In the animation of deformable objects, collision detection is crucial for the performance. Contrary to volumetric bodies, the accuracy requirements for the collision treatment of textiles are particularly strict because any overlapping is visible. Therefore, we apply methods specifically designed for deformable surfaces that speed up the collision(More)
We present an alternative approach to standard geometric shape editing using physically-based simulation. With our technique, the user can deform complex objects in real-time. The basis of our method is formed by a fast and accurate finite element implementation of an elasto-plastic material model, specifically designed for interactive shape manipulation.(More)
We present a learning-based method for the estimation of skill levels from sequences of complex movements in sports. Our method is based on a hierarchical algorithm for computing spatio-temporal correspondence between sequences of complex body movements. The algorithm establishes correspondence at two levels: whole action sequences and individual movement(More)
We present several methods for the generation of complex human motion trajectories by linear combination of prototypical example trajectories with well-defined styles. These methods decompose longer trajectories automatically into movement primitives by robust matching with stored templates. To synthesize movement primitives with new style properties,(More)
In the animation of deformable objects, collision detection and response are crucial for the performance. Furthermore , a physically correct cloth simulation requires robust collision avoidance, since any overlapping is visible and often results in expensive correction procedures. Much progress has been achieved in improving the numerical solution , and(More)
We present a new method to simulate deformable volumet-ric objects interactively using finite elements. With quadratic basis functions and a non-linear strain tensor, we are able to model realistic local compression as well as large global deformation. The construction of the differential equations is described in detail including the Jacobian matrix(More)
Dissertation der Fakultät für Informations-und Kognitionswissenschaften der Eberhard-Karls-Universität Tübingen zur Erlangung des Grades eines Doktors der Naturwissenschaften Abstract The generation and visualisation of moving virtual objects is of particular concern in computer graphics. Most notably, the animation of deforming models is complex depending(More)
