title	XML Technologies and Geodata
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	Photogrammetry and Remote Sensing are very important methods for acquisition of geodata. During the previous decade, severalrevolutionary changes occurred in this area. Until the appearance of automated image analysis tools, it was necessary to measureselected points in the images given. At that time, it was much faster and even cheaper to get images of real world objects compared tothe time and money consuming process of manual analyses. So one tried to minimize this effort by measuring only characteristicpoints such as edges, break-lines, peaks and valleys and, for sure, a grid with a given grid step which was selected to meet the efforts.Lots of information in the images was neglected.Digital point matching algorithms and airborne laser scanning provide many new possibilities. The only restriction on spatialresolution is the one of the used sensors. Given a more precise image sensor, the matching algorithm will be able to match moresurface points; given a higher frequency laser scanner, more points can be measured of the same area. And those sensors get moreand more precise every day. Besides, those techniques allow for fast repetition which is necessary to create time series as a basis for4D modeling! However, this fact is accompanied by several problems concerning the capability of available computers. Some years ago, as the first ideas of 3D city models arose, it was very difficult to acquire the necessary data. Today the new sensors and methods have thenecessary capability, but we are not able to handle the available datasets efficiently, because of shortcomings in the past. In a time ofworld wide data exchange through the internet and global datasets, it is necessary to have efficient methods and algorithms tomanage the available data. There is a need for international, vendor independent data exchange and management standards that haveto be accepted and supported by the industry. This article is going to present several methods of data encoding using standardized data formats based on eXtensible Markup Language (XML). After an introduction to this kind of data encoding, two derived applications for management, storage and presentation of geodata are described. As XML data is written in text format, the datasets have the ability to become rather long.Therefore some promising methods to reduce the amount of data are introduced afterwards. XML documents are mainly used fordata exchange between databases. Therefore the capabilities of commonly used database systems for storage of geodata are describedin the end and current implementation results of the Institute of Photogrammetry and Remote Sensing (I.P.F.) are presented.

title	Performance Evaluation of 3D-Model CAAD Implementation in Dutch Architecture Firms
source	South Bank University [In cooperation with Hogeschool van Arnhem en Nijmegen - The Netherlands]
summary	The principal theme of this research is to provide information regarding the implementation of 3D Model CAAD, CAAD system which uses 3D Drawing Production Method (DPM) instead of 2D DPM This research is focused on its implementation in architecture firms and on justifies its performance and investment value. Principally there are two evaluations conducted in this research. First evaluation aimed to justify 3D-Model CAAD influence on design process and the second is investment evaluation which aimed to provide information for current and prospective user regarding their current and future investment on 3D-Model CAAD. The results of the evaluations are: 3D Model CAAD has improved performance through efficiency on time and cost of design process also improvement on design quality. However correlation between the use of 3D-Model C.4AD and better performance, while tested using Chi-Square Test, is not significantly. This fact indicates that there are some other strong factors to influence design performance. Second, 3D-Model CAAD, according the Importance-Performance Map is positioned at top right quadrant which categorised as 'keep the good work' which means it has good investment value.

title	A FRAMEWORK FOR BUILDING DESIGN PROCESS MODELING WITH PARAMETER-BASED DESIGN STRUCTURE MATRICES
source	In C. J. Anumba (Ed.), Innovative Developments in Architecture, Engineering, and Construction. (pp. 25-31). Rotterdam: MillPress
summary	Architecture/Engineering/Construction (AEC) industry is one of the multidisciplinary domains in which collaboration among related parties is utmost important. While the knowledge needed for building processes are distributed among the different participants from diverse disciplinary backgrounds, the product of their activities, i.e. the building itself, must be highly integrated. Despite the intense flow of information between design professionals, there is a lack of research to better understand and manipulate these flows. Furthermore, most of the current process modeling tools in the AEC industry do not enable analyses of iteration in the process and they represent the process at high levels with very little information at lower levels. In order to resolve the issues mentioned above, this paper introduces the use of parameter-based dependency structure matrix as a process modeling and system analysis tool for building design. The method reveals insights into the process structure, optimum sequence of parameter decisions, iterative cycles and concurrency in the process. A knowledge management framework for parameter-based DSM applications is proposed and the application of the framework is demonstrated through a real life building design problem.

summary	Digital visualization addresses representational challenges from within and without architecture. ‘Disciplinary’ digital visualization is used to explore, understand and communicate architectural information associated with the production of buildings. 3D modeling, rendering, animation and VR as well as the power of digital media to permit the seamless integration of various data types are unleashing completely new ways to display architecture. As digital power continues to increase and get cheaper, portability and wi-fi networks take root, and visualization work becomes even more main stream, we can expect growing changes in the way the design process is conducted, buildings are presented and documented, and the public and 3rd party’s demands from professional services. This demands a more conscious research/pedagogies aimed at developing new representation conventions.

