    • 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 ...

    • An Adaptive Virtual Node Algorithm with Robust Mesh Cutting 

      Wang, Yuting; Jiang, Chenfanfu; Schroeder, Craig; Teran, Joseph (The Eurographics Association, 2014)
      We present a novel virtual node algorithm (VNA) for changing tetrahedron mesh topology to represent arbitrary cutting triangulated surfaces. Our approach addresses a number of shortcomings in the original VNA of [MBF04]. ...

    • Fast Grid-Based Nonlinear Elasticity for 2D Deformations 

      Setaluri, Rajsekhar; Wang, Yu; Mitchell, Nathan; Kavan, Ladislav; Sifakis, Eftychios (The Eurographics Association, 2014)
      We present a deformation technique that constructs 2D warps by using spline curves to specify the starting and target shapes of selected key contours. We generate a two-dimensional deformation map from these contours by ...

    • 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 ...

    • Steklov-Poincaré Skinning 

      Gao, Ming; Mitchell, Nathan; Sifakis, Eftychios (The Eurographics Association, 2014)
      We introduce a novel and efficient simulation technique for generating physics-based skinning animations of skeleton-driven characters with full support for collision handling. Although physics-based approaches may use a ...

    • Strain Based Dynamics 

      Müller, Matthias; Chentanez, Nuttapong; Kim, Tae-Yong; Macklin, Miles (The Eurographics Association, 2014)
      We propose a new set of constraints within the Position Based Dynamics (PBD) framework that allow the control of strain in directions that are independent of the edge directions of the simulation mesh. Instead of constraining ...

    • 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 ...
