The research at GRIS tackles various topics of 3D Animation and Visualization, including GPU-based fluid animation and full visualization techniques for complex 3D voxel data. 3D animation is wide-ranged and complex topic and can include physical and morphological models to create realistic visualizations. 3D visualizations are needed in nearly all 3D applications. Still, in many cases the usual visualizations are not able to show all special aspects of the data. Also, a preceding transformation to a polygon mesh is often needed, further blurring the analysis of the underlying data. Therefore, numerous applications demand for the development of specialized informative visualizations directly showing all aspects of the real data.
