In collaboration with Daniel Weiskopf - Development of a nearly fully automatic approach for generating interactive cutaway illustrations
Different approaches to generate cutaway illustrations have been investigated. The purpose of such a drawing is to allow the viewer to have a look into an otherwise solid opaque object. Traditional methods to draw these kinds of illustrations were evaluated to extract a small and effective set of rules for a computer-based rendering of cutaway illustrations. It was shown that our approaches are not limited to a specific rendering style but can be successfully combined with a great variety of well-known artistic or technical illustration techniques. The proposed methods make use of modern graphics hardware functionality to achieve interactive frame rates. At the current time an approach that uses DirectX8.1 compatible had been proposed.

In collaboration with Simon Stegmaier and Manfred Weiler - Improving the previously developed image-based remote rendering solution in diverse directions
With the advent of generic remote visualization solutions, acessing distant graphics resources from the desktop is no longer restricted to specially taylored applications. However the previous solution still suffered from poor interactivity due to limited network bandwith and high latency. We presented several improvements to the remote visualization system in order to overcome these drawbacks. Different image compression schemes are evaluated with regard to applicability for scientific visualization, showing that image compression alone cannot guarantee interactive frame rates. Therefore, furthermore different techniques for alleviating the bandwith limit, including quality reduction during user interaction or animations. Latency aspects were addressed by employing multi-threading for asynchronous compression and utilizing features of modern programmable graphic adapters for performing the image compression entirely on the graphics card.
