summary The paper introduces a Multi Agent Systems (MAS) approach to crowd modelling and simulation, based on the Situated Cellular Agents (SCA) model. This is a special class of Multilayered Multi Agent Situated System (MMASS), exploiting basic elements of Cellular Automata. In particular SCA model provides an explicit spatial representation and the definition of adjacency geometries, but also a concept of autonomous agent, provided with an internal architecture, an individual state and behaviour. The latter provides different means of space-mediated interaction among agents: synchronous, between adjacent agents, and asynchronous among at-a-distance entities. Heterogeneous entities may be modelled through the specification of different agent types, defining different behaviours and perceptive capabilities. After a brief description of the model, its application to simple crowd behaviours will be given, and an application providing the integration of a bidimensional simulator based on this model and a 3D modelling application (3D Studio) will also be described. The adoption of this kind of system allows the specification and simulation of an architectural design with reference to the behaviour of entities that will act in it. The system is also able to easily produce a realistic visualization of the simulation, in order to facilitate the evaluation of the design and the communication with involved decision-makers. In fact, while experts often require only abstract and analytical results deriving from a quantitative analysis of simulation results, other people involved in the decision-making process related to the design may be helped by qualitative aspects better represented by other forms of graphical visualization.

title Location Modeling for Ubiquitous Computing Based on a Spatial Information Management Technology
doi https://doi.org/10.52842/conf.caadria.2004.787

summary Location modeling, which generally has influence on location-aware applications, is a critical and interesting aspect. In the ubiquitous computing, location modeling has been discussed as one of fundamental research subject, because a location is a very essential element of contexts and useful information for other applications related with ubiquitous computing. Especially, location modeling in architectural space should be defined through the comprehension of the physical environment, because the users' (or objects) location does not only mean numerical coordinates, but also refers to the situation related to users' (or objects) physical contexts. In other hands, location model for architectural space should be based on the simplification of complicated physical environment, the consideration of corresponding various changes, and also the definition for the relationship of spatial information. Traditionally, those issues have been actively studied in the fields of CAAD (Computer Aided Architectural Design) research and could used effectively for ubiquitous computing system. This paper proposes the location model and its utilization method which can be applied on making the ubiquitous computing system in the architectural space based on CAAD theories. At the end of the paper, we present a CAAD system, called “Vitruius”, in order to define architectural spaces appropriately and manage them easily for the ubiquitous computing environment.

title A survey of computer software for the urban designprocess

summary Urban design is concerned with the shape, the surface and the physical arrangement of all kinds of urban elements, the basic components that make up the built environment, at the level of buildings, spaces and human activities. It is also concerned with the non-visual aspects of the environment, such as noise, wind and temperature and humidity. The city square is a particular urban element which can take many forms and its geometrical relationships such as maximum dimensions, ratio of width to length and building height to length have been analysed for centuries (Alberti 1475), (Vitruvius 1550), (Sitte 1889), (Corbett 2004). Within the current urban design process there are increasing examples of three dimensional computer representations which allow the user to experience a visual sense of the geometry of city squares in an urban landscape. Computer-aided design and Virtual Reality technologies have recently contributed to this visual assessment, but there have been limited attempts at 3D computer representations which allow the user to experience a greater sense of the urban space. This paper will describe a survey of computer tools which could support a more holistic approach to urban design and which could be used to simulate a number of urban texture and urban quality aspects. It will provide a systematic overview of currently available software that could support the simulation of building density, height, colour and style as well as conditions relating to noise, shading, heat, natural and artificial light. It will describe a methodology for the selection and filtering of appropriate computer applications and offer an initial evaluation of these tools for the analysis and representation of the three-dimensional geometry, urban texture and urban quality of city centre spaces. The paper is structured to include an introduction to the design criteria relating to city centre spaces which underpins this research. Next the systematic review of computer software will be described, and selected tools will undergo initial evaluation. Finally conclusions will be drawn and areas for future research identified.