title	Modeling of Activities: an approach to the virtual representation of human behaviors in architectural spaces tested in emergency units
source	International Journal of Architectural Computing vol. 1 - no. 3
summary	Despite the increasing interest in the functionality and humanization of architecture, there are few studies covering the occupation of buildings and methods to represent activities in spaces. This article explores new software for simulating and virtual modeling in order to facilitate the analysis and visualization of events in buildings. Of particular importance is programming the behavior of 3D-characters according to the probabilistic evolution of activities, and producing animations and interactive models. This approach was tested in a study of three emergency units of hospitals in Chile. Although a full integration of software was not possible, the process developed (in particular the subjective tours) demonstrated that the technique can provide new information about the functioning and spatiality of the units. In addition, it suggested operative and architectural improvements supporting the management and design of facilities.

title	Generation and visualization of 3D-city and facility models using CyberCity Modeler (CC-Modeler)
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The efficient generation of data for 3-D city models and their handling in Spatial Information Systems has become feasible. The derivation of this data from aerial and terrestrial images with semi-automated techniques constitutes the most powerful tool currently available to fulfill this task. Semi-automated object extraction has become a viable concept for the generation of 3-D city models. CyberCity-Modeler (CC-Modeler) has been developed with the aim of creating not only buildings, but also other objects pertaining to a city model efficiently and with a high degree of flexibility concerning the level of detail. In its commercial implementation, CCModeler has been confronted with a number of user requirements which needed to be observed. This led to some extensions in functionality, which are addressed in this paper: Geometrical regularization of buildings, editing functions for topology adjustment, integration of facades and other vertical walls and modeling of overhanging roofs. These extensions of the original concept make CyberCity-Modeler an even more powerful tool for 3-D city modeling.

title	The Level of Knowledge of CAD Objects within the Building Information Model
doi	https://doi.org/10.52842/conf.acadia.2003.173
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 173-177
summary	The first generation of CAD software depended on entity objects that were manipulated and interpreted by the user as meaningful graphics symbols. These entities only represented the geometrical properties of the architectural elements. With the present emerging generation of CAD systems, a new concept shifts a drawing-based model into a Building Information Model with the potential of modeling true architectural objects. Theoretically, these CAD objects will provide all related data to the designer describing the geometry, as well as any related data associated with how the object is actually used. The knowledge required to support an object should have structure to it. Different levels of knowledge need to be included, such as the geometrical information, which should be flexible enough to accommodate any type of shape and modification while keeping the object’s integrity as a unit and maintaining its relations to other objects. The CAD object concept, as remarkable as it is, might also have potential problems. It has some implications over the design process, as well as the architectural profession itself.

title	MetropoGIS: A City Modeling System
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	We report on a new system to generate photo-realistic 3D models of real cities. So far, we focus on the accurate geometric andradiometric modeling of man-made structures. The modeling process starts with a 3D block model obtained from aerial images, aerial laser scans or GIS data. This block model is further augmented with geo-referenced terrestrial images of the facades. Theterrestrial images are either captured using a mobile multi-sensor-platform or an off-the-shelf digital camera. The relative orientationof terrestrial images is calculated automatically and fitted towards the 3D block model with minimized human input using vanishingpoints. 2D image features like lines are extracted from the images and used to model 3D lines using line matching techniques. Theextraction of dense 3D point clouds on the facades is based on a hierarchical point matching strategy over multiple oriented images.Facades are found by robust fitting of plane hypotheses through these 3D line and point clouds. The introduced city modeling systemdelivers a fully 3D geographic information data set and is called MetropoGIS.

