Visualization – Lecture

The content of the lecture is divided into three main parts.

• Part I: Basics – In this introductory part an overview of possible applications of computer-aided visualization is given by means of many examples. It should become clear which display possibilities exist and how they are combined. The examples are analyzed with regard to the techniques used and principles of computer-aided visualization are described. Subsequently, the basics of visual perception are treated. The first part is finished with a discussion of the underlying data, e.g., data structures, grid types, their advantages, disadvantages and resulting applications.

• Part II: Information Visualization – The second part describes basic visualization techniques and visualization techniques for abstract data (Information visualization). Basic techniques involve color coding and isolines. InfoVis comprises graph and network visualization, glyph-based visualization, other techniques for visualizing high-dimensional data, such as parallel coordinates and scatterplot matrices.

• Part III: 3D Visualization – In this area mainly volume visualization techniques and methods for flow visualization are described. In the field of volume visualization methods, the focus is on the representation of regular 3D-grids, as they are created, for example, in medicine by the imaging methods computed tomography and magnetic resonance imaging.
