    • SAFE: Structure-aware Facade Editing 

      Dang, Minh; Ceylan, Duygu; Neubert, Boris; Pauly, Mark (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Many man-made objects, in particular building facades, exhibit dominant structural relations such as symmetry and regularity. When editing these shapes, a common objective is to preserve these relations. However, often ...

    • 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 Guided Spatial Split Partitioning for Fast BVH Construction 

      Ganestam, Per; Doggett, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a new SAH guided approach to subdividing triangles as the scene is coarsely partitioned into smaller sets of spatially coherent triangles. Our triangle split approach is integrated into the partitioning stage ...

    • 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 ...

    • Saliency-aware Real-time Volumetric Fusion for Object Reconstruction 

      Yang, Sheng; Chen, Kang; Liu, Minghua; Fu, Hongbo; Hu, Shi-Min (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a real-time approach for acquiring 3D objects with high fidelity using hand-held consumer-level RGB-D scanning devices. Existing real-time reconstruction methods typically do not take the point of interest into ...

    • Saliency‐Preserving Slicing Optimization for Effective 3D Printing 

      Wang, Weiming; Chao, Haiyuan; Tong, Jing; Yang, Zhouwang; Tong, Xin; Li, Hang; Liu, Xiuping; Liu, Ligang (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present an adaptive slicing scheme for reducing the manufacturing time for 3D printing systems. Based on a new saliency‐based metric, our method optimizes the thicknesses of slicing layers to save printing time and ...

    • 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 ...

    • Sample Elimination for Generating Poisson Disk Sample Sets 

      Yuksel, Cem (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      In this paper we describe sample elimination for generating Poisson disk sample sets with a desired size. We introduce a greedy sample elimination algorithm that assigns a weight to each sample in a given set and eliminates ...

    • Sample‐Based Manifold Filtering for Interactive Global Illumination and Depth of Field 

      Bauszat, P.; Eisemann, M.; John, S.; Magnor, M. (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present a fast reconstruction filtering method for images generated with Monte Carlo–based rendering techniques. Our approach specializes in reducing global illumination noise in the presence of depth‐of‐field effects ...

    • Sampling and Anti-Aliasing of Discrete 3-D Volume Density Textures 

      Sakas, Georgios; Gerth, Matthias (Eurographics Association, 1991)
      In recent years, a number of techniques have been developed for rendering volume effects (haze, fog, smoke, clouds, etc.) in order to enhance reality in computer-generated imagery as well as to improve the performance of ...

    • Sampling from Quadric-Based CSG Surfaces 

      Trettner, Philip; Kobbelt, Leif (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      We present an efficient method to create samples directly on surfaces defined by constructive solid geometry (CSG) trees or graphs. The generated samples can be used for visualization or as an approximation to the actual ...

    • Sampling Visible GGX Normals with Spherical Caps 

      Dupuy, Jonathan; Benyoub, Anis (The Eurographics Association and John Wiley & Sons Ltd., 2023)
      Importance sampling the distribution of visible GGX normals requires sampling those of a hemisphere. In this work, we introduce a novel method for sampling such visible normals. Our method builds upon the insight that a ...

    • SAR: Stroke Authorship Recognition 

      Shaheen, Sara; Rockwood, Alyn; Ghanem, Bernard (Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Are simple strokes unique to the artist or designer who renders them? If so, can this idea be used to identify authorship or to classify artistic drawings? Also, could training methods be devised to develop particular ...
