      We present in this paper a simulation framework that allows a precise and efficient handling of collisions and contacts between deformable moving bodies and their environment. The moving bodies are sampled as meshes whose ...
    • Edge- and substrate-based effects for watercolor stylization 

      Montesdeoca, Santiago E.; Seah, Hock Soon; Bénard, Pierre; Vergne, Romain; Thollot, Joëlle; Rall, Hans-Martin; Benvenuti, Davide (Association for Computing Machinery, Inc (ACM), 2017)
      We investigate characteristic edge- and substrate-based effects for watercolor stylization. These two fundamental elements of painted art play a significant role in traditional watercolors and highly influence the pigment's ...
    • Edge-Avoiding À-TrousWavelet Transform for fast Global Illumination Filtering 

      Dammertz, Holger; Sewtz, Daniel; Hanika, Johannes; Lensch, Hendrik P. A. (The Eurographics Association, 2010)
      We present a fast and simple filtering method designed for ray traced Monte Carlo global illumination images which achieves real-time rates. Even on modern hardware only few samples can be traced for interactive applications, ...
    • Edge-Aware Volume Smoothing Using L0 Gradient Minimization 

      Wang, Qichao; Tao, Yubo; Lin, Hai (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      In volume visualization, noise in regions of homogeneous material and at boundaries between different materials poses a great challenge in extracting, analyzing and rendering features of interest. In this paper, we present ...
    • An Edge-based Approach to Adaptively Refining a Mesh for Cloth Deformation 

      Simnett, Timothy J. R.; Laycock, Stephen D.; Day, Andy M. (The Eurographics Association, 2009)
      Simulating cloth in real-time is a challenging endeavour due to the number of triangles necessary to depict the potentially frequent changes in curvature, in combination with the physics calculations which model the ...
    • Edge-based LBP Description of Surfaces with Colorimetric Patterns 

      Thompson, Elia Moscoso; Biasotti, Silvia (The Eurographics Association, 2018)
      In this paper we target the problem of the retrieval of colour patterns over surfaces. We generalize to surface tessellations the well known Local Binary Pattern (LBP) descriptor for images. The key concept of the LBP is ...
    • An Edge-Face Relational Scheme for Boundary Representations 

      Ansaldi, S.; De Floriani, K.; Falcidienc, B. (Blackwell Publishing Ltd and the Eurographics Association, 1985)
      We propose a relational scheme for representing and modelling regular objects, which is based on the adjacency relations between faces and edges. In this structure, called edge-face graph, the nodes represent the faces and ...
