title	The Anatomy of a Large-Scale Hypertextual Web Search Engine
source	Computer Science Department, Stanford University, Stanford, CA
summary	In this paper, we present Google, a prototype of a large-scale search engine which makes heavy use of the structure present in hypertext. Google is designed to crawl and index the Web efficiently and produce much more satisfying search results than existing systems. The prototype with a full text and hyperlink database of at least 24 million pages is available at http://google.stanford.edu/ To engineer a search engine is a challenging task. Search engines index tens to hundreds of millions of web pages involving a comparable number of distinct terms. They answer tens of millions of queries every day. Despite the importance of large-scale search engines on the web, very little academic research has been done on them. Furthermore, due to rapid advance in technology and web proliferation, creating a web search engine today is very different from three years ago. This paper provides an in-depth description of our large-scale web search engine -- the first such detailed public description we know of to date. Apart from the problems of scaling traditional search techniques to data of this magnitude, there are new technical challenges involved with using the additional information present in hypertext to produce better search results. This paper addresses this question of how to build a practical large-scale system which can exploit the additional information present in hypertext. Also we look at the problem of how to effectively deal with uncontrolled hypertext collections where anyone can publish anything they want.

title	VRML In Architectural Construction Documents: A Case Study
source	VRML 98 Monterey - Proceedings of the 1998 VRML Conference, pp. 115-120
summary	The Virtual Reality Modeling Language (VRML) and the World Wide Web (WWW) offer new opportunities to communicate an architect's design intent throughout the design process. We have investigated the use of VRML in the production and communication of construction documents, the final phase of architectural building design. A prototype, experimental Web site was set up and used to disseminate design data as VRML models and HTML text to the design client, contractor, and fabricators. In this paper, we discuss the way our construction documents were developed in VRML, the issues we faced implementing it, and critical feedback from the users of the Web space/site. Finally, we suggest ways to enhance the VRML specification which would enable its widespread use as a communication tool in the design and construction industries.

summary	The remarkable advances in the technology of computer systems, including software, hardware, and networks, continuously give us new avenues to be utilized in education. The pedagogic strategy to be developed in the utilization of digital graphic systems applied to three-dimensional design in architecture (both in the design and virtual expression of objects or already designed architectural groups) is still changing with the times.Therefore, the Department, as an extension of its experience with this type of development and as a response to deal with special situations such as large numbers of students, develops this new proposal, which is currently being used. This project uses the implementation, structuring, and building of a virtual site as an informatics classroom, utilizing multimedia systems, to be used as a support for acquiring knowledge during the learning that takes place doing the coursework. This setting would allow for the feedback between the instructor and the student to be on-going, hence both groups being efficiently motivated through examples and opportunities of how to do the following: utilize appropriate technology, manipulate the right information, utilize the right kind of software programs and techniques, revamp the knowledge, and benefit from using the appropriate digital techniques for each specific case of architectural design and expression.

title	The architectural aspect of designing space in virtual environments
source	University of Strathclyde, Dept. of Architecure and Building Science
summary	This thesis deals with the architectural aspect of virtual environment design. It aims at proposing a framework, which could inform the design of three-dimensional content for defining space in virtual environments, in order to aid navigation and wayfinding. The use of such a framework in the design of certain virtual environments is considered necessary for imposing a certain form and structure to our spatial experience in there. Firstly, this thesis looks into literature from the fields of architectural and urban design theory, philosophy, environmental cognition, perceptual psychology and geography for the purpose of identifying a taxonomy of spatial elements and their structure in the real world, on the basis of the way that humans think about and remember real environments. Consequently, the taxonomy, proposed for space in the real world is adapted to the intrinsic characteristics of space in virtual environments, on the basis of human factors aspects of virtual reality technology. As a result, the thesis proposes a hypothetical framework consisting of a taxonomy of spatial and space-establishing elements that a virtual environment may comprise and of the possible structure of these elements. Following this framework, several pilot virtual environments are designed, for the purpose of identifying key design issues for evaluation. As it was impossible to evaluate the whole framework, six specific design issues, which have important implications for the design of space in virtual environments, are investigated by experimental methods of research. Apart from providing answers to these specific design issues, the experimental phase leads to a better understanding of the nature of space in virtual environments and to several hypotheses for future empirical research.

