Mathematical Visualization is a young new discipline. It offers efficient visualization tools to the classical subjects of mathematics, and applies mathematical techniques to problems in computer graphics and scientific visualization. Originally, mathematical visualization started in the interdisciplinary area of differential geometry, numerical mathematics, and computer graphics. In recent years, the methods developed have found important applications, and the subject has evolved to a discipline in its own right. The current volume is the quintessence of an international workshop in September 1997in Berlin, focusing on recent developments in this emerging area. Experts present selected research work on new algorithms for visualization problems, describe the application and experiments in geometry, and develop new numerical or computer graphical techniques. The sections of the book contain topics on Meshes in Numerics and Visualization, Applications in Geometry and Numerics, Graphics Algorithms and Implementations, Geometric Visualization Techniques, and Vectorfields and Flow Visualization. The book is the second in a series of publications on this subject. It offers the reader insight to latest research and developments in this fascinating new area.
