In collaboration with Daniel Weiskopf - Development of a rendering algorithm for transparent surface in color illustrations
A method for automatically generate technical illustrations that contain opaque and non-opaque objects was developed. Traditional methods to show transparency in manual drawings were evaluated to extract a small and effective set of rules for a computer-based rendering of technical illustrations, leading to a novel view-dependent transparency model. A hardware-accelerated depth sorting algorithm in image-space which specifically meets the requirements of the transparency model was developed. In this way, realtime rendering of semi-transparent technical illustrations is achieved.

In collaboration with Daniel Weiskopf - Development of an alternative/classical method for visualizing special relativistic effects
A system was developed that can automatically generate 2+1D Minkowski diagrams. We showed how these spacetime diagrams reveal more aspects of special relativity than traditional Minkowski diagrams and can therefore further enhance the understanding of special relativity. The interactive system is based on Java3D and can be used as a widely applicable learning and teaching tool. Moreover, we adapt and extend non-photorealistic rendering techniques to improve the perceptibility of the diagrams.
