Description:


    This video demonstrates a simulation technique for animating breaking objects. By analyzing the stress tensors computed over a finite-element model, the simulation determines where cracks should initiate and in what directions they should propagate.The system dynamically re-meshes the models to accommodate these fractures. Varying the shape of the objects, the material proper-ties, and the initial conditions of the simulations, creates strikingly different effects, ranging from a wall that shatters when it is hit by a wrecking ball to a bowl that breaks in two when it is dropped on edge.
