Previous methods mainly consider bulk fractures. However, in many situations, small fractured pieces and debris are visually important. Our framework takes a hybrid approach that integrates both tetrahedron-based finite element and particlebased meshfree methods. The simulation starts with a tetrahedral mesh. When the damage of elements reaches a damage failure threshold, the associated nodes are converted into mass-based particles. Molecular dynamics is used to model particle motion and interaction with other particles and the remaining elements. In rendering, we propose an algorithm of dynamically extracting a polygonal boundary surface for the damaged elements and particles. Our framework is simple, accurate, and efficient. It avoids the remeshing and stability problems of pure mesh-based techniques and pure meshfree methods and offers high visual realism.Categories and Subject Descriptors (according to ACM CCS): I.3.5 [Computer Graphics]: Computational Geometry and Object Modeling-Physics based modeling; I.3.7 [Computer Graphics]: Three-Dimensional Graphics and Realism-Animation
