Phigs Workstation

  phigs workstation: PHIGS by Example William A. Gaman, William A. Giovinazzo, 2012-12-06 The Programmer's Hierarchical Interactive Graphics System (PHIGS) is a computer-graphics standard defining an interface between an application program and a computer-graphics system. PHIGS has been actively under development since 1980. Much of this development has been performed by Technical Committee X3H3 under the American National Standard Institute (ANSI) procedures. PHIGS is also an international standard sponsored by the United States and developed by the international computer-graphics committee, ISO TC97/SC21/WG2. In addition, PHIGS has been selected as the graphics extension to the X-window standard and as part of the Intel i860 P.A.X. standard. The PHIGS standard has received wide acceptance throughout the computer graphics industry. PHIGS libraries are available on most of the high performance three-dimensional graphics platforms. These include IBM, DEC, HP, Sun, Alliant, Stardent, and Silicon Graphics. Despite this acceptance, there are few texts that provide the software engineer with an overview of the standard. The only currently available PHIGS references are in the form of the ANSI functional description, technical papers, and device-specific PHIGS to the novice PHIGS programmer.

  phigs workstation: Visual Computing Tosiyasu L. Kunii, 2013-04-17 This volume presents the proceedings of the 10th International Conference of the Computer Graphics Society, CG International '92, Visual Computing - Integrating Computer Graphics with Computer Vision -, held at Kogakuin University, Tokyo in Japan from June 22-26,1992. Since its foundation in 1983, this conference has continued to attract high quality research articles in all aspects of computer graphics and its applications. Previous conferences in this series were held in Japan (1983-1987), in Switzerland (1988), in the United Kingdom (1989), in Singapore (1990), and in the United States of America (1991). Future CG International conferences are planned in Switzerland (1993), in Australia (1994), and in the United Kingdom (1995). It has been the editor's dream to research the integration of computer graphics with computer vision through data structures. The conference the editor put together in Los Angeles in 1975 involving the UCLA and IEEE Computer Societies had to spell out these three areas explicitly in the conference title, computer graphics, pattern recognition and data structures, as well as in the title of the proceedings published by IEEE Computer Society Press. In 1985, the editor gave the name visual computer to machines having all the three functionalities as seen in the journal under that name from Springer. Finally, the research in integrating visual information processing has now reached reality as seen in this proceedings of CG International '92. Chapters on virtual reality, and on tools and environments provide examples.

  phigs workstation: The Data Handbook Brand Fortner, 2012-12-06 What our teachers don't tell us in school is that we will spend most of our scientific or engineering career in front of computers, trying to beat them into submission. My formal training in computational science is nil, which I suspect is true of 90 percent of the scientists and engineers in the world. In this book, I attempt to bring together in one place the very basic facts that every technical person should know about computers. The computers of today still require you to know quite a bit about them in order to use them effectively for technical data analysis. Scientists and engineers who are computer novices should read this book cover to cover (that is, in my modest opinion). Experienced computer users should use this book as a reference. There are nuggets of useful information in this book waiting to be discovered by even the most computer-literate of you. Changes in the Second Edition Numerous corrections and clarifications were made throughout the text. Thanks to all of you who sent in your comments on the first edition. In addition, the index and glossary have been greatly improved.

