    • Triplanar Displacement Mapping for Terrain Rendering 

      Weiss, Sebastian; Bayer, Florian; Westermann, Rüdiger (The Eurographics Association, 2020)
      Heightmap-based terrain representations are common in computer games and simulations. However, adding geometric details to such a representation during rendering on the GPU is difficult to achieve. In this paper, we propose ...
    • TRIPS - A Scalable Spatial Sound Library for OpenSG 

      Neumann, Tomas; Fünfzig, Christoph; Fellner, Dieter W. (The Eurographics Association, 2003)
      We present a Sound Library that is scalable on several computers and that brings the idea of a self-organized scenegraph to the Sound Library's interface. It supports the implementation of audio features right from the ...
    • Trivariate Biharmonic B‐Splines 

      Hou, Fei; Qin, Hong; Hao, Aimin (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      .In this paper, we formulate a novel trivariate biharmonic B‐spline defined over bounded volumetric domain. The properties of bi‐Laplacian have been well investigated, but the straightforward generalization from bivariate ...
    • Trivial Connections on Discrete Surfaces 

      Keenan Crane; Mathieu Desbrun; Peter Schroeder (2010)
      This paper presents a straightforward algorithm for constructing connections on discrete surfaces that are as smooth as possible everywhere but on a set of isolated singularities with given index. We compute these connections ...
    • Trust in Information Visualization 

      Mayr, Eva; Hynek, Nicole; Salisu, Saminu; Windhager, Florian (The Eurographics Association, 2019)
      Trust is an important factor that mediates whether a user will rely and build on the information displayed in a visualization. Research in other fields shows that there are different mechanisms of trust building: Users ...
    • TrustNeighborhoods: Visualizing Trust in Distributed File Sharing Systems 

      Elmqvist, Niklas; Tsigas, Philippas (The Eurographics Association, 2007)
      We present TrustNeighborhoods, a security trust visualization for situational awareness on the Internet aimed at novice and intermediate users of a distributed file sharing system. The TrustNeighborhoods technique uses the ...
    • TrustVis 2019: Frontmatter 

      Kosara, Robert; Lawonn, Kai; Linsen, Lars; Smit, Noeska (The Eurographics Association, 2019)
    • TSS BVHs: Tetrahedron Swept Sphere BVHs for Ray Tracing Subdivision Surfaces 

      Du, Peng; Kim, Yong-Jun; Yoon, Sung Eui (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a novel, compact bounding volume hierarchy, TSS BVH, for ray tracing subdivision surfaces computed by the Catmull-Clark scheme. We use Tetrahedron Swept Sphere (TSS) as a bounding volume to tightly bound limit ...
    • tStudy of Augmented RealityMethods for Real Time Recognitionand Tracking of Untextured 3DModels in Monocular Images 

      Alvarez Ponga, Hugo (Alvarez Ponga, dec, 2011)
      The main challenge of an augmented reality system is to obtain perfectalignment between real and virtual objects in order to create the illusionthat both worlds coexist. To that end, the position and orientation of theobserver ...
    • The Tumor Therapy Manager and its Clinical Impact 

      Rössling, Ivo; Dornheim, Jana; Dornheim, Lars; Boehm, Andreas; Preim, Bernhard (The Eurographics Association, 2011)
      Visual exploration of CT and MRI datasets in clinical practice is still dominated by slice-based viewing. Volume rendering is now widely available but seen primarily as a tool for a fast overview, and only rarely as a ...
    • Tunable Robustness: An Artificial Contact Strategy with Virtual Actuator Control for Balance 

      Silva, D. B.; Nunes, R. F.; Vidal, C. A.; Cavalcante‐Neto, J. B.; Kry, P. G.; Zordan, V. B. (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Physically based characters have not yet received wide adoption in the entertainment industry because control remains both difficult and unreliable. Even with the incorporation of motion capture for reference, which adds ...
    • Tuning of Algorithms for Independent Task Placement in the Context of Demand-Driven Parallel Ray Tracing 

      Plachetka, T. (The Eurographics Association, 2004)
      This paper investigates assignment strategies (load balancing algorithms) for process farms which solve the problem of online placement of a constant number of independent tasks with given, but unknown, time complexities ...
    • Tuning Subdivision by Minimising Gaussian Curvature Variation Near Extraordinary Vertices 

      Augsdoerfer, U.H.; Dodgson, N.A.; Sabin, M.A. (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      We present a method for tuning primal stationary subdivision schemes to give the best possible behaviour near extraordinary vertices with respect to curvature variation.Current schemes lead to a limit surface around ...
