    Fast dynamic fracture of brittle objects in 3D



    Fracture simulation is an important aspect of computer games as it enhances interactivity and realism. Due to the high computational cost, most computer games do not simulate accurate fractures. The ideal fracture model for computer games should be fast and respond to user actions somewhat realistically. Most of the existing fracture modeling techniques are designed for non real-time computer animation (e.g. [O’Brien and Hodgins August 1999; Smith et al. 2001]) and are not only computationally expensive but also more realistic than necessary for computer games. Our algorithm uses a multi-stage dynamic refinement technique to reduce the necessary number of tetrahedral meshes for realistic results, thus reducing the computational cost. This work is an extension of the work of Oda et al. [August 2005] to 3D.