title	From Inversive Perspective to Virtual Space
source	Cyber-Real Design [Conference Proceedings / ISBN 83-905377-2-9] Bialystock (Poland), 23-25 April 1998, pp. 43-52
summary	Looking back at history, considering the proportions taken up by the particular developments of the future vision of an architectural work, one observes that the main method used was based on a form of drawing in the perpendicular projection in the form of "planes", cross sections and elevations. However, the research considering the threedimensional approach of the design solution, took into consideration a model made of wood, plaster or paper. The supplementary works in the form of an axonometric or a perspective drawing were not usually the domain of architects. Such way of presenting space was used by artists: painters and sculptors. The rapid development taking place in the use of computers in preparing architectural design documentation makes one reflect on many issues. Modern software, apart from making it possible to develop projections, cross sections and elevations, allows the presentation of a three dimensional vision of an architectural solution on the basis of axonometry, perspective and a study of virtual space. Despite the obvious progress facilitating the graphic editing process of design work, the initial design phase is an unchanged process, similar to past times ' It is based on transferring the creative invention onto paper by means of handmade sketches, similarly to making an inventory measurement note.

title	The use of genetic programming for applications in the field of spatial composition
source	International Conference on Generative Art
summary	Architectural design teaching using computers has been a preoccupation of CECA since 1991. All design tutors provide their students with a set of models and ways to form, and we have explored a set of approaches including cellular automata, genetic programming ,agent based modelling and shape grammars as additional tools with which to explore architectural ( and architectonic) ideas.This paper discusses the use of genetic programming (G.P.) for applications in the field of spatial composition. CECA has been developing the use of Genetic Programming for some time ( see references ) and has covered the evolution of L-Systems production rules( coates 1997, 1999b), and the evolution of generative grammars of form (Coates 1998 1999a). The G.P. was used to generate three-dimensional spatial forms from a set of geometrical structures .The approach uses genetic programming with a Genetic Library (G.Lib) .G.P. provides a way to genetically breed a computer program to solve a problem.G. Lib. enables genetic programming to define potentially useful subroutines dynamically during a run .* Exploring a shape grammar consisting of simple solid primitives and transformations. * Applying a simple fitness function to the solid breeding G.P.* Exploring a shape grammar of composite surface objects. * Developing grammarsfor existing buildings, and creating hybrids. * Exploring the shape grammar of abuilding within a G.P.We will report on new work using a range of different morphologies ( boolean operations, surface operations and grammars of style ) and describe the use of objective functions ( natural selection) and the "eyeball test" ( artificial selection) as ways of controlling and exploring the design spaces thus defined.

title	Rendering synthetic objects into real scenes: Bridging traditional and image-based graphics with global illumination and high dynamic range photography
source	Proc. ACM SIGGRAPH 98, M. Cohen, Ed., 189–198
summary	We present a method that uses measured scene radiance and global illumination in order to add new objects to light-based models with correct lighting. The method uses a high dynamic range imagebased model of the scene, rather than synthetic light sources, to illuminate the newobjects. To compute the illumination, the scene is considered as three components: the distant scene, the local scene, and the synthetic objects. The distant scene is assumed to be photometrically unaffected by the objects, obviating the need for re- flectance model information. The local scene is endowed with estimated reflectance model information so that it can catch shadows and receive reflected light from the new objects. Renderings are created with a standard global illumination method by simulating the interaction of light amongst the three components. A differential rendering technique allows for good results to be obtained when only an estimate of the local scene reflectance properties is known. We apply the general method to the problem of rendering synthetic objects into real scenes. The light-based model is constructed from an approximate geometric model of the scene and by using a light probe to measure the incident illumination at the location of the synthetic objects. The global illumination solution is then composited into a photograph of the scene using the differential rendering technique. We conclude by discussing the relevance of the technique to recovering surface reflectance properties in uncontrolled lighting situations. Applications of the method include visual effects, interior design, and architectural visualization.

