    • A Pen-based Interface for Generating Graphical Reports of Findings in Cardiac Catheterization 

      Mori, Yuki; Igarashi, Takeo; Haraguchi, Ryo; Nakazawa, Kazuo (The Eurographics Association, 2007)
      This paper introduces a pen-based interface for the graphical reporting of findings in cardiac catheterization. The user can interactively draw, erase, move, and deform coronary arteries as well as record stenoses on them. ...
    • Fast Hierarchical 3D Distance Transforms on the GPU 

      Cuntz, Nicolas; Kolb, Andreas (The Eurographics Association, 2007)
      This paper describes a fast approximate approach for the GPU-based computation of 3D Euclidean distance transforms (DT), i.e. distance fields with associated vector information to the closest object point. Our hierarchical ...
    • A Unified Interpolatory and Approximation sqrt-3 Subdivision Scheme 

      Lin, Shujin; Luo, Xiaonan (The Eurographics Association, 2007)
      We have found that there is a relationship between the cubic B-spline and four-point curve subdivision method. In the paper it is used to deduce interpolatory subdivision schemes from cubic B-spline based approximation ...
    • Pareto-Based Perceptual Metric for Imperceptible Simplification on Mobile Displays 

      Wu, Fan; Agu, Emmanuel; Lindsay, Clifford (The Eurographics Association, 2007)
      Graphics on mobile devices has become popular because untethered computing is convenient and increases pro- ductivity. Mobile displays come in different resolutions that affect the scene Level-of-Detail (LoD) that users ...
    • Analysis of the Pulmonary Vein Ostia using Cardiac 4DCT for Radiosurgical Ablation 

      Sumanaweera, Thilaka; Conti, Francois; Maguire, Patrick (The Eurographics Association, 2007)
      A software tool to analyze 4D cardiac CT data sets for planning radiosurgical ablations in the heart is presented. Volume rendering and data processing are performed using a GPU. The user visualizes the data from inside ...
    • Enforcing Scene Constraints in Single View Reconstruction 

      Lourakis, Manolis; Argyros, Antonis (The Eurographics Association, 2007)
      Three-dimensional reconstruction from a single view is an under-constrained process that relies critically upon the availability of prior knowledge about the imaged scene. This knowledge is assumed to be supplied by a user ...
    • Adaptive Abstraction of 3D scenes in Real-Time 

      Redmond, Niall; Dingliana, John (The Eurographics Association, 2007)
      We present an approach for creating abstracted renderings of 3D scenes in real-time. We create painterly renderings with edge detail using varying levels of abstraction dependent on regions of interest within a scene. Image ...
    • Real-Time 3D Lettering with a 2D Font Engine 

      Heise, Sebastian; Loviscach, Jörn (The Eurographics Association, 2007)
      Standard texturing shows a number of problems with 3D objects such as road signs, labels, or books. If letters are displayed at too large a scale, textures show blurred instead of hard edges; if letters are displayed at ...
    • Simultaneous Visualization of Preoperative Planning Models and Intraoperative 2D Ultrasound for Liver Surgery 

      Hansen, Christian; Köhn, Alexander; Zidowitz, Stephan; Peitgen, Heinz-Otto; Ritter, Felix (The Eurographics Association, 2007)
      This paper introduces new techniques for simultaneous visualization of preoperative planning models and intraoperative 2D ultrasound for open liver surgery. The driving motivation for our work is to improve the visual ...
    • Imperceptible Calibration for Radiometric Compensation 

      Zollmann, Stefanie; Bimber, Oliver (The Eurographics Association, 2007)
      We present a novel multi-step technique for imperceptible geometry and radiometry calibration of projectorcamera systems. Our approach can be used to display geometry and color corrected images on non-optimized surfaces ...
    • Liquid Diffusion Model that Accounts for a Variety of Dyeing Parameters 

      Yuki, Morimoto; Tanaka, Masayuki; Tsuruno, Reiji; Tomimatsu, Kiyoshi (The Eurographics Association, 2007)
      This paper describes a method for simulating and visualizing dyeing based on weave patterns and the physical parameters of the threads and the dye. We apply Fick s second law with a variable diffusion coefficient, which ...
    • Volumetric Normal Mapping in Rendering of Multivariate Volume Data 

      Seipel, Stefan (The Eurographics Association, 2007)
      The work presented in this paper introduces volumetric normal maps for producing visual structure in direct volume rendering (DVR) of 3D data for the purpose of visualizing multiple attributes in a 3D volume. We use ...
    • Improved Skeleton Computation of an Encoded Volume 

      Ayala, Dolors (The Eurographics Association, 2007)
      In this communication, we present an improvement of an existing thinning algorithm that computes a surface skeleton from a binary volume. The method makes an intensive use of Boolean operations and works on a special ...
