Welcome on the homepage of the chair "Computer Graphics Systems" of Prof. Jürgen Döllner and his team. We like to inform you about our teaching and ongoing research activities in the analysis, planning and construction of computer graphics and multimedia systems.
We investigate stereo coherence – or consistency of stereoscopic views – in non-photorealistic rendering (NPR) by example. We designed and carried out a pilot user study that compared stereoscopic animations created using two different watercolour rendering styles. The rendering styles use image-space and object-space noise respectively. A clear majority of participants preferred the object-based technique and found it more comfortable to watch than the image-space technique which suffers from the ‘shower door effect’. Based on these preliminary results, we conclude that stereo coherence is indeed a desirable property for non-photorealistic rendering techniques.
