summary	The functions supported by commercial CAAD software are drawing, construction and presentation. Up to now few programs supporting the creative part of architectural problem solving have become available. The grand hopes of symbolic AI to program creative architectural design have been disappointing. In the meantime, methods called referred to as New AI have become available. Such methods includegenetic algorithms (GA). But GA, though successfully applied in other fields of engineering, still waits to be applied broadly in architectural design. A main problem lies in defining function in architecture. It is much harder to define the function of a building than that of a machine. Without specifying the function of the artifact, the fitness function of the design variants participating in the survival game of artificial evolution remains undetermined. It is impossible to fully specify the fitness function of architecture. The approach presented is one of circumventing a full specification through dividing labor between the GA software and its user. The fitness function of architectural ground plans is typically defined in terms only of the proportions of the room to be accommodated and certain topological relations between them. The rest is left to the human designer who interactively intervenes in the evolution game as displayed on the screen.

title	Spatial multimedia and virtual reality
source	London: Taylor & Francis
summary	The intersection of two disciplines and technologies which have become mature academic research topics in the 1990s was destined to be a dynamic area for collaboration and publication. However, until now no significant book-length treatment of the meeting of GIS and Virtual Reality has been available. This volume puts that situation to rights by bringing these together to cement some common understanding and principles in a potentially highly promising area for technological collaboration and cross-fertilisation. The result is a volume which ranges in subject matter from studies of a Virtual GIS Room to Spatial Agents, and from an Environmental Multimedia System to Computer-Assisted 3D Geographic Education. All the contributors are well-known international scientists, principally from the computational side of GIS. It will be a valuable resource for any GIS researcher or professional looking to understand the leading edge of this fertile field. ------------------------------------------------------------------------

title	THE EXPERIENCE OF SPACE IN FULL-SCALE MODELS AND VIRTUAL REALITY
source	Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 67-74
summary	Do we experience the size and character of virtual spaces in the same way as real spaces? What impact has the meaning of a space, i.e. furniture and other clues to the use of a space, on our experience of it? This paper describes an experiment where the participants could navigate through a room, first on desktop-VR, then in full-scale VR (in a CAVE) and finally in a full-scale model. In a first phase the room was empty and only defined through walls, windows and doors. Later on furniture was added as well as colors and textures. The experiment was a pilot study and threw light on some questions which we intend to develop in further investigations. It showed that the participants used building components like doors and windows and furniture in the presentation on desktop VR for their estimation of the size of the room. In the CAVE and in the full-scale model the participants' bodies were the measure for their estimations. The experiment also hinted at that color and texture had an impact on the experience of size.

title	Der Bleistift im 21. Jahrhundert. Das architektonische Entwerfen in interaktiven VR Umgebungen. (The pencil in the 21th century. The architectural design process in Virtual Environments)
source	IAO Forum Architektur im Informationszeitalter, FhG Stuttgart, 21.-22.4.1999, proceedings, chapter 7, 10 p.
summary	In the very young discipline of Virtual Reality Applications only a few reports are available about using this technology for periods longer than in experimental setups. This paper describes experiences made during five years of usage of Virtual Reality (VR) in educational training for architects. About 100 different people were working with our systems during this period. Three programs were developed at Bauhaus University with the aim of teaching architectural students to design in three-dimesional environments. The first program called voxDesign is based on the metaphor of voxels. The second program, planeDesign, uses rectangualar planes to describe room-like situations. An other program vram for the user orientated description of flexible and own interfaces and environments is current under construction, a first verson is presented at the international computer exhibition ìCeBitî in 1999. All programs force the users to design in a 1:1 scale, that means that the design and the feedback actions are coupled in an embodied way. A real walking metaphor is used for navigation. The experiences made by users are explained too.

summary	In the very young discipline of Virtual Reality Applications only a few reports are available about using this technology for periods longer than in experimental setups. This paper describes experiences made during four years of usage of Virtual Reality (VR) in educational training for architects. About 100 different people were working with our systems during this period. Two programs were developed at Bauhaus University with the aim of teaching students in architecture in three-dimensional sketching. An other program for free and own interfaces and environments is currently under construction and will be presented at the international computer fair "CeBit" in 1999. The first program called voxDesign is based on the metaphor of voxels. The second program, planeDesign, uses rectangualar planes to describe room-like situations. All programs force the users to design in a 1:1 scale, which means that the design and the feedback actions are coupled in an embodied way. A real walking metaphor is used for navigation. The experiences made by the students are explained too.

