PASSPORT post-doc topic

Surface and volume reconstruction of blood vessels with guaranteed geometry and topology

Ph.D. thesis

Title: Feature Based Visualization

Advisor: Prof. Dr. Hans Hagen et Prof. Dr. Charles Hansen (co-advisor).

When and where: defense on December 14., 2007 at the University of Kaiserslautern.

Abstract:

In this thesis we applied powerful mathematical tools such as interval arithmetic for applications in computational geometry, visualization and computer graphics, leading to robust, general and efficient algorithms. We presented a completely novel approach for computing the arrangement of arbitrary implicit planar curves and performed ray casting of arbitrary implicit functions by jointly achieving, for the first time, robustness, efficiency and flexibility. Indeed we were able to render even the most difficult implicits in real-time with guaranteed topology and at high resolution. We used subdivision and interval arithmetic as key-ingredients to guarantee robustness. The presented framework is also well-suited for applications to large and unstructured data sets due to the inherent adaptivity of the techniques that are used. We also approached the topic of tensors by collaborating with mechanical engineers on comparative tensor visualization and provided them with helpful visualization schemes to interpret the data.
