    • Triangulating Point Set Surfaces with Bounded Error 

      Scheidegger, Carlos E.; Fleishman, Shachar; Silva, Claudio T. (The Eurographics Association, 2005)
      We introduce an algorithm for constructing a high-quality triangulation directly from Point Set Surfaces. Our algorithm requires no intermediate representation and no post-processing of the output, and naturally handles ...

    • Triangulations with Locally Optimal Steiner Points 

      Erten, Hale; Uengoer, Alper (The Eurographics Association, 2007)
      We present two new Delaunay refinement algorithms, the second an extension of the first. For a given input domain (a set of points in the plane or a planar straight line graph), and a threshold angle a, the Delaunay ...

    • Triggering the Past: Cultural Heritage Interpretation Using Augmented and Virtual Reality at a Living History Museum 

      Shitut, Kunal; Geigel, Joe; Decker, Juilee; Jacobs, Gary; Doherty, Amanda (The Eurographics Association, 2021)
      In this paper, we present a use case for the introduction of historical digital characters in the context of a living history museum. We describe a prototype system and framework that enables the use of augmented and virtual ...

    • The Trilateral Filter for High Contrast Images and Meshes 

      Choudhury, Prasun; Tumblin, Jack (The Eurographics Association, 2003)
      We present a new, single-pass nonlinear filter for edge-preserving smoothing and visual detail removal for N dimensional signals in computer graphics, image processing and computer vision applications. Built from two ...

    • 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 ...

    • 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 ...

    • 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 ...

    • Tutbury Castle : Recovering a period site 

      Inman, Laurence; Morris, Phil (The Eurographics Association, 2013)
      This paper proposes a method for virtual reconstruction of a ruin in three dimensions, using a number of sources. The case study that accompanies this paper shows an example of the virtual restoration of Tutbury castle in ...

    • Two Algorithms for Fast Reclustering of Dynamic Meshed Surfaces 

      Carr, Nathan A.; Hart, John C. (The Eurographics Association, 2004)
      Numerous mesh algorithms such as parametrization, radiosity, and collision detection require the decomposition of meshes into a series of clusters. In this paper we present two novel approaches for maintaining mesh clusterings ...

    • Two Methods for Fast Ray-Cast Ambient Occlusion 

      Laine, Samuli; Karras, Tero (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Ambient occlusion has proven to be a useful tool for producing realistic images, both in offline rendering and interactive applications. In production rendering, ambient occlusion is typically computed by casting a large ...

    • Two Stage Importance Sampling for Direct Lighting 

      Cline, David; Egbert, Parris K.; Talbot, Justin F.; Cardon, David L. (The Eurographics Association, 2006)
      We describe an importance sampling method to generate samples based on the product of a BRDF and an environment map or large light source. The method works by creating a hierarchical partition of the light source based on ...

    • A Two-Dimensional Frame Buffer Processor 

      Kaufman, Arie (The Eurographics Association, 1987)
      The two-dimensional Frame Buffer Processor (FBP) is part of a proposed raster graphics computer architecture. It is a hardware-oriented organisation of a variation of a bitblt engine with a much richer repertoire. In ...

    • Two-Handed Through-the-Lens-Techniques for Navigation in Virtual Environments 

      Stoev, Stanislav L.; Schmalstieg, Dieter; Straßer, Wolfgang (The Eurographics Association, 2001)
      We present a tool set of techniques for navigation in virtual environments. Based on a through-the-lens concept, the user is enabled to simultaneously view the surrounding virtual world and an arbitrary location of the ...

    • A Two-Level Cascade Classification Algorithm for Real-Time Bifurcation Detection in CTA Images of Blood Vessels 

      Novikov, Alexey A.; Wimmer, Maria; Major, David; Bühler, Katja (The Eurographics Association, 2015)

    • Two-level Pipelining of Systolic Array Graphics Engines 

      Jayasinghe, J. A. K. S.; Herrmann, O. E. (The Eurographics Association, 1989)
      In a systolic array, the maximum operating speed is determined by the most complex operation performed. In a systolic army graphics engine, capable of generating high quality images, one has to perform complex operations ...

    • Two-Pass Image and Volume Rotation 

      Chen, Baoquan; Kaufman, Arie (The Eurographics Association, 2001)
      We present a novel two-pass approach for both 2D image and 3D volume rotation. Each pass is a pseudo shear. However, it has a similar regularity as a pure shear in that a beam remains rigid while being sheared. Furthermore, ...
