title	Modeling and Rendering Virtual Architecture by Using Fisheye-Panorama-Based Images and Lightings in HDR-Quality
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 172-174
summary	We use digitally made spherical panoramas as background for vr visualisation in architectural sceneries instead of stitched photographs (fisheye-based or serical-mirror-based). For this reason we had the idea to develop the first fisheye-based digitalscanning panorama-camera together with the manufacturer Spheron. The ultimate step in reaching optimal quality not only as a background but also as a source of lighting the background-image is taken as a HDR-image. The high-dynamic-range-technology was developed by the Californian scientist Paul Devebec. High dynamic photographs contain a broader range of information between the very bright zones down to the very dark zones - a lot more than “normal” photographs (digital and analogue), which are named LDR (low dynamic range in comparison to HDR). Some software-products in the field of cad-visualisation in virtual and augmented reality already enable the use of HDR-images and open a new field of controlling daylight and artificial light simulations with photographed backgrounds instaed of synthetic ones. The combination of digitally produced (scanned) spericalimages together with the use of HDR open a wide range of new implementation in the field of architecture, especially in combining synthetic elements in existing buildings, e.g. new interior elements in an existing historical museum).

title	Spatial Visualization of abstract Information: A Classification Model for Visual Spatial Design Guidelines in the Digital Domain
source	Swiss Federal Institute of Technology, ETH Zurich
summary	Visualization of abstract information refers to the design of graphical representations of information that has no simple relation to known concrete or physical forms. Designing visualizations of abstract information requires proposing visual representation for often a large body of data pants. determining a meaningful structure for the complex relations among them and suggesting a method for Interacting with this body of data. Spatial perception plays an Important role for cognitive processing when interacting with abstract information, slice spatially-organized Information can be accessed and operated on rapidly and effortlessly, especially when a spatial arrangement reveals the conceptual organization of Information. This thesis focuses on aspects of the spatial visual design of abstract information presented as computer-generated. dynamic and interactive images accessible through flat displays. The process of spatial visualization design is shaped by various factors including interactive, perceptual, navigational as well as organizational and metaphorical aspects and as such requires an interdisciplinary approach. Therefore, in researching spatial visual design. it is crucial to use methods facilitating the process of sharing competencies among different disciplines. In this thesis, we introduce a new classification model accommodating features important in designing effective spatial visualizations of abstract information. To enhance the effectiveness of spatial visualization, this model offers a holistic approach in classifiying spatial Visualization features. As part of the model, we analyze properties already used in architectural representation and other visual design disciplines for spatial presentations as well as investigate their potential usage in digital domains of abstract information. The process of spatial visualization In the digital environment is mostly based on the practical experience of a designer. and therefore the majority of spatial design know-how is heuristic in nature. Based on this assumption, we present a set of guidelines addressing the general problem of spatial design. The Spalial Design Classificahon Model, Visual Spatial Properties and Spatial Design Guidelines build an extendable infrastructure which becomes a first step towards augmenting the quality of spatial information design- We propose to use this infrastructure as a general blueprint for structuring the exchange of expertise in Interdisciplinary problem-solving processes.

title	ENVIRONMENTAL SIMULATION - NEW IMPULSES IN PLANNING PROCESSES
source	Proceedings of the 5th European Architectural Endoscopy Association Conference / ISBN 3-922602-85-1, 225 p.
summary	The 5th eaea Conference in Essen yielded four principal findings: • After having been limited to endoscopic picture and film renderings of analog scaled models, the european architectural endoscopy association (eaea) first bridged the gap to digital environmental simulations at this conference. It is not about a better or correct method, but a suitable method of representing the planned reality of a particular project using ways that make sense. The combination of digital and analog simulation media is a source of impetus to the user of both methods. The future belongs to the casespecific application and the numerous integration possibilities of the two different media. • In investigating the perception of pictures produced in both analog and digital form, it was ascertained that it was only after greater effort that the same level of pleasing qualities were achieved in the digital world, compared to pictures of analog scaled models. It seems that for many planning phases model-based pictures are superior to digital photos – with regards to economy, quality of representation and imaginative attributes. This last point seems to be especially important in the draft planning stages: the less sharp a picture is, the more remaining room for viewer interpretation there is. In particular, the high degree of precision characteristic of digital simulations no longer allows room for imagination in the individual viewer. • 3D environmental simulations will increasingly be incorporated with success in architecture and urban design courses at universities and colleges both here in Germany as well as abroad. The further spread of these techniques to other universities and colleges is desirable. Over and above application as a pedagogic tool, the use of these simulations by architects and city planners, private planning agencies and municipal planning administrators will also be in evidence in the future – for checking designs, for informing the involved parties, for establishing the decisions of government bodies, for marketing the project. • Also, the interactive use of endoscopic simulation facilities continually opens new fields of research – whether it be for registering subjective distance perception, whether it be for determining orientation possibilities in open spaces.

