Oscar Argudo, Eric Galin, Adrien Peytavie, Axel Paris, Eric Guerin Glaciers are some of the most visually arresting and scenic elements of cold regions and high mountain landscapes. Although snow-covered terrains have previously received attention in computer graphics, simulating the … Continue reading →

Rafael Nakanishi, Filipe Nascimento, Rafael Campos, Paulo Pagliosa, Afonso Paiva We introduce a novel liquid simulation approach that combines a spatially adaptive pressure projection solver with the Particle-in-Cell (PIC) method. The solver relies on a generalized version of the Finite … Continue reading →

Tao Du, Kui Wu, Andrew Spielberg, Wojciech Matusik, Bo Zhu, Eftychios Sifakis We present a method for performance-driven optimization of fluidic devices. In our approach, engineers provide a high-level specification of a device using parametric surfaces for the fluid-solid boundaries. … Continue reading →

Jiayi Eris Zhang, Seungbae Bang, David IW Levin, Alec Jacobson We present a novel approach to enrich arbitrary rig animations with elastodynamic secondary effects. Unlike previous methods which pit rig displacements and physical forces as adversaries against each other, we … Continue reading →

Monolith: A Monolithic Pressure-Viscosity-Contact Solver for Strong Two-Way Rigid-Rigid Rigid-Fluid Coupling A Novel Discretization and Numerical Solver for Non-Fourier Diffusion Complementary Dynamics Functional Optimization of Fluid Devices with Differentiable Stokes Flow Surface-Only Ferrofluids RBF Liquids: An Adaptive PIC Solve Using … Continue reading →

Tao Xue, Haozhe Su, Chengguizi Han, Chenfanfu Jiang, Mridul Aanjaneya We introduce the C-F diffusion model [Anderson and Tamma 2006; Xue et al.2018] to computer graphics for diffusion-driven problems that has several attractive properties: (a) it fundamentally explains diffusion from … Continue reading →

Yu Fang*, Ziyin Qu*, Minchen Li, Xinxin Zhang, Yixin Zhu, Mridul Aanjaneya, Chenfanfu Jiang We propose a novel scheme for simulating two-way coupled interactions between nonlinear elastic solids and incompressible fluids. The key ingredient of this approach is a ghost … Continue reading →

Doug L. James Physics-based simulations of deforming tetrahedral meshes are widely used to animate detailed embedded geometry. Unfortunately most practitioners still use linear interpolation (or other low-order schemes) on tetrahedra, which can produce undesirable visual artifacts, e.g., faceting and shading … Continue reading →

Joshuah Wolper, Yunuo Chen, Minchen Li, Yu Fang, Ziyin Qu, Jiecong Lu, Meggie Cheng, Chenfanfu Jiang Dynamic fracture surrounds us in our day-to-day lives, but animating this phenomenon is notoriously difficult and only further complicated by anisotropic materials—those with underlying … Continue reading →

Jan Bender, Tassilo Kugelstadt, Marcel Weiler, Dan Koschier In this paper, we present a novel method for the robust handling of static and dynamic rigid boundaries in Smoothed Particle Hydrodynamics (SPH) simulations. We build upon the ideas of the density … Continue reading →
