summary The sketch is the embodiment of the architectural discussion. It incorporates rapidness and fuzziness and as this it is an object of interpretation. The interesting thing there is the question, if the usage of VR/AR already in the early phases of a design can have an impact for the quality of a design-process. Examples like VRAM (Regenbrecht et al., 2000) or TAP (Seichter et al., 2000) showed that there is a huge potential for research. The sketch as one of the parts of an early design is tightly coupled with cognitive aspects and communication. Pictured by a sketch is just a snapshot of what have to be discussed in the ensuing design procedure. The intention behind this work is an exploration about a medium which is not yet adapted to the digital world (Myers et al., 2000) and it can be easily be described with the words of Harald Innis: Mankind constantly being caught in his own traps: language and systems, developed and most difficult to break down.

title The Geographical Alpine Information System “Galpis” in the Raumalp Project. Outlay and Output
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary RAUMALP, an interdisciplinary research project of the Austrian Academy of Sciences, shall examine problem areas of spatial development on community level in the Austrian alpine region. The aim is the investigation of scientific basics for political decision finding, especially for the regional-specific realisation of the Alpine Convention. All ascertained information shall be included in “GALPIS”, a comprehensive Alpine Space Information System. GALPIS based on ESRI ArcGIS and MS Access software works with data from different sources, like ISIS, the electronic data base of Statistic Austria, and original data and maps gathered and elaborated by the working groups of RAUMALP. This also includes ecological raster data. Dealing with administrative units, „real“ space and raster space, RAUMALP will integrate the different space levels mostly to administrative spatial units representing the existing 1145 communities of the RAUMALP study area. This will be realised by overlay of grids, types of land use and communitypolygons. Major task of GALPIS is a conversion of former communal data (p. e. 1451 communities in 1951) that should represent the recent administrative boundaries. By this way it is possible to make thematic and time-integrative analyses of community data. GIS modelling of the six case studies is more complex. The conceptual model has to integrate several vector and raster layers such as land plots (“Digitale Katastralmappe”), types of land use (“Land Use and Land Cover Austria” by M. Seger) and biodiversity. P. e., the working group settlement is using a logical data model based on the entity “building” with the attributes “construction”,“function”, etc.

summary This article refl ects on the digital reconstruction of the Vinohrady Synagogue in Prague, which was demolished in 1951. Based on an international collaboration through the Erasmus program, expertise derived from other Viennese synagogue reconstructions at TU Vienna was combined with a resource organization methodology developed at KU Leuven. The reconstruction process is carried out using BIM software, which poses some particular attention on the software methodology and model structure, but at the same time illustrates the added value of a BIM approach, when comparing with more traditional CAD modelling systematics. Of particular interest is the approach for modelling complex geometry, integrating with more traditional 2D documents and for visualizing reconstruction assumptions within the 3D model representation.

title Creativity in Invention and Design
source Cambridge University Press
summary In this book, creativity in technology is discussed using a computational approach. Examining an important historical episode in computer technology as a case study, namely, the invention of microprogramming by Maurice Wilkes in 1951, the author presents a plausible explanation of the process by which Wilkes may have arrived at his invention. Based on this case study, the author has also proposed some very general hypotheses concerning creativity that appear to corroborate the findings of some psychologists and historians and then suggests that creative thinking is not significantly different in nature from everyday thinking and reasoning.

title LOS "SPIROSPACES"
source Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 179-187.
summary This paper deals with “Spirospaces”. These are a conversion to the third dimension of the two dimensional geometric entities called “Spirolaterals”.

Abelson, Harold, diSessa and Andera (1968) gave the first rules concerning Spirolaterals. To obtain a Spirolateral from a set of straight lines, the first of them must be one unit long and the following must be incremented one unit at each step, at the same time that they turn in a constant direction. Odds (1973) establish the variation of the rotation direction, either to the left or the right. However, he did not give a mathematical relation able to calculate open Spirolaterals. Krawczyk (2001) developed a computer program that generates Spirolaterals following the method suggested by Abelson. These are Spirolaterals obtained by enumeration without a predictive mathematical formula. Krawczyc went farther proposing Spirolaterals based in curved lines. He pointed out that there are a variety of spirolateral forms that have architectural potentiality. Following this, the architectural potentiality of Spirolaterals is the basis of this paper.

To take advantage of that potentiality a computer program was implemented to generate spatial configurations based in Spirolaterals. When a third dimension is given to the Spirolaterals they become Spirospaces. These new entities need spatial and design parameters to be useful for architectural purposes. Barrionuevo and Borsetti (2001) gave results about that work establishing the concept of Spirospaces.

