    • Dynamic Sampling and Rendering of Algebraic Point Set Surfaces 

      Guennebaud, Gael; Germann, Marcel; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Algebraic Point Set Surfaces (APSS) define a smooth surface from a set of points using local moving least-squares (MLS) fitting of algebraic spheres. In this paper we first revisit the spherical fitting problem and provide ...
    • Accurate Shadows by Depth Complexity Sampling 

      Forest, Vincent; Barthe, Loic; Paulin, Mathias (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      The accurate generation of soft shadows is a particularly computationally intensive task. In order to reduce rendering time, most real-time and offline applications decorrelate the generation of shadows from the computation ...
    • 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 ...
    • High-Resolution Volumetric Computation of Offset Surfaces with Feature Preservation 

      Pavic, Darko; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a new algorithm for the efficient and reliable generation of offset surfaces for polygonal meshes. The algorithm is robust with respect to degenerate configurations and computes (self-)intersection free offsets ...
    • 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 ...
    • Image-based Material Weathering 

      Xuey, Su; Wang, Jiaping; Tong, Xin; Dai, Qionghai; Guo, Baining (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      The appearance manifold [WTL*06] is an efficient approach for modeling and editing time-variant appearance of materials from the BRDF data captured at single time instance. However, this method is difficult to apply in ...
    • Distortion-Free Steganography for Polygonal Meshes 

      Bogomjakov, Alexander; Gotsman, Craig; Isenburg, Martin (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a technique for steganography in polygonal meshes. Our method hides a message in the indexed rep-resentation of a mesh by permuting the order in which faces and vertices are stored. The permutation is relative ...
    • Image-based Shaving 

      Nguyen, Minh Hoai; Lalonde, Jean-Francois; Efros, Alexei A.; De la Torre, Fernando (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Many categories of objects, such as human faces, can be naturally viewed as a composition of several different layers. For example, a bearded face with glasses can be decomposed into three layers: a layer for glasses, a ...
    • Hardware-Accelerated, High-Quality Rendering Based on Trivariate Splines Approximating Volume Data 

      Kalbe, Thomas; Zeilfelder, Frank (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We develop an approach for hardware-accelerated, high-quality rendering of volume data using trivariate splines. The proposed quasi-interpolating schemes are realtime reconstructions. The low total degrees provide several ...
    • Zippy: A Framework for Computation and Visualization on a GPU Cluster 

      Fan, Zhe; Qiu, Feng; Kaufman, Arie E. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Due to its high performance/cost ratio, a GPU cluster is an attractive platform for large scale general-purpose computation and visualization applications. However, the programming model for high performance general-purpose ...
    • 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 ...
    • Ray Casting Algebraic Surfaces using the Frustum Form 

      Reimers, Martin; Seland, Johan (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We propose an algorithm for interactive ray-casting of algebraic surfaces of high degree. A key point of our approach is a polynomial form adapted to the view frustum. This so called frustum form yields simple expressions ...
    • 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 ...
    • 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. ...
    • Real-Time Rendering and Editing of Vector-based Terrains 

      Bruneton, Eric; Neyret, Fabrice (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a method to populate very large terrains with very detailed features such as roads, rivers, lakes and fields. These features can be interactively edited, and the landscape can be explored in real time at any ...

    • Expressive Facial Gestures From Motion Capture Data 

      Ju, Eunjung; Lee, Jehee (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Human facial gestures often exhibit such natural stochastic variations as how often the eyes blink, how often the eyebrows and the nose twitch, and how the head moves while speaking. The stochastic movements of facial ...
