    • Wait-Free Shared-Memory Irradiance Cache 

      Dubla, Piotr; Debattista, Kurt; Santos, Luis Paulo; Chalmers, Alan (The Eurographics Association, 2009)
      The irradiance cache (IC) is an acceleration data structure which caches indirect diffuse irradiance values within the context of a ray tracing algorithm. In multi-threaded shared memory parallel systems the IC must be ...
    • Wake Synthesis For Shallow Water Equation 

      Pan, Zherong; Huang, Jin; Tong, Yiying; Bao, Hujun (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      In fluid animation, wake is one of the most important phenomena usually seen when an object is moving relative to the flow. However, in current shallow water simulation for interactive applications, this effect is greatly ...

      Freudenberg, Bert; Masuch, Maic; Strothotte, Thomas (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      In this paper we show how a game engine designed to generate photorealistic images can be extended to produce non-photorealistic and hybrid renditions. We introduce new hardware-based methods to accomplish pen-and-ink ...
    • Walking On Broken Mesh: Defect-Tolerant Geodesic Distances and Parameterizations 

      Campen, Marcel; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Efficient methods to compute intrinsic distances and geodesic paths have been presented for various types of surface representations, most importantly polygon meshes. These meshes are usually assumed to be well-structured ...
    • Walking with Pens 

      Kolhoff, Philipp; Preuß, Jacqueline; Loviscach, Jörn (The Eurographics Association, 2005)
      Believable 3D animation of walking or running characters still requires complex motion capture technology or extensive skills in manual keyframing. We present an inexpensive, yet natural input method: The user walks on ...

      Spallazzo, Davide; Ceconello, Mauro; Lenz, R. (The Eurographics Association, 2011)
      The paper describes Looking for Achille Castiglioni - LfAC - a mobile location-based application designed to lead visitors to the discovery of Achille Castiglioni's projects in downtown Milan. The renowned architect and ...
    • The Wall of Knowledge 

      Saleh, Fathi; Nabil, Mohammad; Sameer, Nessma (IEEE, 2015)
      The Wall of Knowledge is a new Virtual Museum installation that was developed by CULTNAT (Center for Documentation of Cultural and Natural Heritage) in 2014.
    • Wall Painting Reconstruction Using a Genetic Algorithm 

      Sizikova, Elena; Funkhouser, Thomas (The Eurographics Association, 2016)
      Global reconstruction of two-dimensional wall paintings (frescoes) from fragments is an important problem for many archaeological sites. The goal is to find the global position and rotation for each fragment so that all ...
    • A War Torn Memory Palace: Animating narratives of remembrance 

      Kenderdine, Sarah; Mckenzie, Heidi (The Eurographics Association, 2013)
      ECLOUD WWI (2012) is a custom designed 9-metre by 3.5-metre interactive 3D projection environment and application developed by the Applied Laboratory for Interactive Visualization and Embodiment (ALIVE), City University ...
    • Warp-based Motion Compensation for Endoscopic Kymography 

      Schneider, David C.; Hilsmann, Anna; Eisert, Peter (The Eurographics Association, 2011)
      Endoscopic videokymography is a method for visualizing the motion of the plica vocalis (vocal folds) for medical diagnosis. The diagnostic interpretability of a kymogram deteriorates if camera motion interferes with vocal ...
    • Warp-based Near-Regular Texture Analysis for Image-based Texture Overlay 

      Hilsmann, Anna; Schneider, David C.; Eisert, Peter (The Eurographics Association, 2011)
      Image-based texture overlay or retexturing is the process of augmenting a surface in an image or a video sequence with a new, synthetic texture. Some properties of the original texture such as texture distortion as well ...
    • Warped Textures for UV Mapping Encoding 

      Sorkine, Olga; Cohen-Or, Daniel (Eurographics Association, 2001)
      This paper introduces an implicit representation of the u; v texture mapping. Instead of using the traditional explicit u; v mapping coordinates, a non-distorted piecewise embedding of the triangular mesh is created, on ...
    • Warping and Partitioning for Low Error Shadow Maps 

      Lloyd, D. Brandon; Tuft, David; Yoon, Sung-eui; Manocha, Dinesh (The Eurographics Association, 2006)
      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 ...
