title Discussing Photon-Mapping and Radiosity-Based Rendering Algorithms to Evaluate Qualitative Lighting Design in Contemporary Architecture
source Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 351-360
summary This paper attempts to determine the impact of different light propagation algorithm on visual perception of qualitative lighting design in contemporary architecture. Radiositybased and photon-mapping-based light simulation software is used in this empirical study as a “switch” to isolate the occurrence of the specific lighting phenomenon. Images generated by the two rendering software are graded using a subjective lighting metric. The results show varying visual response. This finding informs architects that general radiosity-based renderer might not be adequate to portray accurate computational representation of translucency, directional diffused reflection and caustics; lighting phenomena observed in contemporary architecture.

title An empirical approach to the experience of architectural space in VR - Exploring relations between features and affective appraisals of rectangular interiors
source Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 17-24

summary While it is well known that the built environment influences our emotional state, it is often difficult to attribute these experiences to particular properties. In fact, a systematic investigation of the relation between physical structure and emotional experience of architecture has not yet been done. Now virtual reality simulations facilitate a completely controlled variation of spatial properties and thus allow to empirically evaluate architectural hypothesises. The aim of the presented study was to investigate which factors from a component-based description of rooms significantly correlate with cardinal dimensions of experience. In a perceptual experiment experiental qualities of 16 virtual vacant rectangular interiors were rated in eight principal categories by 16 participants using the semantic differential scaling technique. The scenes were generated by a custom made graphics tool that also automatically generated the component-based scene descriptions. The data analysis revealed several interesting correlations between scene features and rated experience: For example, a preference for ratios near to the golden section could be observed for spatial proportions, which are not directly perceivable. Altogether, a set of five independent factors (openness, two room proportions, room area and balustradeheight) appeared to be effective for widely describing the observed variance of the averaged attributed experiental qualities. Our combination of realistic virtual reality simulations and psychophysical data raising methods proved to be effective for basic architectural research. It allowed us to demonstrate quantitative relations between physical properties from a component-based description of architectural space and its emotional experience.

title Architecture and the Stereoscopic Space of Experience
source SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary The conceptualization of architectural space is undergoing radical innovation. Architect-designers have become perceptual painters of animate experience through the use of digital stereoscopic technologies that permit the sensorial intensity of an experience of movement, color, form, and space. It is in creating such direct experiences for a client-user that this becomes defined as a necessary phase prior to the abstractive and pragmatic phases of design. This creates a new originating context -- a new paradigm -- to which a client-user will refer, thus creating an alternate model for design programming.

source SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary This paper explores an enormous potential of digital media in the area of morphology in industrial design, that goes beyond its extended and widespread possibilities of visualization and materialization. The visualization of the concepts that sustain the identity of our projects, eventhough they are invisible in finished products, can be explained and made evident through digital media. Intelligible aspects acquire perceptual shapes in order to make its apprehension easier. In this sense, we understand that virtual simulation is an important tool of cognitive mediation.

title A Critical Evaluation of Early Stages Software in its Capacity of Coping with Contextual Issues
source LOCAL VALUES in a NETWORKED DESIGN WORLD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Stellingwerff, Martijn and Verbeke, Johan (Eds.), (2004) DUP Science - Delft University Press, ISBN 90-407-2507-1.
summary In this paper we analyse critically early design stages software in its capacity of coping with contextual data at large (i.e. representing cultural, aesthetical context, etc.). We identified 5 categories of early stages software: geometry based graphic editors, evaluation architectural software, generative and shape-grammar based systems, evolutionary systems and other systems. Calling the object under creation during of the early stages a CAD conceptual model, we will investigate to what extend this software allows the architect to experience and represent the context in which a design is situated. Especially we will focus on its capacity to allow interaction, playful interaction on our way to the design. Designers, and particularly architects, interact with the local context similarly to interacting in a game: the context influences the users’ decisions, surprises them and causes permanent changes to their ways of thinking. On the other hand, architects permanently shape and reshape the context, and reduce the context to a protean point of reference. Such behaviour characterises creative thinking that is crucial for the early stage of design. The investigation led us to the conclusions that the effective interactivity with the context needs simple rules, a plain interface and data reduced as simple as possible, especially when interaction with the context is performed during the early stages of a design process. The findings can be used in organising computer environments for early-stage design.

