MLS Pressure Extrapolation for the Boundary Handling in Divergence-Free SPH
(The Eurographics Association, 2018)We propose a novel method to predict pressure values at boundary particles in incompressible divergence-free SPH simulations (DFSPH). Our approach employs Moving Least Squares (MLS) to predict the pressure at boundary ... -
Real-Time Virtual Pipes Simulation and Modeling for Small-Scale Shallow Water
(The Eurographics Association, 2018)We propose an approach for real-time shallow water simulation, building upon the virtual pipes model with multi-layered heightmaps. Our approach introduces the use of extended pipes which resolve flow through fully-flooded ... -
Fast Quadrangular Mass-Spring Systems using Red-Black Ordering
(The Eurographics Association, 2018)We introduce a practical iterative solver for mass-spring systems which can be trivially mapped to massively parallel architectures, in particular GPUs.We employ our solver for the interactive animation of virtual cloth ... -
Laplacian Damping for Projective Dynamics
(The Eurographics Association, 2018)Damping is an important ingredient in physics-based simulation of deformable objects. Recent work introduced new fast simulation methods such as Position Based Dynamics and Projective Dynamics. Explicit velocity damping ... -
The Impact of Passive Head-Mounted Virtual Reality Devices on the Quality of EEG Signals
(The Eurographics Association, 2018)Thanks to the low price, the use of a head-mounted device (HMD) equipped with a smartphone is currently a common set-up for virtual reality (VR). Brain-computer interface (BCI) based on electroencephalography (EEG) is a ... -
Comparison of Mixed Linear Complementarity Problem Solvers for Multibody Simulations with Contact
(The Eurographics Association, 2018)The trade-off between accuracy and computational performance is one of the central conflicts in real-time multibody simulations, much of which can be attributed to the method used to solve the constrained multibody equations. ... -
Quantitative Validation of Physically Based Deformable Models in Computer Graphics
(The Eurographics Association, 2018)This paper presents a novel software framework for quantitative validation of physically-based deformable models in computer graphics. In the majority of previous studies, validation is qualitative (through visual ... -

See-through Visualisation for Training and Assessing Unsighted Physical Examinations
(The Eurographics Association, 2017)Objective: Motivated by the limitations of being unable to provide feedback and adequately assess technical skills whilst training unsighted physical examinations, such as Digital Rectal Examinations (DRE), we present a ... -
Elasticity-based Clustering for Haptic Interaction with Heterogeneous Deformable Objects
(The Eurographics Association, 2017)Physically-based simulation of heterogeneous objects remains computationally-demanding for many applications, especially when involving haptic interaction with virtual environments. In this paper, we introduce a novel ... -
Kernel Projection of Latent Structures Regression for Facial Animation Retargeting
(The Eurographics Association, 2017)Inspired by kernel methods that have been used extensively in achieving efficient facial animation retargeting, this paper presents a solution to retargeting facial animation in virtual character's face model based on the ... -
Inverse Kinematic Solutions for Articulated Characters using Massively Parallel Architectures and Differential Evolutionary Algorithms
(The Eurographics Association, 2017)This paper presents a Differential Evolutionary (DE) algorithm for solving multi-objective kinematic problems (e.g., end-effector locations, centre-of-mass and comfort factors). Inverse kinematic problems in the context ... -
Unified Simulation of Rigid and Flexible Bodies Using Position Based Dynamics
(The Eurographics Association, 2017)In this paper we present a new position based approach for simulating rigid and flexible bodies with two-way coupling. This is achieved by expressing all the dynamics as constraints and running them in the same solver. Our ... -
A Fast Linear Complementarity Problem (LCP) Solver for Separating Fluid-Solid Wall Boundary Conditions
(The Eurographics Association, 2017)We address the task of computing solutions for a separating fluid-solid wall boundary condition model. We present an embarrassingly parallel, easy to implement, fluid LCP solver.We are able to use greater domain sizes than ... -
Approximate Air-Fluid Interactions for SPH
(The Eurographics Association, 2017)Computing the forces acting from a surrounding air phase onto an SPH free-surface fluid is challenging. For full multiphase simulations the computational overhead is significant and stability issues due to the high density ... -
Moving Least Squares Boundaries for SPH Fluids
(The Eurographics Association, 2017)The paper shows that the SPH boundary handling of Akinci et al. [AIA 12] suffers from perceivable issues in planar regions due to deviations in the computed boundary normals and due to erroneous oscillations in the distance ... -
Implicit Mesh Generation using Volumetric Subdivision
(The Eurographics Association, 2017)In this paper, we present a novel approach for a tighter integration of 3D modeling and physically-based simulation. Instead of modeling 3D objects as surface models, we use a volumetric subdivision representation. Volumetric ... -
Real-time Landscape-size Convective Clouds Simulation and Rendering
(The Eurographics Association, 2017)This paper presents an efficient, physics-based procedural model for the real-time animation and visualization of cumulus clouds at landscape size. We couple a coarse Lagrangian model of air parcels with a procedural ... -

Area Preserving Strain Limiting
(The Eurographics Association, 2015)In this paper we present a novel fast strain-limiting method that allows cloth to preserve its surface area efficiently. By preserving triangle area rather than edge length as other approaches do, this method does not ...
