    Band, Stefan; Gissler, Christoph; Peer, Andreas; Teschner, Matthias (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 ...

    Cattan, Grégoire; Andreev, Anton; Mendoza, Cesar; Congedo, Marco (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 ...
  • Laplacian Damping for Projective Dynamics 

    Li, Jing; Liu, Tiantian; Kavan, Ladislav (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 ...
  • Comparison of Mixed Linear Complementarity Problem Solvers for Multibody Simulations with Contact 

    Enzenhöfer, Andreas; Andrews, Sheldon; Teichmann, Marek; Kövecses, József (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 

    Banks, Matthew K.; Hazel, Andrew L.; Riley, Graham D. (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 ...
  • VRIPHYS 2018: Frontmatter 

    Andrews, Sheldon; Erleben, Kenny; Jaillet, Fabrice; Zachmann, Gabriel (Eurographics Association, 2018)
  • See-through Visualisation for Training and Assessing Unsighted Physical Examinations 

    Granados, Alejandro; Perhac, Jan; Rosby, Lucy Victoria; Lee, Yee Mun; Tan, Glenn Wei Leong; Tan, Tai Chi; Higham, Jenny; Thalmann, Nadia; Low-Beer, Naomi; Bello, Fernando (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 ...
  • Inverse Kinematic Solutions for Articulated Characters using Massively Parallel Architectures and Differential Evolutionary Algorithms 

    Kenwright, Ben (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 ...

    Gouis, Benoît Le; Marchal, Maud; Lécuyer, Anatole; Arnaldi, Bruno (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 ...

  • A Fast Linear Complementarity Problem (LCP) Solver for Separating Fluid-Solid Wall Boundary Conditions 

    Andersen, Michael; Niebe, Sarah; Erleben, Kenny (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 ...
  • Unified Simulation of Rigid and Flexible Bodies Using Position Based Dynamics 

    Frâncu, Mihai; Moldoveanu, Florica (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 ...
  • Approximate Air-Fluid Interactions for SPH 

    Gissler, Christoph; Band, Stefan; Peer, Andreas; Ihmsen, Markus; Teschner, Matthias (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 

    Band, Stefan; Gissler, Christoph; Teschner, Matthias (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 ...