summary Data representation architecture can be defined as the organizational, functional, experiential, formal, and media-technological order defining the interaction between data, representation, and user. This paper presents an interdisciplinary methodology to develop such architectures in order to significantly improve real time decision making in complex data environments. We have reported in some aspects of this work elsewhere. In this occasion, we will describe our working methodology based on complete interdisciplinarity, the design process and evaluation protocols. We will show work done for Finance and Network Monitoring. Our long-term goal is to design a new generation of data representation architectures that is applicable to diverse fields.

title The “Franziszeische Kataster” (land register) – Only a historial Map?
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary Franz I. of Austria that the legislative and technical hindrances were cleared away in order to commence with big changes. One cantruly say that it was due to his land tax patent from the 23rd of December 1817 that he founded the main land register of Austria andof the whole empire. The basic ideas of this patent are still valid today.This land register, named after it’s originator, was also said to be a “stabile” land register because the net profit rate, which wascrucial for the rating of taxation, was to be stabilized without giving consideration to higher productivity or diligence except to casesin which the fertility of the earth was destroyed by natural phenomenon.The land register was developed for the city of Vienna in the years 1819 to 1824. This land register of Vienna was scanned and digitized by the Urban Archaeology of Vienna. Since the launching of the “Kulturgüterkataster (Cultural Heritage Cadastre)“ in 1996, the individual municipal departments of the City of Vienna have developed a massive body of know-how regarding the various fields of interest. In particular, the inventoryingand evaluation of architectural objects as implemented by the City of Vienna could be easily adapted to other EU cities. It has alreadybeen suggested to initiate corresponding EU projects or participate in such.The long-time objective is an Internet portal. Based on the applications and competence developed in Vienna, the cultural assets of European metropolises could be digitised to present them in a novel forum. Lovers of culture, historians and urban planners would thus dispose of an instrument that renders urbanistic research much more efficient. Here, the “Franziszeischer Kataster“ could play a key role. Especially in the candidate countries in Eastern and South-eastern Europe, land surveying to this day would be unthinkable without this land register. A digital version of the register, could provide enormous support to the surveyor’s offices in the new Member States.

title The Dynamics of Physical Ambiences

doi https://doi.org/10.52842/conf.acadia.2007.174
summary This research proposes to support the reading of physical ambiences by the development of a representational technique which compiles, in a numerical interface, two types of data: sensory and filmic. These data are recorded through the use of a portable array equipped with sensors (Potvin 1997, 2002, 2004) as well as the acquisition of Video information of the moving environment. The compilation of information is carried out through a multi-media approach, by means of a program converting the environmental data into dynamic diagrams, as well as the creation of an interactive interface allowing a possible diffusion on the Web. This technique, named APMAP/Video, makes it possible to read out simultaneously spatial and environmental diversity. It is demonstrated through surveys taken at various seasons and time of the day at the new Caisse de dépôt et de placement headquarters in Montreal which is also the corpus for a SSHRC (Social Sciences and Humanities Research Council) research grant on Environmental Adaptability in Architecture (Potvin et al. 2003-2007). This case study shows that the technique can prove of great relevance for POEs (Post Occupancy Evaluation) as well as for assistance in a new design project.

title View from the Road: Environmental Simulation for the Fractal City of Rhine Ruhr
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. 43-47
summary Highway seems to be more an issue of traffic planning than of urban design. But the highway can be a very important factor for the modern city pattern. Highways shape the spatial form of the fractal city. The modern highway can define new cores outside and “interior edges” within the city. Seen as a planning tool, highways are the great neglected opportunity in city and regional design. The 1st Architecture Biennial, 1ab, taking place from May 2003 to July 2003 in Rotterdam, explores the creative potentials of modern highways worldwide. An international research team discovered the spatial functions of highways in modern agglomerations. This lecture will give an overview of the results of the worldwide analyses and the design projects that had been undertaken. Both authors are members of the German research team. The German team examined the A 42 running through the Ruhrgebiet, a former coal and steal area in western Germany. The Ruhr Area is converting from an industrially orientated region to an agglomeration of high technology and science. But the regional image remains the same due to the fact that the changes cannot be seen, neither physically, nor from the road. Here, the highway could be used as a catalyst supporting and structuring the spatial changes to make them more legible for the people of Rhine-Ruhr. The nature becomes the most important tool of highway design. Landscape forms a linkage between the different cities of the region. Together with the A 40 and other local highways the region becomes the most important (and largest) public space of the new Rhine-Ruhr. The highway seen as a work of urban art can be designed only from the perspective of the driving car.