COl '88 is the Official Annual Conference of the Computer Graphics Society. Since 1982, this conference ha~ been held in Tokyo. This year, it is taking place in Geneva, Switzerland. In 1989, it will be held in Leeds, U. K. , in 1990 in Singapore, in 1991 in U. S. A. and in 1992 in Montreal, Canada. Over 100 papers were submitted to CGI '88 and 61 papers were selected by the International Program Committee. Papers have been grouped into 6 chapters. The flrst chapter is dedicated to Computer Animation because it deals with all topics presented in the other chapters. Several animation systems are described as well as speciflc subjects like 3D character animation, quaternions and splines. The second chapter is dedicated to papers on Image Synthesis, il1 particular new shading models and new algorithms for ray tracing are presented. Chapter 3 presents several algorithms for geometric modeling and new techniques for the creation and manipulation of curves, surfaces and solids and their applications to CAD. In Chapter 4, an important topic is presented: the specification of graphics systems and images using l~nguages and user-interfaces. The last two chapters are devoted to applications in sciences, medicine, engineering, art and business.
  phigs workstation: Advances in Computer Graphics IV W.T. Hewitt, Michel Grave, Michel Roch, 2012-12-06 This fourth volume of Advances in Computer Graphics gathers together a selection of the tutorials presented at the EUROGRAPHICS annual conference in Nice, France, Septem ber 1988. The six contributions cover various disciplines in Computer Graphics, giving either an in-depth view of a specific topic or an updated overview of a large area. Chapter 1, Object-oriented Computer Graphics, introduces the concepts of object ori ented programming and shows how they can be applied in different fields of Computer Graphics, such as modelling, animation and user interface design. Finally, it provides an extensive bibliography for those who want to know more about this fast growing subject. Chapter 2, Projective Geometry and Computer Graphics, is a detailed presentation of the mathematics of projective geometry, which serves as the mathematical background for all graphic packages, including GKS, GKS-3D and PRIGS. This useful paper gives in a single document information formerly scattered throughout the literature and can be used as a reference for those who have to implement graphics and CAD systems. Chapter 3, GKS-3D and PHIGS: Theory and Practice, describes both standards for 3D graphics, and shows how each of them is better adapted in different typical applications. It provides answers to those who have to choose a basic 3D graphics library for their developments, or to people who have to define their future policy for graphics.
  phigs workstation: Computer Aided Design Jose L. Encarnacao, Rolf Lindner, Ernst G. Schlechtendahl, 2012-12-06 2 e This book describes principles, methods and tools that are common to computer applications for design tasks. CAD is considered in this book as a discipline that provides the required know-how in computer hardware and software, in systems analysis and in engineering methodology for specifying, designing, implementing, introducing, and using computer based systems for design purposes. The first chapter gives an impression of the book as a whole, and following chapters deal with the history and the components of CAD, the process aspect of CAD, CAD architecture, graphical devices and systems, CAD engineering methods, CAD data transfer, and application examples. The flood of new developments in the field and the success of the first edition of this book have led the authors to prepare this completely revised, updated and extended second edition. Extensive new material is included on computer graphics, implementation methodology and CAD data transfer; the material on graphics standards is updated. The book is aimed primarily at engineers who design or install CAD systems. It is also intended for students who seek a broad fundamental background in CAD.
  phigs workstation: Scientific Visualization K.W. Brodlie, L.A. Carpenter, R.A. Earnshaw, J.R. Gallop, R.J. Hubbold, A.M. Mumford, C.D. Osland, P. Quarendon, 2012-12-06 Background A group of UKexperts on Scientific Visualization and its associated applications gathered at The Cosener's House in Abingdon, Oxford shire (UK) in February 1991 to consider all aspects of scientific visualization and to produce a number of documents: • a detailed summary of current knowledge, techniques and appli cations in the field (this book); • an Introductory Guide to Visualization that could be widely dis tributed to the UK academic community as an encouragement to use visualization techniques and tools in their work; • a Management Report (to the UK Advisory Group On Computer Graphics - AGOCG) documenting the principal results of the workshop and making recommendations as appropriate. This book proposes a framework through which scientific visualiza tion systems may be understood and their capabilities described. It then provides overviews of the techniques, data facilities and human-computer interface that are required in a scientific visualiza tion system. The ways in which scientific visualization has been applied to a wide range of applications is reviewed and the available products that are scientific visualization systems or contribute to sci entific visualization systems are described. The book is completed by a comprehensive bibliography of literature relevant to scientific visualization and a glossary of terms. VI Scientific Visualization Acknowledgements This book was predominantly written during the workshop in Abingdon. The participants started from an input document pro duced by Ken Brodlie, Lesley Ann Carpenter, Rae Earnshaw, Julian Gallop (with Janet Haswell), Chris Osland and Peter Quarendon.
  phigs workstation: Design of Office Information Systems Clarence A. Ellis, Najah Naffah, 2012-12-06 The goal of this book is to present a framework within which the myriad of office technologies and office systems design techniques can be better understood. There are a number of office books which deal with the social/organizational aspects of office automation or with office equip ment introduction strategies. This book differs from those in that it is written by technical computer people for technical computer people. As such, it assumes a general computer literacy and contains a technical emphasis with a social fiber woven in. Besides the framework, we also present the current state of office primitives, office tools, and office tech nology. We cover relevant work on-going by international standards bod ies, and we discuss the concepts that are emerging (or which we feel will be emerging) from universities and industrial research laboratories. Office technologies and techniques are classified as personal environment aids versus communal environment aids. We now fully realize how difficult it is to write a coherent book within this fuzzy, interdisciplinary, rapidly changing field. Concepts have been stressed wherever possible; there are some sub-areas where the generaliz ing concepts have not yet emerged. We also realize the potential danger of obsolescense. We have tried to combate this somewhat by the presen tation of concepts, generic tool design, and emphasizing our framework. This book is not a substitute for reading of the current periodical litera ture - that is where the most timely information lies.
  phigs workstation: Computers and Informatics in Developing Countries D.B. Arnold, D.A.

