Über dieses Buch

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.



Chapter 1. Introduction

Scientific Visualization is concerned with exploring data and information in such a way as to gain understanding and insight into the data.
Rae Earnshaw

Chapter 2. Framework

There are many different meanings of the word visualization. Outside the domain of computer graphics, accepted definitions include
  • making visible, especially to one’s mind (thing not visible to the eye) [OED69],
  • forming a mental image of something (thing not present to the sight, an abstraction, etc.) [Webster70].
Chris Osland

Chapter 3. Visualization Techniques

The previous chapter identified the concept of a Visualization Technique module which is responsible for generating and manipulating a graphic representation from a set of data, allowing investigation through user interaction. The purpose of this chapter is to describe this concept in some detail.
Ken Brodlie

Chapter 4. Data Facilities

This quote taken directly from [McCormick87] well illustrates one of the major problems in developing effective visualization software and techniques; that of efficiently handling and processing vast amounts of data. Since 1987 the necessary technologies and hardware to analyse and present the information in ways which are useful to the scientist have moved forward but the need for an efficient data handling methodology remains at the crux of the visualization initiative.
Lesley Ann Carpenter

Chapter 5. Human-Computer Interface

This chapter deals with Human-Computer Interface (HCI) issues in relation to visualization. Following the introductory sections, the chapter is structured into two main parts: first, user issues are addressed, relating to cognition, perception, human factors and organization, then system issues are highlighted in the context of these user requirements. The chapter concludes with recommendations for future work.
Roger Hubbold

Chapter 6. Applications

This chapter gives some examples which illustrate practical applications of visualization methods and experiences with them in a variety of fields. It shows which methods are being applied to the solution of current problems and the motivation for their use. It also points out some of the difficulties which have been experienced. Thus it shows which areas are being well catered for by visualization methods and the areas where it is felt that gaps and shortcomings exist and where more development is still needed.
Peter Quarendon

Chapter 7. Products

Previous chapters have presented a number of aspects of scientific visualization. The purpose of this chapter is to provide a brief survey of current examples of visualization products.
Julian Gallop

Chapter 8. Conclusions

This volume has presented a distillation of current techniques and applications of scientific visualization. The coverage is not exhaustive, but the tools and techniques that are described are representative of current practices in these areas. Further work is continuing on many of the topics highlighted in this volume.