title	The IDD System: Interactive Didactic Diagrams for Electronic Education - A Method for Teaching Digital Modeling for the Representation of Architecture
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 160-163
doi	https://doi.org/10.52842/conf.ecaade.2002.160
summary	The Interactive Didactic Diagrams allows for the structuring of useful information in the didactics of Digital Representation of Architecture courses. It is based on the possiblity of analyzing a graphic process- the construction of an architectural element with 3D CAD software, as well as the execution of a particular geometric projection- while making use of interpolated frames. The interactive diagram permits a sequential control of necessary operations until a structure of a spacial-temporal sense is obtained. This is done in such a way as to permit the user to gradually make his/her way through the sequence of steps with the possibility of reviewing them until the process is fully understood.

summary	To make whole one image on screens that is generated by many computers and synchronization among computers, there is a need for a network software environment for multi-projector display system. Although the development costs increase for parallel programming for multi-projector display system, there is a possibility that the program cannot be executed at an enough speed since the network bandwidth might become a bottleneck. There are some software environments for that kind of multi-projector display system like Chromium that is latest version of WireGL (Humphreys, 2001&2002). WireGL is a kind of Client-Server Model, which one rendering server sends the data of rendering to many computers. While it can use the application without modification of source, it requires heavy network traffics. The other type of operating software is VR Juggler (Cruz-Neira, 2002), and CAVE Library that is a kind of Master-Slave Model. In the Master-Slave Model, every computer has same application programs to render the image that only keep the synchronization of rendering and events. But, these programs require a specialized skill and knowledge to modify the source of program for the certain rendering PC-Cluster system.

title	Physical and Virtual Tools: Activity Theory Applied to the Design of Groupware
source	Computer Supported Cooperative Work (CSCW), Kluwer
summary	Activity theory is based on the concept of tools mediating between subjects and objects. In this theory, an individual's creative interaction with his or her surroundings can result in the production of tools. When an individual's mental processes are exteriorized in the form of tools - termed objectification - they become more accessible to other people and are therefore useful for social interaction. This paper shows how our understanding of activity theory has shaped our design philosophy for groupware and how we have applied it. Our design philosophy and practice is exemplified by a description of the BUILD-IT system. This is an Augmented Reality system we developed to enhance group work; it is a kind of graspable groupware which supports cooperative planning. The system allows a group of people, co-located around a table, to interact, by means of physical bricks, with models in a virtual three-dimensional (3D) setting. Guided by task analysis, a set of specific tools for different 3D planning and configuration tasks was implemented as part of this system. We investigate both physical and virtual tools. These tools allow users to adjust model height, viewpoint, and scale of the virtual setting. Finally, our design practice is summarized in a set of design guidelines. Based on these guidelines, we reflect on our own design practice and the usefulness of activity theory for design.

title	Virtual Reality/Space Visualization in Design Education: The VR-Desktop Initiative
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 64-71
doi	https://doi.org/10.52842/conf.ecaade.2002.064
summary	Although virtual reality (VR) is a fast-growing field, utilization of its potential within an affordable environment in the early years of architectural education has been limited. Currently, we are in the process of exploring the educational potential of virtual reality in the creation and understanding of space as a set of dynamic volumes that can be experienced. The VR-Desktop initiative is an effort to bring the salient features of projection-based VR to second-year architecture students in a way that is more generally accessible than the many canonical, first-generation, projection-based VR systems. The VR-Desktop has been implemented in the teaching of the architectural design studio in the second year of a fiveyear curriculum, as part of the physical architectural studio. Through the VR-Desktop system in the studio, students immediately start working in an immersive environment. They create space by manipulating solids and voids while evaluating the anthropometric relations of the proposed solution. The students are able to study and test conceptual details in a virtual environment from the very beginning of their architectural design project. In order to assess student perception of the usefulness of various system attributes for diverse tasks, we have begun a usability study. Thirty-five surveys were collected from the students who had used the lab during the two semesters for which the two-screen system was available. Preliminary observations indicate that within the architectural context, virtual reality techniques involving depth perception can convey relevant information to students more efficiently and with less misrepresentation than traditional techniques. This paper suggests that full field of view, motion, stereoscopic vision, and interactivity are possible components of the 3D visualization techniques that are necessary to enhance architectural education

