title	KOALA - Developing a generative house design system with agent-based modelling of social spatial processes
doi	https://doi.org/10.52842/conf.caadria.2019.1.235
source	M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 1, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 235-244
summary	The paper presents the development of an agent-based approach to modelling the interaction of human emotion and behaviour with built spaces. The study addresses how human behaviour and social relation can be represented and modelled to interact with a virtual built environment composed in parametric architectural geometry. KOALA, a prototype of agent-based modelling of social spatial dynamics at the core of a parametric architectural design environment is proposed. In building KOALA's system architecture, we adapted the PECS (Physical, Emotional, Cognitive, Social) reference model of human behaviour (Schmidt 2002) and introduced the concept of Social Spatial Comfort as a measurement of three key factors influencing human spatial experiences. KOALA was evaluated by a comparative modelling of two contrasting Vietnamese dwellings known to us. As expected, KOALA returns very different temporal characteristics of spatial modifications of the two dwellings over a simulated timeframe of one year. We discuss the lessons learned and further research required.

title	Conformance Checking by Capturing and Simulating Human Behaviour in the Built Environment
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	In order to model natural human behaviour, it is necessary to capture this behaviour. First, we will start out by modelling behaviour for specific situations, such as taking a seat in a theatre. To capture humanbehaviour, the following experiment is performed: Given a virtual environment, a sufficient number of subjects (real humans) are asked to execute a human task in this virtual environment (e.g. take a seat inthe theatre). Whenever the subject deviates from the shortest path, the system will ask for a clue why this is done. The hypothesis is that the combination of the motion paths and the clues for making/changing decisions will provide decision rules to make reliable predictions about human behaviour under the same conditions when using virtual persons. To test the hypothesis, we propose to use the university’s main conference and presentation hall as a test case. A 3D model and a motion pathgraph are constructed that enables a virtual person to find its way to a selected chair. The clues from the experiment are implemented as decision rules that determine a virtual person’s behaviour. Running thesimulation will result in the following data: Time per person to find a chair, Deviation from the shortest path, Distance covered per person to find a chair, Distribution of seated persons over time and Relocation of persons. To validate the test case, the process of people entering the hall and finding a chair is recorded on videotape. The walking behaviour of the people observed on the video is analysed and compared with the data from the simulation.

title	GIS Tools for Landscape Impact Assessment
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary	This paper present the main results obtained by the development of the Artemis Project ”Design and Evaluation of Residential Patterns in the Mediterranan Region appropiate to sustainable development of environmentally deteriorated rural areas” 4th European Framework Program. Call ENVIRONMENT AND CLIMATE . ENV4-CT97-0656.) As results of the project an Integrated Landscape Assessment Model (AIAM) was created. AIAM is a resource modelling system focusing on the generation of a decision support system application oriented to provide criteria in order to evaluate effects and to optimise location of low density residential settlements. The Model includes a Landscape multicriteria analysis merged with spatial analysis tools set in a GIS Environment. The A.I.A.M. provides data structures, user interface components, and output mechanism witch allows the user to apply the knowledge acquired for Artemis Project. One of the main goals of the A.I.A.M is to give a landscape view of the territory including variables that are usually not considered in planning and environmental impact assessment processes. Also the models gives a sustainable support both to planner and designers projects. A.I.A.M. gives the data structure to define a residential patterns, the parameters through which a pattern is adequately described. This pattern definition allows comparison between the one’s of the reference area and so, extract conclusions about divergence between them.

title	Computer-generated physical modelling in the early stages of the design process
source	Automation in Construction 11 (3) (2002) pp. 303-311
summary	This paper illustrates some of the opportunities arising from the introduction of computer-generated physical modelling1 in the early stages of the architectural design process. The use of this technology in the design process differs from previous research and practise in that it looks at the use of computer-generated physical modelling recursively in design process rather than as a means to create a final presentation model [W.J. Mitchell, M. McCullough, Digital Design Media, Van Nostrand Reihnold, New York, 1994]. Previous research in the field by the author identified recursive strategy in the design process as the area in which computer-generated physical modelling offers unique opportunities to the designer. Three unique advantages in the use of computer-generated physical modelling technology are illustrated by three case studies. These advantages are: (1) understanding kinetic design, (2) understanding design involving complex geometry and (3) understanding design at the interface with the human body.