summary This paper argues (i) that understanding of a place (especially in heritage environments) requires a level of cultural engagement and (ii) that virtual environments, in their typical current form, fail to provide such engagement. A proposed solution to the issue of cultural presence is to apply the interactive mechanisms commonly used in computer games (social agents, levels of interaction constraint, and task-based manipulation of artefacts) to virtual heritage environments. The hypothesis is that the resulting environment will allow for greater engagement and a more culturally immersive learning environment. Virtual environments also often lack techniques for evaluating the extent to which their design goals are achieved. A proposed secondary outcome is that designers and researchers of virtual environment can also use the above interactive mechanisms for the evaluation of user engagement without simultaneously interrupting the user’s feeling of engagement.

title Developing a Building Design Compiler that Frequently evaluates Building Design Performance within the Design Process
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
doi https://doi.org/10.52842/conf.caadria.2003.553
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 The proposed VLM system intends to facilitate the visual sustainability of urban natural landscape in China. In this system, GIS not only provides technologies for the inventory of landscape characteristics and the visual landscape evaluation, but also contributes to public or professional communication supporting through modeling and visualization. Therefore, GIS holistically acts as a fundamental support in this prototype system. Combining with psychophysical landscape evaluation (LE), photogrammetry and other digital 3D visualization, GIS provides quantitative data, scientific visualization and visual simulation for planning decision making.

source SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary Natural illumination can be considered as one of the major conditioner of the architectonical project, thus it demands an evaluation of it in the proposed architectonical object. Such evaluation can be achieved with graphic representations produced from computational simulations. However, those representations, images usually, deal with the difficulty to provide a better spatial comprehension since they do not allow people to visualize the tri-dimensional space due to it is a static and bi-dimensional representation. Once the interacting possibility can favour the observer spatial comprehension, this possibility was analyzed, creating a VRML environment to present a natural illumination simulation.

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.

summary DeTra is a research project that arose from the question: “How is it possible to assist students and professionals in architecture, dealing with structural details?” Our solution is a structural detail database, which assists by presenting example solutions of similar designs. This research was conducted in two overlapping parts. The first part of the research included the definition of a structure and a language to describe structural details—flexible enough to enable complex computer based queries, simple enough to be understandable. Major problems were the inclusion of vague terms, different meanings for the same word, and different words for the same fact. The second part was to create internet-based computer software, which utilizes the developed concepts and allows their evaluation. Thereby the system can be used with different access methods to the same data collection. This approach intends to present both standard detail examples and project-related detail examples. For that reason the structural connections will be presented including all available project data. The information includes texts, sketches, drawings, photos, animations, and the database description. Our implementation handles this content. According to the holistic presentation of the search results a strong tool for evaluation is given to the user.

summary This paper presents an updated evaluation of an experience of applying computer graphics, virtual reality and Internet resources in the teaching of technical graphics at the University of Brasilia, Brazil. It differs from a previous paper (Pratini, 2004) for the addition of an overview of the course, the context and the new teaching methodology. It is an extended, more detailed paper, which includes examples, and closes with some results of surveys on the didactic material and the methodology. Our motivation for this experiment is the fact that most of the students have a lack of previous knowledge on the basis of drawings, resulting difficulties in both understanding and visualizing technical drawings. In this experiment, we introduced VRML 3D modeling in addition to CAD and regular pencil-and-paper drawings study and practice. To support the learning of this broad knowledge not present in the technical graphics bibliography, we first provided a website with animations and virtual reality resources. Since 2003 we are providing a CD-ROM containing all the former website material which is updated each semester. At the present time, the CD-ROM contains almost all the needed didactic material and software for the one semester technical graphics course. This experience was intended to improve and to support learning in a way that motivates the students, young people who are used to play video and computer games. Classes, website and CD-ROM material were conceived to take advantage of computers´ interactivity and animated resources. The use of computers´ technology and new media to support the learning resulted a new methodology and several new unanswered questions.
