    • 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 ...

    • 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 ...

    • 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 ...

    • Feature-preserving Direct Blue Noise Sampling for Surface Meshes 

      Peyrot, Jean-Luc; Payan, Frédéric; Antonini, Marc (The Eurographics Association, 2013)
      We present a new direct Poisson disk sampling for surface meshes. Our objective is to sample triangular meshes, while satisfying good blue noise properties, but also preserving features. Our method combines a feature ...

    • 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 ...

    • Automatic Convergence Adjustment for Stereoscopy using Eye Tracking 

      Fisker, Martin; Gram, Kristoffer; Thomsen, Kasper Kronborg; Vasilarou, Dimitra; Kraus, Martin (The Eurographics Association, 2013)
      When using stereoscopic displays, decoupling between convergence and accommodation can cause eyestrain. This paper proposes an adjustment method to automatically fit convergence at user fixation depth to accommodation by ...

    • Using Webcams for Product Presentations in HTML5 

      Borg, Mathias; Kraus, Martin (The Eurographics Association, 2013)
      The Media Capture and Streams API ("getUserMedia API") enables plug-in free webcam support in HTML5. This opens new ways of interacting with visualisations using open web standards. In this work, two techniques are proposed ...

    • Reverse Skew-T - A Cloudmaking Tool for CG 

      McLoughlin, Leigh; Anderson, Eike Falk (The Eurographics Association, 2013)
      We present 'Reverse Skew-T', a tool that allows users to direct a physically inspired simulation of layered clouds. To achieve this, we extend existing models for cloud simulation and provide a graphical user interface for ...

    • On Depth-testing Wide Outlines 

      Szécsi, László; Hajagos, Balázs; Umenhoffer, Tamás (The Eurographics Association, 2013)
      We investigate the visibility problem of crease outlines in stylistic and engineering rendering. We discuss why the problem is ill-defined, and offer two different, consistent formulations that lead to artistic and technical ...

    • 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 ...

    • Real-time Control and Stopping of Fluids 

      Zsolnai, Károly; Szirmay-Kalos, László (The Eurographics Association, 2013)
      In this paper we address the fluid control problem, where an arbitrary density distribution (a shape of any kind) is given, and forces are exerted to get the fluid to flow into this shape and stop when the target distribution ...

    • Multi-Camera Acquisition and Placement Strategy for Displaying High-Resolution Images for Telepresence Systems 

      Islam, Tariqul; Ohl, Stephan; Staadt, Oliver (The Eurographics Association, 2013)
      Life-size high-resolution telepresence systems, used for remote collaboration, face the problem of transmitting huge data from multiple viewpoints. We present different strategies focusing on efficient camera selection and ...

    • A Distributed and Collaborative vSLAM Framework for Real-Time Localisation in Huge Environments for Mobile Devices 

      Barrena, Nagore; Sánchez, Jairo R.; García-Alonso, Alejandro (The Eurographics Association, 2013)
      This poster proposes a collaborative vSLAM system for mobile Augmented Reality applications in huge environments. The system combines the efficiency of local vSLAM methods with the accuracy of large-scale mapping techniques. ...

    • Volume Ray Casting quality estimation in terms of Peak Signal-to-Noise Ratio 

      Gavrilov, Nikolay; Turlapov, V. (The Eurographics Association, 2013)
      In spite of a large number of techniques aimed for improvement of Direct Volume Rendering (DVR) quality and performance proposed in the literature, there is a lack of approaches for numerical quality estimation of the ...

    • A Sensor Based Approach to Outdoor Illumination Estimation for Augmented Reality Applications on Mobile Devices 

      Barreira, João; Magalhães, Luís; Bessa, Maximino (The Eurographics Association, 2013)
      Realistic Augmented Reality applications require integrating virtual objects in the real world in a seamless visual way. The main problem to obtain a perfect visual augmentation is rendering the virtual objects with ...

    • Poisson Image Analogy: Texture-Aware Seamless Cloning 

      Yoshizawa, Shin; Yokota, Hideo (The Eurographics Association, 2013)
      Synthesizing two images with seamless boundaries, i.e. seamless image cloning, is important and has many useful applications in CG. Previous approaches do not produce realistic results if texture details of the two images ...

    • Towards a Physically Plausible Constrained Shader Graph System for Predictive Rendering 

      Pavlík, Ivo; Wilkie, Alexander (The Eurographics Association, 2013)
      We present ongoing work on a modeling tool for Predictive Rendering based on the popular idea of shader graphs for description of object surfaces. To guarantee physical plausibility of the resulting materials, we use a ...