title	Immersive Redlining and Annotation of 3D Design Models on the Web
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 81-98
summary	The Web now enables people in different places to view three-dimensional models of buildings and places in a collaborative design discussion. Already design firms with offices around the world are exploiting this capability. In a typical application, design drawings and models are posted by one party for review by others, and a dialogue is carried out either synchronously using on line streamed video and audio, or asynchronously using email, chat room, and bulletin board software. However, most of these systems do not allow designers to embed annotations and proposed design changes in the threedimensional design model under discussion. We present a working prototype of a system that has these capabilities and describe the configuration of Web technologies we used to construct it.

title	Development of an Interactive Simulation System for Environment-Behavior Study
source	Simulation of Architectural Space - Color and Light, Methods and Effects [Proceedings of the 4rd European Architectural Endoscopy Association Conference / ISBN 3-86005-267-5] Dresden (Germany), 29 September - 1 October 1999, pp. 36-49
summary	An important recent development in the simulation techniques was the changes in the mode of presentation: from passive mode to active one. It is now possible to present an image according to the observer’s voluntary movement of body and head by means of a head-mounted display. Such interactive simulation system, which allows people to observe what they like to see, is suitable to study environmental perception, because active attention is essential to manipulate enormous information in the environment. The present paper reports two case studies in which an interactive simulation system was developed to test psychological impact of interior and exterior spaces: the case study 1 intended to clarify the effect of the disposition of transparent and opaque surfaces of a room on the occupants’ „sense of enclosure“, the case study 2 intended to make clear some physical features along a street which are influential for changing atmosphere. In addition to the empirical research, an attempt to develop a new simulation system which uses both analogue and digital images is briefly reported, and a preliminary experiment was conducted to test the performance of the simulation system in which such movable elements as pedestrians and cars generated by real-time CG were overlaid on the video image of a scale model street.

title	The Java 3D API and Virtual Reality
source	IEEE Computer Graphics and Applications, May/June
summary	Java 3D proves a natural choice for any Java programmer wanting to write an interactive 3D graphics program. A programmer constructs a scene graph containing graphic objects, lights, sounds, environmental effects objects, and behavior objects that handle interactions or modify other objects in the scene graph. The programmer then hands that scene graph to Java 3D for execution. Java 3D starts rendering objects and executing behaviors in the scene graph. Virtual reality applications go through an identical writing process. However, before a user can use such an application, Java 3D must additionally know about the user's physical characteristics (height, eye separation, and so forth) and physical environment (number of displays, their location, trackers, and so on). Not surprisingly, such information varies from installation to installation and from user to user. So Java 3D lets application developers separate their application's operation from the vagaries of the user's final display environment. The Java 3D application programmer's interface (API) provides a very flexible platform for building a broad range of graphics applications. Developers have already used Java 3D to build applications in a variety of domains including mechanical CAD, molecular visualization, scientific visualization, animation previews, geographic information systems, business graphics, 3D logos, and educational offerings. Virtual reality applications have included immersive workbench applications, headtracked shutter-glass-based desktop applications, and portals (a cave-like room with multiple back-projected walls).

title	Virtual Reality Meets Telematics: Design and Development of the Infinity Room
doi	https://doi.org/10.52842/conf.ecaade.1999.466
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 466-472
summary	The paper presents the findings of three years of experimentation in the use of compressed videoconferencing in international virtual design studios. Based on these findings, the authors elaborate on the development of a new videoconferencing interface: "The Infinity Room". The Infinity Room is a design studio space containing a floor-to-ceiling rear projection screen wall that conceals a dark room equipped with 5 video cameras and 4 video projectors that reproduce, on one-to-one scale, the images captured in a similar installation at a remote location. Operationally, the video cameras feed a computer that eliminate image redundancies, codes all the sources into a single entity and sends it as a compressed video signal to a remote computer that decodes and decompresses the images for synchronized delivery through the video projectors. The tiling effect of 4 synchronized and fully interactive video images creates the illusion of an adjacent room. The paper describes the design parameters used in the development of the Infinity Room and elaborates on the technology that makes it feasible. Requirements and constraints on physical space, hardware, software, and networking are discussed. The paper ends with conclusions that highlight the technical feasibility of building a small-scale prototype.