The fourth part tackles validation and testing; conformance testing of graphic standards; and the registration of graphical items. The book also discusses the status and future direction of ISO standards for computer graphics; it also presents in the last part the bibliography of the included topics, glossary on related bodies, and the formal specification of a part of GKS. The text is recommended for computer engineers, IT experts, and graphic designers who would like to know the ISO standards for computer graphics and its implications in their practice.
  phigs workstation: Visualization in Scientific Computing Michel Grave, Yvon Le Lous, W.Terry Hewitt, 2012-12-06 Visualization in scientific computing is getting more and more attention from many people. Especially in relation with the fast increase of com puting power, graphic tools are required in many cases for interpreting and presenting the results of various simulations, or for analyzing physical phenomena. The Eurographics Working Group on Visualization in Scientific Com puting has therefore organized a first workshop at Electricite de France (Clamart) in cooperation with ONERA (Chatillon). A wide range of pa pers were selected in order to cover most of the topics of interest for the members of the group, for this first edition, and 26 of them were presented in two days. Subsequently 18 papers were selected for this volume. 1'he presentations were organized in eight small sessions, in addition to discussions in small subgroups. The first two sessions were dedicated to the specific needs for visualization in computational sciences: the need for graphics support in large computing centres and high performance net works, needs of research and education in universities and academic cen tres, and the need for effective and efficient ways of integrating numerical computations or experimental data and graphics. Three of those papers are in Part I of this book. The third session discussed the importance and difficulties of using stan dards in visualization software, and was related to the fourth session where some reference models and distributed graphics systems were discussed. Part II has five papers from these sessions.

  phigs workstation: GKS Theory and Practice Peter R. Bono, Ivan Herman, 2012-12-06 Eurographics, the European Association for Computer Graphics, has always been an important forum for discussions and presentation of results concerning the first ISO Graphical Standard, GKS (the Graphical Kernel System) and later of its three-dimensional extension, GKS-3D. This book is a collection of those articles which have appeared within the framework of Eurographics in the past 5 years, and which still contain, even after several years, valid and interesting results concerning the problems arising in connection with GKS. Some of these papers help the reader to gain a deeper understanding of the standard; others deal with general implementation problems, and finally there are some presentations of specific algorithms usable also for a GKS or GKS-3D implementation. The book may be of a particular interest to those specialists who intend to implement a GKS package or some similar graphics subsystem and who can therefore make direct use of the experiences reflected in this collection. The book should also be a valuable supplement in university courses concerned with teaching the principles of implementing device-independent computer graphics.
  phigs workstation: Computer Graphics Techniques David F. Rogers, Rae Earnshaw, 2001-10-31 In the third paper in this chapter, Mike Pratt provides an historical intro duction to solid modeling. He presents the development of the three most freqently used techniques: cellular subdivision, constructive solid modeling and boundary representation. Although each of these techniques devel oped more or less independently, today the designer's needs dictate that a successful system allows access to all of these methods. For example, sculptured surfaces are generally represented using a boundary represen tation. However, the design of a complex vehicle generally dictates that a sculptured surface representation is most efficient for the 'skin' while constructive solid geometry representation is most efficent for the inter nal mechanism. Pratt also discusses the emerging concept of design by 'feature line'. Finally, he addresses the very important problem of data exchange between solid modeling systems and the progress that is being made towards developing an international standard. With the advent of reasonably low cost scientific workstations with rea sonable to outstanding graphics capabilities, scientists and engineers are increasingly turning to computer analysis for answers to fundamental ques tions and to computer graphics for present~tion of those answers. Although the current crop of workstations exhibit quite impressive computational ca pability, they are still not capable of solving many problems in a reasonable time frame, e. g. , executing computational fluid dynamics and finite element codes or generating complex ray traced or radiosity based images. In the sixth chapter Mike Muuss of the U. S.

