    • Temporally Coherent and Artistically Intended Stylization of Feature Lines Extracted from 3D Models 

      Cardona, Luis; Saito, Suguru (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      In this paper, we propose a method to maintain the temporal coherence of stylized feature lines extracted from 3D models and preserve an artistically intended stylization provided by the user. We formally define the problem ...
    • Tracing Field-Coherent Quad Layouts 

      Pietroni, Nico; Puppo, Enrico; Marcias, Giorgio; Scopigno, Roberto; Cignoni, Paolo (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Given a cross field over a triangulated surface we present a practical and robust method to compute a field aligned coarse quad layout over the surface. The method works directly on a triangle mesh without requiring any ...
    • Trip Synopsis: 60km in 60sec 

      Huang, Hui; Lischinski, Dani; Hao, Zhuming; Gong, Minglun; Christie, Marc; Cohen-Or, Daniel (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Computerized route planning tools are widely used today by travelers all around the globe, while 3D terrain and urban models are becoming increasingly elaborate and abundant. This makes it feasible to generate a virtual ...
    • TSS BVHs: Tetrahedron Swept Sphere BVHs for Ray Tracing Subdivision Surfaces 

      Du, Peng; Kim, Yong-Jun; Yoon, Sung Eui (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a novel, compact bounding volume hierarchy, TSS BVH, for ray tracing subdivision surfaces computed by the Catmull-Clark scheme. We use Tetrahedron Swept Sphere (TSS) as a bounding volume to tightly bound limit ...
    • Variance Analysis of Multi-sample and One-sample Multiple Importance Sampling 

      Sbert, Mateu; Havran, Vlastimil; Szirmay-Kalos, Laszlo (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We reexamine in this paper the variance for the Multiple Importance Sampling (MIS) estimator for multi-sample and onesample model. As a result of our analysis we can obtain the optimal estimator for the multi-sample model ...
    • Visual Contrast Sensitivity and Discrimination for 3D Meshes and their Applications 

      Nader, Georges; Wang, Kai; Hétroy-Wheeler, Franck; Dupont, Florent (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      In this paper, we first introduce an algorithm for estimating the visual contrast on a 3D mesh. We then perform a series of psychophysical experiments to study the effects of contrast sensitivity and contrast discrimination ...
