    • SPH Granular Flow with Friction and Cohesion 

      Alduán, Iván; Otaduy, Miguel A. (The Eurographics Association, 2011)
      Combining mechanical properties of solids and fluids, granular materials pose important challenges for the design of algorithms for realistic animation. In this paper, we present a simulation algorithm based on smoothed ...
    • Spherical Barycentric Coordinates 

      Langer, Torsten; Belyaev, Alexander; Seidel, Hans-Peter (The Eurographics Association, 2006)
      We develop spherical barycentric coordinates. Analogous to classical, planar barycentric coordinates that describe the positions of points in a plane with respect to the vertices of a given planar polygon, spherical ...
    • Spherical Blue Noise 

      Wong, Kin-Ming; Wong, Tien-Tsin (The Eurographics Association, 2018)
      We present a physically based method which generates unstructured uniform point set directly on the S2-sphere. Spherical uniform point sets are useful for illumination sampling in Quasi Monte Carlo (QMC) rendering but it ...
    • Spherical Fibonacci Point Sets for Illumination Integrals 

      Marques, R.; Bouville, C.; Ribardière, M.; Santos, L. P.; Bouatouch, K. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Quasi-Monte Carlo (QMC) methods exhibit a faster convergence rate than that of classic Monte Carlo methods. This feature has made QMC prevalent in image synthesis, where it is frequently used for approximating the value ...
    • Spherical Gaussian Light-field Textures for Fast Precomputed Global Illumination 

      Currius, Roc Ramon; Dolonius, Dan; Assarsson, Ulf; Sintorn, Erik (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      We describe a method to use Spherical Gaussians with free directions and arbitrary sharpness and amplitude to approximate the precomputed local light field for any point on a surface in a scene. This allows for a high-quality ...
    • Spherical Gaussian‐based Lightcuts for Glossy Interreflections 

      Huo, Y.C.; Jin, S.H.; Liu, T.; Hua, W.; Wang, R.; Bao, H.J. (© 2020 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2020)
      It is still challenging to render directional but non‐specular reflections in complex scenes. The SG‐based (Spherical Gaussian) many‐light framework provides a scalable solution but still requires a large number of glossy ...
    • Spherical Harmonic Gradients for Mid-Range Illumination 

      Annen, Thomas; Kautz, Jan; Durand, Frédo; Seidel, Hans-Peter (The Eurographics Association, 2004)
      Spherical harmonics are often used for compact description of incident radiance in low-frequency but distant lighting environments. For interaction with nearby emitters, computing the incident radiance at the center of an ...
    • Spherical Harmonic Lighting of Wavelength-Dependent Phenomena 

      Lindsay, Clifford; Agu, Emmanuel (The Eurographics Association, 2005)
      Rendering of objects that exhibit iridescence has previously been limited to simple lighting conditions generated from a few point or directional lights. We extend this idea by modeling light interference as a Bidirectional ...
    • Spherical Parametric Measurement for Continuous and Balanced Mesh Segmentation 

      Zhang, Huadong; Cao, Lizhou; Peng, Chao (The Eurographics Association, 2023)
      Mesh segmentation is an important process for building the discrete mesh structure used on the GPU to accelerate geometry processing applications. In this paper, we introduce a novel mesh segmentation method that creates ...
    • Spherical Q2-tree for Sampling Dynamic Environment Sequences 

      Wan, Liang; Wong, Tien-Tsin; Leung, Chi-Sing (The Eurographics Association, 2005)
      Previous methods in environment map sampling seldom consider a sequence of dynamic environment maps. The generated sampling patterns of the sequence may not maintain the temporal illumination consistency and result in ...
    • Spherical Triangular B-splines with Application to Data Fitting 

      Pfeifle, Ron; Seidel, Hans-Peter (Blackwell Science Ltd and the Eurographics Association, 1995)
      Triangular B-splines surfaces are a tool for representing arbitrary piecewise polynomial surfaces over planar triangulations, while automatically maintaining continuity properties across patch boundaries. Recently, Alfeld ...
    • Spherical Visibility Sampling 

      Eikel, Benjamin; Jähn, Claudius; Fischer, Matthias; Heide, Friedhelm Meyer auf der (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Many 3D scenes (e.g. generated from CAD data) are composed of a multitude of objects that are nested in each other. A showroom, for instance, may contain multiple cars and every car has a gearbox with many gearwheels located ...
    • SPIDER: SPherical Indoor DEpth Renderer 

      Tukur, Muhammad; Pintore, Giovanni; Gobbetti, Enrico; Schneider, Jens; Agus, Marco (The Eurographics Association, 2022)
      Today's Extended Reality (XR) applications that call for specific Diminished Reality (DR) strategies to hide specific classes of objects are increasingly using 360? cameras, which can capture entire areas in a single ...
    • Spinnstube: A Seated Augmented Reality Display System 

      Wind, Jürgen; Riege, Kai; Bogen, Manfred (The Eurographics Association, 2007)
      We describe the Spinnstube, a new projection-based Augmented Reality display system for collaborative work environments. By simply attaching the system to a desk, real objects are augmented with virtual objects by using a ...
    • Spinoff - Transferring Energy between Real and Virtual Worlds 

      Groenegress, Christoph; Slater, Mel; Tamke, Martin; Thomsen, Mette Ramsgard (The Eurographics Association, 2007)
      There is a widening gap between interaction devices for Virtual Environments and other factors such as graphical realism, accessibility and complexity. To address this problem, we developed a Mixed Reality environment that ...
