Marco Fratarcangeli, Fabio Pellacini We introduce a practical partitioning technique designed for parallelizing Position Based Dynamics, and exploit- ing the ubiquitous multi-core processors present in current commodity GPUs. The input is a set of particles whose dynamics is influenced by spatial constraints. In the initialization phase, we build a graph in which each node corresponds […]

Hongyi Xu, Yijing Li, Yong Chen, Jernej Barbic We demonstrate an interactive method to create heterogeneous continuous deformable materials on complex three-dimensional meshes. The user specifies displacements and internal elastic forces at a chosen set of mesh vertices. Our system then rapidly solves an optimization problem to compute a corresponding heterogeneous spatial distribution of material properties, using the Finite […]

Adam W. Bargteil, Ben Jones In this paper, we advocate explicit symplectic Euler integration and strain limiting in a shape matching simulation framework. The resulting approach resembles not only previous work on shape matching and strain limiting, but also the recently popular position-based dynamics.However, unlike this previous work, our approach reduces to explicit integration under small strains, […]

Sören Pirk, Till Niese, Torsten Hädrich, Bedrich Benes, Oliver Deussen We present a novel method for combining developmental tree models with turbulent wind fields. The tree geometry is created from internal growth functions of the developmental model and its response to external stress is induced by a physically-plausible wind field that is simulated by Smoothed […]

Adam W. Bargteil, Elaine Cohen In this paper, we investigate the use of quadratic finite elements for graphical animation of deformable bodies. We consider both integrating quadratic elements with conventional linear elements to achieve a computationally efficient adaptive-degree simulation framework as well as wholly quadratic elements for the simulation of non-linear rest shapes. In both […]
