Subspace Fluid Re-Simulation

Theodore Kim, John Delaney We present a new subspace integration method that is capable of efficiently adding and subtracting dynamics from an existing high-resolution fluid simulation. We show how to analyze the results of an existing high-resolution simulation, discover an efficient reduced approximation, and use it to quickly “re-simulate” novel variations of the original dynamics.

Embedded Thin Shells for Wrinkle Simulation

Olivier Remillard, Paul G. Kry We present a new technique for simulating high resolution surface wrinkling deformations of composite objects consisting of a soft interior and a harder skin. We combine high resolution thin shells with coarse finite element lattices and define frequency based constraints that allow the formation of wrinkles with properties matching those […]

Efficient GPU data structures and methods to solve sparse linear systems in dynamics applications

Daniel Weber, Jan Bender, Markus Schnoes, Andre Stork and Dieter Fellner We present GPU data structures and algorithms to efficiently solve sparse linear systems which are typically required in simulations of multibody systems and deformable bodies. Thereby, we introduce an efficient sparse matrix data structure that can handle arbitrary sparsity patterns and outperforms current state-of-the-art […]

Synthetic Controllable Turbulence Using Robust Second Vorticity Confinement

Shengfeng He, Rynson W. H. Lau Capturing fine details of turbulence on a coarse grid is one of the main tasks in real-time fluid simulation. Existing methods for doing this have various limitations. In this paper, we propose a new turbulence method that uses a refined Second Vorticity Confinement method, referred to as Robust Second […]

Super Space Clothoids

Romain Casati, Florence Bertails-Descoubes Thin elastic filaments in real world such as vine tendrils, hair ringlets or curled ribbons often depict a very smooth, curved shape that low-order rod models — e.g., segment-based rods — fail to reproduce accurately and compactly. In this paper, we push forward the investigation of high-order models for thin, inextensible […]

Adaptive Fracture Simulation of Multi-Layered Thin Plates

Oleksiy Busaryev, Tamal K. Dey, Huamin Wang The fractures of thin plates often exhibit complex physical behaviors in the real world. In particular, fractures caused by tearing are different from fractures caused by in-plane motions. In this paper, we study how to make thin-plate fracture animations more realistic from three perspectives. We propose a stress […]

Modeling Friction and Air Effects between Cloth and Deformable Bodies

Zhili Chen, Renguo Feng, Huamin Wang Real-world cloth exhibits complex behaviors when it contacts deformable bodies. In this paper, we study how to improve the simulation of cloth-body interactions from three perspectives: collision, friction, and air pressure. We propose an efficient and robust algorithm to detect the collisions between cloth and deformable bodies, using the […]

Highly Adaptive Liquid Simulations on Tetrahedral Meshes

Ryoichi Ando, Nils Thürey and Chris Wojtan We introduce a new method for efficiently simulating liquid with extreme amounts of spatial adaptivity. Our method combines several key components to drastically speed up the simulation of large-scale fluid phenomena: We leverage an alternative Eulerian tetrahedral mesh discretization to significantly reduce the complexity of the pressure solve while […]
