Visualization in Scientific Computing

TL;DR: This paper examines three possible relations that might exist between internal and external visualization and argues that the design of external visualizations should be informed by research on internal visualization skills, and that the development of technologies for external visualization calls for more research on the nature of internal visualization abilities.

TL;DR: The system the authors have designed utilizes visually displayed graphic structures and a direct manipulation interface style to supply an integrated environment for retrieval to help overcome some of the difficulties of orientation and navigation in large information structures.

Abstract: This chapter presents an overview of techniques for visualization of fluid flow data. As a starting point, a brief introduction to experimental flow visualization is given. The rest of the chapter concentrates on computer graphics flow visualization. A pipeline model of the flow visualization process is used as a basis for presentation. Conceptually, this process centres around visualization mapping, or the translation of physical flow parameters to visual representations. Starting from a set of standard mappings partly based on equivalents from experimental visualization, a number of data preparation techniques is described, to prepare the flow data for visualization. Next, a number of perceptual effects and rendering techniques are described, and some problems in visual presentation are discussed. The chapter ends with some concluding remarks and suggestions for future development.

TL;DR: A multidimensional ranking scheme based on the three dimensions of space, time, and theme is presented graphically to inform users about how well data sets from a digital spatial library meet their spatial, temporal, and thematic targets.
