title	Ready-to-Run Java 3D
source	Wiley Computer Publishing
summary	Written for the intermediate Java programmer and Web site designer, Ready-to-Run Java 3D provides sample Java applets and code using Sun's new Java 3D API. This book provides a worthy jump-start for Java 3D that goes well beyond the documentation provided by Sun. Coverage includes downloading the Java 2 plug-in (needed by Java 3D) and basic Java 3D classes for storing shapes, matrices, and scenes. A listing of all Java 3D classes shows off its considerable richness. Generally, this book tries to cover basic 3D concepts and how they are implemented in Java 3D. (It assumes a certain knowledge of math, particularly with matrices, which are a staple of 3D graphics). Well-commented source code is printed throughout (though there is little additional commentary). An applet for orbiting planets provides an entertaining demonstration of transforming objects onscreen. You'll learn to add processing for fog effects and texture mapping and get material on 3D sound effects and several public domain tools for working with 3D artwork (including converting VRML [Virtual Reality Markup Language] files for use with Java 3D). In all, this book largely succeeds at being accessible for HTML designers while being useful to Java programmers. With Java 3D, Sun is betting that 3D graphics shouldn't require a degree in computer science. This book reflects that philosophy, though advanced Java developers will probably want more detail on this exciting new graphics package. --Richard Dragan Topics covered: Individual applets for morphing, translation, rotation, and scaling; support for light and transparency; adding motion and interaction to 3D objects (with Java 3D classes for behaviors and interpolators); and Java 3D classes used for event handling.

title	Utilización de un programa didáctico para la formación de desarrolladores, arquitectos, ingenieros y diseñadores (Use of a Didactic Program for the Training of Developers, Architects, Engineers and Designers)
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 352-356
summary	For those questions of the specialisation, the Informaitc engineers develop applications of digital graphic destined to designers, users that, in general, ignore with the chore of developing applications. Also, most of the designers have to fight with applications that do not contemplate their necessities neither translates their expressive intentions with clarity. This reciprocal discussion may find an adequate solution in interdisciplinary work. The fecundity, and until the possibility, of the internal dialogue of these teams will depend, between other looks, of the quantity of common concepts that they possess. In this sense, we focused our educational task opposite the future engineers. We understand that, at the same time, the actual education of the designer, in whatever of their multiple looks, should contemplate the basic training (not instrumental but if conceptual) in questions related with the code of the applications that they use. This intellectual effort would enable the digital designer to investigate the topics of personalising their user applications (AutoCAD, CorelDraw, etc.). In this ground, we should greet the admission of the languages of visual code (Delphi, Visual [basic], etc.) that they permit a friendlier development of applications. Its goal is qualify them in order to develop applications of digital graphic, providing them concepts of space understanding and visual training for the production of IT applications of digital graphic.

title	Internet-based collaborative design evaluation : an architect's perspective
source	Harvard University
summary	This research aims at developing a design evaluation system that employs a Product Model as the logical basis for integrating building design and construction processes. The system is implemented with Java language, which allows the system to work over the Internet. Accordingly, the system helps architects to collaborate with remote participants. Thus, this design evaluation system is a building performance evaluator like DOE-2, RADIANCE, HVAC, and the Automated Building Code Checker. This research, however, is mainly concerned with an architect's view during the schematic design and design development stage, while the existing design evaluation systems cover other special consultants' views such as those of HVAC designers, structural engineers, and contractors. From an architect's view, this evaluation system checks the compliance of design objects represented by means of physical objects such as walls and windows and conceptual objects such as rooms as well, to the design criteria focused on accommodating human behavior, rather than other building performances such as sustaining building structures and maintaining indoor livability. As such, the system helps designers analyze and evaluate design solutions according to their original intent. The innovative points of this research lie in the following: (1) Unlike other inquiries, it addresses a systematic evaluation of building design from an architect's view focusing on the experiential quality of the built environment. This research demonstrates that such an evaluation becomes available by introducing human activity-based evaluation. (2) It can take a multi-agenda for several groups of different interests by providing an Aspect Model based on human activity-centered systematic translation of their design considerations and 3D model-based graphical representations into system readable ones. (3) As a result, it addresses the possibility of expanding the capability of the design evaluator from a mere code checker to a general design evaluator while simultaneously, enhancing the availability from stand alone to Internet based networking.

