Animation and Modeling of Brittle Fracture
Realistic animation of fracture is a difficult one like many other natural phenomena. In computer graphics history, there have been some approaches to this specific problem. In this talk, we will go over these techniques and specifically focus on an approach realized by a system that combines rigid body simulation methods with a constraint-based model to animate fracturing of arbitrary polyhedral shaped objects under impact. For this system, the objects are represented as sets of masses, where pairs of adjacent masses are connected via a distance-preserving linear constraint. Lagrange multipliers are used to compute the forces exerted by those constraints, where these forces determine how and where the object will break. Additionally, we will talk about methods for dealing with the well-defined uniformity in initial object models, which makes the generated animations unrealistic.
