the results of the standardization efforts of the past and present, followed by an analysis of the current development situation. Finally, personal views are expressed regarding future development in the area of information exchange.

doi	https://doi.org/10.52842/conf.ecaade.1999.169
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 virtual design studio (VDS) points to a new way of practicing and teaching architectural design. As a new phenomenon, little research has been done to evaluate design collaboration and multimedia usage in a distributed workplace like the virtual design studio. Our research provides empirical data on how students actually use multiple media during architectural collaborative design.
