The area of computer graphics is characterized by rapid evolution. New techniques in hardware and software developments, e. g. , new rendering methods, have led to new ap plications and broader acceptance of graphics in fields such as scientific visualization, multi-media applications, computer aided design, and virtual reality systems. The evolving functionality and the growing complexity of graphics algorithms and sys tems make it more difficult for the application programmer to take full advantage of these systems. Conventional programming methods are no longer suited to manage the increasing complexity, so new programming paradigms and system architectures are re quired. One important step in this direction is the introduction and use of object-oriented methods. Intuition teils us that visible graphical entities are objects, and experience has indeed shown that object-oriented software techniques are quite useful for graphics. The expressiveness of object-oriented languages compared to pure procedurallanguages gives the graphics application programmer much better support when transforming his mental intentions into computer code. Moreover, object-oriented software development is a, weil founded technology, allowing software to be built from reusable and extensible compo nents. This book contains selected, reviewed and thoroughly revised vers ions of papers submit ted to and presented at the Fourth Eurographies Workshops on Object-Oriented Graphics, held on May 9-11, 1994 in Sintra, Portugal.

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.

1 Aims and Features of This Book The contents of t. his book were originally planned t. o be included in a book en titled Geometric lIIodeling and CAD/CAM to be written by M. Hosaka and F. Kimura, but since the draft. of my part of the book was finished much earlier than Kimura's, we decided to publish this part separately at first. In it, geometrically oriented basic methods and tools used for analysis and synthesis of curves and surfaces used in CAD/CAM, various expressions and manipulations of free-form surface patches and their connection, interference as well as their qualit. y eval uation are treated. They are important elements and procedures of geometric models. And construction and utilization of geometric models which include free-form surfaces are explained in the application examples, in which the meth ods and the techniques described in this book were used. In the succeeding book which Kimura is to write, advanced topics such as data structures of geometric models, non-manifold models, geometric inference as well as tolerance problems and product models, process planning and so on are to be included. Conse quently, the title of this book is changed to Modeling of Curves and Surfaces in CAD/CAM. Features of this book are the following. Though there are excellent text books in the same field such as G. Farin's Curves and Surfaces for CAD /CAM[l] and C. M.

This book contains a selection of revised versions of papers presented at the Third Eurographics Workshop on Intelligent CAD Systems, which was held at Hotel Opduin on the island of Texel in The Netherlands, April 3-7, 1989. The workshop theme was Practical Experience and Evaluation. It included five paper presentation sessions, each followed by a discussion. The workshop closed with a general discussion. The book is therefore divided into five parts: design process, system architecture, languages, geometric reasoning, and user interface. A report on the discussion session, written by the session's moderator, concludes each part. These reports are not intended to be exact records of the discussion, but rather the moderators' summary of their contents. The aim of the workshop was to share the experience the participants gained by developing intelligent CAD (Computer Aided Design) systems, and to evaluate the developed systems to determine which features were still lacking. The workshop was organized as the last one in a series of three workshops under the same title. The first workshop focused on theoretical and methodological aspects, resulting in a sound theoretical basis for intelligent CAD systems. Implementational issues were discussed at the second workshop, paying attention to systems developed with reference to this basis. The experience and evaluation showed a dual outcome. Firstly, it resulted in the development of a new generation of intelligent CAD systems. Secondly, it led us to the development of new theories for intelligent CAD.

This book is a result of the lectures and discussions during the conference "Theory and Practice of Geometric Modeling". The event has been organized by the Wilhelm-Schickard-Institut fiir Informatik, Universitat Tiibingen and took place at the Heinrich-Fabri-Institut in Blaubeuren from October 3 to 7, 1988. The conference brought together leading experts from academic and industrial research institutions, CAD system developers and experien ced users to exchange their ideas and to discuss new concepts and future directions in geometric modeling. The main intention has been to bridge the gap between theoretical results, performance of existing CAD systems and the real problems of users. The contents is structured in five parts: A Algorithmic Aspects B Surface Intersection, Blending, Ray Tracing C Geometric Tools D Different Representation Schemes in Solid Modeling E Product Modeling in High Level Specifications The material presented in this book reflects the current state of the art in geometric modeling and should therefore be of interest not only to university and industry researchers, but also to system developers and practitioners who wish to keep up to date on recent advances and new concepts in this rapidly expanding field. The editors express their sincere appreciation to the contributing authors, and to the members of the program committee, W. Boehm, J. Hoschek, A. Massabo, H. Nowacki, M. Pratt, J. Rossignac, T. Sederberg and W. Tiller, for their close cooperation and their time and effort that made the conference and this book a success.

This book presents important results from the ESPRIT Project 393 "Construction and Interrogation of Knowledge Bases Using Natural Language Text and Graphics" (ACORD). The project involved more than fifty people overfive years, and included industrial and academic partners from three countries. The main result of the project is a highly sophisticated human-machine interface allowing the construction and interrogation of a common knowledge base in English, French, and German, using both natural language and graphics. Chapter 1 presents an overview of the project. Chapters 2-4 develop specific issues concerning thegrammar models used (functional grammars and unification categorial grammars). Chapter 5 discusses anaphora resolution and Chapter 6 text generation. Chapter 7 explains the integration of text and graphics, and Chapter 8 discusses the knowledge base module. The contributions are theoretically oriented and strongly concerned with generalization and the underlying background of potential further developments.
