Voronoi Filters for Simulation Enrichment
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
The simulation of complex deformation problems often requires enrichment techniques that introduce local high-resolution detail on a generally coarse discretization. The use cases include spatial or temporal refinement of ...
Efficient and Stable Simulation of Inextensible Cosserat Rods by a Compact Representation
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
Piecewise linear inextensible Cosserat rods are usually represented by Cartesian coordinates of vertices and quaternions on the segments. Such representations use excessive degrees of freedom (DOFs), and need many additional ...
Tiled Characteristic Maps for Tracking Detailed Liquid Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
We introduce tiled characteristic maps for level set method that accurately preserves both thin sheets and sharp edges over a long period of time. Instead of resorting to high-order differential schemes, we utilize the ...
Learning Physics with a Hierarchical Graph Network
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
We propose a hierarchical graph for learning physics and a novel way to handle obstacles. The finest level of the graph consist of the particles itself. Coarser levels consist of the cells of sparse grids with successively ...
A Second-Order Explicit Pressure Projection Method for Eulerian Fluid Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
In this paper, we propose a novel second-order explicit midpoint method to address the issue of energy loss and vorticity dissipation in Eulerian fluid simulation. The basic idea is to explicitly compute the pressure ...
A-ULMPM: An Adaptively Updated Lagrangian Material Point Method for Efficient Physics Simulation without Numerical Fracture
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
We present an adaptively updated Lagrangian Material Point Method (A-ULMPM) to alleviate non-physical artifacts, such as the cell-crossing instability and numerical fracture, that plague state-of-the-art Eulerian formulations ...
Neural3Points: Learning to Generate Physically Realistic Full-body Motion for Virtual Reality Users
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
Animating an avatar that reflects a user's action in the VR world enables natural interactions with the virtual environment. It has the potential to allow remote users to communicate and collaborate in a way as if they met ...
Fast Numerical Coarsening with Local Factorizations
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
Numerical coarsening methods offer an attractive methodology for fast simulation of objects with high-resolution heterogeneity. However, they rely heavily on preprocessing, and are not suitable when objects undergo dynamic ...
Computational Design of Kinesthetic Garments
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
Kinesthetic garments provide physical feedback on body posture and motion through tailored distributions of reinforced material. Their ability to selectively stiffen a garment's response to specific motions makes them ...
N-Cloth: Predicting 3D Cloth Deformation with Mesh-Based Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
We present a novel mesh-based learning approach (N-Cloth) for plausible 3D cloth deformation prediction. Our approach is general and can handle cloth or obstacles represented by triangle meshes with arbitrary topologies.We ...