title HCIS: the Housing Context Inference System Model for Smart Space
doi https://doi.org/10.52842/conf.caadria.2004.759
source CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 759-776
summary This research is about the basic methods in making computers understand human behavior in an architectural space in regards to reaction to interaction between the machine and human. Its ultimate objective is to analyze the related technology making this series of works possible synthetically on the basis of information system within architectural territoriality. In the end it is expected to offer a theoretical basis to embody smart space, up-to-date and intelligent architectural space. There are two issues that motivate this research: what are the Housing Context and its Inference System, and how smart space can infer the Housing Context and react with proper response. The Husing Context consists of 1) state of user, 2) state of physical environment, 3) state of computational environment, 4) history of user-environment interaction and 5) architectural territoriality. Especially, spatial information of architectural territoriality is a significant key of HCIS. Spatial divisions and boundaries made of architectural elements or facilities determinate their own micro-territorialities. Ontologies are used to describe the Housing Context predicate. In this paper, we can say that the Housing Context and the Housing Log(history of user-environment interaction, a set of the Housing Context) written by ontologies can be a beneficial model of HCIS. Furthermore, we can develop the Housing Log Databases and its variable applications that have enabled to make simulating and analyzing tool of design, the Augmented Web Presence and the other helpful applications.

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 About Virtual Spatial Modeling in Architectural Education

summary The professional perception of the architectural space characterizes the most advanced level of the architect’s mastership. In the article the virtual modeling is regarded as an effective way of forming the professional perception of integrity of architectural space. Computer technologies bring together bi-dimensional and three-dimensional languages of modeling and thus they help the procedure of movement of consciousness from the plane to volumetric images and back to the visual and mobile. They help to carry out the level-by-level analysis of the multilevel structure of an architectural reality in the mode of active dialogue. The process of interaction of consciousness with the model becomes accessible to studying. There appears an opportunity to manage this process with the aim of forming perception.

title CONTEXTUALIZATION AND EMBODIMENT IN CYBERSPACE
doi https://doi.org/10.52842/conf.caadria.2004.005
source CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 5-14
summary The introduction of VRML (Virtual Reality Markup Language) in 1994, and other similar web-enabled dynamic modeling software (such as SGI’s Open Inventor and WebSpace), have created a rush to develop on-line 3D virtual environments, with purposes ranging from art, to entertainment, to shopping, to culture and education. Some developers took their cues from the science fiction literature of Gibson (1984), Stephenson (1992), and others. Many were web-extensions to single-player video games. But most were created as a direct extension to our new-found ability to digitally model 3D spaces and to endow them with interactive control and pseudo-inhabitation. Surprisingly, this technologically-driven stampede paid little attention to the core principles of place-making and presence, derived from architecture and cognitive science, respectively: two principles that could and should inform the essence of the virtual place experience and help steer its development. Why are the principles of place-making and presence important for the development of virtual environments? Why not simply be content with our ability to create realistically-looking 3D worlds that we can visit remotely? What could we possibly learn about making these worlds better, had we understood the essence of place and presence? To answer these questions we cannot look at place-making (both physical and virtual) from a 3D space-making point of view alone, because places are not an end unto themselves. Rather, places must be considered a locus of contextualization and embodiment that ground human activities and give them meaning. In doing so, places acquire a meaning of their own, which facilitates, improves, and enriches many aspects of our lives. They provide us with a means to interpret the activities of others and to direct our own actions. Such meaning is comprised of the social and cultural conceptions and behaviors imprinted on the environment by the presence and activities of its inhabitants, who in turn, ‘read’ by them through their own corporeal embodiment of the same environment. This transactional relationship between the physical aspects of an environment, its social/cultural context, and our own embodiment of it, combine to create what is known as a sense of place: the psychological, physical, social, and cultural framework that helps us interpret the world around us, and directs our own behavior in it. In turn, it is our own (as well as others’) presence in that environment that gives it meaning, and shapes its social/cultural character. By understanding the essence of place-ness in general, and in cyberspace in particular, we can create virtual places that can better support Internet-based activities, and make them equal to, in some cases even better than their physical counterparts. One of the activities that stands to benefit most from understanding the concept of cyber-places is learning—an interpersonal activity that requires the co-presence of others (a teacher and/or fellow learners), who can point out the difference between what matters and what does not, and produce an emotional involvement that helps students learn. Thus, while many administrators and educators rush to develop webbased remote learning sites, to leverage the economic advantages of one-tomany learning modalities, these sites deprive learners of the contextualization and embodiment inherent in brick-and-mortar learning institutions, and which are needed to support the activity of learning. Can these qualities be achieved in virtual learning environments? If so, how? These are some of the questions this talk will try to answer by presenting a virtual place-making methodology and its experimental implementation, intended to create a sense of place through contextualization and embodiment in virtual learning environments.