source	InterSymp-99[International Conference on Systems Research, Infomatics and Cybernetics/ISBN:0-921836-75-9] Baden-Baden(Germany), August2-6, 1999, pp. 39-47
summary	This paper describes our current work in the development of a collaborative design meeting environment which includes hardware and software. It attempts to support the design collaboration in face-to-face meetings, instead of collaboration in Cyberspace. Pinup walls, a meeting table, white boards are metaphors on the proposed system. Digitized design information, CAD drawings, CG pictures or movies and other documents could be accessible to members sitting for testing, simulating, evaluating design ideas or concepts on the projected video screen using installed program modules or off-the-shelf application programs. They could concentrate on discussing design issues, without interruptions caused by looking for some lost information and preparing design models or documents at their desks.

title	CAD Interfaces to the ARROW Manufactured Product Server
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 1-11
summary	The UK national project ARROW (Advanced Reusable Reliable Objects Warehouse) provides an Internet based framework through which it is possible to identify any of a range of manufactured products meeting specific design criteria. This open framework (based upon the IAI's IFCs) provides a mechanism for users to search for products from any participating manufacturer or supplier based both on specific attributes of a product or on any of the textual descriptions of the product. The service returns the closest matching products and allows the user to navigate to related information including manufacturer, suppliers, CAD details, VR displays, installation instructions, certificates, health and safety information, promotional information, costings, etc. ARROW also provides a toolkit to enable manufacturers and suppliers to more easily map and publish their information in the format utilised by the ARROW system. As part of the ARROW project we have examined the ability to interface from a design tool through to ARROW to automatically retrieve information required by the tool. This paper describes the API developed to allow CAD and simulation tools to communicate directly with ARROW and identify appropriate manufactured information. The demonstration system enables CAD systems to identify the closest matching manufactured product to a designed product and replacing the designed product with the details supplied by the manufacturer for the manufactured product as well as pulling through product attributes utilised by the design application. This paper provides a description of the ARROW framework and issues faced in providing information based upon standards as well as containing information not currently modelled in public standards. The paper looks at issues of enabling manufacturers and suppliers to move from their current world-view of product information to a more data-rich and user accessible information repository (even though this enables a uniform comparison across a range of manufacturer's products). Finally the paper comments on the likely way forward for ARROW like systems in providing quality information to end users.

summary	By november 1996, the state telecomunication company called for a national booth design contest. The idea was to use the awarded design shortly as part of the renovation of the public phone service. Gruppo MDM won the design contest and was contracted to do the manufacture technical drawings and a prototype which was tested during 1997. By 1997, an international bid was held, including the awarded project. Gruppo MDM was contracted for the follow up of the manufacture process, including research of suppliers worldwide, materials arriving on time with the quality required, verifying local suppliers with deadlines and quality controlls according to the specifications.

title	Interdisciplinary Collaboration in the Virtual Design Studio Design Studio
source	Proceedings of the 17th Annual EAAE Annual Conference, Plymouth UK
summary	Drastic changes in technology and economics currently impact common working structures. Moreover, a fundamental move of western societies from industrial and service oriented societies to information oriented societies can be observed. Like others, the AEC industry is also exposed to the challenge of these fundamental changes, not only regarding an ever growing stock of information on building components and materials, but also because of new methods of collaboration to be applied by all participants. As a result, integrating domain specific knowledge into the design process and conversely, conveying design intentions to domain experts, is meaningful in a constantly growing scale. Utilising advanced technology, a twofold approach in research and education, undertaken at the Institut für Industrielle Bauproduktion (ifib), University of Karlsruhe, is the basis of efforts to create and develop integrating methods of collaboration into the design and planning process. In addition, the integration of AEC practitioners (investors, users, designers, engineers) in the education process provides both drastic changes in the fields of design and construction education of students and a promising approach for life long learning. The focus of this paper is to present the current state of work and to report on experiences gathered during several Virtual Design Studios (VDS) in which multi-disciplinary participants from various Universities and backgrounds were involved. Platforms for the activities are World Wide Web based applications as well as animations, VR, CAD and video conferencing.