  phigs workstation: Advances in Computer Graphics I Günter Enderle, Michel Grave, Frank Lillehagen, 2013-06-29 This book is the sixth issue in the EurographicSeminars Series. This series has been set up by Eurographics, the European Association for Computer Graphics, in order to disseminate surveys and research results out of the field of Computer Graphics. Computer Graphics constitute a powerful and versatile tool for various application areas. The rapidly increasing use of Computer Graphics techniques and systems in many areas is caused by the availability of more powerful hardware at lower prices,' by the concise specification of Computer Graphics Interfaces in commonly·.agreed standards, and by the inven tion of new and often astonishing methods and algorithms for com position andpreserit~ti6n of pictJres and for graphical interaction. While s,o~e issues of this se.ries contain latest research results, e.g. the issues in window management systems or user interface manage ment systems, this book has the character of a state-of-the-art survey on important areas .of Computer Graphics. Starting from current practice and agreed consens, it will lead to the latest achievements in this field. The contributions in this issue are largely based on tutorials and seminars held at the Eurographics conferences 1984 in Copen hagen and 1985 in Nice.

  phigs workstation: CGM and CGI David B. Arnold, Peter R. Bono, 2012-12-06 We have written this book principally for users and practitioners of computer graphics. In particular, system designers, independent software vendors, graphics system implementers, and application program developers need to understand the basic standards being put in place at the so-called Virtual Device Interface and how they relate to other industry standards, both formal and de facto. Secondarily, the book has been targetted at technical managers and advanced students who need some understanding of the graphics standards and how they fit together, along with a good overview of the Computer Graphics Interface (CGI) proposal and Computer Graphics Metafile (CGM) standard in particular. Part I, Chapters 1,2, and 3; Part II, Chapters 10 and 11; Part III, Chapters 15, 16, and 17; and some of the Appendices will be of special interest. Finally, these same sections will interest users in government and industry who are responsible for selecting, buying and installing commercial implementations of the standards. The CGM is already a US Federal Information Processing Standard (FIPS 126), and we expect the same status for the CGI when its development is completed and it receives formal approval by the standards-making bodies.
  phigs workstation: The Computer Graphics Metafile L.R. Henderson, A.M. Mumford, 2014-05-20 The Computer Graphics Metafile deals with the Computer Graphics Metafile (CGM) standard and covers topics ranging from the structure and contents of a metafile to CGM functionality, metafile elements, and real-world applications of CGM. Binary Encoding, Character Encoding, application profiles, and implementations are also discussed. This book is comprised of 18 chapters divided into five sections and begins with an overview of the CGM standard and how it can meet some of the requirements for storage of graphical data within a graphics system or application environment. The reader is then introduced to the practice of using the CGM and the nature of the CGM, its aims, and what is defined in the standard. The following chapters focus on the players, the rules, and the game; the abstract functionality of the CGM; descriptor elements for metafiles and pictures; coordinates, primitives, and attributes; and encodings and implementation considerations. Clear Text Encoding, Binary Encoding, Character Encoding, and application profiles are also explored. The final chapter looks at the use of GKS, GKS-3D, and PHIGS to generate and interpret CGMs. This monograph will be a valuable resource for computer graphics students and professionals as well as software engineers and computer programmers.
  phigs workstation: User Interface Management and Design David A. Duce, M. Rui Gomes, F. Robert A. Hopgood, John R. Lee, 2012-12-06 This volume is a record of the Workshop on User Interface Management Systems and Environments held at INESC, Lisbon, Portugal, between 4 and 6 June 1990. The main impetus for the workshop came from the Graphics and Interaction in ESPRIT Technical Interest Group of the European Community ESPRIT Programme. The Graphics and Interac tion in ESPRIT Technical Interest Group arose from a meeting of researchers held in Brussels in May 1988, which identified a number of technical areas of common interest across a significant number of ESPRIT I and ESPRIT II projects. It was recognized that there was a need to share information on such activities between projects, to disseminate results from the projects to the world at large, and for projects to be aware of related activities elsewhere in the world. The need for a Technical Interest Group was confirmed at a meeting held during ESPRIT Technical Week in November 1989, attended by over 50 representatives from ESPRIT projects and the Commission of the European Communities. Information exchange sessions were organized during the EUROGRAPHICS '89 confer ence, with the intention of disseminating information from ESPRIT projects to the wider research and development community, both in Europe and beyond.
  phigs workstation: Computer Graphics and Geometric Modeling for Engineers Vera B. Anand, 1993-02-05 Computer graphics and geometric modeling play a fundamental role in instruction for engineering design. It is an acknowledged fact that the computer is needed for data storage and numerical processing. Computer-aided modeling, on the other hand, strengthens the engineer's ability to think through a design, because it eases the process of establishing both conceptual trade-offs at the preliminary design stage, and the choice of parts to bracket a specific design. Computer graphics allows a full description of an engineering component to be stored in a CAD system This captures both the visual and quantitative aspects of object creation. Geometric modeling describes an object by means of mathematical and abstract relationships, and focuses on the efficient computer representation of geometry. Both are integral parts of the engineering education process. This textbook teaches the basic principles and techniques of computer graphics and geometric modeling from the point of view of engineering applications. The text is, therefore, aimed for engineers, although some generic computer graphics topics are also covered, since they are needed as background information essential to an overall understanding of the material. It is designed as a one- or two-semester course at the junior, senior, or graduate levels.

