An approach to enrich skeleton-driven animations with physically-based secondary deformation in real time is described. To achieve this goal, the technique described employs a surface-based deformable model that can interactively emulate the dynamics of both low- and high-frequency volumetric effects....http://www.google.de/patents/US8144155?utm_source=gb-gplus-sharePatent US8144155 - Example-based motion detail enrichment in real-time