title	Computing And Manipulation In Design - A Pedagogical Experience Using Symmetry
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	The concept of symmetry has been usually restricted to bilateral symmetry, though in an extended sense it refers to any isometric transformation that maintains a certain shape invariant. Groups of operations such as translation, rotation, reflection and combinations of these originate patterns classified by modern mathematics as point groups, friezes and wallpapers (March and Steadman, 1974). This extended notion represents a tool for the recognition and reproduction of patterns, a primal aspect of the perception, comprehension and description of everything that we see. Another aspect of this process is the perception of shapes, primary and emergent. Primary shapes are the ones explicitly represented and emergent shapes are the ones implicit in the others (Gero and Yan, 1994). Some groups of shapes known as Semantic Shapes are especially meaningful in architecture, expressing visual features so as symmetry, rhythm, movement and balance. The extended understanding of the concept of symmetry might improve the development of cognitive abilities concerning the creation, recognition and meaning of forms and shapes, aspects of visual reasoning involved in the design process. This paper discusses the development of a pedagogical experience concerned with the application of the concept of symmetry in the creative generation of forms using computational tools and manipulation. The experience has been carried out since 1995 with 3rd year architectural design students. For the exploration of compositions based on symmetry operations with computational support we followed a method developed by Celani (2003) comprising the automatic generation and update of symmetry patterns using AutoCAD. The exercises with computational support were combined with other different exercises in each semester. The first approach combined the creation of two-dimensional patterns to their application and to their modeling into three-dimensions. The second approach combined the work with computational support with work with physical models and mirrors and the analysis of the created patterns. And the third approach combined the computational tasks with work with two-dimensional physical shapes and mirrors. The student’s work was analyzed under aspects such as Discretion/ Continuity –the creation of isolated groups of shapes or continuous overlapped patterns; Generation of Meta-Shapes –the emergence of new shapes from the geometrical relation between the generative shape and the structure of the symmetrical arrangement; Modes of Representation –the visual aspects of the generative shape such as color and shading; Visual Reasoning –the derivation of 3D compositions from 2D patterns by their progressive analysis and recognition; Conscious Interaction –the simultaneous creation and analysis of symmetry compositions, whether with computational support or with physical shapes and mirrors. The combined work with computational support and with physical models and mirrors enhanced the students understanding on the extended concept of symmetry. The conscious creation and analysis of the patterns also stimulated the student’s understanding over the different semantic possibilities involved in the exploration of forms and shapes in two or three dimensions. The method allowed the development of both syntactic and semantic aspects of visual reasoning, enhancing the students’ visual repertoire. This constitutes an important strategy in the building of the cognitive abilities used in the architectural design process.

summary	This study describes statue in the early phase of design, the approach taken by its conceptual development and manipulation. And on the developing digital tools provide a computational support for the process of indexing and retrieving. The digital modeling also addresses specifically architectural programming, adjacent relationship between the building element and articulation in designing. The overall in building mass development starting with reasoning of the conceptual model in early phase try to find evocative cases to help designer thinking. And finally discuss some issues and challenges of artificial intelligent. The research for representing designer’s creativity and searching solution provide another way to generate an articulating conceptual model. The integration approach of research starts with the pure case-based and rule-based reasoning system to help designer generate more understandable and creative product in the architectural design application.

title	Developing a Building Design Compiler that Frequently evaluates Building Design Performance within the Design Process
doi	https://doi.org/10.52842/conf.caadria.2003.553
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 553-566
summary	This paper demonstrates an experience in the development of a design performance evaluation system that can frequently evaluate building design performance within the design process in a real-time manner. The evaluation system, that we call "design compiler," is composed of several modules such as a front-end component-based CAD engine, a knowledge base, and a set of design agents. The notion of the design compiler is quite similar to a compiler for computer programming such as a C compiler. While a computer programmer compiles a set of programming codes to check compiling errors during the implementation of a software system, an architectural designer can 'compile' his/her intermediate design product to evaluate design errors during the design process. The compilation can be done immediately at any level or any time during the design process in a real-time manner. We expect that this compiling process will dramatically increase design feedbacks, and thus result in a better design product. Further research issues that have been identified at the end of the research include increasing the modeling capability, extending to multi-story building representation, developing various design agents, exploring better ways to request and manage design knowledge, and supporting design collaboration.

summary	A decade ago, Bill Mitchell wrote “Chroniclers of our era may one day write ‘What was computer-aided design?’ To them, it will just be design.” Because of the proliferation of digital tools for design, we are rapidly forgetting that there was ever design before computing. Ask an undergraduate student to describe the design process. There is a good chance that the student will mention using CAD and 3D modeling. Ask a contractor how to practice the profession of building.

title	A Discursive Grammar for Customizing Mass Housing - The case of Siza´s houses at Malagueira
doi	https://doi.org/10.52842/conf.ecaade.2003.665
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 665-674
summary	The ultimate goal of the described research is a process for mass customizing housing based on computer-aided design and production systems. The current goal is the development of an interactive system for generating solutions on the Web based on a modeling approach called discursive grammar. A discursive grammar consists of a programming grammar and a designing grammar. The programming grammar generates design briefs based on user data; the designing grammar provides the rules for generating designs in a particular style, and a set of heuristics guides the generation of designs towards a solution that matches the design brief. This paper describes the designing grammar using Siza´s houses at Malagueira as a case study.

