Here is an overview of my research projects in reverse order.

project - LOD based occlusion culling

From the university calendar (
"Occlusion culling is an important technique for handling large data sets with medium to high depth complexity. Recently, most graphics cards support occlusion queries, which return the number of visible pixels for a rendered object. This feature can be used to implement efficient occlusion culling techniques, which make good use of the bandwidth of modern graphics cards."

In this project, we reviewed current occlusion culling techniques for large data sets. Our goal was the development and implementation of a hardware-supported occlusion culling technique, which uses simplified models with different levels of detail to resolve the occlusion information.

project - haptical interfaces II

Haptical interfaces II was led by Prof. Dr. rer. nat. Bernd Fröhlich

Inertia Mouse Schema

We developed a new 3d input device for general purposes. With the help of accelerometer-sensors we can calculate the movement of the device, which is then transferred to the virtual object.

project - haptical interfaces I

Haptical interfaces I was led by Prof. Dr. rer. nat. Bernd Fröhlich and Dipl.-Inf.(FH) Jan Hochstrate WS 2003-2004.

This project deals with the developement of interfaces with the use of microprocessors like the AtMega32.
We implemented a new haptical interface for the forklifter game.

project - opengl and slang

opengl and slang was a project led by Prof. Christian Bucher and Prof. Dr. rer. nat. Bernd Fröhlich SS 2003.

The main goal was to develop an interactive interface for 3d visualisation of rigid bodies.
This was done using C/C++/qt/opengl.

project - physical simulation in graphical environments

Physical simulation in graphical environments was led by Prof. Dr. rer. nat. Bernd Fröhlich and Dipl.-Inf.(FH) Jan Hochstrate in WS 2002-2003.

The project starts with a practical introduction in the vr system avango. We implemented simulations of gravity, springs and collisions between rigid 3d bodies.

To achieve this we used vortex developed by cm-labs.

As a result we implemented a virtual forklifter game, which is featured on our project website.

project - Sicher ist Sicher

Sicher ist Sicher (something like: "safety first" in english) happens to be my first project in WS 2001-2002. The project was led by dr.rer.nat. bernd schalbe
We set up a server for storing keys based on the public key encryption method to ensure secure email transfer throughout the Bauhaus-University Weimar. We used the open source pks keyserver developed by marc horowitz.
Furthermore we wrote several howtos in using encryption programs both for windows and linux.