summary (pdf file in greek)- With the aid of the acoustic simulation plate-form named « CAD-Acoustic » which is developed in the context of PhD and adapted on the AutoCAD system, this paper presents the halls acoustic results (RT60) of Elmia (Sweden) and Opera of Bordeaux (France) in relation to acoustic measurements and results of other acoustic simulation software (Odeon, Epidaure). In parallel, it presents geometrical simulations of the modelised halls’ acoustic behavior, such as the 3D reflections of the acoustic rays from selected surface, the 3D view of the materials’ arrangements through surfaces’ coloring, the measurement of the selected absorbing / reflecting surfaces in m2 and the individual or massive absorption coefficients’ assignment to the surfaces. Finally, with the aid of « CAD-Acoustic » the acoustic results are compared in a graphic manner in relation to the ideal acoustic rates, a presentation which is a kind of an “ architectural translation of the acoustic results” taking into account several architectural elements.

source Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 48-58
summary This contribution is devoted to the brief description of the basic directions and tendencies of researches of the laboratory of video systems MARCHI. In connection with development of hardware-software computer means and their practically absolute, not alternative application in the practice of architectural designing, nowadays (not always is proved) the sphere of application of the former traditional methods of physical modeling and their connection to the endoscopic methods has been narrowed. We consider some new probable directions of development of scientific and educational work within the framework of activity of our laboratory, allowing a more balanced approach to these problems. As we have discussed, our theoretical researches and practical works must reassume an existing non-standard and controversial situation in Russia, such as established substantial intellectual potentials in scientific- and methodological researches within study processes. In addition to that, what we can use are affordable and limited physical and financial recourses and capability for technical development of works for modeling perception in designing architectural and town planning space. These initiated searches in the field of non-standard thinking, derive from our contacts with EAEA colleagues. Below we will try briefly to explain our basic principles of work development. (To be clear, some time we dismiss references and notes into exact reports from our conferences supposing that interested colleagues may get further and detailed information from already published past events).

summary This research aims to develop a three-dimensional representation method for complex environmental systems based on the environmental impacts derived from actions or interactions amongst the elements of the studied systems and associated systems. It is a method for representing matrices in networks which contemplates the simulation of causes and effects and the visualization of interdependence links amongst the subsystems making them up and also amongst adjacent systems. The methodology includes the observation and study of an environmental system with the consequent formulation of a networked matrix and, finally, its modeling through a three-dimensional software. Both the elements and the interactions are represented as three-dimensional items with a shape, color, and size of their own. The practical result is a three-dimensional animation in which all the elements of the environmental system and their connections are represented.

summary With the introduction of the computer into different forms of digital applications in the design process, Mitchell strongly recommended a wider application of the new technology in the design process -- implying the mutual influence between physical architecture and the sketches, and between physical and digital models. Most important is the possibility of using computer aided design (CAD) to develop ideas in early design stage. During the developing idea stage, the traditional design process from sketching drawings to forming ideas has been transformed to a process where the idea directly proceeds to computer modeling. The aim of this approach is to tackle the above issues created by the introduction of computer technology, trying to produce the same possibilities during the computer modeling process as that in the cognitive behavior of sketching. Also, the designer usually realizes the abstract concepts with the aid of the 2D sketches and the 3D physical models; but between the traditional sketches and the models, a large degree of disagreement always exists. Therefore, this work aims to develop a new formula for employing digital media, which will enable the designer to envisage 2D sketches and computer models simultaneously. In this scenario, the designer can remain aware of cognitive behavior in sketching while constructing computer models.