title	How I Drew One of My Pictures: * or, The Authorship of Generative Art
source	International Conference on Generative Art
summary	The concept of value is traditionally bestowed on a work of art when it is seen to be unique and irreproducible, thereby granting it authenticity. Think of a famous painting: only the original canvas commands genuinely high prices. Digital artwork is not valued in the same way. It can be copied infinitely and there is therefore a corresponding crisis of value. It has been argued that under these conditions of the dematerialised artwork, it is process that becomes valued. In this way, the process of creation and creativity is valued in place of authenticity, undermining conventional notions of authorship. It is possible to correlate many of these creative processes into instructions. However, to give precise instructions on the construction of a creative work is a complex, authentic and intricate process equivalent to conventional creative work (and is therefore not simply a question of 'the death of the author'). This paper argues that to create ‘generative’ systems is a rigorous and intricate procedure. Moreover, the output from generative systems should not be valued simply as an endless, infinite series of resources but as a system. To have a machine write poetry for ten years would not generate creative music, but the process of getting the machine to do so would certainly register an advanced form of creativity. When a programmer develops a generative system, they are engaged in a creative act. Programming is no less an artform than painting is a technical process. By analogy, the mathematical value pi can be approximated as 3.14159265, but a more thorough and accurate version can be stored as the formula used to calculate it. In the same way, it is more complete to express creativity formulated as code, which can then be executed to produce the results we desire. Rather like using Leibnitz's set of symbols to represent a mathematical formula, artists can now choose to represent creativity as computer programs (Harold Cohen’s Aaron, a computer program that creates drawings is a case in point). By programming computers to undertake creative instructions, this paper will argue that more accurate and expansive traces of creativity are being developed that suitably merge artistic subjectivity with technical form. It is no longer necessary or even desirable to be able to render art as a final tangible medium, but instead it is more important to program computers to be creative by proxy.

title	Envisioning Cyberspace: Designing 3D Electronic Spaces
source	McGraw-Hill, NY
summary	Free of the constraints of physical form and limited only by imagination, new environments spring to life daily in a fantastic realm called cyberspace. The creators of this new virtual world may be programmers, designers, architects, even children. In this invigorating exploration of the juncture between cyberspace and the physical world, architect Peter Anders brings together leading-edge cyberspace art and architecture ... inspiring new techniques and technologies ... unexpected unions of reality and virtuality ... and visions of challenges and opportunities as yet unexplored. More than an invitation to tour fantastic realms and examine powerful tools, this book is a hard-eyed look at cyberspace's impact on physical, cultural, and social reality, and the human-centered principles of its design. This is a book that will set designers and architects thinkingNand a work of importance to anyone fascinated with the fast-closing space between the real and the virtual.

