    • SaarCOR - A Hardware Architecture for Ray Tracing 

      Schmittler, Jörg; Wald, Ingo; Slusallek, Philipp (The Eurographics Association, 2002)
      The ray tracing algorithm is well-known for its ability to generate high-quality images and its flexibility to support advanced rendering and lighting effects. Interactive ray tracing has been shown to work well on clusters ...
    • Safe Walking Zones: Visual Guidance for Redirected Walking in Confined Real-World Spaces 

      Lubos, Paul; Bruder, Gerd; Steinicke, Frank (The Eurographics Association, 2018)
      Walking is usually considered the most natural form of self-motion in a virtual environment (VE). However, the confined physical workspace of typical virtual reality (VR) labs often prevents natural exploration of larger ...
    • SafeGI: Type Checking to Improve Correctness in Rendering System Implementation 

      Ou, Jiawei; Pellacini, Fabio (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Historically, rendering system development has been mainly focused on improving the numerical accuracy of the rendering algorithms and their runtime efficiency. In this paper, we propose a method to improve the correctness ...
    • SAH KD-Tree Construction on GPU 

      Wu, Zhefeng; Zhao, Fukai; Liu, Xinguo (ACM, 2011)
      KD-tree is one of the most efficient acceleration data structures for ray tracing. In this paper, we present a kd-tree construction algorithm that is precisely SAH-optimized and runs entirely on GPU. We construct the tree ...
    • A Salience-based Quality Metric for Visualization 

      Jänicke, Heike; Chen, Min (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Salience detection is a principle mechanism to facilitate visual attention. A good visualization guides the observer s attention to the relevant aspects of the representation. Hence, the distribution of salience over a ...
    • Salient Representation of Volume Data 

      Hladuvka, Jiri; König, Andreas; Gröller, Eduard (The Eurographics Association, 2001)
      We introduce a novel method for identification of objects of interest in volume data. Our approach conveys the information contained in two essentially different concepts, the object s boundaries and the narrow solid ...
    • SAMBA: Steadied Choreographies 

      Rossignac, Jarek; Luffel, Mark; Vinacua, Alvar (The Eurographics Association, 2012)
      Given the start positions of a group of dancers, a choreographer specifies their end positions and says: ''Run!'' Each dancer has the choice of his/her motion. These choices influence the perceived beauty (or grace) of the ...
    • Sample Based Visibility for Soft Shadows using Alias-free Shadow Maps 

      Sintorn, Erik; Eisemann, Elmar; Assarsson, Ulf (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper introduces an accurate real-time soft shadow algorithm that uses sample based visibility. Initially, we present a GPU-based alias-free hard shadow map algorithm that typically requires only a single render pass ...
    • Sampling Point-Set Implicits 

      Proenca, Joao; Jorge, Joaquim A.; Sousa, Mario C. (The Eurographics Association, 2007)
      We present a novel approach for point-set implicit surface sampling that is able to rapidly distribute particles over the surface of 3D objects. Our methods benefit from the inner structure of a MPU implicit to obtain a ...
    • A Sampling Theorem for MLS Surfaces 

      Bremer, Peer-Timo; Hart, John C. (The Eurographics Association, 2005)
      Recently, point set surfaces have been the focus of a large number of research efforts. Several different methods have been proposed to define surfaces from points and have been used in a variety of applications. However, ...
    • Sarcophagus of the Spouses Installation - Intersection Across Archaeology, 3D Video Mapping and Holographic Techniques Combined with Immersive Narrative Environments and Scenography 

      Fischnaller, Franz; Guidazzoli, Antonella; Imboden, Silvano; Luca, Daniele De; Liguori, Maria Chiara; Russo, Alfonsina; Lucia, Maria Anna De; Cosentino, Rita (IEEE, 2015)
      This paper presents the Sarcophagus of the Spouses installation, an audiovisual performance and exhibit combining 3D video mapping, holographic techniques, computer graphics, high definition visualization with 3D reconstruction ...
    • SCA 2016: Frontmatter 

      Ladislav Kavan; Chris Wojtan (Eurographics Association, 2016)
    • Scaffolding - Design issues in single and collaborative virtual environments for social skills learning 

      Kerr, Steven J. (The Eurographics Association, 2002)
      Virtual Environments (VE s) are seen as having great potential for teaching people with autism. This paper looks at research being carried out as part of the AS Interactive project to teach social skills to adults with ...
    • Scaffolding-based Segmentation of Coronary Vascular Structures 

      Bartz, Dirk; Lakare, Sarang (The Eurographics Association, 2005)
      The coronary arteries are essential for the proper function of the human heart. However, they are generally difficult to segment in volume datasets separately from the other blood-filled cavities of the heart. The major ...
    • Scalability of Non-Rigid 3D Shape Retrieval 

      Sipiran, I.; Bustos, B.; Schreck, T.; Bronstein, A. M.; Bronstein, M.; Castellani, U.; Choi, S.; Lai, L.; Li, H.; Litman, R.; Sun, L. (The Eurographics Association, 2015)
      Due to recent advances in 3D acquisition and modeling, increasingly large amounts of 3D shape data become available in many application domains. This rises not only the need for effective methods for 3D shape retrieval, ...
