Dr.-Ing. Dominik Wodniok

Graphics Engineer

I work as a Senior Graphics Engineer at Gritworld GmbH Frankfurt. I was a PhD Student in the Graphics, Capture, and Massively Parallel Computing Group of Michael Goesele at TU Darmstadt where I also was a Research Associate. I worked on computer graphics problems with a focus on ray tracing acceleration structures.

This site provides information on my reasearch and public code. Feel free to contact me if you have any questions.

Research Interests