title	Let's Improvise Together
source	International Conference on Generative Art
summary	The creators of ‘Let's-Improvise-Together’ adhere to the idea that while there is a multitude of online games now available in cyberspace, it appears that relatively few are focused on providing a positive, friendly and productive experience for the user. Producing this kind of experience is one the goals of our Amusement Project.To this end, the creation of ‘Let's Improvise Together’ has been guided by dedication to the importance of three themes:* the importance of cooperation,* the importance of creativity, and* the importance of emotion.Description of the GameThe avatar arrives in a certain area where there are many sound-blocks/objects. Or he may add sound "property" to existing ones. He can add new objects at will. Each object may represents a different sound, they do not have to though. The avatar walks around and chooses which objects he likes. Makes copies of these and add sounds or change the sounds on existing ones, then with all of the sound-blocks combined make his personalized "instrument". Now any player can make sounds on the instrument by approaching or bumping into a sound-block. The way that the avatar makes sounds on the instrument can vary. At the end of the improvising session, the ‘composition’ will be saved on the instrument site, along with the personalized instrument. In this way, each user of the Amusement Center will leave behind him a unique instrumental creation, that others who visit the Center later will be able to play on and listen to. The fully creative experience of making a new instrument can be obtained connecting to Active Worlds world ‘Amuse’ and ‘Amuse2’.Animated colorful sounding objects can be assembled by the user in the Virtual Environment as a sort of sounding instrument. We refrain here deliberately from using the word musical instrument, because the level of control we have on the sound in terms of rythm and melody, among other parameters, is very limited. It resembles instead, very closely, to the primitive instruments used by humans in some civilizations or to the experience made by children making sound out of ordinary objects. The dimension of cooperation is of paramount importance in the process of building and using the virtual sounding instrument. The instrument can be built on ones own effort but preferably by a team of cooperating users. The cooperation has as an important corolary: the sharing of the experience. The shared experience finds its permanence in the collective memory of the sounding instruments built. The sounding instrument can be seen also as a virtual sculpture, indeed this sculpture is a multimedial one. The objects have properties that ranges from video animation to sound to virtual physical properties like solidity. The role of the user representation in the Virtual World, called avatar, is important because it conveys, among other things, the user’s emotions. It is worth pointing out that the Avatar has no emotions on its own but it simply expresses the emotions of the user behind it. In a way it could be considered a sort of actor performing the script that the user gives it in real-time while playing.The other important element of the integration is related to the memory of the experience left by the user into the Virtual World. The new layout is explored and experienced. The layout is a permanent editable memory. The generative aspects of Let's improvise together are the following.The multi-media virtual sculpture left behind any participating avatar is not the creation of a single author/artist. The outcome of the sinergic interaction of various authors is not deterministic, nor predictable. The authors can indeed use generative algorythm in order to create the texture to be used on the objects. Usually, in our experience, the visitors of the Amuse worlds use shareware programs in order to generate their texture. In most cases the shareware programs are simple fractals generators. In principle, it is possible to generate also the shape of the object in a generative way. Taking into account the usual audience of our world, we expected visitors to use very simple algorythm that could generate shapes as .rwx files. Indeed, noone has attempted to do so insofar. As far as the music is concerned, the availability of shareware programs that allow simple generation of sounds sequences has made possible, for some users, to generate sounds sequences to be put in our world. In conclusion, the Let's improvise section of the Amuse worlds could be open for experimentation on generative art as a very simple entry point platform. We will be very happy to help anybody that for educational purposes would try to use our platform in order to create and exhibit generative forms of art.

title	Understanding Hypermedia
source	Phaidon Press Ltd, London
summary	Understanding Hypermedia 2,000 is a wonderful read. It takes you on a journey tracing the origins of hypermedia from its very early beginings way back in the 1700's with the birth of print, all the way through to the modern new media revolution. It charts the developments in technology, culture, science and the arts to give you a very broad understanding of just what hypermedia is and where it came from. Looking to the future, Understanding Hypermedia looks at the components of hypermedia - interface design, typography, text, animation, video, vrml, etc -, the processes of designing and building new media projects - including examples from the web, cdrom and kiosks - and the future of the medium. From the hypermedia innovators to the visionaries of cyberspace. This book is a wonderful, rich and fasinating source of information and inspiration for anyone interested in or working with new media today.

title	Technoromanticism - digital narrative, holism, and the romance of the real
source	MIT Press
summary	It's no secret that contemporary culture romanticizes digital technologies. In books, articles, and movies about virtual community, virtual reality, artificial intelligence, artificial life, and other wonders of the digital age, breathless anticipation of vast and thrilling changes has become a running theme. But as Richard Coyne makes clear in Technoromanticism: Digital Narrative, Holism, and the Romance of the Real, a dense but rewarding piece of academic criticism, we also get romantic about the new technologies in a more rigorous sense of the word. Whether heralding an electronic return to village communalism or celebrating cyberspace as a realm of pure mind, today's utopian thinking about the digital, Coyne argues, essentially replays the 18th- and 19th-century cultural movement called Romanticism, with its powerful yearnings for transcendence and wholeness. And this apparently is not a good thing. Romanticism, like the more sober Enlightenment rationalism against which it rebelled, has outlived its usefulness as a way of understanding the world, Coyne argues. And so he spends the duration of the book bombarding both the romantic and the rationalist tendencies in cyberculture with every weapon in the arsenal of 20th-century critical theory: poststructuralism, Freudianism, postmodern pragmatism, Heideggerian phenomenology, surrealism--Coyne uses each in turn to whack away at conventional wisdoms about digital tech. Whether the conventional wisdoms remain standing at the end is an open question, but Coyne's tour of the contemporary intellectual landscape is a tour de force, and never before has digital technology's place in that landscape been mapped so thoroughly. --

