Efficient Unified Stokes using a Polynomial Reduced Fluid Model
(The Eurographics Association, 2020)
Unsteady Stokes solvers, coupling stress and pressure forces, are a key component of accurate free surface simulators for highly viscous fluids. Because of the simultaneous application of stress and pressure terms, this ...
Interactive Wood Fracture
(The Eurographics Association, 2020)
Abstract We propose a new approach for the simulation of wood as anisotropic material that takes its inherent fiber structure into account. Our approach is based on the Position-based Dynamics framework. We use the Shape ...
Fast Eulerian Fluid Simulation In Games Using Poisson Filters
(The Eurographics Association, 2020)
We present separable Poisson filters to accelerate the projection step in Eulerian fluid simulation. These filters are analytically computed offline and are easy to integrate into any fluid algorithm with a Poisson pressure ...
Contact and Human Dynamics from Monocular Video
(The Eurographics Association, 2020)
Existing methods for human motion from video predict 2D and 3D poses that are approximately accurate, but contain visible errors that violate physical constraints, such as feet penetrating the ground and bodies leaning at ...
WeightShift: Accelerating Animation at Framestore with Physics
(The Eurographics Association, 2020)
Framestore and WeightShift created a full-body physics simulation to deliver art-directed shots in highly dynamic scenarios in several days instead of several weeks. Our technique combines ragdoll simulation and keyframe ...
ZooBuilder: 2D and 3D Pose Estimation for Quadrupeds Using Synthetic Data
(The Eurographics Association, 2020)
This work introduces a novel strategy for generating synthetic training data for 2D and 3D pose estimation of animals using keyframe animations. With the objective to automate the process of creating animations for wildlife, ...
Negative Jacobian Free Simulations Using Principal Stretches
(The Eurographics Association, 2020)
Finite element (FE) simulations are prone to encountering negative Jacobians during the solving process. If nothing is done, the simulation can be brought to a halt, result in inverted elements or have undetermined behavior. ...
Wind Erosion: Shape Modifications by Interactive Particle-based Erosion and Deposition
(The Eurographics Association, 2020)
We present a novel user-assisted method for physics-inspired modeling of geomorphological features on polygonal meshes using material erosion and deposition as the driving mechanisms. Polygonal meshes defining an input ...
