    • Computing Curve Skeletons from Medial Surfaces of 3D Shapes 

      Telea, Alexandru; Jalba, Andrei C. (The Eurographics Association, 2012)
      Skeletons are powerful shape descriptors with many applications in shape processing, reconstruction and matching. In this paper we show that in 3D, curve skeletons can be extracted from surface skeletons in the same manner ...

    • Enhanced Sphere Tracing 

      Keinert, Benjamin; Schäfer, Henry; Korndörfer, Johann; Ganse, Urs; Stamminger, Marc (The Eurographics Association, 2014)
      In this paper we present several performance and quality enhancements to classical sphere tracing: First, we propose a safe, over-relaxation-based method for accelerating sphere tracing. Second, a method for dynamically ...

    • Modelling of Clouds from a Hemispherical Image 

      Alldieck, Thiemo; Lundtoft, Dennis H.; Montanari, Niels; Nikolov, Ivan; Vlaykov, Iskren G.; Madsen, Claus B. (The Eurographics Association, 2014)
      This paper presents an image-based method for modelling clouds. Unlike previous image-based approaches, a hemispherical photograph is used as input, enabling to consider an entire sky instead of merely a portion. Our method ...

    • Non-Uniform Spherical Light Fields 

      Blasco, J.; Abad, F.; Camahort, E.; Vivó, R. (The Eurographics Association, 2021)
      The study of the light field, as a function defining the radiance along the different viewing directions of a scene, started more than a decade ago and is still ongoing due to its interesting applications. Among the different ...

    • Topological Visualisation Techniques for the Understanding of Lattice Quantum Chromodynamics (LQCD) Simulations 

      Thomas, Dean P.; Borgo, Rita; Hands, Simon (The Eurographics Association, 2016)
      The use of topology for visualisation applications has become increasingly popular due to its ability to summarise data at a high level. Criticalities in scalar field data are used by visualisation methods such as the Reeb ...

    • Visualizing a Spherical Geological Discrete Element Model of Fault Evolution 

      Longshaw, Stephen M.; Turner, Martin J.; Finch, Emma (The Eurographics Association, 2012)
      Discrete Element Modelling (DEM) is a numerical technique that uses a system of interacting discrete bodies to simulate the movement of material being exposed to external forces. This technique is often used to simulate ...

    • Volumetric Spot Noise for Procedural 3D Shell Texture Synthesis 

      Pavie, Nicolas; Gilet, Guillaume; Dischler, Jean-Michel; Galin, Eric; Ghazanfarpour, Djamchid (The Eurographics Association, 2016)
      In this paper, we present an extension of the Locally Controlled Spot Noise and a visualization pipeline for volumetric fuzzy details synthesis. We extend the noise model to author volumetric fuzzy details using filtered ...