summary	This project investigates in the limits of the word like only means of structuring of the thought, before the appearance of new paradigms: the multimedias and the ciber-space that have transformed so much the language written as the architectural one causing unpublished situations: 1.) The transformation of a concrete container to other virtual. 2.) The transformation of the design object, of one static material to another that is a process. 3.) The transformation in the traditional ways of thinking (reversible as the formal logic of the mathematics) to new imaginarys epistemologicals. // These non alone events have caused changes in the forms of to know and to communicate the reality but rather the same one suffers a dilation process. We present for their exploration, a road synthesized in some hypotheses that were elaborated with reason of the International Competition of ACADIA 1998: 1.) The new communication systems (cibercomunication) they generate a new territory that should be colonized. This territory this conformed by objects related by infinite bonds (hipertext). 2.) The topographical form is not lineal and sequential, this it is multidirectional and multiradial. The phenomenon of the blow-up and the dilation are the mechanisms with those that the new objects are generated. 3.) These related fields generate interstitial empty spaces where it appears the desire. The interstice like existential space.

title	Geographic Information Database for Landscape Evaluation

summary	In a landscape evaluation of a large-scale facilities construction such as garbage disposal facilities, it is necessary to grasp landscape characteristics of the area that is able to observe object facilities. This landscape characteristic consists of both a geographical characteristic (landscape resources, public space, districts designated by various urban planing laws, etc.) and a visual characteristic (visibility / invisibility range, distance from the object). The facilities design with consideration for landscape requires a geographic information database for the landscape characteristic, which enable planners to share the geographic information in the area. Authors proposed Network-based Dynamic Evaluation Process for urban landscapes in CAADRIA98, and illustrated the need of the common place that shares geographic information in the process. The system has function to provide the information of the area with layered maps simply. However the system developed with HTML Layer Function, that has limited to update data and boolean operate of layers. For using the system for practical purposes, it should conduct a GIS lookup and report back, via HTML. On the other hand, at present, there are various analogue thematic maps, digital maps are not prepared enough for landscape evaluation. It causes that landscape design process is not efficient. Also, a potential (importance) of viewpoints for evaluating facilities design have been defined by qualitative analysis so far, therefore a quantitative comparison of viewpoints was not available. As a solution of those problems, authors are tackling the development of Geographic Information Database (GIDB) by using GIS. In this paper authors give an outline of GIDB composed of overlaying various digital thematic maps included visual characteristic of the facilities. As a case study, in construction of the garbage disposal facilities in Kumamoto city, the important viewpoints was extracted by GIDB.

source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 379-383
summary	One of the most interesting areas in the forefront of non-immersive virtual reality (VRML) applications to architecture is the one that concerns the design, construction and exploration of on-line multi-access worlds using the Internet-WWW. However, and despite the great proliferation of earlier single-access models built on VRML, attempts to collect, classify and provide accesibility that type of models has proved almost nil. On the other side, one of the architectural typologies that promises the greatest transformation potential in the virtual architecture area in cyberspace is the one that concerns virtual museums and galleries. This paper seeks to provide a bridge between the two aforementioned approaches by formulating a conceptual basis for the creation of a virtual, on-line, multi-access museum intended to house collections of VRML building models. Such models, initially shown at a conventional model scale, would be accessed by visitors through an interface intended to transport those visitors into the models’ environments, where changes in scale could provide navigation access to interior and exterior view of the building . Accordingly, the museum would act as a sort of "spaceport” toward different routes of exploration. This modelistic cascading seems to offer interesting possibilities as regards future virtual architecture applications.

title	The Pearly Gates of Cyberspace: A History of Space from Dante to the Internet
source	Doubleday, Sydney
summary	Ever since the online world began, its inhabitants have puzzled over a fundamental question: What sort of space, exactly, is cyberspace? Is it just a metaphor, a vivid shorthand for the abstract complexity of computer networks? Or is it in some sense actually a space that parallels the one our bodies live in? Wertheim's impressively argued answer in The Pearly Gates of Cyberspace: A History of Space from Dante to the Internet is that it is both, and more. Cyberspace, she claims, at once exposes and fulfills a long-time cultural yearning for the type of immaterial space, the realm of the soul, that was written out of the West's cosmological picture when science displaced medieval theology.