summary	This paper describes the developments of the CUMINCAD database since 1999 when it was first presented and some statistical information, how the service is being used. CUMINCAD started as a bibliographic database storing meta information about CAADrelated publications. Recently, full texts are being added. The process of creation of electronic copies of papers in pdf-format is described as well as decisions which were taken in this context. Over the last two years 20.000 users visited CUMINCAD. We present a brief analysis of their behavior and interaction patterns. This and the forthcoming possibility of a full-text-search will open up a new perspective for CAAD-research.

summary	The city of Bilbao has suffered in the last decade a deep transformation. After a glorious industrial past, Bilbao was in 1990 a depressed city, and the strategies necessary to transform an industrial city into a service capital were no simple due to the high level of pollution and unemployment rate. The "Bilbao Metropoli-30" Association was created to coordinate the synergetic action of all the involved institutions: City Hall, Basque Country and Spanish Governments, financial institutions, transport companies, airport and port, etc. But it was also necessary the acceptance of the public opinion to recover the illusion and the lost pride of the city. The desolated social scene was not adequate for revolutionary designs like the winding Frank Gehry's Bilbao Guggenheim Museum, or the cavernous Norman Foster's underground. This work pretends to show the means and strategies, especially computational, that allowed the transformation of Bilbao with an enthusiastic citizen support.

summary	The solutions that allow us to attend the potential exigencies planned for a territorial administration, oblige us to establish an informatizated step, performed with a group of logical tools, supported in the corresponding data bases. This means to establish an Information System who integrates basic data to activities and own resources, being a fundamental aspect of these Systems their capacity to synthetisize the dinamic of phenomena that reflect and several parameters that are the base to analyse this. Urban and Rural real estates (cadastral register) are elementary territorial unities whose integration, complemented with structural elements of a localization area, constitute the continuous of spatial information with the most degree of resolution. Trying as "variables” all physical, economical and juridical circunstances, this continuous of information in transformed in an extraordinary and interesting product, which can be potentiate if we include the Geographic Information System (GIS) concept, resulting of adding digital cartographic data bases to attributes and literal characteristics of elements stored in alphanumeric ones. The reason of this article is to divulge the Territorial Information System set up in the Cadastral Office of the City Hall of Montevideo, based on GIS technology, emphatizying the utility it produces in so large applications as: to investigate land occupation and property distribution, to planify and optimize resources and services, to act as a fundamental support to elaborate thematic cartographies, to serve as a detailed and precise support for urbanism, service flows and territorial ordenation and all other products issued for the own implantation philosofy, constituted with an open structure where the mentioned Office isn’t the only user.

title	What's Real About Virtual Reality
source	IEEE Computer Graphics and Applications, Vol. 19, no. 6, Nov/Dec, 27
summary	As is usual with infant technologies, the realization of the early dreams for VR and harnessing it to real work has taken longer than the wild hype predicted, but it is now happening. I assess the current state of the art, addressing the perennial questions of technology and applications. By 1994, one could honestly say that VR "almost works." Many workers at many centers could doe quite exciting demos. Nevertheless, the enabling technologies had limitations that seriously impeded building VR systems for any real work except entertainment and vehicle simulators. Some of the worst problems were end-to-end system latencies, low-resolution head-mounted displays, limited tracker range and accuracy, and costs. The technologies have made great strides. Today one can get satisfying VR experiences with commercial off-the-shelf equipment. Moreover, technical advances have been accompanied by dropping costs, so it is both technically and economically feasible to do significant application. VR really works. That is not to say that all the technological problems and limitations have been solved. VR technology today "barely works." Nevertheless, coming over the mountain pass from "almost works" to "barely works" is a major transition for the discipline. I have sought out applications that are now in daily productive use, in order to find out exactly what is real. Separating these from prototype systems and feasibility demos is not always easy. People doing daily production applications have been forthcoming about lessons learned and surprises encountered. As one would expect, the initial production applications are those offering high value over alternate approaches. These applications fall into a few classes. I estimate that there are about a hundred installations in daily productive use worldwide.

summary	In the development of intelligent computer aided design systems, three important issues need to considered. These issues are: how to support the generation of product concepts using evolutionary computation techniques; how to use intelligent databases and constraint management systems for detailed exploration of product embodiment; and how to integrate rapid prototyping facilities for product evaluation. In this paper, we present a brief review of knowledge based design and evolutionary design and discuss ways of integrating both in the development of a generative design system. Based on this review, we present the model and its applications of a generative design system utilizing a number of AI and evolutionary computation techniques. This generative design model is intended to provide a generic computational framework for the development of intelligent design support systems.