summary Design visualisation is an essential aspect of virtually every form of design enquiry. The effects of potential environmental interventions may be simulated in order to gain the types of insights, which cannot be acquired easily from two-dimensional notations. Three-dimensional representations may be generated for very different reasons. The most direct form of design imaging is traditionally for the benefit of the designer him/herself, in order to test whether the working concepts offer fitting solutions to the complex array of design conditions such as context, programme and feasibility. Alternately, images may be generated for the benefit of communication, in order to offer insights into the expected workings of a particular proposal (possibly including alternatives). This may lead to greater understanding and possibly to reaching consensus amongst different ‘actors’ involved in the design and realisation process. In many cases the results of such visualisation studies contribute to ‘bridging the gap’ between the professionals and other parties involved more indirectly in design decision-making or the appraisal of the proposals. Designers can use distinctly different methods when going about such imaging procedures. Their choices for particular techniques may depend on their familiarity or the availability of certain media devices. Being confronted with new modelling and/or visualisation instruments can stimulate the interest in fresh approaches. In this respect, the design education environment can play an important role in not only teaching ‘proven’ applications to future designers, but also in creating a platform for the active development of innovative approaches to the design visualisation practices: education as a ‘laboratory’ for new insights and potentially a ‘breeding ground’ for the extension of the designer’s instrumentation. This contribution documents the experiences gained in some ten years within an educational application, involving active use of design driven media applications. The emphasis lies on the evolvement of techniques for eye-level imaging, whereby use can be made of different types of models: physical scale models as well as digital, virtual models. Changing attitudes towards dynamic and serial vision are considered, whereby storyboard approaches on the level of integral presentation are considered. By analysing a selection of cases and their underlying approaches an indication is given of the changing attitudes and combinations of multimedia techniques, which offer opportunities to design visualisation and communication.

summary The paper is a comparison of interface changes as a result of modern concepts and a new hardware development. It explains the notion ‘virtual’ and its application in a few generations of user interface. Modern interfaces are chained with simulation technology. The meaning of simulation is strictly related to the notions: possible, actual, potential force. All of them are ingredients of ‘virtual’. Finally interfaces bring to the point: what virtual is?

title Computer Visualizations in Planning
source eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary A wide range of visualizations have been developed and implemented as tools for urban simulations and visual impact assessment. These include: plans, diagrams, elevations, perspective sketches, renderings, modified photographs (photo renderings and photomontages), slide projections, scale models, movies, videotapes and computer graphics. In the last decade, graphical computer applications have proven to be an increasingly supportive tool in visualization and manipulation of graphical material. This study presents the state of the art of computer visualization in planning. More specifically, the use of web-based computerized visualizations for landscape visual simulation, with the aim to develop a system of visualization techniques as an aid to communicating planning and design scenarios for historically important landscapes and urban places, with particular attention to the city of Nablus in Palestine. This has led to the evaluation of possibilities and potentials of computer use in this field, and to the definition of the visual problems and challenges of the city of Nablus. This study will argue what extra one can draw from computerized visualizations, what is likely to be its impact on future planning and design research, and what this visualization experience really means for historical important locations as in Nablus. The study demonstrates that computerized visualizations can be a powerful tool in representing a cityscape in three-dimensions from different angels. Visualizations will allow better understanding of the components of the city, its landscapes, city features and the process of change. In this way it may provide new and better platforms for public participation in planning.

summary Solidere, a Lebanese joint-stock company, was created by government decree in 1994 to reconstruct Beirut city-centre. The company, a form of public-private partnership, has a majority share holding of former owners and tenants of city-centre property. Several projects are underway, including the redevelopment of Place des Martyrs, once the bustling heart of Beirut but badly damaged during the war. Urban planners in Beirut have recently developed a 3D computer model to visually describe the spatial characteristics of Martyr’s Square and its context, prior to inviting design proposals for an international competition. This paper describes issues pertaining to the development of the model to meet the needs of urban designers and town planners. It also considers potential future uses of the simulation, outlining areas for further research and development.