The aim of this paper is to describe a work directed to improve rules and procedures concerning Spirospaces. It is expected that these procedures governed by the proposed rules can be employed as tools during the early steps in the architectural design process.

In this work some aspects concerning Spirospaces are considered. First, Spirolaterals are presented as the predecessors of Spirospaces. Second, Spirospaces are defined, together with their structural parameters. Architectural modeling is studied at the light of two special elements of the Spirospaces: Interstitial spaces and Object spaces. Next, a computer program is presented as the appropriate tool to model configurations having architectural potentiality. Finally, the results obtained running the computer program are analyzed to determine their possible use as architectural forms. Several graphic illustrations are presented showing steps going from the exploration of spatial alternatives to the selection of a specific configuration to be developed.

It is expected that the described computer program could be employed as a design aid tool. As the operation of the program generates a variety of spaces able to dwell architectural objects, it eases the search of configurations suitable to specific functions. The results obtained have the possibility of being exported to computer graphic applications able to add materials, lights and cameras.

title The Development of Three-Dimensional Spatial Modeling Techniques for the Construction of Nuclear Power Plants
source SIGGRAPH-ACM Quarterly Report. August, 1978. pp. 26-30 : ill. includes bibliography
summary This paper presents the results of the first phase of a research project on the application of spatial modeling techniques to the process of planning and executing the construction of a nuclear power plant. A computer modeling technique, based on sets of polyhedra and spatial set operations, was developed and applied to modeling the components of a nuclear power plant. The objectives of the modeling are: To store and retrieve information about the various systems in the facility; to produce drawings of those systems from any angle in differing amounts of detail; to aid in the search for interference among the parts of the plant by identifying those elements that occupy the same space or are too close to each other; to calculate information such as surface area, length, and volume of selected elements of the plant; and to aid in finding the optimum construction sequence by simulating the construction of selected areas of the plant. Computer techniques are described for inputing information by digitizing directly from engineering drawings, for editing the spatial model, for management of the spatial and non-spatial data, and for graphic output from the model. The software is implemented on the University central time- sharing computer system and on a mini-computer system in the Architectural Research Laboratory

The two buildings share similar educational responsibilities for the public, offering a variety of programs and facilities. In addition, they also assume a related physical presence on their respective sites, due to a similarity in the size of the building programs.

title A Data Flow Approach to Procedural Modeling
source IEEE Computer Graphics and Applications January, 1984. vol. 4: pp. 16-26 : ill. (some col.). includes bibliography.
summary Computer graphics tasks generally involve either modeling or viewing. Modeling combines primitive building blocks (polygons, patches, etc.) into data structures that represent entire objects and scenes. To visualize a modeled object, its data structure is input to appropriate viewing routines. While a great deal has been done on modeling and viewing with geometric primitives, little has been published on the use of procedural primitives. A procedural model is a step-by-step guide for constructing a representation of an object or process, i.e., a program. It is also a function, a 'black box' with a set of inputs and outputs. Two questions are especially pertinent to the work presented in this article
keywords First, what are the advantages of both data flow methods and procedural modeling? Second, how can such models be used in composition? computer graphics, modeling, information, management

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 How I Drew One of My Pictures: * or, The Authorship of Generative Art
source International Conference on Generative Art
summary The concept of value is traditionally bestowed on a work of art when it is seen to be unique and irreproducible, thereby granting it authenticity. Think of a famous painting: only the original canvas commands genuinely high prices. Digital artwork is not valued in the same way. It can be copied infinitely and there is therefore a corresponding crisis of value. It has been argued that under these conditions of the dematerialised artwork, it is process that becomes valued. In this way, the process of creation and creativity is valued in place of authenticity, undermining conventional notions of authorship. It is possible to correlate many of these creative processes into instructions. However, to give precise instructions on the construction of a creative work is a complex, authentic and intricate process equivalent to conventional creative work (and is therefore not simply a question of 'the death of the author'). This paper argues that to create ‘generative’ systems is a rigorous and intricate procedure. Moreover, the output from generative systems should not be valued simply as an endless, infinite series of resources but as a system. To have a machine write poetry for ten years would not generate creative music, but the process of getting the machine to do so would certainly register an advanced form of creativity. When a programmer develops a generative system, they are engaged in a creative act. Programming is no less an artform than painting is a technical process. By analogy, the mathematical value pi can be approximated as 3.14159265, but a more thorough and accurate version can be stored as the formula used to calculate it. In the same way, it is more complete to express creativity formulated as code, which can then be executed to produce the results we desire. Rather like using Leibnitz's set of symbols to represent a mathematical formula, artists can now choose to represent creativity as computer programs (Harold Cohen’s Aaron, a computer program that creates drawings is a case in point). By programming computers to undertake creative instructions, this paper will argue that more accurate and expansive traces of creativity are being developed that suitably merge artistic subjectivity with technical form. It is no longer necessary or even desirable to be able to render art as a final tangible medium, but instead it is more important to program computers to be creative by proxy.