title	Architect and Structural Engineer in interactive design
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 386-389
doi	https://doi.org/10.52842/conf.ecaade.2002.386
summary	We are convinced that an interactive design process involving engineers and architects will create values to a project. Looking back there have been some obstacles, like a week’s time for exchange of drawings with traditional postal services; manual calculation methods, which could not be spoiled on loose grounds like architect’s sketches; different media – architect’s drawings and engineer’s numbers in tables; attitudes and traditional roles, implemented already in education. Today most of these obstacles can be overcome and we have made a test. We have used ArchiCad by Graphisoft and FEM-design by SKANSKA IT Solutions to test to make an interactive design. Our conclusions are that exchange of information, drawings and other documents is more or less routine in praxis, and it works almost instantly. Computers make calculation faster and easier for the engineer. Though we would wish to have software which manages to do more rapid estimations. Even simulations such as of loads on a structure are practically possible. By using model based CAD the data can be used for transferring quantities for calculations as well as visualization of the design as a platform for collaborate analysis. The technique is developed and usable but to gain acceptance and make use of it is also a matter of attitudes and of application activities in education.

title	Interactive Storytelling and Its Role in the Design Process

doi	https://doi.org/10.52842/conf.caadria.2002.151
summary	Projects of ever increasing complexity and size have incited the need for new and robust design methodologies and tools in an effort to manage complexity, lower costs, ascertain quality and reduce risk. Technology convergence through the growing availability of networked computers, rapid progress in Computer Aided Design (CAD) and information management have encouraged the undertaking of even more complex designs that demand high degrees of interaction, collaboration and the efficient sharing and dissemination of information. It is suggested that interactive storytelling and interactive design (Rafi and Karboulonis, 2001) techniques that use non-linear information mapping systems can be deployed to assist users as they navigate information that is structured to address localized needs as they arise. The design process is a collaborative effort that encompasses diverse knowledge disciplines and demands the management and utilization of available resources to satisfy the needs of a single or set of goals. It is thought that building industry specialists should work close together in an organised manner to solve design problems as they emerge and find alternatives when designs fall short. The design process involves the processing of dynamic and complex information, that can be anything from the amount of soil required to level lands - to the needs of specific lightings systems in operation theatres. Other important factors that affect the design process are related to costs and deadlines. This paper will demonstrate some of our early findings in several experiments to establish nonlinear storytelling. It will conclude with a recommendation for a plausible design of such a system based on experimental work that is currently being conducted and is reaching its final stages. The paper will lay the foundations of a possible path to implementation based on the concept of multi-path animation that is appropriate for structuring the design process as used in the building industry.

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	Modeling architectural design objectives in physically based space planning
source	Automation in Construction 11 (2) (2002) pp. 213-225
summary	Physically based space planning is a means for automating the conceptual design process by applying the physics of motion to space plan elements. This methodology provides for a responsive design process, which allows a designer to easily make decisions whose consequences immediately propagate throughout the design. It combines the speed of automated design methods with the flexibility of manual design methods, while adding a highly interactive quality and a sense of collaboration with the design itself. In our approach, the designer creates a space plan by specifying and modifying graphic design objectives rather than by directly manipulating primitive geometry. The plan adapts to the changing state of objectives by applying the physics of motion to its elements. For design objectives to affect a physically based space plan, they need to apply appropriate forces to space plan elements. Space planning can be separated into two problems, determining topological properties and determining geometric properties. Design objectives can then be categorized as topological or geometric objectives. Topological objectives influence the location of individual spaces, affecting how one space relates to another. Geometric objectives influence the size and shape of space boundaries, affecting the dimensions of individual walls. This paper focuses on how to model a variety of design objectives for use in a physically based space planning system. We describe how topological objectives, such as adjacency and orientation can be modeled to apply forces to space locations, and how geometric objectives, such as area, proportion, and alignment, can be modeled to apply forces to boundary edges.