title	DESIGN AGENTS IN 3D VIRTUALWORLDS
source	IJCAI03 Workshop on Cognitive Modeling of Agents and Multi-Agent Interaction, R Sun (ed), IJCAI, Acapulco, pp 92-100.
summary	Design agents are rational agents that monitor and modify elements of a designed environment. Special characteristics of design agents include the ability to reason about patterns and concepts, and the ability to act autonomously in modifying or changing the design to achieve their own goals. 3D Virtual Worlds are multi-user distributed systems that provide a designed environment and a closed world environment for studying design agents in a multiagent system. We present a model for a design agent reasoning process and a model for constructing a memory of the agent’s knowledge and interaction with a virtual world. The reasoning process includes sensation, perception, conception, hypothesizing, and planning a sequence of actions. Each agent has a constructed memory: a dynamic and changing view of the designed world that is determined by the agents sense data and reasoning. The agents construct and maintain a representation of the relevant objects in the world using a Function- Behavior-Structure formalism in order to reason about the intended and actual functions of the designed objects in the world. We have implemented this agent model by extending the Active Worlds platform so that each object in the 3D world can have agency. We illustrate the model with a door agent and a multi-agent room that reason about the use of the 3D world.

summary	The incorporation of virtual technologies to the learning process in architectural design is still incipient, using graphic software mainly as a rendering tool late in the curriculum. This paper presents an experience carried out with first year studio students, at the School of Architecture of the University of Chile, in which the intention is to incorporate virtual learning as part of the process spatial modification thinking. Through the use of Form Z, friendly software to learn for beginners, applied for simple extrusions, geometric transformations as translation, rotation or scaling, and the transformation of geometries and proportions through the handling of topological levels of polygonal objects. Through increasingly complex exercises we developed an effective complement of a traditional design methodology.

Related visualization leads to the exploration and comprehension of shapes. Exemplification can be seen in the verification for proofing or documentation of as-built models, such as paper architecture, process modeling, furniture, partitions, and construction details. The influences on architecture reveal issues related to pedagogical exploration, interdisciplinary exploration, reality management, and visual detail and structural detail.

summary	The research project in progress in the School of Architecture at the Izmir Institute of Technology includes documentation and reconstruction (by 3D modeling in electronic media) of damaged and lost early modern buildings in the Izmir region. The research aims to analyze the differences between Izmir modern buildings and Universal Modern Style, and preserve information on architectural heritage for future generations. The project is at the phase of developing an interactive web-based historical database (HizmO) that includes data (information, images, technical drawings, VRML models) and visualization of the findings. This database aims to be a pioneer in Mediterranean Region for exhibition of relations between traditional architecture (especially Mediterranean locality) and modernism, and organization of a network and off-campus learning activity for Mediterranean architecture that serve as a guide for students, researchers and architects. This paper aims at introducing this research and discussing the application of the database “HizmO,” its aims and potential effects on education in architectural history.

title	IMPROVING NEURAL NETWORK MODELS OF PHYSICAL SYSTEMS THROUGH DIMENSIONAL ANALYSIS
source	Journal of Applied Soft Computing 2(4): 283-296.
summary	The paper presents a technique for generating concise neural network models of physical systems. The neural network models are generated through a two-stage process. The first stage uses information embedded in the dimensions or units in which the data is represented. Dimensional analysis techniques are used initially to make this information explicit, and a limited search in the neural network architecture space is then conducted to determine dimensionless representations of variables/parameters that perform well for a given model complexity. The second stage uses information available in the numerical values of the data to search for high-level dimensionless variables/parameters, generated from simple combinations of dimensionless quantities generated in the first stage and which result in concise neural network models with improved performance characteristics. The search for these high-level dimensionless variables/parameters is conducted in an enhanced representation space using functional link networks with flat or near flat architectures. The use and effectiveness of the technique is demonstrated for three applications. The first is the design and analysis of reinforced concrete beams, which is representative of the class of problems associated with the design and analysis of composites. The second is the classical elastica problem, for predicting non-linear post-buckled behaviour of columns and the third, the analysis of a bent bar under a specified combination of loads.

summary	Digital Design is not only the title of the 21st eCAADe conference 2003 in Graz but also one of the main keywords in Architectural Education nowadays. Information Technology has managed to influence all fields of the “architectural process” and has developed straight from the calculation tools of the engineers over the CAD drafting boards of big architectural firms to every architectural professional and student. This process was incredibly quick in terms of the architectural chronology but very slow in terms of architectural education at universities (at least in Austria). Not very long ago it was sometimes forbidden to deliver CAD drawings for design projects at our faculty. In fact, the early experiments in using the computer in the design process quite often failed because of the restrictions of the available (and affordable) hard-and software. Today, even our first year students start some of their earliest design experiences quite naturally with the computer. However, there are still many questions to be answered and maybe some new questions to be asked in the relationship between architectural design and the computer. Architectural design is mainly a “game of imagination” and today computer tools start to enhance and support the architects visions after a longer period where they were often reduced by the limitations of the tools. Still, there are many different ways to design because every designer has a different approach towards architectural design and there is no such thing as “the perfect digital design tool” for everyone. We hope that this conference with all the different approaches documented in this book plays a major role in the discussion and development of all these aspects and brings us “one step further”.
