Expertise
The computer graphics group at University of Bremen carries out fundamental and applied research in visual computing. Visual computing comprises image generation, including modeling and simulation, as well as image understanding, based on diverse disciplines such as mathematics, computer science, and others.

Our areas of expertise are in diverse areas of visual computing such as geometric algorithms, acceleration data structures for geometric queries (e.g., proximity and ray queries), collision detection and handling, point clouds, interaction in virtual environments, and marker-less articulated object tracking (in particular, hand tracking). We put particular emphasis on comprehensive analysis, task-specific mathematical modeling, design of very efficient algorithms, robust and high-speed implementations, and thorough evaluation of our solutions.

Application areas we are interested in are virtual prototyping, computational medicine, robotics, entertainment, manufacturing industries, and others.