doi	https://doi.org/10.52842/conf.acadia.2002.395
summary	The cyberPRINT is a fully immersive, interactive virtual environment that is being generated in rea-timebased on physiological data readings of a human body. In other words, the cyberPRINT is based oncreating interfaces between physical and digital spaces and between biology and informationtechnologies. The cyberPRINT is also an event, wherein a performer is connected to the cyberPRINTgenerator to create a self-sustaining feedback mechanism. Although using the body to electronicallydrive music and media events is not new, most of these works have paid little or no attention to thepotential of interactive 3D virtual environments. Nor have they been so technologically advanced,interdisciplinary intensive (involving architecture, choreography, modern dance, music, bioengineering,medicine and computer science), or architecturally focused as the cyberPRINT.This project covers a wide and fertile territory that goes from the very technical and design oriented tothe very theoretical and interdisciplinary. This paper is intended to (1) expand what has been alreadypublished about this project (Bermudez et al 2000a) and (2) establish potential areas for discussionbefore and after the performance

title	GenJam in Transition: from Genetic Jammer to Generative Jammer
source	International Conference on Generative Art
summary	GenJam, short for Genetic Jammer, is an evolutionary computation (EC) based software agent that models a jazz improviser. Recently GenJam has evolved away from its roots as an interactive genetic algorithm toward its current state as an autonomous generative system. GenJam has retained its chromosome-based representations and mappings, its intelligent selection, crossover and mutation operators, and its real-time interactive performance capabilities. However, it no longer needs any explicit representation of fitness, which arguably makes it no longer an EC system. This paper considers GenJam as a generative art system. Generative art produces “unique and non-repeatable events” that express a designer’s generating idea. The designer’s generating idea defines a species of events, represented in a genetic code. In music, these events could be individual notes, melodic phrases, even entire pieces. In GenJam the events are four-measure phrases, or “licks” in the jazz vernacular. The format for the genetic code, then, defines a species space from which unique individual events can be generated. Uniqueness is important in jazz because improvisation must be spontaneous and “new.” Hence, improvisation is tailor-made for the generative art paradigm, and in fact, one could argue that improvisation is, by definition, the purest example of generative art applied to music. In other words, generative music is improvisation, and GenJam is the Generative Jammer.

title	Evaluating the Use of a Web-Based Collaborative Interactive Digital Model (CollABITA) in Supporting the Urban Design Approval Process1
source	UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, III.1-III.15
summary	This research, after analyzing the Urban Development Approval Process in its functionalities and methodologies, is showing the key points at which the process might be supported by new computer technologies, and it establishes a web-based Collaborative Interactive Digital Model (CollABITA Model) that relates and facilitates the graphical representation of the urban design process with some elements of the methodological approach. The CollABITA Model will dramatically facilitate the idea of broadening public participation, and indirectly by this, also collaboration. This new web-based support tool, is focusing on how new Informative Computer Technologies can be used in order to have a more co-operative design process. By utilizing the enormous potential of Internet for informing the process, and software for visualizing its products, the Model will provide an effective support, which will be able to deliver information in various forms to the Designers, Developers, Decision Makers, Agencies and the final user (the Citizens). The Model is concerned with the big challenge of supporting the urban design approval process itself, by exploring different kind of visualizations and communication tools, rather than producing a guide for carrying out the design. CollABITA Model is based on the existent framework structure of the extranet tool already available. Then, more then those, CollABITA Model will try to solve, by adding technical and collaborative functionalities, those issues that are characteristics in the urban design process and that are not jet solved by using one of the software .

