About
Since I'm always busy somehow or not in the mood to create a fancy page it's pretty puristic here... but you'll find lots of content...
I am a Master of Computer Science (Dipl.-Ing.) and currently working at the Unit for Strength of Materials and Structural Analysis at the Faculty of Civil Engineering, University of Innsbruck and are involved in the airborne hydromapping project and spinoff company AHM. I sometimes tend to work here at Clockstone Studio as 3D/2D graphic artist, level designer, script programmer, etc ... ... usually on computer games.
While, doing my second masters in Civil Engineering here in Innsbruck Austria.
While, collaborating with the Center for Computation and Technology (in USA Louisiana) working on scientific visualization in vish.
While, playing the bassoon here and here and everywhere else where they let me play. :)
Here are some links to graphic projects I've been working on in the past. At least those that I created some documentation for ... ;)
| Greed (2009) | 'The Black Border' a 3D hack n slay game, out on the international market with an average rating of 60%, check out our company: Clockstone Software GmbH. |
| Avencast (2004-2007) | 'The Rise of the Mage' a 3D action roleplaying game, out on the international market with an average rating of 75%, check out our company: Clockstone Software GmbH. |

Development of a Plug-In to Visualise Effects Caused by the Bending of Light by Masses (Rendering Balckholes in Maya), Bachelor Thesis 1 (2005),
Computer Science at the department for Computational Logic at the University Innsbruck, additional cooperation with Living Liquid Software GmbH
Example: Animation of two blackholes
Note that this was my first approach. I have worked on a mental ray port and also found a different approach that integrates much better with all the standard features, such as volume rendering and multiple black holes.
Introduction to HDF5 and F5, Bachelor Thesis 2 (2007/08),
Describing the data file format F5 created by Werner Benger
Computer Science at the department Infmath at the University Innsbruck collaborating with the Center for Computation and Technology (CCT).) at the Lousiana State University (LSU).
Essay on Theory of Science, this is a philosophical paper written together with the mathematician Gunther Bergauer. If you even wanted to know what 'science' is or how 'scientific work' could be rated you can read our theory. But be warned, this is destilled 30 pages of 2 years thoughts and discussions. It's also meant to be fun and starts from the veeeeery beginning ... ;)
Since the many layers of the work are really hard to translate it is available in german only, sorry! If you're interested in philosophy you'll definitely enjoy and it'll make you smile. :) ...
'... Die Autoren sind Menschen. Wir wollen Menschen vorerst nicht definieren, uns reicht es, dass sie eindimensional sind. ...'
Contributed realtime 3D visualization of streamlines, pathlines and geodesics in huge, numerical, curvilinear multiblock or AMR data sets using vish at the Center for Computation and Technology (CCT) at the Lousiana State University (LSU) at the group for Scientific Visualization, by writing a Master Thesis at the department Infmath at the University Innsbruck.
Have a look at the vish gallery.
Currently working on the Bachlor Thesis for civil engineering at the Institute for Steel Constructions at the University Innsbruck ... doing too many pages of good old hand made calculations and writing a software tool for cross-section classification.