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.

summary	"Space," which has long been an important concept in architecture (Bloomer & Moore, 1977; Mitchell, 1995, 1999), has attracted interest of researchers from various academic disciplines in recent years (Agnew, 1993; Benko & Strohmayer, 1996; Chang, 1999; Foucault, 1982; Gould, 1998). Researchers from disciplines such as anthropology, geography, sociology, philosophy, and linguistics regard it as the basis of the discussion of various theories in social sciences and humanities (Chen, 1999). On the other hand, since the invention of Internet, Internet users have been experiencing a new and magic "world." According to the definitions in traditional architecture theories, "space" is generated whenever people define a finite void by some physical elements (Zevi, 1985). However, although Internet is a virtual, immense, invisible and intangible world, navigating in it, we can still sense the very presence of ourselves and others in a wonderland. This sense could be testified by our naming of Internet as Cyberspace -- an exotic kind of space. Therefore, as people nowadays rely more and more on the Internet in their daily life, and as more and more architectural scholars and designers begin to invest their efforts in the design of virtual places online (e.g., Maher, 1999; Li & Maher, 2000), we cannot help but ask whether there are indeed sensible spaces in Internet. And if yes, these spaces exist in terms of what forms and created by what ways?To join the current interdisciplinary discussion on the issue of space, and to obtain new definition as well as insightful understanding of "space", this study explores the spatial phenomena in Internet. We hope that our findings would ultimately be also useful for contemporary architectural designers and scholars in their designs in the real world.As a preliminary exploration, the main objective of this study is to discover the elements involved in the creation/construction of Internet spaces and to examine the relationship between human participants and Internet spaces. In addition, this study also attempts to investigate whether participants from different academic disciplines define or experience Internet spaces in different ways, and to find what spatial elements of Internet they emphasize the most.In order to achieve a more comprehensive understanding of the spatial phenomena in Internet and to overcome the subjectivity of the members of the research team, the research design of this study was divided into two stages. At the first stage, we conducted literature review to study existing theories of space (which are based on observations and investigations of the physical world). At the second stage of this study, we recruited 8 Internet regular users to approach this topic from different point of views, and to see whether people with different academic training would define and experience Internet spaces differently.The results of this study reveal that the relationship between human participants and Internet spaces is different from that between human participants and physical spaces. In the physical world, physical elements of space must be established first; it then begins to be regarded as a place after interaction between/among human participants or interaction between human participants and the physical environment. In contrast, in Internet, a sense of place is first created through human interactions (or activities), Internet participants then begin to sense the existence of a space. Therefore, it seems that, among the many spatial elements of Internet we found, "interaction/reciprocity" Ñ either between/among human participants or between human participants and the computer interface Ð seems to be the most crucial element.In addition, another interesting result of this study is that verbal (linguistic) elements could provoke a sense of space in a degree higher than 2D visual representation and no less than 3D visual simulations. Nevertheless, verbal and 3D visual elements seem to work in different ways in terms of cognitive behaviors: Verbal elements provoke visual imagery and other sensory perceptions by "imagining" and then excite personal experiences of space; visual elements, on the other hand, provoke and excite visual experiences of space directly by "mapping".Finally, it was found that participants with different academic training did experience and define space differently. For example, when experiencing and analyzing Internet spaces, architecture designers, the creators of the physical world, emphasize the design of circulation and orientation, while participants with linguistics training focus more on subtle language usage. Visual designers tend to analyze the graphical elements of virtual spaces based on traditional painting theories; industrial designers, on the other hand, tend to treat these spaces as industrial products, emphasizing concept of user-center and the control of the computer interface.The findings of this study seem to add new information to our understanding of virtual space. It would be interesting for future studies to investigate how this information influences architectural designers in their real-world practices in this digital age. In addition, to obtain a fuller picture of Internet space, further research is needed to study the same issue by examining more Internet participants who have no formal linguistics and graphical training.

