Working with Volumetric Meshes in a Game Engine: a Unity Prototype
(The Eurographics Association, 2020)
Volumetric meshes are useful assets in many different research and application fields, like physical simulations, FEM or IGA. In the last decade, the Computer Graphics community dedicated a lot of effort in studying and ...
Generación de fenómenos naturales mediante la simulación realista de sólidos deformables en Bifrost
(The Eurographics Association, 2021)
La simulación de fluidos y sólidos deformables ha sido ampliamente estudiada en Informática Gráfica. Existen diferentes soluciones que posibilitan una simulación cada vez más realista en entornos del mundo real. Para ello, ...
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 ...
Frequency-Aware Reconstruction of Fluid Simulations with Generative Networks
(The Eurographics Association, 2020)
Convolutional neural networks were recently employed to fully reconstruct fluid simulation data from a set of reduced parameters. However, since (de-)convolutions traditionally trained with supervised l1-loss functions do ...
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 ...
Monocular 3D Fluid Volume Reconstruction Based on a Multilayer External Force Guiding Model
(The Eurographics Association, 2020)
In this paper, we present a monocular 3D fluid volume reconstruction technique that can alleviate challenging parameter tuning while vividly reproducing the inflow and outflow of the video scene. To reconstruct the geometric ...
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. ...
Neural Smoke Stylization with Color Transfer
(The Eurographics Association, 2020)
Artistically controlling fluid simulations requires a large amount of manual work by an artist. The recently presented transportbased neural style transfer approach simplifies workflows as it transfers the style of arbitrary ...
Fast Corotated Elastic SPH Solids with Implicit Zero-Energy Mode Control
(ACM, 2021)
We develop a new operator splitting formulation for the simulation of corotated linearly elastic solids with Smoothed Particle Hydrodynamics (SPH). Based on the technique of Kugelstadt et al. [2018] originally developed ...