title	Urban Sprawl Modelling: Combining Models to Make Decision
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary	Urban sprawl is frequently associated with the idea of an unsuitable development, leading to increasing economic, social and environmental problems. Moreover, its control is difficult because multiple patterns (concerning numerous traditional urban planning fields) overlap. In order to understand the sprawl process and to manage its consequences, it must be simplified. The construction of a decision making tool appears then interesting. The GIS-based tool presented here is being developed incollaboration between the urban planning agency of Belfort and the laboratory of geography of Strasbourg. It requires three steps: 1. quantification of the sprawl (how much areas are involved in theurban sprawl process?); 2. location of the sprawl (where are the areas defined in the first step?); 3. differentiation of the sprawl (what are the areas located in the second step?). Of course, the successionof the three stages makes the use of the complete model more complex. So, a global ergonomic user interface is being developed within the GIS, allowing to modify each parameter and to play easily numerous simulations.

title	From 2D Base Map To 3D City Model
source	UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, I.17-I.28
summary	Since 1997 Helsinki City Survey Division has proceeded in experimenting and in developing the methods for converting and supplementing current digital 2D base maps in the scale 1:500 to a 3D city model. Actually since 1986 project areas have been produced in 3D for city planning and construction projects, but working with the whole map database started in 1997 because of customer demands and competitive 3D projects. 3D map database needs new data modelling and structures, map update processes need new working orders and the draftsmen need to learn a new profession; the 3D modeller. Laser-scanning and digital photogrammetry have been used in collecting 3D information on the map objects. During the years 1999-2000 laser-scanning experiments covering 45 km2 have been carried out utilizing the Swedish TopEye system. Simultaneous digital photography produces material for orto photo mosaics. These have been applied in mapping out dated map features and in vectorizing 3D buildings manually, semi automatically and automatically. In modelling we use TerraScan, TerraPhoto and TerraModeler sw, which are developed in Finland. The 3D city model project is at the same time partially a software development project. An accuracy and feasibility study was also completed and will be shortly presented. The three scales of 3D models are also presented in this paper. Some new 3D products and some usage of 3D city models in practice will be demonstrated in the actual presentation.

title	Quantitatively Analysing Parametric Models
source	International Journal of Architectural Computing vol. 12 - no. 3, 307-320
summary	Architectural practices regularly work with parametric models, yet almost nothing is known about the general properties of these models. We do not know how large a typical model is, or how complicated, or even what the typical parametric model does. These knowledge gaps are the focus of this article, which documents the first large-scale quantitative parametric model survey. In this paper three key quantitative metrics - dimensionality, size, and cyclomatic complexity - are applied to a collection of 2002 parametric models created by 575 designers. The results show that parametric models generally exhibit a number of strong correlations, which reveal a practice of parametric modelling that has as much to do with the management of data as it does with the modelling of geometry. These findings demonstrate the utility of software engineering metrics in the description and analysis of parametric models.

