    • Automatic Multi-view Surface Matching 

      Fantoni, Simone; Castellani, Umberto; Fusiello, Andrea (The Eurographics Association, 2012)
      In this paper we tackle the problem of automatically aligning an unordered set of range views. We propose a full pipeline that goes from the scans to the complete 3D model. The emphasis is on the automation no manual ...
    • Incoherent Ray Tracing without Acceleration Structures 

      Áfra, Attila T. (The Eurographics Association, 2012)
      Recently, a new family of dynamic ray tracing algorithms, called divide-and-conquer ray tracing, has been introduced. This approach partitions the primitives on-the-fly during ray traversal, which eliminates the need for ...
    • Hyperplane Culling for Stochastic Rasterization 

      Munkberg, Jacob; Akenine-Möller, Tomas (The Eurographics Association, 2012)
      We present two novel culling tests for rasterization of simultaneous depth of field and motion blur. These tests efficiently reduce the set of xyuvt samples that need to be coverage tested within a screen space tile. The ...
    • Automatic Line Handles for Freeform Deformation 

      Schemali, Leïla; Thiery, Jean-Marc; Boubekeur, Tamy (The Eurographics Association, 2012)
      Interactive freeform surface deformation methods allow to explore the space of possible shapes using simple control structures. While recent advances in variational editing provide high quality deformations, designing ...
    • Steady State Stokes Flow Interpolation for Fluid Control 

      Bhatacharya, Haimasree; Nielsen, Michael B.; Bridson, Robert (The Eurographics Association, 2012)
      Fluid control methods often require surface velocities interpolated throughout the interior of a shape to use the velocity as a feedback force or as a boundary condition. Prior methods for interpolation in computer graphics ...
    • Efficient Evaluation of Semi-Smooth Creases in Catmull-Clark Subdivision Surfaces 

      Nießner, Matthias; Loop, Charles; Greiner, Günther (The Eurographics Association, 2012)
      We present a novel method to evaluate semi-smooth creases in Catmull-Clark subdivision surfaces. Our algorithm supports both integer and fractional crease tags corresponding to the RenderMan (Pixar) specification. In order ...
    • S-buffer: Sparsity-aware Multi-fragment Rendering 

      Vasilakis, Andreas A.; Fudos, Ioannis (The Eurographics Association, 2012)
      This work introduces S-buffer, an efficient and memory-friendly gpu-accelerated A-buffer architecture for multifragment rendering. Memory is organized into variable contiguous regions for each pixel, thus avoiding limitations ...
    • Image-based Animation of Clothes 

      Hilsmann, Anna; Eisert, Peter (The Eurographics Association, 2012)
      We propose a pose-dependent image-based rendering approach for the visualization of clothes with very high rendering quality. Our representation combines body-pose-dependent geometry and appearance. A geometric model ...
    • Forward+: Bringing Deferred Lighting to the Next Level 

      Harada, Takahiro; McKee, Jay; Yang, Jason C. (The Eurographics Association, 2012)
      This paper presents Forward+, a method of rendering many lights by culling and storing only lights that contribute to the pixel. Forward+ is an extension to traditional forward rendering. Light culling, implemented using ...
    • Fast Response and Quick Progressive Transitions using Body Part Motion Graphs 

      Fernández-Baena, Adso; Miralles, David (The Eurographics Association, 2012)
      Interactive applications where 3D character animation plays an important role need avatars ready to perform different activities. This objective has been accomplished in different works [LCR*02] [ZS09] that look for ...
    • Perceptually Based Afterimage Synthesis 

      Mikamo, Michihiro; Slomp, Marcos; Raytchev, Bisser; Tamaki, Toru; Kaneda, Kazufumi (The Eurographics Association, 2012)
      Afterimages comprise a common, recurring perceptual phenomenon experienced in a daily-basis. Afterimages are best realized when staring at some high intensity light source (i.e., a light bulb) and then shifting the ocular ...
    • Geometric Details on Skeleton-based Implicit Surfaces 

      Zanni, Cedric; Bares, P.; Lagae, Ares; Quiblier, M.; Cani, Marie-Paule (The Eurographics Association, 2012)
      We present a modeling technique to enhance implicit surfaces with procedural geometric details. The details are based on Gabor noise, which enables us to seamlessly handle anisotropy. The orientation of details can be ...
    • FTLE Computation Beyond First-Order Approximation 

      Üffinger, Markus; Sadlo, Filip; Kirby, Mike; Hansen, Charles; Ertl, Thomas (The Eurographics Association, 2012)
      We present a framework for different approaches to finite-time Lyapunov exponent (FTLE) computation for 2D vector fields, based on the advection of seeding circles. On the one hand it unifies the popular flow map approach ...
    • Hybrid CPU/GPU KD-Tree Construction for Versatile Ray Tracing 

      Roccia, Jean-Patrick; Paulin, Mathias; Coustet, Christophe (The Eurographics Association, 2012)
      We propose an hybrid CPU-GPU ray-tracing implementation based on an optimal Kd-Tree as acceleration structure. The construction and traversal of this KD-tree takes benefit from both the CPU and the GPU to achieve ...
    • Improved Obstacle Relevancy, Distance, and Angle for Crowds Constrained to Arbitrary Manifolds in 3D Space 

      Ricks, Brian C.; Egbert, Parris K. (The Eurographics Association, 2012)
      Recent work has proposed crowd simulation algorithms on arbitrary manifolds in 3D space. These algorithms simulate crowds on far more realistic surfaces than previously possible, including multi-story structures, science ...

      Guggeri, Fabio; Scateni, Riccardo; Pajarola, Renato (The Eurographics Association, 2012)
      Shape reconstruction from raw point sets is a hot research topic. Point sets are increasingly available as primary input source, since low-cost acquisition methods are largely accessible nowadays, and these sets are more ...
