    • Component-wise Controllers for Structure-Preserving Shape Manipulation 

      Zheng, Youyi; Fu, Hongbo; Cohen-Or, Daniel; Au, Oscar Kin-Chung; Tai, Chiew-Lan (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Recent shape editing techniques, especially for man-made models, have gradually shifted focus from maintaining local, low-level geometric features to preserving structural, high-level characteristics like symmetry and ...
    • Guided ProceduralModeling 

      Bene , Bedrich; tava, Ondrej; Mech, Radomir; Miller, Gavin (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Procedural methods present one of the most powerful techniques for authoring a vast variety of computer graphics models. However, their massive applicability is hindered by the lack of control and a low predictability of ...
    • Learning Line Features in 3D Geometry 

      Sunkel, Martin; Jansen, Silke; Wand, Michael; Eisemann, Elmar; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Feature detection in geometric datasets is a fundamental tool for solving shape matching problems such as partial symmetry detection. Traditional techniques usually employ a priori models such as crease lines that are ...
    • Hatching for Motion Picture Production 

      Umenhoffer, Tamás; Szécsi, László; Szirmay-Kalos, László (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      This paper presents a hatching algorithm which - while also allows for an implementation in real-time - is integrated into the production pipeline of computer generated motion picture. Motion picture production pipelines ...
    • Comprehensive Facial Performance Capture 

      Fyffe, Graham; Hawkins, Tim; Watts, Chris; Ma, Wan-Chun; Debevec, Paul (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We present a system for recording a live dynamic facial performance, capturing highly detailed geometry and spatially varying diffuse and specular reflectance information for each frame of the performance. The result is a ...
    • Shape Analysis with Subspace Symmetries 

      Berner, Alexander; Wand, Michael; Mitra, Niloy J.; Mewes, Daniel; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We address the problem of partial symmetry detection, i.e., the identification of building blocks a complex shape is composed of. Previous techniques identify parts that relate to each other by simple rigid mappings, ...
    • A Sparse Parametric Mixture Model for BTF Compression, Editing and Rendering 

      Wu, Hongzhi; Dorsey, Julie; Rushmeier, Holly (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Bidirectional texture functions (BTFs) represent the appearance of complex materials. Three major shortcomings with BTFs are the bulky storage, the difficulty in editing and the lack of efficient rendering methods. To ...
    • Goal-based Caustics 

      Papas, Marios; Jarosz, Wojciech; Jakob, Wenzel; Rusinkiewicz, Szymon; Matusik, Wojciech; Weyrich, Tim (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We propose a novel system for designing and manufacturing surfaces that produce desired caustic images when illuminated by a light source. Our system is based on a nonnegative image decomposition using a set of possibly ...
    • Paint Mesh Cutting 

      Fan, Lubin; Liu, Ligang; Liu, Kun (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We present a novel progressive painting-based mesh cut out tool, called Paint Mesh Cutting, for interactive mesh segmentation. Different from the previous user interfaces, the user only needs to draw a single stroke on the ...
    • Contouring Discrete Indicator Functions 

      Manson, Josiah; Smith, Jason; Schaefer, Scott (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We present a method for calculating the boundary of objects from Discrete Indicator Functions that store 2- material volume fractions with a high degree of accuracy. Although Marching Cubes and its derivatives are effective ...
    • Procedural Modeling of Interconnected Structures 

      Krecklau, Lars; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      The complexity and detail of geometric scenes that are used in today's computer animated films and interactive games have reached a level where the manual creation by traditional 3D modeling tools has become infeasible. ...
    • Intrinsic Shape Matching by Planned Landmark Sampling 

      Tevs, Art; Berner, Alexander; Wand, Michael; Ihrke, Ivo; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Recently, the problem of intrinsic shape matching has received a lot of attention. A number of algorithms have been proposed, among which random-sampling-based techniques have been particularly successful due to their ...
    • Dynamic Display of BRDFs 

      Hullin, Matthias B.; Lensch, Hendrik P. A.; Raskar, Ramesh; Seidel, Hans-Peter; Ihrke, Ivo (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      This paper deals with the challenge of physically displaying reflectance, i.e., the appearance of a surface and its variation with the observer position and the illuminating environment. This is commonly described by the ...
    • Blur-Aware Image Downsampling 

      Trentacoste, Matthew; Mantiuk, Rafal; Heidrich, Wolfgang (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Resizing to a lower resolution can alter the appearance of an image. In particular, downsampling an image causes blurred regions to appear sharper. It is useful at times to create a downsampled version of the image that ...
    • GeoBrush: Interactive Mesh Geometry Cloning 

      Takayama, Kenshi; Schmidt, Ryan; Singh, Karan; Igarashi, Takeo; Boubekeur, Tamy; Sorkine, Olga (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We propose a method for interactive cloning of 3D surface geometry using a paintbrush interface, similar to the continuous cloning brush popular in image editing. Existing interactive mesh composition tools focus on atomic ...
    • Image Retargeting Quality Assessment 

      Liu, Yong-Jin; Luo, Xi; Xuan, Yu-Ming; Chen, Wen-Feng; Fu, Xiao-Lan (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Content-aware image retargeting is a technique that can flexibly display images with different aspect ratios and simultaneously preserve salient regions in images. Recently many image retargeting techniques have been ...