This move is made possible by progress in fire safety technologies, including the development of engineering tools that are required to implement performance codes. The development of performance-based codes follows a transparent, hierarchical structure in which there are usually three levels of objectives. The top level objectives usually state the functional requirements and the lowest level the performance criteria. Usually, one middle level exists, however, more levels can be used in this hierarchical structure depending on the complexity of the requirements. The success of performance-based codes depends on the ability to establish performance criteria that will be verifiable and enforceable. The performance criteria should be such that designers can easily demonstrate, using engineering tools, that their designs meet them and that the code authority can enforce them. This paper presents the performance criteria that are currently used by fire protection engineers in designing fire safety systems in buildings. These include deterministic and probabilistic design criteria as well as safety factors. The deterministic criteria relate mainly to life safety levels, fire growth and spread levels, fire exposure and structural performance. The probabilistic criteria focus on the incident severity and incident likelihood. Finally, the inclusion of safety factors permits a conservative design and allows for a smaller margin of error due to uncertainty in the models and the input data.

summary	The VR-DIS research programme aims at the development of a Virtual Reality – Design Information System. This is a design and decision support system for collaborative design that provides a VR interface for the interaction with both the geometric representation of a design and the non-geometric information concerning the design throughout the design process. The major part of the research programme focuses on early stages of design. The programme is carried out by a large number of researchers from a variety of disciplines in the domain of construction and architecture, including architectural design, building physics, structural design, construction management, etc.Management of design information is at the core of this design and decision support system. Much effort in the development of the system has been and still is dedicated to the underlying theory for information management and its implementation in an Application Programming Interface (API) that the various modules of the system use. The theory is based on a so-called Feature-based modelling approach and is described in the PhD thesis by [first author, 1999] and in [first author et al., 2000a]. This information modelling approach provides three major capabilities: (1) it allows for extensibility of conceptual schemas, which is used to enable a designer to define new typologies to model with; (2) it supports sharing of conceptual schemas, called type-libraries; and (3) it provides a high level of flexibility that offers the designer the opportunity to easily reuse design information and to model information constructs that are not foreseen in any existing typologies. The latter aspect involves the capability to expand information entities in a model with relationships and properties that are not typologically defined but applicable to a particular design situation only; this helps the designer to represent the actual design concepts more accurately.The functional design of the information modelling system is based on a three-layered framework. In the bottom layer, the actual design data is stored in so-called Feature Instances. The middle layer defines the typologies of these instances in so-called Feature Types. The top layer is called the meta-layer because it provides the class definitions for both the Types layer and the Instances layer; both Feature Types and Feature Instances are objects of the classes defined in the top layer. This top layer ensures that types can be defined on the fly and that instances can be created from these types, as well as expanded with non-typological properties and relationships while still conforming to the information structures laid out in the meta-layer.The VR-DIS system consists of a growing number of modules for different kinds of functionality in relation with the design task. These modules access the design information through the API that implements the meta-layer of the framework. This API has previously been implemented using an Object-Oriented Database (OODB), but this implementation had a number of disadvantages. The dependency of the OODB, a commercial software library, was considered the most problematic. Not only are licenses of the OODB library rather expensive, also the fact that this library is not common technology that can easily be shared among a wide range of applications, including existing applications, reduces its suitability for a system with the aforementioned specifications. In addition, the OODB approach required a relatively large effort to implement the desired functionality. It lacked adequate support to generate unique identifications for worldwide information sources that were understandable for human interpretation. This strongly limited the capabilities of the system to share conceptual schemas.The approach that is currently being implemented for the core of the VR-DIS system is based on eXtensible Markup Language (XML). Rather than implementing the meta-layer of the framework into classes of Feature Types and Feature Instances, this level of meta-definitions is provided in a document type definition (DTD). The DTD is complemented with a set of rules that are implemented into a parser API, based on the Document Object Model (DOM). The advantages of the XML approach for the modelling framework are immediate. Type-libraries distributed through Internet are now supported through the mechanisms of namespaces and XLink. The implementation of the API is no longer dependent of a particular database system. This provides much more flexibility in the implementation of the various modules of the VR-DIS system. Being based on the (supposed to become) standard of XML the implementation is much more versatile in its future usage, specifically in a distributed, Internet-based environment.These immediate advantages of the XML approach opened the door to a wide range of applications that are and will be developed on top of the VR-DIS core. Examples of these are the VR-based 3D sketching module [VR-DIS ref., 2000]; the VR-based information-modelling tool that allows the management and manipulation of information models for design in a VR environment [VR-DIS ref., 2000]; and a design-knowledge capturing module that is now under development [first author et al., 2000a and 2000b]. The latter module aims to assist the designer in the recognition and utilisation of existing and new typologies in a design situation. The replacement of the OODB implementation of the API by the XML implementation enables these modules to use distributed Feature databases through Internet, without many changes to their own code, and without the loss of the flexibility and extensibility of conceptual schemas that are implemented as part of the API. Research in the near future will result in Internet-based applications that support designers in the utilisation of distributed libraries of product-information, design-knowledge, case-bases, etc.The paper roughly follows the outline of the abstract, starting with an introduction to the VR-DIS project, its objectives, and the developed theory of the Feature-modelling framework that forms the core of it. It briefly discusses the necessity of schema evolution, flexibility and extensibility of conceptual schemas, and how these capabilities have been addressed in the framework. The major part of the paper describes how the previously mentioned aspects of the framework are implemented in the XML-based approach, providing details on the so-called meta-layer, its definition in the DTD, and the parser rules that complement it. The impact of the XML approach on the functionality of the VR-DIS modules and the system as a whole is demonstrated by a discussion of these modules and scenarios of their usage for design tasks. The paper is concluded with an overview of future work on the sharing of Internet-based design information and design knowledge.