title	Free-form design using axial curve-pairs
source	Computer-Aided Design, Vol. 34 (8) (2002) pp. 583-595
summary	Deformation of 3D shapes usually requires the use of a deformation tool. The freeform deformation technique requires the use of a lattice of control point for deforming anobject. This may require a synchronized movement of the lattice control points in order to obtain the desired effects. The axial deformation technique allows an object to bedeformed by manipulating an axial curve. However, unexpected twist of the object may be obtained. This is a result of the lack of control on the local coordinate frame of thecurve. This paper presents a technique for deforming objects with a set of axial curve-pairs. The use of a curve-pair allows the local coordinate frame to be controlledintuitively. A curve-pair is composed of a primary and an orientation curve. The orientation curve is an approximate offset of the primary curve. A technique is proposed formaintaining the relation between the primary and the orientation curve when the curve-pair is adjusted. By associating a complex 3D object to a curve-pair, the object can bestretched, bended, and twisted intuitively through manipulating the curve-pair. This deformation technique is particularly suitable for manipulating complex shapes (e.g.decorative components) in industrial and aesthetic design, and is also suitable for modelling characters and animals with flexible bodies. Adjusting the curve-pair according tosome motion constraints produces different postures of a character or animal model. This in turn can be used as decorative components for aesthetic design.

title	DEFINITION OF A METHOD OF LIMITS OF THE SIMPLIFICATION OF A HALL MODEL IN A CAD SYSTEM TO DIMINISH FALSIFICATION OF ACOUSTIC SIMULATION RESULTS
source	International Congress eCAADe 2005 (Education and research in Computer Aided Architectural Design in Europe), subject : “Digital Desing : the quest for new paradigms”, ISBN 0-9541183-2-4, pp. 695-704, Technical University of Lisbon, Portugal, 21-24 September 2005
summary	During the modelling, because of the sometimes complex architectural shape of halls, we were forced to introduce simplifications in order to carry out calculations and simulation operations on these halls, as the calculation software requires plane surfaces. This paper presents a developed tool adapted on a CAD modelling system (AutoCAD), which defines an “average limits” of the model simplification operation in order to control and diminish the falsification of calculation and simulation results on this model, such as the architectural acoustic simulation. The process of the elaboration and the adjustment of the simplified models of the Grand Theatre of Bordeaux (GTB) based on acoustical measurements and their calculation results are described in detail in a previous article (Kouzeleas and Semidor, 2001). The analysis process of the consequences of the hall model simplification on the acoustical simulation results and the applied simplification methods are described in a PhD thesis (Kouzeleas, 2002). This article is based on this analysis process in order to apply it on several simplified models of the Amphitheatre of the Architecture School of Bordeaux (Amphi-EAPB). The comparison in a CAD system (AutoCAD) of the acoustical calculation results and the areas after simplification of the simplified models of these two halls made with AutoCAD, via the developed tool adapted on the AutoCAD, permit to define a “limits average of a hall model simplification” before the falsification of these calculation results.

source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 299-300
summary	This paper shows the results of 3-D modelling carried out on works of great architectural value. This case corresponds to the building system of Villa Victoria Cultural Center, Mar del Plata, Argentina. The building of a 3-D Digital Model implies the operations of geometric modelling by using Parametric CAD systems in this case, and to the operations of visual modelling in all respects. The analysis focused on three aspects: the morphological aspect, which comprises the visualization and the analysis of the model shapes; the constructional aspect, which deals with the component elements of the model ; and the realistic aspect, where shapes are complemented with appearence by incorporating materialization features which relate to the perception of the finished model.

title	Urbamedia Desarrollo de una base de datos de fragmentos urbanos de ciudades argentinas y latinoamericanas utilizando tecnología digital “VRML” (Virtual Reality Modelling Language) [“Urbamedia” Database Development of urban fragments of Argentinean and Latin cities utilizing the digital technology of VRML (Virtual Reality Modeling Language)]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 112-115
summary	The proposal of “Urbamedia” is to undertake the development of a 3D virtual and interactive model of an historical area of the city of Buenos Aires. The selected zone is the “Mayo Avenue” including the “Mayo Square”; this project is financed by the National Agency of Scientific and Technological Development of Argentina and the University of Buenos Aires.We are presenting and experimental model of the “Mayo Square” that has been developed at ABACUS, Department of Architecture & Building Aids Computer Unit, University of Strathclyde UK. We are also looking to include histórical areas of three cities (Mar del Plata, Rosario and Santa Fe) and eventually other cities from Latin América. Due that ABACUS has a strong experience in city modelling plus the powerful software and hardware used there, we must develop a VRML customized menu to be adapted to our low cost PC equipment. The 3D model will be used mainly in urban design simulation procedures and the idea is to extend to other type of simulationsof the environmental parameters.

