Xuchen Han, Theodore Gast, Qi Guo, Stephanie Wang, Chenfanfu Jiang, Joseph Teran We present a new hybrid Lagrangian Material Point Method for simulating elastic objects like hair, rubber,and soft tissues that utilizes a Lagrangian mesh for internal force computation and … Continue reading →

Miles Macklin, Kier Storey, Michelle Lu, Pierre Terdiman, Nuttapong Chentanez, Stefan Jeschke, Matthias Müller In this paper we re-examine the idea that implicit integrators with large time steps offer the best stability/performance trade-off for stiff systems. We make the surprising … Continue reading →

Rahul Narain, Jonas Zehnder, Bernhard Thomaszewski Zehnder et al. [2018] recently introduced an advection-reflection method for fluid simulation that dramatically reduces artificial dissipation. We establish a connection between their method and the implicit midpoint time integration scheme, and present a … Continue reading →

Jing Li, Tiantian Liu, Ladislav Kavan We propose a fast and robust solver to simulate continuum-based deformable models with constraints, in particular, rigid-body and joint constraints useful for soft articulated characters. Our method embeds degrees of freedom of both articulated … Continue reading →

Daniel Holden, Bang Chi Duong, Sayantan Datta, Derek Nowrouzezahrai Data-driven methods for physical simulation are an attractive option for interactive applications due to their ability to trade precomputation and memory footprint in exchange for improved runtime performance. Yet, existing data-driven … Continue reading →

Peter Kadlecek, Ladislav Kavan The human face is an anatomical system exhibiting heterogenous and anisotropic mechanical behavior. This leads to complex deformations even in a neutral facial expression due to external forces such as gravity. We start by building a … Continue reading →

Yu Ju (Edwin) Chen, David I.W. Levin, Danny Kaufman, Uri Ascher, Dinesh K. Pai Elastodynamic system simulation is a key procedure in computer graphics and robotics applications. To enable these simulations, the governing differential system is discretized in space (employing … Continue reading →

Jumyung Chang, Fang Da, Eitan Grinspun, Christopher Batty We present a unified method to simulate deformable elastic bodies consisting of mixed-dimensional components represented with potentially non-manifold simplicial meshes. Building on well-known simplicial rod, shell, and solid models for elastic continua, … Continue reading →

Minjae Lee, David Hyde, Kevin Li, Ronald Fedkiw We propose a novel volume conserving framework for character-water interaction, using a novel volume-of-fluid solver on a skinned tetrahedral mesh, enabling the high degree of the spatial adaptivity in order to capture … Continue reading →

Marco Romeo, Carlos Monteagudo, Daniel Sánchez‐Quirós Recent research on muscle and fascia simulation for visual effects relies on numerical methods such as the finite element method or finite volume method. These approaches produce realistic results, but require high computational time … Continue reading →