summary Singapore is possibly the first country in Asia to implement a nation-wide electronic system for the evaluation and approval of building plans called ELECTRONIC BUILDABILITY DESIGN APPRAISAL SCORE (eBDAS). The system is a systematic and comprehensive method of computing a building design’s buildability efficiency through a scoring methodology. Using this methodology, the building authorities make the decision as to whether a building is approved for construction. Poh and Chen (1996) have found that a design with a higher buildable score results in more efficient labour usage in construction and therefore higher site labour productivity. However, the relationship between construction costs and buildable score was found less distinct. This paper discusses the existing implications of eBDAS on the architectural profession and potential implications on educational institutes.

title Matchmaker: An Instrument for Matching Demand for and Supply of Buildings and Revealing Specific Discrepancies
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary To match supply and demand of buildings, various approaches are possible. While artificial intelligenceis favoured by some, we think that a less 'heavy' approach can be more cost and time efficient. The casewe have chosen to exemplify our approach concerns architectural heritage. To match supply and demandwhile at the same time respecting the constraints imposed by cultural heritage, it is necessary to bringthem together and to effectuate feasibility studies in the shortest possible time. The feasibility study shouldbe served by tools allowing the various partners to communicate on the level of the match between them, translated in terms of spatial organisation and building constraints. In the past years, our designmorphology group has developed and tested a graphic-based reordering tool which has been applied to large governmental buildings, both existing and new. The same tool can be used for weighted objectives ranking and evaluation, to have a synthetic view of the combined basic preferences and differences of the involved parties as for example in a jury wise evaluation and ranking of alternative proposals. The proposed tool is the electronic and graphic version of the data and association matrices, which have been for a long time recommended for use in the preliminary phases of design. But as long as these instruments could only be drawn and redrawn on paper they were much too ineffectual and found little real application. The developed tool is connected by sub-routines to a computer aided design package, within which the spatial patterns are translated into plans and attached data bases. The matching takes place in a number of steps. The first is to describe the organisation (the demanding party) as functional units which can be made corresponding with spatial units. The prescription of spatial needs can take place in both quantitative and qualitative manners. The Matchmaker tools offer the possibility of interactive clustering of spatial needs. Another step, which can be taken concurrently, is to describe the monument in spatial units and distance relationships. The input can be generated directly within the matrix, but it is much easier, more self evident and realistic to generate this automatically from the draughted plan. The following step is the input of constraints originating from heritage preservation objectives, expressed in levels of authorised intervention. Again, the Matchmaker tools offer here the possibility of visual clustering of spatial units, their relationships and associated properties. In the next step, the matching takes place. In this step the actual positions, properties and constraints of existing spaces in the monument are compared (and visualised by discrepancies views) to the optimised and clustered spatial needs of the end user. In the following phase, the feasibility in terms of space, building fabric and costs can be appraised. Once a compromise has been attained, preliminary proposals can be designed and laid down in terms of drawings. The spatialdesigns can then again be translated into matrix views and evaluated.

summary The increasing trend in architecture to create unconventional forms opened up a new area of investigations in the employment of computational methods in design and construction. Our investigation is undertaken within a structural engineering firm, Adams Kara Taylor and focuses on finding ways to design structural solutions that respect criteria of efficiency, architectural intentions as well as intrinsic properties of the geometry. In this paper, we present various approaches on discretization where a project is presented as a continuous form, envelope or skin that must be subsequently subdivided in order to yield a framing or cladding solution compatible with different manufacturing, design and engineering considerations. The first part of this paper illustrates such a project where we applied and developed one of our discretization approaches. The second part of the paper focuses on generalization where we present a series of methodologies and corresponding software tools developed for the purpose.

title A fuzzy navigation system for mobile construction robots
source Automation in Construction 6 (2) (1997) pp. 97-107
summary Fuzzy navigation systems control a robot by implementing a fuzzy logic controller (FLC). Fuzzy navigation systems are simpler to implement than other navigation systems because they can handle infinite navigation situations with a finite set of rules. Existing fuzzy navigation systems for path finding in an unknown environment tend to find the shortest path in convex obstacle fields, but fail when obstacles are concave or placed continuously in certain configurations. This paper presents a fuzzy navigation system that can escape from concave and maze-like obstacle fields in an unknown environment. The system combines a tangent algorithm for path planning with sets of linguistic fuzzy control rules. In particular, we introduce the control rules for a Tracking mode of the FLC and improvements to the commonly used, intuitively reasonable tangent algorithm.