title	Rapid design and manufacture tools in architecture
source	Automation in Construction 11 (3) (2002) pp. 279-290
summary	The continuing development of Rapid Prototyping technologies and the introduction of Concept Modelling technologies means that their use is expanding into a greater range of applications. The primary aim of this paper is to give the reader an overview of the current state of the art in Layered Manufacturing (LM) technology and its applicability in the field of architecture. The paper reports on the findings of a benchmarking study, conducted by the Rapid Design and Manufacturing (RDM) Group in Glasgow [G.J. Ryder, A. McGown, W. Ion, G. Green, D. Harrison, B. Wood, Rapid Prototyping Feasibility Report, Rapid Prototyping Group, Glasgow School of Art, 1998.], which identified that the applicability of LM technologies in any application can be governed by a series of critical process and application specific issues. A further survey carried out by the RDM group investigated current model making practice, current 3D CAD use and current use of LM technologies within the field of architecture. The findings are then compared with the capabilities of LM technologies. Future research needs in this area are identified and briefly outlined.

source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 31-34
summary	Computers can be used as a key research tool because they allow us to do things that have been difficult or unfeasible in the past. This potential could facilitate discussion of ideas in new ways. This paper presents preliminary findings of a computational model that may contribute to extend our –presently limited – understanding of creative phenomena in design. As part of an extensive modelling effort, it offers initial insights that may shift the current focus in individual creativity to a more extensive view where the situations within which designers operate play a key role in the occurrence and definition of creativity.

title	Ecomorphic Dialogues
source	International Conference on Generative Art
summary	The biological concept of ecomorphology examines the morphology of the organism in relation to the environment it inhabits. However, the organism itself is an active agent that shapes the environment that in turn shapes it. The two are linked through what autopoietic theory calls structural coupling, and thus the environment itself evolves as an ecomorphic entity. This short paper discusses modelling the process of ecomorphic evolution of an art gallery, which is built around the natural interaction, or hermeneutic dialogue, between people and artworks within it. The natural interactions from the point of view of the person are those based on active perception of the environment, that is, based solely on possiblities that the environment affords to the person. In the model presented here, the possibilities of the gallery are to view the artwork on display, and agents with vision act out the part of the people. However, the artwork itself is engaged in a game in which it tries to place itself in popular rooms within the gallery, moving from location to location to achieve this. Around this visually coupled interaction between viewer and artwork, the walls of the gallery are formed and reformed according to the location of the players, in order to create a constantly evolving space in which the game is played: the ecomorphic dialogue of artwork and art viewer.