title	The Impact of Virtual Reality on the Design Process
source	Digital Design Studios: Do Computers Make a Difference? [ACADIA Conference Proceedings / ISBN 1-880250-07-1] Québec City (Canada) October 22-25, 1998, pp. 138-163
doi	https://doi.org/10.52842/conf.acadia.1998.138
summary	Sketching, either hand or computer generated, along with other traditional visualization tools such as perspective drawing have difficulty in correctly representing three dimensional objects. Even physical models, in architecture, suffer in this regard because of inevitable scaling. The designer finds himself cut off from the reality of the object and is prone to misinterpretations of the object and its surrounding space and to resulting design errors. These are sometimes not perceived until too late, once the object has been constructed. Traditional tools use 2D media to represent 3D objects and only manage to introduce the third dimension in a limited manner (perspectives, not only tedious to construct, are static). This scenario affects the design process, particularly the cycle of proposal, verification and correction of design hypotheses as well as the cognitive aspects that condition the designer’s visualization of the designed object. In most cases, computer graphics mimic, through its interface, the traditional way of doing things. The architectural model is parametricized with little regard for visualization. No allowance is made for the change in the medium of graphic representation. Moreover, effort is not made to capitalize on the advantages of numerical calculation to propose new interfaces and new dimensions in object visualization. Virtual Reality (VR), seen not only as technology but as experience, brings the 3D object, abstractly viewed by traditional means, into clearer focus and provides us with these new dimensions. Errors due to abstracted representation are reduced since the interface is always three dimensional and the interactions intuitively made in real time thus allowing the designer to experience the presence of the designed object very quickly. At the École de design industriel of the Faculté d’aménagement, we have run tests using non-immersive VR–one passive (comprehension) and another active (design). This project, involving a group of 72 students during a period of six weeks (6h/week), aimed at analyzing the impact of VR as a visualization tool on the design process versus traditional tools. The results, described in this presentation, shed light on the effect of VR on the creative process as such, as well as on the quality of the results produced by that process.

