abstract

Results on data visualization from TU Eindhoven are presented. Applications, methods and images vary strongly, the linking theme is the use of graphics techniques to depict data as clearly as possible.

Flow can be visualized as moving textures, graphics hardware can be exploited to do this in real time. Hierarchical data, such as file systems, can be shown in many ways. Abstract representations, such as treemaps, can be enhanced by using shaded geometry, but also, direct botanical metaphors can be used. Finally, recent results from mathematical visualization are shown. A Seifert surface is an oriented surface that is bounded by a (mathematical) knot. Such a surface exists for any knot, but what does it look like?

All these topics will be illustrated with live demos.