summary The following paper describes an ongoing research project whose goal is to define a scalable, hybrid production and deployment protocol (CIMSp) for the creation of virtual environments (VE). Ultimately, the aim is to establish a creative workflow and infrastructure that embodies architectural and urban design activity as practiced by the research unit. The objective of the present paper is to schematically outline the current state of the research and its practical and theoretical context for further development. A theoretical position will be stated which assumes that the content, tool, epistemological, and speculative realms are consubstantial (technoèsis). The practical endeavour is to create the informational and embodied temporal--spatial condition of possibility for the imaginative production of cultural artifacts. It must accommodate varying individual and collaborative forms and styles of making and no presumption of a self-enclosed and referential system is made. A critical position is particularly compelling when this production is immersed in technological modalities of making where information and embodiment are inextricably intertwined. CIMSp is based on the workflow from acquisition and creation to output and storage. The work environment is comprised of a select set of software applications and visualization technologies. Secondly, an XML-based content and information management system is under construction to ensure project quality control, rigorous documentation practices, and bi-directional knowledge feedback procedures to enable an effective and resource-full workflow. Lastly, scalability of output modalities for use in the design process and for final presentation from WWW deployment to a high-resolution collaborative work environment (CWE) is being developed. The protocol is a multiuser mode of creation and production that aims to transform the technologies and their interrelation, thus dramatically impacting the creative process and intended content. It is a digital production workflow that embodies intensive visualization criteria demanded by the end users. The theoretical and practical intention of CIMSp is to provisionally structure the collaborative creative process and enable a choreographed movement between the realms of the technologically mediated and made in the pursuit of significant digital content creation.

title Pedestrian Behaviour Modelling

summary This paper introduces a study of pedestrian behaviour modelling which incorporates ideas about agent-based systems and the traffic models based on the utility-maximization theory. The aim of this study is to examine the applicable scope of one of the basic assumptions in existing spatial behaviour models; the route with shortest distance maximizes the utility of each pedestrian’s travel. Although shortest-path models have been widely used in the field of Traffic management to predict routing behaviour, there can be seen a lot of erratic behaviour in urban areas, shopping migration behaviour for instance, which can not be explained by them. Thus, it is important to identify other possible influential factors on their utility maximization process in order to develop more explicable models of pedestrian movements. In this study, we implemented a simulation model using the shortest-path model as one of evaluation criteria of Genetic Algorithms (GA) to computationally emulate retail movements of shoppers in a big shopping centre and to test the accuracy of the model by comparison between the routes estimated by the model and actual trajectories of shoppers. This simulation system will be used as a platform for further modelling.

title Using Bayesian Decision Networks for Knowledge Representation under Conditions of Uncertainty in Multi-Agent Land Use Simulation Models
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN 1-4020-24088, p. 129-144
summary Land suitability analysis typically involves the assessment of the suitability of land units without knowing the future spatial distribution of land use. Traditional planning techniques have used “algebraic equations” to express land suitability as a weighted function of suitability scores across multiple criteria. However, the existing multi-criteria evaluation methods do not systematically account for uncertainty about the land use in adjacent and other cells. This paper proposes an alternative approach to land suitability analysis that does address the problem of uncertainty. In particular, Bayesian decision networks are suggested as a means of knowledge representation for agents in a multi-agent land use simulation system. Bayesian decision networks model the uncertainty in terms of probabilities specified in the network representing the expertise of specialists with respect to specific land uses. This paper discusses the approach and illustrates its use in the context of a retail agent.

title The Effectiveness of Design Guideline Regulations for Improving Streetscapes
source Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 21-27
summary Municipal governments or developers make design guidelines to create harmonious streetscapes in new towns. The regulations, however, are often based on arbitrary decisions without any empirical research. The present study employed a visual simulation system to test the effects of such physical features of the buildings as color, height, flatness of the building façade and its recess from the street on pedestrians’ impressions of the place. Thirty subjects were asked to rate their impressions of “order”, “simple”, and to evaluate the atmosphere after experiencing the simulated scenes. The results revealed some relations between the physical features and the pedestrians’ responses.