title	Collage, Technology, and Creative Process
source	International Conference on Generative Art
summary	Since the turn of the twentieth century artists have been using collage to suggest new realities and changing concepts of time. Appropriation and simulation can be found in the earliest recycled scraps in Cubist collages. Picasso and Braque liberated the art world with cubism, which integrated all planes and surfaces of the artists' subjects and combined them into a new, radical form. The computer is a natural extension of their work on collage. The identifying characteristics of the computer are integration, simultaneity and evolution which are inherent in collage. Further, the computer is about "converting information". There is something very facinating about scanning an object into the computer, creating a texture brush and drawing with the object's texture. It is as if the computer not only integrates information but different levels of awareness as well. In the act of converting the object from atoms to bits the object is portrayed at the same conscious level as the spiritual act of drawing. The speed and malleability of transforming an image on the computer can be compared to the speed and malleability of thought processes of the mind. David Salle said, "one of the impulses in new art is the desire to be a mutant, whether it involves artificial intelligence, gender or robotic parts. It is about the desire to get outside the self and the desire to trandscend one's place." I use the computer to transcend, to work in different levels of awareness at the same time - the spiritual and the physical. In the creative process of working with computer, many new images are generated from previous ones. An image can be processed in unlimited ways without degradation of information. There is no concept of original and copy. The computer alters the image and changes it back to its original in seconds. Each image is not a fixed object in time, but the result of dynamic aspects which are acquired from previous works and each new moment. In this way, using the computer to assist the mind in the creative processes of making art mirrors the changing concepts of time, space, and reality that have evolved as the twentieth century has progressed. Nineteenth-century concepts of the monolithic truth have been replaced with dualism and pluralism. In other words, the objective world independent of the observer, that assumes the mind is separate from the body, has been replaced with the mind and body as inseparable, connected to the objective world through our perception and awareness. Marshall Mcluhan said, "All media as extensions of ourselves serve to provide new transforming vision and awareness." The computer can bring such complexities and at the same time be very calming because it can be ultrafocused, promoting a higher level of awareness where life can be experienced more vividly. Nicholas Negroponte pointed out that "we are passing into a post information age, often having an audience of just one." By using the computer to juxtapose disparate elements, I create an impossible coherence, a hodgepodge of imagery not wholly illusory. Interestingly, what separates the elements also joins them. Clement Greenberg states that "the collage medium has played a pivotal role in twentieth century painting and sculpture"(1) Perspective, developed by the renaissance archetect Alberti, echoed the optically perceived world as reality was replaced with Cubism. Cubism brought about the destruction of the illusionist means and effects that had characterized Western painting since the fifteenth century.(2) Clement Greenberg describes the way in which physical and spiritual realities are combined in cubist collages. "By pasting a piece of newspaper lettering to the canvas one called attention to the physical reality of the work of art and made that reality the same as the art."(3) Before I discuss some of the concepts that relate collage to working with computer, I would like to define some of the theories behind them. The French word collage means pasting, or gluing. Today the concept may include all forms of composite art and processes of photomontage and assemblage. In the Foreword on Katherine Hoffman's book on Collage Kim Levin writes: "This technique - which takes bits and pieces out of context to patch them into new contexts keeps changeng, adapting to various styles and concerns. And it's perfectly apt that interpretations of collage have varied according to the intellectual inquiries of the time. From our vantage point near the end of the century we can now begin to see that collage has all along carried postmodern genes."(4) Computer, on the other hand is not another medium. It is a visual tool that may be used in the creative process. Patrick D. Prince's views are," Computer art is not concrete. There is no artifact in digital art. The images exist in the computer's memory and can be viewed on a monitor: they are pure visual information."(5) In this way it relates more to conceptual art such as performance art. Timothy Binkley explains that,"I believe we will find the concept of the computer as a medium to be more misleading than useful. Computer art will be better understood and more readily accepted by a skeptical artworld if we acknowledge how different it is from traditional tools. The computer is an extension of the mind, not of the hand or eye,and ,unlike cinema or photography, it does not simply add a new medium to the artist's repertoire, based on a new technology.(6) Conceptual art marked a watershed between the progress of modern art and the pluralism of postmodernism(7) " Once the art is comes out of the computer, it can take a variety of forms or be used with many different media. The artist does not have to write his/her own program to be creative with the computer. The work may have the thumbprint of a specific program, but the creative possibilities are up to the artist. Computer artist John Pearson feels that,"One cannot overlook the fact that no matter how technically interesting the artwork is it has to withstand analysis. Only the creative imagination of the artist, cultivated from a solid conceptual base and tempered by a sophisticsated visual sensitivity, can develop and resolve the problems of art."(8) The artist has to be even more focused and selective by using the computer in the creative process because of the multitude of options it creates and its generative qualities.

title	Data Visualization Methods for the Blind using Force Feedback and Sonification
source	Stein, M. (Ed.). Telemanipulator and Telepresence Technologies V. Vol. 3524
summary	Research in the field of scientific visualization has begun to articulate systematic methods for mapping data to a perceivable form. Most work in this area has focused on the visual sense. For blind people in particular, systematic visualization methods which utilize other sense need further development. In this work we develop methods for adding aural feedback to an existing haptic force feedback interface to create a multimodal visualization system. We examine some fundamental components of a visualization system which include the following: characterization of the data, definition of user directives and interpretation aims, cataloging of sensual representations of information, and finally, matching the data and user interpretation aims with the appropriate sensual representations. We focus on the last two components as they relate to the aural and haptic sensor. Cataloging of sensual representations is drawn form current research in sonification and haptics. The matching procedure can be thought of as a type of encoding which should be the inverse of the decoding mechanism of our aural and haptic systems. Topics in human perception are discussed, and issues related to the interaction between the two sensor are addressed. We have implemented a visualization system in the from of a Windows NT application using a sound card and a 3 DOF point interaction haptic interface. The system present a 2D data set primarily as a polygonal haptic surface although other capabilities of the haptic sensor are utilized such as texture discernment. In addition, real time aural feedback is presented as the user explores the surface. Parameters of sound such as pitch and spectral content are used to convey information. Evaluation of the system's effectiveness as an assistive technology for the blind reveals that combining aural and haptic feedback improves visualization over using either of the two senses alone.