title	Constraints in object-oriented graphics
source	Eindhoven University of Technology
summary	In the area of interactive computer graphics, two important approaches to deal with the complexity of designing and implementing graphics systems are object-oriented programming and constraint-based programming. From literature, it appears that combination of these two has clear advantages but has also proven to be difficult. One of the main problems is that constraint programming infringes the information hiding principle of object-oriented programming. The goal of the research project is to combine these two approaches to benefit from the strengths of both. Two research groups at the Eindhoven University of Technology investigate the use of constraints on graphics objects. At the Architecture department, constraints are applied in a virtual reality design environment. At the Computer Science department, constraints aid in modeling 3D animations. For these two groups, a constraint system for 3D graphical objects was developed. A conceptual model, called CODE (Constraints on Objects via Data flows and Events), is presented that enables integration of constraints and objects by separating the object world from the constraint world. In the design of this model, the main aspect being considered is that the information hiding principle among objects may not be violated. Constraint solvers, however, should have direct access to an object’s internal data structure. Communication between the two worlds is done via a protocol orthogonal to the message passing mechanism of objects, namely, via events and data flows. This protocol ensures that the information hiding principle at the object-oriented programming level is not violated while constraints can directly access “hidden” data. Furthermore, CODE is built up of distinct elements, or entity types, like constraint, solver, event, data flow. This structure enables that several special purpose constraint solvers can be defined and made to cooperate to solve complex constraint problems. A prototype implementation was built to study the feasibility of CODE. Therefore, the implementation should correspond directly to the conceptual model. To this end, every entity (object, constraint, solver) of the conceptual model is represented by a separate process in the language MANIFOLD. The (concurrent) processes communicate by events and data flows. The implementation serves to validate the conceptual model and to demonstrate that it is a viable way of combining constraints and objects. After the feasibility study, the prototype was discarded. The gained experience was used to build an implementation of the conceptual model for the two research groups. This implementation encompassed a constraint system with multiple solvers and constraint types. The constraint system was built as an object-oriented library that can be linked to the applications in the respective research groups. Special constructs were designed to ensure information hiding among application objects while constraints and solvers have direct access to the object data. CODE manages the complexity of object-oriented constraint solving by defining a communication protocol to allow the two paradigms to cooperate. The prototype implementation demonstrates that CODE can be implemented into a working system. Finally, the implementation of an actual application shows that the model is suitable for the development of object-oriented software.
