This project deals with the visualization of simulations of Rosetta's target comet 67P/Churyumov-Gerasimenko. Various flow visualization and feature detection algorithms are applied to the data. One goal is to extract the shock wave and the inner cavity. In a second part of this project simulation data of an adiabatic collaps of a cloud core will be analysed. Since the data is high-dimensional, especially information visualization techniques are applied to create an overview of the data and to extract important features.
