    • Bilateral Hermite Radial Basis Functions for Contour-based Volume Segmentation 

      Ijiri, Takashi; Yoshizawa, Shin; Sato, Yu; Ito, Masaaki; Yokota, Hideo (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      In this paper, we propose a novel contour-based volume image segmentation technique. Our technique is based on an implicit surface reconstruction strategy, whereby a signed scalar field is generated from user-specified ...

    • Coupled Quasi-harmonic Bases 

      Kovnatsky, Artiom; Bronstein, Michael M.; Bronstein, Alexander M.; Glashoff, Klaus; Kimmel, Ron (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      The use of Laplacian eigenbases has been shown to be fruitful in many computer graphics applications. Today, state-of-the-art approaches to shape analysis, synthesis, and correspondence rely on these natural harmonic bases ...

    • Direct Contouring of Implicit Closest Point Surfaces 

      Auer, Stefan; Westermann, Rüdiger (The Eurographics Association, 2013)
      Constructing a (signed) distance field and contouring its zero level set are two important steps in many surface reconstruction methods. While most high-quality distance transforms compute the distance to the surface as ...

    • Modeling Terrains and Subsurface Geology 

      Natali, Mattia; Lidal, Endre M.; Parulek, Julius; Viola, Ivan; Patel, Daniel (The Eurographics Association, 2013)
      The process of creating terrain and landscape models is important in a variety of computer graphics and visualization applications, from films and computer games, via flight simulators and landscape planning, to scientific ...

    • Time-variant Volumetric Colors for Metamorphosis 

      Fryazinov, Oleg; Sanchez, Mathieu; Adzhiev, Valery; Pasko, Alexander (The Eurographics Association, 2013)
      We propose to treat any changes in colors and textures in shape metamorphosis between two objects as time- dependent transformations of the volumetric distribution of materials. The main idea is to represent geometry of ...

    • Transfinite Surface Patches Using Curved Ribbons 

      Várady, Tamás; Salvi, Péter; Rockwood, Alyn (The Eurographics Association, 2013)
      An important problem in Computer Aided Design is to create digital representations for complex free-form objects that produce nice, predictable shapes and facilitate real-time editing in 3D. The clue to curve network-based ...