title	Three Dimensional Object Orientation Using the Non-Dominant Hand
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The paper presents the “Turntable”, a 3D input device for orienting objects using the non-dominant hand. The device supports two-handed manipulation by allowing the non-dominant hand to orient an object while leaving the dominant hand free to perform other actions. Two-handed input is a technique that can enhance the performance, simplicity and intuitiveness of CAD systems. These properties are obligatory for CAD systems dedicated to support the conceptual phase of the design process. Anexperiment has been conducted in which the performance of the Turntable was compared to that of a well known 3D orientation method, known in literature as the “virtual sphere”. The virtual sphere is operated with the mouse using the dominant hand and is documented to be easy to use and efficient. The experiment establishes that a performance gain can be expected from a two-handed user interface that employs the Turntable for 3D object orientation with the non-dominant hand. In a single-handedinterface users must switch between rotating and manipulating an object. In a two-handed interface however, task switching is unnecessary and an additional performance benefit can be achieved when there is temporal overlap in the execution of the two tasks. Experimental results show that the Turntable, operated by the non-dominant hand, is easy to learn and its performance and accuracy are nearly equal to that of the virtual sphere operated by the dominant hand. With these results it can now be expected that a two-handed interface utilizing the Turntable performs better than a single-handed one for manipulating objects in 3D.

summary	Inkjet printing has become abundantly available to businesses, offi ces, and households ever since its commercialization in the late 1980s. Although roughly forty years have passed, the desktop printer is still limited to printing on thin fl at surfaces, mainly paper (Mills 1998). On the other hand, while larger fl atbed printing technology does offer printing on a wide-range of substrates of various thicknesses, it is limited to 2-axis printing and is mainly used for large scale commercial applications due to high machine costs. Motivated by the ambition of printing on irregular surfaces of varied mediums, improving upon high price points of existing fl at-bed printing machines, and contributing to the public knowledge of distributed manufacturing, the Direct-To-Substrate (DTS) printer is an exploration into an integrated z-axis within inkjet printing. To realign a familiar technology used by many and hack it for the purposes of expanded capabilities, the DTS allows a user to manufacture a three-dimensional artifact and later print graphics directly upon said geometry using the same machine. To remain as accessible as possible, the DTS printer is a computer-numerically-controlled desktop machine made from common, sourceable hardware parts with a tool-changeable end effector, that currently accepts a Dremel tool as a router, and a hacked inkjet cartridge

summary	The nature of the task of representing architecture alters to reflect the state of architecture at each period of time. In simulating architecture, the necessary conversion from that which is inhabitable, experiential, functional, and at times, indescribable to an abstraction in an entirely different media is often an imperfect procedure that centers on its translation rather than the actual design. The objective in visualizing any architectural design is to achieve a situational awareness that allows for meaningful criticism of the design. Computer-aided three-dimensional (3D) visualization technology has made available new representation techniques. Surpassing the traditional means of graphic illustration and scaled models, this technology has been primarily developed to decrease the amount of abstraction between architecture and its documentation. The general objective of this paper is to present a study carried out over the last six years in which the progress of students in a traditional studio was compared to the progress of similar students in a digital studio. We have assessed the effects of the tools over the six-year period (24 different projects) by evaluating solution-generation in trial-and-error process and learning problem-solving strategies based on the Cognitive Flexibility Theory paradigm. Students using the digital studio were found to generate more and various solutions consistently.

summary	This paper presents a case study of the application of computer techniques for design communication and visual impact analysis. We were sponsored by China Light & Power Company Ltd. To simulate the design of a proposed electricity substation and its it is setting in a residential neighborhood. During a five-week intensive study, we took nearly one thousand photographs of the existing site. We also created a three-dimensional CAD model of the proposed substation, and produced perspectives from points of view analogous to the photographs. We applied Apple Quicktime VR technology to document the site environment with 360-degree panoramas. We then montaged the computer-generated panoramas with those taken from the real environment. A navigable virtual environment, architectural animation and set of still images were presented to the public in September 1998. The reactions from the regional council members and local residents nearby were recorded to provide evidence to measure the effectiveness of digital architectural design communication.

