    • SpringLens Distributed Nonlinear Magnifications 

      Germer, T.; Götzelmann, T.; Spindler, M.; Strothotte, Th. (The Eurographics Association, 2006)
      We present a flexible, distributed and effective technique to model custom distortions of images. The main idea is to use a mass-spring model to create a flexible surface and to create distortions by changing the rest-lengths. ...

    • SQuad: Compact Representation for Triangle Meshes 

      Gurung, Topraj; Laney, Daniel; Lindstrom, Peter; Rossignac, Jarek (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      The SQuad data structure represents the connectivity of a triangle mesh by its "S table" of about 2 rpt (integer references per triangle). Yet it allows for a simple implementation of expected constant-time, random-access ...

    • SRDH: Specializing BVH Construction and Traversal Order Using Representative Shadow Ray Sets 

      Feltman, Nicolas; Lee, Minjae; Fatahalian, Kayvon (The Eurographics Association, 2012)
      We derive the Shadow Ray Distribution Heuristic (SRDH), an accurate cost estimator for shadow ray traversal through a bounding volume hierarchy (BVH). The SRDH leverages up-front knowledge of the distribution and intersection ...

    • SREC‐RT: A Structure for Ray Tracing Rounded Edges and Corners 

      Courtin, Simon; Ribardière, Mickael; Horna, Sebastien; Poulin, Pierre; Meneveaux, Daniel (© 2021 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2021)
      Man‐made objects commonly exhibit rounded edges and corners generated through their manufacturing processes. The variation of surface normals at these confined locations produces shading details that are visually essential ...

    • SRF-Net: Spatial Relationship Feature Network for Tooth Point Cloud Classification 

      Ma, Qian; Wei, Guangshun; Zhou, Yuanfeng; Pan, Xiao; Xin, Shiqing; Wang, Wenping (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      3D scanned point cloud data of teeth is popular used in digital orthodontics. The classification and semantic labelling for point cloud of each tooth is a key and challenging task for planning dental treatment. Utilizing ...

    • SRNet: A 3D Scene Recognition Network using Static Graph and Dense Semantic Fusion 

      Fan, Zhaoxin; Liu, Hongyan; He, Jun; Sun, Qi; Du, Xiaoyong (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Point cloud based 3D scene recognition is fundamental to many real world applications such as Simultaneous Localization and Mapping (SLAM). However, most of existing methods do not take full advantage of the contextual ...

    • SS-SfP: Neural Inverse Rendering for Self Supervised Shape from (Mixed) Polarization 

      Tiwari, Ashish; Raman, Shanmuganathan (The Eurographics Association, 2023)
      We present a novel inverse rendering-based framework to estimate the 3D shape (per-pixel surface normals and depth) of objects and scenes from single-view polarization images, the problem popularly known as Shape from ...

    • SSCA: Situated Space-time Cube Analytics 

      Alallah, Fouad; Faleel, Shariff; Sakamoto, Yumiko; Rey, Bradley; Irani, Pourang (The Eurographics Association, 2022)
      Spatio-temporal visualization research has been capturing much attention in recent years. Space-time cube (STC) has been commonly used to visualize this data to support analytic tasks. However, the current STC visualization ...

    • SSD: Smooth Signed Distance Surface Reconstruction 

      Calakli, Fatih; Taubin, Gabriel (The Eurographics Association and Blackwell Publishing Ltd., 2011)
