      Barot, Camille; Burkhardt, Jean-Marie; Lourdeaux, Domitile; Lenne, Dominique (The Eurographics Association, 2011)
      In high risk industries, risk management training has become a major issue. It requires not only to teach rules and procedures, but also to promote a real understanding of the risks that are at stake and to train learners ...
    • VafusQ: A Visual Analytics Application with Data Quality Features to Support the Urban Planning Process 

      Triana, John A.; Zeckzer, Dirk; Hernandez, Jose T.; Hagen, Hans (The Eurographics Association, 2015)
      Fast changing urban systems pose huge challenges for planners and governments. One major challenge is to provide optimized facilities systems fulfilling all the basic citizen needs such as food, education, security, and ...
    • Valence-Driven Connectivity Encoding for 3D Meshes 

      Alliez, Pierre; Desbrun, Mathieu (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      In this paper, we propose a valence-driven, single-resolution encoding technique for lossless compression of triangle mesh connectivity. Building upon a valence-based approach pioneered by Touma and Gotsman22 , we design ...
    • Validation of Quantitative Measures for Edge Bundling by Comparing with Human Feeling 

      Saga, Ryosuke (The Eurographics Association, 2018)
      This paper describes an analysis of the relationship between human cognition and quantitative measures for a visualization method called edge bundling.Aesthetic rules-based measures, namely, mean edge length difference ...
    • Validity Issues for Modular Boundary Models 

      Bruzzone, Elisabetta; De Floriani, Leila (Eurographics Association, 1991)
      Modular boundary models are a class of solid models which describe a solid object as a collection of face-abutting object parts, called components. The Face-to-Face Composition (FFC) model is a specific model of this class, ...
    • VAO++: Practical Volumetric Ambient Occlusion for Games 

      Bokšanský, Jakub; Pospíšil, Adam; Bittner, Jiří (The Eurographics Association, 2017)
      Ambient occlusion is one of the commonly used methods to increase visual fidelity in real-time rendering applications. We propose several extensions of the recently introduced volumetric ambient occlusion method. These ...
    • Variable Bit Rate GPU Texture Decompression 

      Olano, Marc; Baker, Dan; Griffin, Wesley; Barczak, Joshua (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Variable bit rate compression can achieve better quality and compression rates than fixed bit rate methods. None the less, GPU texturing uses lossy fixed bit rate methods like DXT to allow random access and on-the-fly ...
    • Variable k-buffer using Importance Maps 

      Vasilakis, Andreas-Alexandros; Vardis, Konstantinos; Papaioannou, Georgios; Moustakas, Konstantinos (The Eurographics Association, 2017)
      Successfully predicting visual attention can significantly improve many aspects of computer graphics and games. Despite the thorough investigation in this area, selective rendering has not addressed so far fragment visibility ...
    • Variable Length Coding for GPU-Based Direct Volume Rendering 

      Guthe, Stefan; Goesele, Michael (The Eurographics Association, 2016)
      The sheer size of volume data sampled in a regular grid requires efficient lossless and lossy compression algorithms that allow for on-the-fly decompression during rendering. While all hardware assisted approaches are based ...
    • Variable Resolution 4-k Meshes: Concepts and Applications 

      Velho, Luiz; Gomes, Jonas (Blackwell Publishers Ltd and the Eurographics Association, 2000)