title	Support for collaborative design reasoning in shared virtual spaces
source	Automation in Construction 11 (2) (2002) pp. 249-259
summary	This paper discusses collaborative design, emphasizing the elaboration and transformations of a problem space, and the role that unstructured verbal communication and graphic communication can play in these processes. An asynchronous collaborative system, called the Immersive Discussion Tool (IDT), is introduced as a means for supporting productive design exchanges. IDT allows collaborators to reason about 3-D models over the Internet using view-dependent and view-independent diagrammatic marks, dynamic simulations, geometric design surrogates and text annotations. IDT relies on VRML to view the models, with an extensive Java-based interface driving the interactive behavior, including the construction and playback of graphical annotations, the management of threaded discussions, and the management of file input/output. The development and initial implementation of IDT has revealed the difficulty of constructing complex marks in a virtual 3-D space. Possible strategies for dealing with these problems are suggested.

title	Managing Design Knowledge with Mixed-Initiative Dialogue
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	This paper is based on ongoing work in developing interactive interfaces to formal methods for encoding design knowledge. It reports on the development of a shared graphical notation to support user interaction with design knowledge based on mixed-initiative. Mixed-initiativeprovides a model of interaction where both the designer and the knowledge formalism may share responsibility over decisions. The paper discusses how a formal visual notation can support the mixed-initiative mode for developing and managing formal design knowledge. The notation addresses on the dialogue problem between the user and a knowledge basedformalism and illustrates a model of interaction in which the user and the formalism can share and input data through a common shared resource, on a common shared task. The paper demonstrates the use of this notation in common decision tasks and the implications for seamless interaction with design support systems.

title	GenOrchestra: An Interactive Evolutionary Agent for Musical Composition
source	International Conference on Generative Art
summary	GenOrchestra is a project involving the Dipartimento d’Informatica and Conservatorio di Musica “N. Piccinni” in Bari. This project concern a Creative Evolutionary System, based on Evolutionary Computation (EC) techniques, applied to the field of western tonal music. With GenOrchestra a novel way to evaluate the produced tunes is presented: indeed we adopt a hybrid solution composed for two kinds of fitness functions. The first, called technique fitness, evaluates the consonance degree between melodic, harmonic and rhythmic sections, moreover, it defines how well the rhythmic paths is organized into a coherent musical event. The second fitness function called human fitness, determine how well the tunes are perceived from a human audience, like in a concert. This task is accomplished by presenting the tunes on the Internet and then gathering the surfers evaluations in a database from which the system take the final population scoring. This, coupled with a no limited musical primordial soup, makes GenOrchestra a promising eclectic artificial composer. The ultimate goal of this project, currently in progress, is the development of a very human-like composer, which can produce music in any musical genre, and which is able to show a “personal style”. Samples will be soon available at http://valis.di.uniba.it/GenOrchestra/samples.html

title	Interactive Tools for Collaborative Architectural Design
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	Today’s rapidly changing society is continuously developing towards an increased demand for multistakeholder knowledge and influence in the architectural planning and design process. Accordingly, we are working with developing and setting up a partner engaged collaborative design process. It includes active collaboration between users, external partners and designers, and visualizations in conceptual design and scenario building. My research is focusing on integrating visualization technology in theseprocesses by application of digital tools. We have developed a working prototype for an interactive design tool. The prototype is an extremely “easy to use” digital modeling tool called “ForeSite Designer.” With this tool one builds one’s own spatial environment with elements on a 2D surface.With one command the 2D layout is exported to a lit-up 3D/Virtual Reality world in the computer game “Half-Life”. ForeSite Designer has lately been used in a series of workshops together with external users. In these processes ForeSite Designer has played a crucial role as an arena of building spatially arranged concepts of future environments.

title	Can a Genetic Algorithm Think Like a Composer?
source	International Conference on Generative Art
summary	There has now been a substantial body of work utilising Genetic Algorithms (GA) for the purpose of musical composition. A common point of discussion is how far GA’s can simulate not just the musical output of human composers, but also the process of composing itself. This paper begins by discussing the suitability of using a GA for composition, and goes on to describe a generative music system (by the author), that utilises a domain specific, knowledge rich GA. The system acts on a supplied 2-bar musical phrase (up to 4 parts), and evolves musical fragments towards a supplied target. The aim is to provide interim points on the evolutionary path, which represents a ‘new’ musical ideas audibly based on the supplied fragments. The paper concludes that the system is able to model at least part of the creative process of composition, and is effective at producing musically successful results. (Audio download sources of its output are included to support this conclusion). The system was used to generate music included in an interactive installation work, exhibited at Brighton Arts Festival 2002, and other applications under developed that use the algorithm are discussed.
