Adaptive Resolution for Topology Modifications in Physically-based Animation

This paper shows the interest of basing a mechanical mesh upon an efficient topological model in order to give any simulation the ability to refine this mesh locally and apply topological modifications such as cutting, tear and matter destruction. Refinement and modifications can indeed be combined in order to get a more precise result. The powerful combinatorial map model provides the mathematical background which ensures that the quasi-manifold property is guaranteed for the mesh after any topological modification. The obtained results offer the versatility and time efficiency that are expected in applications such as surgical simulation. keywords:Physically-based animation, Adaptive/hierarchical models, Generalised maps, Topological modifications, surgical simulation.
