    • 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)
      We present a method for tuning primal stationary subdivision schemes to give the best possible behaviour near extraordinary vertices with respect to curvature variation.Current schemes lead to a limit surface around ...

    • 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 ...

    • Wrinkling Coarse Meshes on the GPU 

      Loviscach, J. (The Eurographics Association and Blackwell Publishing, Inc, 2006)
      The simulation of complex layers of folds of cloth can be handled through algorithms which take the physical dynamics into account. In many cases, however, it is sufficient to generate wrinkles on a piece of garment which ...
