    • 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 ...

    • The Shadow Meets the Mask: Pyramid-Based Shadow Removal 

      Shor, Yael; Lischinski, Dani (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper we propose a novel method for detecting and removing shadows from a single image thereby obtaining a high-quality shadow-free image. With minimal user assistance, we first identify shadowed and lit areas on ...

    • Shadowed Relighting of Dynamic Geometry with 1D BRDFs 

      Nowrouzezahrai, Derek; Kalogerakis, Evangelos; Simari, Patricio; Fiume, Eugene (The Eurographics Association, 2008)
      We present a method for synthesizing the dynamic self-occlusion of an articulating character in real-time (> 170Hz) while incorporating reflection effects from 1D BRDFs under dynamic lighting and view conditions. We ...

    • Simulation of Human Motion Data using Short-Horizon Model-Predictive Control 

      Da Silva, M.; Abe, Y.; Popovic, J. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Many data-driven animation techniques are capable of producing high quality motions of human characters. Few techniques, however, are capable of generating motions that are consistent with physically simulated environments. ...

    • 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 ...

    • Sketch-Based Procedural Surface Modeling and Compositing Using Surface Trees 

      Schmidt, Ryan; Singh, Karan (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a system for creating and manipulating layered procedural surface editing operations, which is motivated by the limited support for iterative design in free-form modeling. A combination of sketch-based and ...

    • Sketching and Composing Widgets for 3D Manipulation 

      Schmidt, Ryan; Singh, Karan; Balakrishnan, Ravin (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present an interface for 3D object manipulation in which standard transformation tools are replaced with transient 3D widgets invoked by sketching context-dependent strokes. The widgets are automatically aligned to axes ...

    • Sparse points matching by combining 3D mesh saliency with statistical descriptors 

      Castellani, U.; Cristani, M.; Fantoni, S.; Murino, V. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper proposes new methodology for the detection and matching of salient points over several views of an object. The process is composed by three main phases. In the first step, detection is carried out by adopting a ...

    • Spectral Geometry Processing with Manifold Harmonics 

      Vallet, B.; Levy, B. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present an explicit method to compute a generalization of the Fourier Transform on a mesh. It is well known that the eigenfunctions of the Laplace Beltrami operator (Manifold Harmonics) define a function basis allowing ...

    • Stereo Light Probe 

      Corsini, Massimiliano; Callieri, Marco; Cignoni, Paolo (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper we present a practical, simple and robust method to acquire the spatially-varying illumination of a real-world scene. The basic idea of the proposed method is to acquire the radiance distribution of the scene ...

    • Surface Reconstruction From Non-parallel Curve Networks 

      Liu, L.; Bajaj, C.; Deasy, J. O.; Low, D. A.; Ju, T. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Building surfaces from cross-section curves has wide applications including bio-medical modeling. Previous work in this area has mostly focused on connecting simple closed curves on parallel cross-sections. Here we consider ...

    • A Taxonomy of Modeling Techniques using Sketch-Based Interfaces 

      Olsen, L.; Samavati, F. F.; Sousa, M. Costa; Jorge, J. (The Eurographics Association, 2008)
      Traditional user interfaces in modeling have followed the WIMP (Window, Icon, Menu, Pointer) paradigm. While functional and powerful, they can also be cumbersome and daunting to a novice user; creating a complex model ...

    • Teaching Soft-skills: Digital Game Development in a Multi-Discipline Environment 

      Diefenbach, Paul J. (The Eurographics Association, 2008)
      While academic video game development has garnered widespread publicity due to the size of the industry and the potential impact on faltering Computer Science enrollment, many academic programs fail to address the expansive ...

    • 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 ...

    • Theory and Methods of Light-Field Photography 

      Georgiev, Todor; Lumsdaine, Andrew (The Eurographics Association, 2008)
      Computational photography is based on capturing and processing discrete representations of all the light rays in the 3D space. Compared to conventional photography, which captures 2D images, computational photography ...

    • Transparent and Specular Object Reconstruction 

      Ihrke, Ivo; Kutulakos, Kiriakos N.; Lensch, Hendrik P. A.; Magnor, Marcus; Heidrich, Wolfgang (The Eurographics Association, 2008)
