    • Adaptive Tetrahedral Meshes for Brittle Fracture Simulation 

      Koschier, Dan; Lipponer, Sebastian; Bender, Jan (The Eurographics Association, 2014)
      We present a method for the adaptive simulation of brittle fracture of solid objects based on a novel reversible tetrahedral mesh refinement scheme. The refinement scheme preserves the quality of the input mesh to a large ...

    • Efficient Unsupervised Temporal Segmentation of Human Motion 

      Vögele, Anna; Krüger, Björn; Klein, Reinhard (The Eurographics Association, 2014)
      This work introduces an efficient method for fully automatic temporal segmentation of human motion sequences and similar time series. The method relies on a neighborhood graph to partition a given data sequence into distinct ...

    • Optimization Integrator for Large Time Steps 

      Gast, Theodore F.; Schroeder, Craig (The Eurographics Association, 2014)
      Practical time steps in today's state-of-the-art simulators typically rely on Newton's method to solve large systems of nonlinear equations. In practice, this works well for small time steps but is unreliable at large time ...

    • A Peridynamic Perspective on Spring-Mass Fracture 

      Levine, Joshua A.; Bargteil, Adam W.; Corsi, Christopher; Tessendorf, Jerry; Geist, Robert (The Eurographics Association, 2014)
      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 be ...

    • Position-based Elastic Rods 

      Umetani, Nobuyuki; Schmidt, Ryan; Stam, Jos (The Eurographics Association, 2014)
      We present a novel method to simulate complex bending and twisting of elastic rods. Elastic rods are commonly simulated using force based methods, such as the finite element method. These methods are accurate, but do not ...

    • Stable Orthotropic Materials 

      Li, Yijing; Barbic, Jernej (The Eurographics Association, 2014)
      Isotropic Finite Element Method (FEM) deformable object simulations are widely used in computer graphics. Several applications (wood, plants, muscles) require modeling the directional dependence of the material elastic ...

    • View-Dependent Adaptive Cloth Simulation 

      Koh, Woojong; Narain, Rahul; O'Brien, James F. (The Eurographics Association, 2014)
      This paper describes a method for view-dependent cloth simulation using dynamically adaptive mesh refinement and coarsening. Given a prescribed camera motion, the method adjusts the criteria controlling refinement to account ...
