    • A Predictive Light Transport Model for the Human Iris 

      W.Y. Lam, Michael; V.G. Baranoski, Gladimir (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      Recently, light interactions with organic matter have become the object of detailed investigations by image synthesis researchers. Besides allowing these materials to be rendered in a more intuitive manner, these efforts ...
    • Preface 

      Unknown author (The Eurographics Association and Blackwell Publishing, Inc, 2006)
    • A Primer on Topological Persistence 

      Edelsbrunner, Herbert (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      The idea of topological persistence is to look at homological features that persist along a nested sequence of topo-logical spaces. As a typical example, we may take the sequence of sublevel sets of a function. The ...
    • Projective Alpha Colour 

      Willis, Philip (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      Alpha colours were introduced for image compositing, using a pixel coverage model. Algebraically they resemble homogeneous coordinates, widely used in projective geometry calculations. We show why this is the case. This ...
    • Ray Tracing Animated Scenes using Motion Decomposition 

      Guenther, Johannes; Friedrich, Heiko; Wald, Ingo; Seidel, Hans-Peter; Slusallek, Philipp (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      Though ray tracing has recently become interactive, its high precomputation time for building spatial indices usually limits its applications to walkthroughs of static scenes. This is a major limitation, as most applications ...
    • Real-Time Weighted Pose-Space Deformation on the GPU 

      Rhee, Taehyun; Lewis, J.P.; Neumann, Ulrich (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      WPSD (Weighted Pose Space Deformation) is an example based skinning method for articulated body animation. The per-vertex computation required in WPSD can be parallelized in a SIMD (Single Instruction Multiple Data) manner ...
    • Reflected-Scene Impostors for Realistic Reflections at Interactive Rates 

      Popescu, Voicu; Mei, Chunhui; Dauble, Jordan; Sacks, Elisha (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      We present a technique for rendering reflections on complex reflectors at interactive rates based on approximating the geometry of the reflected scene with impostors. The reflections correctly convey the distance to the ...
    • A Robust Two-Step Procedure for Quad-Dominant Remeshing 

      Marinov, Martin; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      We propose a new technique for quad-dominant remeshing which separates the local regularity requirements from the global alignment requirements by working in two steps. In the first step, we apply a slight variant of ...
    • Seamless Integration of Initial Sketching and Subsequent Detail Editing in Flower Modeling 

      Ijiri, T.; Owada, S.; Igarashi, T. (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      We present an interactive modeling system for flower composition that supports seamless transformation from an initial sketch to a detailed three-dimensional (3D) model. To begin, the user quickly sketches the overall ...
    • Semantic Photo Synthesis 

      Johnson, M.; Brostow, G. J.; Shotton, J.; Arandjelovic, O.; Kwatra, V.; Cipolla, R. (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      Composite images are synthesized from existing photographs by artists who make concept art, e.g., storyboards for movies or architectural planning. Current techniques allow an artist to fabricate such an image by digitally ...
    • Silhouette Extraction in Hough Space 

      Olson, Matt; Zhang , Hao (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      Object-space silhouette extraction is an important problem in fields ranging from non-photorealistic computer graphics to medical robotics. We present an efficient silhouette extractor for triangle meshes under perspective ...
    • Splicing Upper-Body Actions with Locomotion 

      Heck, Rachel; Kovar, Lucas; Gleicher, Michael (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      This paper presents a simple and efficient technique for synthesizing high-fidelity motions by attaching, or splicing, the upper-body action of one motion example to the lower-body locomotion of another. Existing splicing ...
    • Stroke Pattern Analysis and Synthesis 

      Barla, Pascal; Breslav, Simon; Thollot, Joelle; Sillion, Francois; Markosian, Lee (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      We present a synthesis technique that can automatically generate stroke patterns based on a user-specified reference pattern. Our method is an extension of texture synthesis techniques to vector-based patterns. Such an ...
    • Sweep-based Freeform Deformations 

      Yoon, Seung-Hyun; Kim, Myung-Soo (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      We propose a sweep-based approach to the freeform deformation of three-dimensional objects. Instead of using a volume enclosing the whole object, we approximate only its deformable parts using sweep surfaces. The vertices ...
    • Texture Adaptation for Progressive Meshes 

      Chen, Chih-Chun; Chuang, Jung-Hong (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      Level-of-detail modeling is a vital representation for real-time applications. To support texture mapping progressive meshes (PM), we usually allow the whole PM sequence to share a common texture map. Although such a common ...
    • Topological Structures in Two-Parameter-Dependent 2D Vector Fields 

      Weinkauf, T.; Theisel, H.; Hege, H.-C.; Seidel, H.-P. (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      In this paper we extract and visualize the topological skeleton of two-parameter-dependent vector fields. This kind of vector data depends on two parameter dimensions, for instance physical time and a scale parameter. We ...
    • Towards a Unified Dynamical Solver for Computer Graphics 

      Stam, Jos (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      In this talk I will present some research I have done over the past few years in developing a unified dynamical solver for computer graphics. Currently many solvers are specialized for a given phenomenon such as fluid flow, ...
    • Tuning Subdivision by Minimising Gaussian Curvature Variation Near Extraordinary Vertices 

      Augsdoerfer, U.H.; Dodgson, N.A.; Sabin, M.A. (The Eurographics Association and Blackwell Publishing, Inc, 2006)

    • Virtual Garments: A Fully Geometric Approach for Clothing Design 

      Decaudin, Philippe; Julius, Dan; Wither, Jamie; Boissieux, Laurence; Sheffer, Alla; Cani, Marie-Paule (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      Modeling dressed characters is known as a very tedious process. It usually requires specifying 2D fabric patterns, positioning and assembling the min 3D, and then performing a physically-based simulation. The latter accounts ...
    • Volume-Surface Trees 

      Boubekeur, Tamy; Heidrich, Wolfgang; Granier, Xavier; Schlick, Christophe (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      Many algorithms in computer graphics improve their efficiency by using Hierarchical Space Subdivision Schemes (HS3), such as octrees, kD-trees or BSP trees. Such HS3 usually provide an axis-aligned subdivision of the 3D ...
