For me, solving complex mathematical equations and writing delicate computer programs can be both challenging and rewarding, especially if the result is a beautiful image being valued by non-technicians.

What I am enthusiastic about

Writing optimized graphics programs using C++, CUDA, OpenCL, OpenGL and other suitable technologies. While being passionate about global illumination and light transport algorithms, I am also interested in related areas, e.g. image processing and computational geometry. I am getting more interested in human perception of images helping to improve light transport algorithms.

"When I see great images, e.g. in nature or photography, it feels like I want to render this."



My Goal - Or Dream

Writing an elegant tracing engine to visually convincingly render human faces (incl. hair), phosphorescence, fluorescence, heterogeneous media and possibly other physical phenomena in a dynamic scene in real time, or at least interactively. And along the way developing tools (requiring simulation of physical processes) helping and speeding up the art workflow for creating complex scenes.

"I don't give up that easily, this goal, and I don't stop searching."



Recent Activities & Achievements

Feb. 12, 2015: Won the 2nd Rendering Competition Prize in the course "Computer Graphics" at the Saarland University Germany during my master in Visual Computing. I implemented a path tracer with russian roulette proportional to luminance of path throughput, combined with multiple importance sampling of the BRDF and area light sources, as well as stratified image plane sampling with Mitchell filtering.

"This brings me a tiny little step nearer to my goal."


Dec. 16, 2014: Presentation of my Bachelor thesis "Incremental Light Propagation Volumes in CAVE-like Installations" at the Open Lab Day at the Leibniz Supercomputing Centre in Munich, Germany. See Program

"Gave me a lot of experiences with CUDA, plain optimized OpenGL.
 Sometimes it was just work, but most of the time it felt more like fun.
 Thanks for giving this opportunity."
