M.Sc. Sebastian Weiß


I am a PhD student in the group of Rüdiger Westermann. My research focuses on the acceleration of 3D isosurface and volume rendering. For that purpose, I investigate approximation, compression and deep learning techniques for their application in computer visualization. The goal is to be able to explore large datasets in real-time which would otherwise be difficult with traditional methods.