  phigs workstation: UIPEX Parris Karl Egbert, 1990 Abstract: In an attempt to provide powerful 3D graphics in a windowing environment, PHIGS, PHIGS PLUS, and PEX have been developed. PHIGS and PHIGS PLUS provide an environment for producing complex 3D images. PEX incorporates this environment into the X Window system. This thesis discusses UIPEX -- the University of Illinois implementation of PEX. The main focus of the thesis is on the implementation of the application programmer interface level. Implementation issues and alternatives are discussed, as well as the rationale behind decisions that were made in the implementation. In addition, a critique of PHIGS is given with possible alternatives for overcoming some of the inherent weaknesses in PHIGS.
  phigs workstation: Product Data Interfaces in CAD/CAM Applications J. Encarnacao, R. Schuster, E. Vöge, 2012-12-06 Interest in product data exchange and interfaces in the CAD/CAM area is steadi ly growing. The rapidly increasing graphics applications in engineering and sci ence has led to a great variety of heterogeneous hardware and software products. This has become a major obstacle in the progress of systems integration. To improve this situation CAD/CAM users have called for specification and imple mentation of standardized product data interfaces. These needs resulted in the definition of preliminary standards in this area. Since 1975 activities have been concentrated on developing standards for three major areas: - computer graphics, - sculptured surfaces, and - data exchange for engineering drawings. The Graphical Kernel System (GKS) has been accepted as an international standard for graphics programming in 1984, Y14.26M (IGES) was adopted as an American Standard in 1981 and the VDA Surface Interface (VDAFS) has been accepted by the German National Standardization Institute (DIN NAM 96.4). Although considerable progress has been achieved, the complexity of the subject and the dynamics of the CAD/CAM-development still calls for more generality and compatibility of the interfaces. This has resulted in an inter national discussion on further improvements of the standards. The major goal of this book is to bring together the different views and experiences in industry and university in the area of Product Data Interfaces, thereby contributing to the ongoing work in improving the state of the art.

  phigs workstation: Advances in Computer Graphics V Werner Purgathofer, Jürgen Schönhut, 2012-12-06 This book collects together several of the tutorials held at EUROGRAPHICS'89 in Hamburg. The conference was held under the motto Integration, Visualisation, Interaction and the tutorials reflect the conference theme. The Springer series EurographicSeminars with the volumes Advances in Computer Graphics regularly provides a professional update on current mainstream topics in the field. These publications give readers the opportunity to inform themselves thoroughly on the topics covered. The success of the series is mainly based on the expertise of the contributing authors, who are recognized professionals in their field. Starting out with one of the conference's main topics, the chapter Visualization of Scientific Data gives an overview of methods for displaying scientific results in an easily surveyable and comprehensible form. It presents algorithms and methods utilized to achieve visualization results in a form adequate for humans. User interfaces for such systems are also explored, and practical conclusions are drawn. The chapter Color in Computer Graphics describes the problems of manipulating and matching color in the real world. After some fundamental statements about color models and their relationships, the main emphasis is placed on the problem of objective color specification for computer graphics systems. It is very hard to match colors between devices such as scanners, printers and displays. Some suggestions on the effective use of color for graphics are also made.
  phigs workstation: Computer Aided Design and Manufacturing M.M.M. SARCAR, K. MALLIKARJUNA RAO, K. LALIT NARAYAN, 2008-05-05 The impact of the technology of Computer-Aided Design and Manufacturing in automobile engineering, marine engineering and aerospace engineering has been tremendous.
