      We present a novel method to generate a virtual character's multi-contact poses adaptive to the various shapes of the environment. Given the user-specified center of mass (CoM) position and direction as inputs, our method ...
    • Fast and Scalable Mesh Superfacets 

      Simari, Patricio; Picciau, Giulia; Floriani, Leila De (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      In the field of computer vision, the introduction of a low-level preprocessing step to oversegment images into superpixels - relatively small regions whose boundaries agree with those of the semantic entities in the scene ...
    • Fast Feature-Oriented Visual Connection for Large Image Collections 

      Yan, Qingan; Xu, Zhan; Xiao, Chunxia (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Deriving the visual connectivity across large image collections is a computationally expensive task. Different from current image-oriented match graph construction methods which build on pairwise image matching, we present ...
    • Fractional Reyes-Style Adaptive Tessellation for Continuous Level of Detail 

      Liktor, Gabor; Pan, Minghao; Dachsbacher, Carsten (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      In this paper we present a fractional parametric splitting scheme for Reyes-style adaptive tessellation. Our parallel algorithm generates crack-free tessellation from a parametric surface, which is also free of sudden ...
    • G2 Surface Interpolation Over General Topology Curve Networks 

      Salvi, Péter; Várady, Tamás (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      The basic idea of curve network-based design is to construct smoothly connected surface patches, that interpolate boundaries and cross-derivatives extracted from the curve network. While the majority of applications demands ...
    • Hybrid Particle-grid Modeling for Multi-scale Droplet/Spray Simulation 

      Yang, Lipeng; Li, Shuai; Hao, Aimin; Qin, Hong (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      This paper presents a novel hybrid particle-grid method that tightly couples Lagrangian particle approach with Eulerian grid approach to simulate multi-scale diffuse materials varying from disperse droplets to dissipating ...
    • Illuminant Aware Gamut-Based Color Transfer 

      Nguyen, Rang M. H.; Kim, Seon Joo; Brown, Michael S. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      This paper proposes a new approach for color transfer between two images. Our method is unique in its consideration of the scene illumination and the constraint that the mapped image must be within the color gamut of the ...
    • Incompressible SPH using the Divergence-Free Condition 

      Kang, Nahyup; Sagong, Donghoon (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      In this paper, we present a novel SPH framework to simulate incompressible fluid that satisfies both the divergencefree condition and the density-invariant condition. In our framework, the two conditions are applied ...
    • Interactive Image-Guided Modeling of Extruded Shapes 

      Cao, Yan-Pei; Ju, Tao; Fu, Zhao; Hu, Shi-Min (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      A recent trend in interactive modeling of 3D shapes from a single image is designing minimal interfaces, and accompanying algorithms, for modeling a specific class of objects. Expanding upon the range of shapes that existing ...
    • Learning Natural Colors for Image Recoloring 

      Huang, Hao-Zhi; Zhang, Song-Hai; Martin, Ralph R.; Hu, Shi-Min (The Eurographics Association and John Wiley and Sons Ltd., 2014)
