    • Local Poisson SPH For Viscous Incompressible Fluids 

      He, Xiaowei; Liu, Ning; Li, Sheng; Wang, Hongan; Wang, Guoping (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Enforcing fluid incompressibility is one of the time‐consuming aspects in SPH. In this paper, we present a local Poisson SPH (LPSPH) method to solve incompressibility for particle based fluid simulation. Considering the ...

      Fujieda, Shin; Yoshimura, Atsushi; Harada, Takahiro (The Eurographics Association, 2023)
      A multi-layer perceptron (MLP) is a type of neural networks which has a long history of research and has been studied actively recently in computer vision and graphics fields. One of the well-known problems of an MLP is ...

    • Local Quasi-Monte Carlo Exploration 

      Tessari, Lorenzo; Hanika, Johannes; Dachsbacher, Carsten (The Eurographics Association, 2017)
      In physically-based image synthesis, the path space of light transport paths is usually explored by stochastic sampling. The two main families of algorithms are Monte Carlo/quasi-Monte Carlo sampling and Markov chain Monte ...

    • Local Remote Photoplethysmography Signal Analysis for Application in Presentation Attack Detection 

      Kossack, Benjamin; Wisotzky, Eric L.; Hilsmann, Anna; Eisert, Peter (The Eurographics Association, 2019)
      This paper presents a method to analyze and visualize the local blood flow through human skin tissue within the face and neck. The method is based on the local signal characteristics and extracts and analyses the local ...

    • Local Scale Adaptation to Hand Shape Model for Accurate and Robust Hand Tracking 

      Kalshetti, Pratik; Chaudhuri, Parag (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      The accuracy of hand tracking algorithms depends on how closely the geometry of the mesh model resembles the user's hand shape. Most existing methods rely on a learned shape space model; however, this fails to generalize ...

    • Local Shading Coherence Extraction for SIMD-Efficient Path Tracing on CPUs 

      Áfra, Attila T.; Benthin, Carsten; Wald, Ingo; Munkberg, Jacob (The Eurographics Association, 2016)
      Accelerating ray traversal on data-parallel hardware architectures has received widespread attention over the last few years, but much less research has focused on efficient shading for ray tracing. This is unfortunate ...

    • Local Shape Editing at the Compositing Stage 

      Zubiaga, Carlos Jorge; Guennebaud, Gael; Vergne, Romain; Barla, Pascal (The Eurographics Association, 2016)
      Modern compositing software permit to linearly recombine different 3D rendered outputs (e.g., diffuse and reflection shading) in post-process, providing for simple but interactive appearance manipulations. Renderers also ...

    • Local Signature Quantization by Sparse Coding 

      Boscaini, Davide; Castellani, Umberto (The Eurographics Association, 2013)
      In 3D object retrieval it is very important to define reliable shape descriptors, which compactly characterize geometric properties of the underlying surface. To this aim two main approaches are considered: global, and ...

    • Local Versus Global Triangulations 

      Linsen, Lars; Prautzsch, Hartmut (Eurographics Association, 2001)
      Free form surfaces are commonly represented by triangular or quadrilateral meshes. Often these meshes are obtained from unorganized point sets sampled from some object’s surface. We show that local rather than global ...

    • Local Volume Preservation for Skinned Characters 

      Rohmer, Damien; Hahmann, Stefanie; Cani, Marie-Paule (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Generating plausible deformations of a character skin within the standard production pipeline is a challenge. This paper presents a volume preservation method dedicated to skinned characters. As usual, the character is ...

    • A Local/Global Approach to Mesh Parameterization 

      Liu, Ligang; Zhang, Lei; Xu, Yin; Gotsman, Craig; Gortler, Steven J. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a novel approach to parameterize a mesh with disk topology to the plane in a shape-preserving manner. Our key contribution is a local/global algorithm, which combines a local mapping of each 3D triangle to the ...

    • LOCALIS: Locally-adaptive Line Simplification for GPU-based Geographic Vector Data Visualization 

      Amiraghdam, Alireza; Diehl, Alexandra; Pajarola, Renato (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Visualization of large vector line data is a core task in geographic and cartographic systems. Vector maps are often displayed at different cartographic generalization levels, traditionally by using several discrete ...

    • Localised Topology Correction for Hypertextured Terrains 

      Gamito, Manuel N.; Maddock, Steve C. (The Eurographics Association, 2008)
      Terrains for computer graphics have traditionally been modelled with height fields. In the case of procedurally defined terrains, the height field is generated by a displacement map z

    • Localized Delaunay Refinement for Sampling and Meshing 

      Tamal K. Dey; Joshua A. Levine; Andrew Slatton (2010)
      The technique of Delaunay renement has been recognized as a versatile tool to generate Delaunay meshes of a variety of geometries. Despite its usefulness, it suffers from one lacuna that limits its application. It does not ...

    • Localized Delaunay Refinement for Volumes 

      Dey, Tamal K.; Slatton, Andrew G. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Delaunay refinement, recognized as a versatile tool for meshing a variety of geometries, has the deficiency that it does not scale well with increasing mesh size. The bottleneck can be traced down to the memory usage of ...
