Scientific Visualization Of Physical Phenomena

Scientific Visualization of Physical Phenomena reflects the special emphasis of the Computer Graphics Society's Ninth International Conference, held at the MIT in Cambridge, Massachusetts, USA in June, 1991. This volume contains the proceedings of the conference, which, since its foundation in 1983, continues to attract high quality research articles in all aspects of Computer Graphics and its applications. Visualization in science and engineering is rapidly developing into a vital area because of its potential for significantly contributing to the understanding of physical processes and the design automation of man-made systems. With the increasing emphasis in handling complicated physical and artificial processes and systems and with continuing advances in specialized graphics hardware and processing software and algorithms, visualization is expected to play an increasingly dominant role in the foreseeable future.

Scientific visualization is concerned with exploring data and information insuch a way as to gain understanding and insight into the data. This is a fundamental objective of much scientific investigation. To achieve this goal, scientific visualization utilises aspects in the areas of computergraphics, user-interface methodology, image processing, system design, and signal processing. This volume is intended for readers new to the field and who require a quick and easy-to-read summary of what scientific visualization is and what it can do. Written in a popular andjournalistic style with many illustrations it will enable readers to appreciate the benefits of scientific visualization and how current tools can be exploited in many application areas. This volume is indispensible for scientists and research workers who have never used computer graphics or other visual tools before, and who wish to find out the benefitsand advantages of the new approaches.

This volume is on "modem geometric computing for visualization" which is at the forefront of multi-disciplinary advanced research areas. This area is attracting intensive research interest across many application fields: singularity in cosmology, turbulence in ocean engineering, high energy physics, molecular dynamics, environmental problems, modem mathe matics, computer graphics, and pattern recognition. Visualization re quires the computation of displayable shapes which are becoming more and more complex in proportion to the complexity of the objects and phenomena visualized. Fast computation requires information locality. Attaining information locality is achieved through characterizing the shapes in geometry and topology, and the large amount of computation required through the use of supercomputers. This volume contains the initial results of our efforts to satisfy these re quirements by inviting experts and selecting new research works through review processes. To be more specific, this book presents the proceedings of the International Workshop on Modem Geometric Computing for Visualization held at Kogakuin University, Tokyo, Japan, June 29-30, 1992 organized by the Computer Graphics Society, Japan Personal Com puter Software Association, Kogakuin University, and the Department of Information Science, Faculty of Science, The University of Tokyo. We received extremely high-quality papers for review from five different countries, one from Australia, one from Italy, four from Japan, one from Singapore and three from the United States, and we accepted eight papers and rejected two.

One of the important issues of Scientific Visualization is the utilization of the broad bandwidth of the human sensory system in steering and interpreting complex processes and simulations involving voluminous data sets across diverse scientific disciplines. This book presents the state-of-the-art in visualization techniques both as an overview for the inquiring scientist, and as a solid platform from which developers may extend existing techniques or devise new ones to meet the specific needs of their problems. A secondary goal in crafting this volume has been to provide a vehicle for teaching of state-of-the-art techniques in scientific visualization. The first part of the book covers the application areas fluid flow visualization in medicine, and environmental protection. The second set of chapters explain fundamentals of scientific visualization. It comprises contributions on data structuring and data administration, data modeling, and rendering. A final section is devoted to auditory representation of scientific data.

Visualization is now recognized as a powerful approach to get insight in large datasets produced by scientific experimentations and simulations. The contributions to this book cover technical aspects as well as concrete applications of visualization in various domains such as finance, physics, astronomy and medicine, providing researchers and engineers with valuable information for setting up new powerful environments.

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.
