Interactive Blood Flow Exploration – In collaboration with Dept. of Neurology, OVGU and Inria, France

In cerebral aneurysm research, CFD simulations allow us to gain a better understanding of the dynamics of the blood flow. The simulated flow is often visualized using integral curves resulting in cluttered “spaghetti plots”. Advanced approaches group similar curves and show only selected representatives (image). These approaches however, fail in showing the clusters’ spatial extent. In this thesis, an interactive approach facilitating a continuous transition between the full set of integral curves and an uncluttered abstracted visualization shall be developed. Browsing back and forth through various levels of abstraction shall allow the user to grasp both, the general structure of the blood flow pattern as well as the spatial extent of individual substructures.

Requirements: Good to very good programming skills (C++) are mandatory
