      Gutierrez, Diego; Seron, Francisco J.; Munoz, Adolfo; Anson, Oscar (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Simulating the in-water ocean light field is a daunting task. Ocean waters are one of the richest participating media, where light interacts not only with water molecules, but with suspended particles and organic matter ...

      Shesh, Amit; Chen, Baoquan (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper we present a pipeline for rendering dynamic 2D/3D line drawings efficiently. Our main goal is to create efficient static renditions and coherent animations of line drawings in a setting where lines can be ...
    • Photo-realistic Rendering of Metallic Car Paint from Image-Based Measurements 

      Rump, Martin; Mueller, Gero; Sarlette, Ralf; Koch, Dirk; Klein, Reinhard (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      State-of-the-art car paint shows not only interesting and subtle angular dependency but also significant spatial variation. Especially in sunlight these variations remain visible even for distances up to a few meters and ...
    • Real-Time Translucent Rendering Using GPU-based Texture Space Importance Sampling 

      Chang, Chih-Wen; Lin, Wen-Chieh; Ho, Tan-Chi; Huang, Tsung-Shian; Chuang, Jung-Hong (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a novel approach for real-time rendering of translucent surfaces. The computation of subsurface scattering is performed by first converting the integration over the 3D model surface into an integration over a ...
    • An Adaptive Contact Model for the Robust Simulation of Knots 

      Spillmann, Jonas; Teschner, Matthias (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper, we present an adaptive model for dynamically deforming hyper-elastic rods. In contrast to existing approaches, adaptively introduced control points are not governed by geometric subdivision rules. Instead, ...
    • Single-pass Scalable Subsurface Rendering with Lightcuts 

      Arbree, Adam; Walter, Bruce; Bala, Kavita (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a new, scalable, single pass algorithm for computing subsurface scattering using the diffusion approximation. Instead of pre-computing a globally conservative estimate of the surface irradiance like ...
    • A Fast Simulation Method Using Overlapping Grids for Interactions between Smoke and Rigid Objects 

      Dobashi, Yoshinori; Matsuda, Yasuhiro; Yamamoto, Tsuyoshi; Nishita, Tomoyuki (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Recently, many techniques using computational fluid dynamics have been proposed for the simulation of natural phenomena such as smoke and fire. Traditionally, a single grid is used for computing the motion of fluids. When ...
    • Fluid in Video: Augmenting Real Video with Simulated Fluids 

      Kwatra, Vivek; Mordohai, Philippos; Narain, Rahul; Penta, Sashi Kumar; Carlsonk, Mark; Pollefeys, Marc; Lin, Ming C. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a technique for coupling simulated fluid phenomena that interact with real dynamic scenes captured as a binocular video sequence. We first process the binocular video sequence to obtain a complete 3D reconstruction ...
    • A Semi-Lagrangian CIP Fluid Solver without Dimensional Splitting 

      Kim, Doyub; Song, Oh-young; Ko, Hyeong-Seok (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper, we propose a new constrained interpolation profile (CIP) method that is stable and accurate but requires less amount of computation compared to existing CIP-based solvers. CIP is a high-order fluid advection ...
    • Higher Order Barycentric Coordinates 

      Langer, Torsten; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In recent years, a wide range of generalized barycentric coordinates has been suggested. However, all of them lack control over derivatives. We show how the notion of barycentric coordinates can be extended to specify ...
    • Conformal Flattening by Curvature Prescription and Metric Scaling 

      Ben-Chen, Mirela; Gotsman, Craig; Bunin, Guy (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present an efficient method to conformally parameterize 3D mesh data sets to the plane. The idea behind our method is to concentrate all the 3D curvature at a small number of select mesh vertices, called cone singularities, ...
    • An Example-based Procedural System for Element Arrangement 

      Ijiri, Takashi; Mech, Radomir; Igarashi, Takeo; Miller, Gavin (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a method for synthesizing two dimensional (2D) element arrangements from an example. The main idea is to combine texture synthesis techniques based-on a local neighborhood comparison and procedural modeling ...
    • Manifold-valued Thin-Plate Splines with Applications in Computer Graphics 

      Steinke, Florian; Hein, Matthias; Peters, Jan; Schoelkopf, Bernhard (The Eurographics Association and Blackwell Publishing Ltd, 2008)

    • Texture Synthesis From Photographs 

      Eisenacher, C.; Lefebvre, S.; Stamminger, M. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      The goal of texture synthesis is to generate an arbitrarily large high-quality texture from a small input sample. Generally, it is assumed that the input image is given as a flat, square piece of texture, thus it has to ...
    • Floating Textures 

      Eisemann, M.; De Decker, B.; Magnor, M.; Bekaert, P.; De Aguiar, E.; Ahmed, N.; Theobalt, C.; Sellent, A. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a novel multi-view, projective texture mapping technique. While previous multi-view texturing approaches lead to blurring and ghosting artefacts if 3D geometry and/or camera calibration are imprecise, we propose ...
    • Automatic Conversion of Mesh Animations into Skeleton-based Animations 

      De Aguiar, Edilson; Theobalt, Christian; Thrun, Sebastian; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Recently, it has become increasingly popular to represent animations not by means of a classical skeleton-based model, but in the form of deforming mesh sequences. The reason for this new trend is that novel mesh deformation ...

      Pekelny, Yuri; Gotsman, Craig (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present an algorithm for acquiring the 3D surface geometry and motion of a dynamic piecewise-rigid object using a single depth video camera. The algorithm identifies and tracks the rigid components in each frame, while ...