summary	In this paper, we describe a semi-automatic reconstruction method of a three-dimensional model from orthographic view drawings of architecture. There are several approaches to reconstruct three-dimensional solids from two-dimensional drawings. But most of them deal with mechanical drawings, not architectural drawings. We observed three-dimensional modeling process of design practice and we tried to make clear model-ing procedure from architectural drawings, such as plan and elevation views, and classified into seven typical modeling operations on three-dimensional CAD system. Then we pro-posed a reconstruction method to create a surface three-dimensional model from a set of architectural plan and elevation drawings. Each elevation drawing is defined as polygon elements. The reconstruction system makes each element of elevations built up and then placed each around the contour of the plan drawing. Several illustrative examples are in-cluded as results.

summary	A traditional way to present three-dimensional representations of architectural design has been through the use of manually drawn perspective drawings. The perspective representation assists in the comprehension of the forms and spaces, but is difficult to manually generate. The computer revolution made perspectives much easier to generate and led to a dramatically increased use of three-dimensional representation as a presentation technique. We are just now seeing substantial uses of animation as a communication and presentation tool in architecture. This paper documents the results of two surveys of the architectural profession that sought to discover the current and near future intentions for the use of computer animation. Our belief is that current levels of computer animation use are low, but that many firms intend to start using animation both as a design and presentation tool. In early 1998 we conducted a survey of the uses of computer animation by architectural firms. We posited a set of 14 related hypotheses. This paper represents the tabulated results from 82 completed surveys out of 620 requests. While some level of confidence can be obtained from this sample size, we are publishing in the hope of encouraging continued response to the survey.

summary	Modeling the formal idea has long been problematic in schools. Renaissance tools, however inspired by the invention of perspective, usually result in two-dimensional sketches. Cardboard and small pieces of wood occasionally become the three-dimensional media of first visualization in studios; modeling on the computer is a newer idea. This paper examines two experiments, one where design fundamentals and solid modeling are introduced in a common studio, the other where instruction is removed from the studio environment and made an adjunct elective. In the first case the course is an introduction to both design and computation, an electronic investigation of Paul Klee’s first principles: point, line, shape, form and space—adding, subtracting, rotating and multiplying objects using Beaux Arts principles to create the design. The result is architectural form-making that was not possible in the studio-past. The second case is a course which isolates computer instruction from the studio, making it a separate academic discipline. Fantasy projects then demonstrate computational principle, exploring pure form without burden of technical or social obligation that studio imposes; alternative methods are presented for introducing design computation to the architectural student.

summary	This paper explains the three-dimensional representation procedure of one fragment of Mil· house elevation designed by the architect Antoni GaudÌ. The generation process of an architectonic virtual model constituted by free form surfaces like this, represents a paradigm of high level difficulty in CAD modeling. The main objective of our research has been not only construct a model that shows the complex form of its architecture, but also verify the performance of the different tools supported by computer aided design programs in the management of surface modeling.We obtained an accurate information of the real surface elevation with a photogrammetric survey using contour lines. The transformation of this kind of data in a three-dimensional model was not immediately Thus, we have had study different ways to generate the three-dimensional model solution. The process began with the construction of different surface models supported by analytic functions, but the obtained surfaces made with this system were deficient and not too much satisfactory. That's why, we use a polyhedron mesh surface method in order to improve these results.in spite of this methodology reductive performance, (compared with analytic function systems), the obtained surface demonstrated that this technique was the best way to satisfy the requirement of a free form surface previously established as we want to construct. From this point the principal problem was generate a surface defined by two-dimensional data, (contour lines), applying an automatic process sufficiently fast to compete with the analytic function systems.To satisfy the demand was necessary make complementary software to improve the process and allow more fluidity to resolve this typology of surfaces. We achieved this phase thanks to Joan Miquel Quilez collaboration and the constant dedication in the elaboration of complementary software to computer aided design. Finally, the introduction of render systems with lights, shadows, textures and reflected images, allowed show the studied elevation area of Mil· house with more accuracy. Thus, the limits and contours of the finally surface were more evident and help us to known the properties of a non- materialized free form surface successfully.
