    • Shape Analysis for Augmented Topological Shape Descriptor 

      Symonova, Olga; Amicis, Raffaele De (The Eurographics Association, 2007)
      In this work we propose a scheme for analysis of the shape of a 3D model.We use Extended Reeb Graph to describe the topological structure of the model which we further enrich with extracted geometrical features. The nodes ...
    • 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 ...
    • Spinoff - Transferring Energy between Real and Virtual Worlds 

      Groenegress, Christoph; Slater, Mel; Tamke, Martin; Thomsen, Mette Ramsgard (The Eurographics Association, 2007)
      There is a widening gap between interaction devices for Virtual Environments and other factors such as graphical realism, accessibility and complexity. To address this problem, we developed a Mixed Reality environment that ...
    • Stabilized Noise 

      Yoon, Jong-Chul; Lee, In-Kwon (The Eurographics Association, 2007)
      Perlin noise is generated by interpolation of a pre-defined random number table. However since the random number table is generated without considering the ideal properties of noise for computer graphics, the resulting ...
    • State-of-the-Art Computer Graphics in Neurosurgical Planning and Risk Assessment 

      Köhn, Alexander; Weiler, Florian; Klein, Jan; Konrad, Olaf; Hahn, Horst; Peitgen, Heinz-Otto (The Eurographics Association, 2007)
      We present a novel software assistant that unlocks new potentials in neurosurgical planning and risk assessment. It allows surgeons to approach the task in an intuitive manner, by providing them with the possibility to ...
    • Take a Stroll in Another World 

      Ruttkay, Zsofia; Orbons, Erik (The Eurographics Association, 2007)
      Another World II is a print by the famous Dutch artist M. C. Escher, depicting a cube with arch-like openings on each side. What makes the print interesting is that the depicted views in the arches are inconsistent, leaving ...
    • 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 ...
    • View-based Shape Similarity using Mutual Information Spheres 

      García, Francisco González; Feixas, Miquel; Sbert, Mateu (The Eurographics Association, 2007)
      We present a new method for computing the shape similarity between 3D polygonal models using an informationtheoretic viewpoint selection framework. Given a 3D model, a sphere of viewpoints surrounding this model is used ...
    • Virtual Agent Navigation in Open Spaces using Iterative Shrinking Polygons 

      Haciomeroglu, Murat; Laycock, Robert; Day, Andy (The Eurographics Association, 2007)
      Populating an urban environment with a virtual crowd provides a dynamic element to an otherwise static scene; bringing the virtual environment to life. One of the fundamental components governing the fidelity of the scene ...
    • 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 ...
