    • 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, ...

    • 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 ...

    • Graph Abstraction for Simplified Proofreading of Slice-based Volume Segmentation 

      Sicat, Ronell B.; Hadwiger, Markus; Mitra, Niloy J. (The Eurographics Association, 2013)
      Volume segmentation is an integral data analysis tool in experimental science. For example, in neuroscience, analysis of 3D volumes of neural structures from electron microscopy data is a key analysis step. Despite advances ...

    • Perceptually Motivated Real-Time Compression of Motion Data Enhanced by Incremental Encoding and Parameter Tuning 

      Firouzmanesh, Amirhossein; Cheng, Irene; Basu, Anup (The Eurographics Association, 2013)
      We address the problem of efficient real-time motion data compression considering human perception. Using incremental encoding plus a database of motion primitives for each key point, our method achieves a higher or ...

    • Real-Time Importance Sampling of Dynamic Environment Maps 

      Lu, Heqi; Pacanowski, Romain; Granier, Xavier (The Eurographics Association, 2013)
      We introduce a simple and effective technique for light-based importance sampling of dynamic environment maps based on the formalism of Multiple Importance Sampling (MIS). The core idea is to balance per pixel the number ...

    • Adaptive Remeshing for Real-Time Mesh Deformation 

      Dunyach, Marion; Vanderhaeghe, David; Barthe, Loïc; Botsch, Mario (The Eurographics Association, 2013)
      We present an adaptive isotropic remeshing technique that is fast enough to be used in interactive applications, such as mesh deformation or mesh sculpting. Previous real-time remeshing techniques are either not adaptive, ...

    • 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 ...

    • 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 ...

    • Centers of Approximate Spherical Symmetry and Radial Symmetry Graphs 

      Giachetti, Andrea; Lovato, Christian (The Eurographics Association, 2013)
      In this paper we propose the possible use of a new type of salient points we call CASS (Centers of Approximate Spherical Symmetry) that are extracted from the Multiscale Area Projection transform described in [GL12]. In ...

    • Seam-Driven Image Stitching 

      Gao, Junhong; Li, Yu; Chin, Tat-Jun; Brown, Michael S. (The Eurographics Association, 2013)
      Image stitching computes geometric transforms to align images based on the best fit of feature correspondences between overlapping images. Seam-cutting is used afterwards to to hide misalignment artifacts. Interestingly ...

    • 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 ...

    • Real-time Collision Detection for Dynamic Hardware Tessellated Objects 

      Nießner, Matthias; Siegl, Christian; Schäfer, Henry; Loop, Charles (The Eurographics Association, 2013)
      We present a novel method for real-time collision detection of patch based, displacement mapped objects using hardware tessellation. Our method supports fully animated, dynamically tessellated objects and runs entirely on ...

    • Real-Time Image-Based Volume Lighting 

      Delalandre, Cyril; Gautron, Pascal; Marvie, Jean-Eudes (The Eurographics Association, 2013)
      The interaction of translucent objects with light creates complex effects such as scattering, absorption and volumetric shadows. While most accurate rendering approaches resort to heavy computations, recent needs in ...

    • Automatic Modeling of Planar-Hinged Buildings 

      Garcia-Dorado, Ignacio; Aliaga, Daniel G. (The Eurographics Association, 2013)
      We present a framework to automatically model and reconstruct buildings in a dense urban area. Our method is robust to noise and recovers planar features and sharp edges, producing a water-tight triangulation suitable for ...

    • Automatic Parameter Control for Metropolis Light Transport 

      Zsolnai, Károly; Szirmay-Kalos, László (The Eurographics Association, 2013)
      Sophisticated global illumination algorithms usually have several control parameters that need to be set appropriately in order to obtain high performance and accuracy. Unfortunately, the optimal values of these parameters ...

    • Generating Pseudo-3D Painting Based on Visual Saliency and Composition Rules 

      Zheng, Zhibin; Zhang, Yan; Sun, Zhengxing (The Eurographics Association, 2013)
      Pseudo-3D painting shows stereoscopic artistic effect in the 2D plane and displays artistic conception as the known verse "Far, near, high, low-no two parts alike", it brings a true feeling of stereo space to observers. ...
