    • Accelerating kd-tree Searches for all k-nearest Neighbours 

      Merry, Bruce; Gain, James; Marais, Patrick (The Eurographics Association, 2013)
      Finding the k nearest neighbours of each point in a point cloud forms an integral part of many point-cloud processing tasks. One common approach is to build a kd-tree over the points and then iteratively query the k nearest ...

    • Automatic Generation of Constructable Brick Sculptures 

      Testuz, Romain; Schwartzburg, Yuliy; Pauly, Mark (The Eurographics Association, 2013)
      Fabrication of LEGO R models in large scale requires careful pre-planning to produce constructable and stable models. We propose a system that, starting with a voxelization of a 3D mesh, merges voxels to form larger bricks, ...

    • 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 ...

    • A Segmentation Transfer Method for Articulated Models 

      Elghoul, Esma; Verroust-Blondet, Anne (The Eurographics Association, 2013)
      In this paper, we propose using a pre-segmented example model to perform semantic-oriented segmentation of non-rigid 3D models of the same class (human, octopus, quadrupeds, etc.). Using the fact that the same type 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 ...

    • Volume Controllable SPH 

      Shinkawa, Masanori; Kawaguchi, Yoichiro (The Eurographics Association, 2013)
      We extend a Predictive Corrective Incompressible SPH (PCISPH) algorithm to a volume controllable SPH algorithm. In order to handle volume changes, we develop a method to control fluid volume. Our method precomputes a ...
