Joshua A. Levine, Adam W. Bargteil, Christopher Corsi, Jerry Tessendorf, Robert Geist  The application of spring-mass systems to the animation of brittle fracture is revisited. The motivation arises from the recent popularity of peridynamics in the computational physics community. Peridynamic systems can … Continue reading →

Saket Patkar, Mridul Aanjaneya, Aric Bartle, Minjae Lee, Ronald Fedkiw We present a novel method for the efficient denting and bending of rigid bodies without the need for expensive finite element simulations. Denting is achieved by deforming the triangulated surface of … Continue reading →

Zhili Chen, Miaojun Yao, Renguo Feng, Huamin Wang Physically based animation of detailed fracture effects is not only computationally expensive, but also difficult to implement due to numerical instability. In this paper, we propose a physics-inspired approach to enrich low-resolution fracture animation by … Continue reading →

Huamin Wang Numerical errors and rounding errors in continuous collision detection (CCD) can easily cause collision detection failures if they are not handled properly. A simple and effective approach is to use error tolerances, as shown in many existing CCD … Continue reading →

Ye Fan, Joshua Litven, Dinesh Pai We introduce a new framework for simulating the dynamics of musculoskeletal systems, with volumetric muscles in close contact and a novel data-driven muscle activation model. Muscles are simulated using an Eulerian-on-Lagrangian discretization that handles volume preservation, large deformation, … Continue reading →

Florian Reichl,  Matthäus G. Chajdas,  Jens Schneider, and  Rüdiger Westermann We describe the design of an interactive rendering system for particle-based fluid simulations comprising hundreds of millions of particles per time step. We present a novel binary voxel representation for particle positions in … Continue reading →
