Accelerated Simulation of Brittle Objects for Interactive Applications
Résumé
This article presents a model that aims at computing deformation and simulating fractures. To allow the use of linear elasticity in small displacements for deformation of a brittle object while still enabling any rigid motion, a rigid reference is computed using the Shape Matching method and all displacements are evaluated with respect to this reference. Fractures are handled using a stress tensor computed at each vertex of the object’s 3D mesh. Some accelerations are proposed, that allow a faster determination of fracture areas and a fast processing of new connected components.