title	Computer Aided Dimensional Control in Building Construction
source	Eindhoven University of Technology
summary	Dimensional control in the building industry can be defined as the operational techniques and activities that are necessary, during the construction process of a building, for the assurance of the defined dimension quality of a building (Hoof, 1986). Efficient and precise dimensional control of buildings under construction is becoming ever more important because of changes in the construction industry. More prefabricated components are used; more regulations appear; newly designed buildings have more complex shapes, and building construction is speeding up. To ensure the predefined dimensional quality, a plan of dimensional control must be designed, on the basis of building drawings and specifications delivered by architects, before the building is constructed. The dimensional control plan must provide site personnel with adequate information on, among others, setting out and assembling building components, which can often be done by means of Total Stations. The essence of designing a dimensional control plan is to find out which points should be used as positioning points, which points should be set out in advance or controlled afterwards, and not to forget why. In an effort to contribute to the improvement of the dimensional control of on-site construction projects, this research tries to capture the knowledge required to design an adequate dimensional control plan and make that knowledge more generally available, and build a digital connection between CAD systems and Total Stations, focusing on prefabricated concrete building structural elements. The instrument developed in this research for capturing of essential dimensional control information and knowledge makes use of Product Data Technology (PDT) and Knowledge Technology (KT). The chosen solution supports the stochastic analysis of optimal positioning points taking account of various sorts of deviations and their mutual relationships. The resulting information model has been written in a standardized information modelling language called UML (Unified Modelling Language). The model has been implemented in a Dimensional Control System (DCS) and applied in the “La Tour” construction project in Apeldoorn, the Netherlands. The DCS provides a digital way to bridge the floor plan design with dimensional control, predict dimensional deviation limits and output the data needed for a Total Station. The case study of “La Tour” tests the UML model and prototype of the DCS. The results prove that direct positioning of objects (by putting reflectors on the objects and using a Total Station and by inputting coordinates extracted and calculated from the AutoCAD drawings) provides higher speed, accuracy and reliability. It also shows a way to (pre)position free form objects in 3D where traditional methods cannot. In conclusion: (1) it seems to be justified to expect that the application of the DCS will contribute to increased confidence in dimensional control and the reduction of costs of failure, which potentially could support the increased use of cheaper construction methods, and will also contribute to the improvement of building design and construction process. (2) the scientific contribution of this research is a first step towards providing dimensional quality in a construction process covered by stochastic dimensional uncertainty, even for positioning of free form objects.

title	Artificial Design and Planning Support: Interactive Plan Generation andCoordination in Distributed Decision-Making
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary	In this paper we discuss some basic issues pertaining to artificial plan design as a paradigm for architectural design and urban planning support. We present a model for artificial design generation based on learning control methodologies. Plan design is seen as a search for "coordinated" solutions (changes) that satisfy distributed domain requirements and views expressed by human or artificial agents. Learning control is used as a method to search for solutions that direct partial descriptionsproduced by agents, to follow their dynamically defined targets -despite conflicting requirements. The model is simulated for land use and layout plan design, involving decisions for the location and physical configuration of a hypothetical housing and retail development.

title	Design space navigation in generative design systems
source	Automation in Construction 11 (1) (2002) pp. 1-22
summary	Generative design systems make it easier for designers to generate and explore design alternatives, but the amount of information generated during a design session can become very large. Intelligent navigation aids are needed if designers wish to access the information they generate with ease. We present a comprehensive approach to support information navigation in requirement-driven generative design systems, which gain their power form explicit representations of design requirements, which in turn add to the information generated by the system. Our approach takes into account studies dealing with human spatial cognition, wayfinding in physical environments, and information navigation in electronic media. We structure the information to be accessed in terms of a five-dimensional design space model that applies across generative design systems of the type considered here. The model structure supports basic generic navigation operations along its five dimensions. We validated the model in the context of the SEED-Layout system and used it to extend the built-in navigation tools of the system through novel ones, which we subjected to a limited usability study. The study suggests that these tools have promise and warrant further investigation.

title	New Expectations: City Modeling in the Internet Age
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 97-100
summary	The first part of this paper tries to give an overview over the different aspects of city modeling. After a short history on city models the paper starts with a categorization of the different “types” of city models. We try to explain the various aspects involved in the creation of a city model and the problem of maintaining a city model. Then the paper shows the example of two computer models of parts of the same European city which have been created in two different ways. The first version of this computer model tries to use as many automatic or semi automatic procedures as possible to create the model. In the paper examples of these differentprocedures are given - from the automatic creation of the buildings itself, its roofs, and the surrounding terrain to the automatic cleaning of texture photos of the façade. The second version shows a model, which has been done with just a few automatic procedures and a lot of human effort (mainly students). The paper describes the limitation of both techniques and tries to give an outlook towards the combination of these methods. We will also show the importance of internet techniques in the use and presentation of computer city models.