title	Using Computer Game to Develop Advanced AI
source	Computer, 34 (7), July pp. 70-75
summary	Although computer and video games have existed for fewer than 40 years, they are already serious business. Entertainment software, the entertainment industry's fastest growing segment, currently generates sales surpassing the film industry's gross revenues. Computer games have significantly affected personal computer sales, providing the initial application for CD-ROMs, driving advancements in graphics technology, and motivating the purchase of ever faster machines. Next-generation computer game consoles are extending this trend, with Sony and Toshiba spending $2 billion to develop the Playstation 2 and Microsoft planning to spend more than $500 million just to market its Xbox console [1]. These investments have paid off. In the past five years, the quality and complexity of computer games have advanced significantly. Computer graphics have shown the most noticeable improvement, with the number of polygons rendered in a scene increasing almost exponentially each year, significantly enhancing the games' realism. For example, the original Playstation, released in 1995, renders 300,000 polygons per second, while Sega's Dreamcast, released in 1999, renders 3 million polygons per second. The Playstation 2 sets the current standard, rendering 66 million polygons per second, while projections indicate the Xbox will render more than lOO million polygons per second. Thus, the images on today's $300 game consoles rival or surpass those available on the previous decade's $50,000 computers. The impact of these improvements is evident in the complexity and realism of the environments underlying today's games, from detailed indoor rooms and corridors to vast outdoor landscapes. These games populate the environments with both human and computer controlled characters, making them a rich laboratory for artificial intelligence research into developing intelligent and social autonomous agents. Indeed, computer games offer a fitting subject for serious academic study, undergraduate education, and graduate student and faculty research. Creating and efficiently rendering these environments touches on every topic in a computer science curriculum. The "Teaching Game Design " sidebar describes the benefits and challenges of developing computer game design courses, an increasingly popular field of study

title	Generative Polymodal Music Process
source	International Conference on Generative Art
summary	We present underlying ideas used to develop an Algorithmic Composition software named KYKLOS. It was designed to generate music based on generalised musical scales and modes. It is an interactive sonic device to be applied in composition as well in performance. The sonic output of the whole process can be described as generalised polymodal music since “synthetic scales” are generated by the algorithm. This environment can be used in a Computer Assisted Composition manner in order to generate MIDI files. On the other hand, it can equally be used as a performance environment in which a dynamic change of parameters enables a real time control of the sonic process. Recently, we advocated that several mathematical applications in Computer Music can be understood as Sound Functors [1]. In extension, we describe here a sound functor used to model scales and modes. As can be verified, part of early investigations on mathematical structures in music studied musical scales and modes using Combinatorics, Fibonacci Series and Golden Mean in order to understand compositional processes which use modal concepts. Using the Functor definition it is possible to enumerate n-scales as a sequence of integers. Each value in that sequence gives the distance (in half tones) between two consecutive tones. For example, the sequence 3:2:2:3 is interpreted as a pentatonic scale C-Eb-F-G-Bb, and as defined above it is a C mode. So, if we apply cyclical permutations, (n-1)-sequences of numbers should be interpreted as n-modes of tones. Our algorithmic implementation is described briefly. A n-mode is defined as an array with n-1 integers [a1, a2, ...an-1]. Each array generated at k-th step can be read as a number a1a2a3 ....an-1 in decimal representation, where ai is a integer between 1 and 9. We denote the number obtained at k-th step as (a1a2a3 ...an-1)(k) . The rules to implement the algorithm are the following:1) V0 = (1, 1, 1, 1 ......,1) (initial n-mode)2) ? ai ? 11 with i= 1, 2...n-1 (octave range constraint)3) Vk = (a1a2a3 ...an-1)(k) < (b1b2b3 ...bn-1)(k+1) = Vk+1 where aj ?bj , 1? j ? n-1.4) Vmax = (13 – n, 1, 1, ...,1)In this paper we start with a theoretical view and an introduction on the algorithmic mechanism used. Further, we present a concept of man ? machine interaction used to create the composition environment. We also describe the compositional graphic interface developed and general functions of the system. Finally there is a set of music examples generated by KYKLOS as MIDI files.
