      We evaluate several shadow map algorithms based on warping and partitioning using the maximum perspective aliasing error over the entire view frustum. With respect to our error metric, we show that a range of warping ...
    • Watercolor Illustrations of CAD Data 

      Luft, Thomas; Kobs, Frank; Zinser, Walter; Deussen, Oliver (The Eurographics Association, 2008)
      In this paper we describe a project that integrates a non-photorealistic rendering pipeline into an existing CAD system. The pipeline enables the customers of the CAD company to create aesthetically appealing renderings ...
    • Watergate: Visual Exploration of Water Trajectories in Protein Dynamics 

      Vad, Viktor; Byška, Jan; Jurcík, Adam; Viola, Ivan; Gröller, Eduard; Hauser, Helwig; Marques, Sérgio M.; Damborský, Jiří; Kozlíková, Barbora (The Eurographics Association, 2017)
      The function of proteins is tightly related to their interactions with other molecules. The study of such interactions often requires to track the molecules that enter or exit specific regions of the proteins. This is ...
    • Watermarking and Digital Rights Management - A Pilot DRM System Implementation and Technical Guidelines to Cultural Digitization Projects 

      Tsolis, Dimitrios K.; Nikolopoulos, Spiridon N.; Karatzas, Emmanouil G.; Sioutas, Spiridon A.; Hondrou, E. A.; Mouriki, A. I.; Georgiadou, A. A.; Papatheodorou, Theodore S. (The Eurographics Association, 2006)
      The issue addressed in this paper is at first a brief presentation of the Technical Guidelines for IPR protection and management applied to Greek cultural digitization projects. Secondly, the work focuses on the analysis ...
    • Watertight Ray Traversal with Reduced Precision 

      Vaidyanathan, Karthik; Akenine-Möller, Tomas; Salvi, Marco (The Eurographics Association, 2016)
      Reduced precision bounding volume hierarchies and ray traversal can significantly improve the efficiency of ray tracing through low-cost dedicated hardware. A key approach to enabling reduced precision computations during ...
    • Watertight Scenes from Urban LiDAR and Planar Surfaces 

      Kreveld, Marc van; Lankveld, Thijs van; Veltkamp, Remco C. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      The demand for large geometric models is increasing, especially of urban environments. This has resulted in production of massive point cloud data from images or LiDAR. Visualization and further processing generally require ...
    • Watertight Tessellation using Forward Differencing 

      Moreton, Henry (The Eurographics Association, 2001)
      In this paper we describe an algorithm and hardware for the tessellation of polynomial surfaces. While conventional forward difference-based tessellation is subject to round off error and cracking, our algorithm produces ...
