Research Interests
 |
 |
 |
Interactive Global Illumination How can graphics hardware (GPUs) be used to reproduce advanced visual phenomena such as soft shadows, indirect shadows, soft reflections, caustics or volumetric light in a perceptually plausible way? |
 |
 |
 |
Perceptual Graphics How are colors, shapes, or spatial layout perceived by a human observer? How can this understanding be used to predict and consequently improve the way a humans and machines interact? |
 |
 |
 |
Non-physical Graphics While physical laws define how to do render shadows or reflections "right", how to properly project a 3D scene onto a 2D image or how to deform a shape in a physical way, they sometimes are to restrictive. How can we go beyond physical laws in an appropriate way, such that a machine offers new expressive posibilities to an artist? |
 |
 |
 |
Data-driven Graphics Given the vast amount of information in user-generated content online, how can classic computer graphics techniques such as rendering or shape modelling benefit from them and for which new application will they allow? |
