    • A Hidden-picture Puzzles Generator 

      Yoon, Jong-Chul; Lee, In-Kwon; Kang, Henry (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      A hidden-picture puzzle contains objects hidden in a background image, in such a way that each object fits closely into a local region of the background. Our system converts image of the background and objects into line ...
    • Interactive Global Illumination for Deformable Geometry in CUDA 

      Schmitz, Arne; Tavenrath, Markus; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Interactive global illumination for fully deformable scenes with dynamic relighting is currently a very elusive goal in the area of realistic rendering. In this work we propose a system that is based on explicit visibility ...

      A knitted animal is made of a closed surface consisting of several knitted patches knitted out of yarn and stuffed with cotton (Fig. 1). We introduce a system to create a knitting pattern from a given 3D surface model ...
    • Local Volume Preservation for Skinned Characters 

      Rohmer, Damien; Hahmann, Stefanie; Cani, Marie-Paule (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Generating plausible deformations of a character skin within the standard production pipeline is a challenge. This paper presents a volume preservation method dedicated to skinned characters. As usual, the character is ...
    • Online Personalised Non-photorealistic Rendering Technique for 3D Geometry from Incremental Sketching

      This paper presents an online personalised non-photorealistic rendering (NPR) technique for 3D models generated from interactively sketched input. This technique has been integrated into a sketch-based modelling system. ...
    • Part-type Segmentation of Articulated Voxel-Shapes using the Junction Rule 

      Reniers, Dennie; Telea, Alexandru (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a part-type segmentation method for articulated voxel-shapes based on curve skeletons. Shapes are considered to consist of several simpler, intersecting shapes. Our method is based on the junction rule: the ...
    • Patch-type Segmentation of Voxel Shapes using Simplified Surface Skeletons 

      Reniers, Dennie; Telea, Alexandru (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a new method for decomposing a 3D voxel shape into disjoint segments using the shape s simplified surface-skeleton. The surface skeleton of a shape consists of 2D manifolds inside its volume. Each skeleton point ...
    • Perceptual Evaluation of Color-to-Grayscale Image Conversions 

      Cadik, M. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Color images often have to be converted to grayscale for reproduction, artistic purposes, or for subsequent processing. Methods performing the conversion of color images to grayscale aim to retain as much information about ...
    • Photon-driven Irradiance Cache 

      Brouillat, J.; Gautron, P.; Bouatouch, K. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We describe a global illumination method combining two well known techniques: photon mapping and irradiance caching. The photon mapping method has the advantage of being view independent but requires a costly additional ...
    • Preface, Table of Contents, Cover 

      Unknown author (The Eurographics Association and Blackwell Publishing, Inc, 2008)
    • A Prism-Free Method for Silhouette Rendering in Inverse Displacement Mapping 

      Chen, Ying-Chieh; Chang, Chun-Fa (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Silhouette is a key feature that distinguishes displacement mapping from normal mapping. However the silhouette rendering in the GPU implementation of displacement mapping (which is often called inversed displacement ...
    • Progressive Interpolation based on Catmull-Clark Subdivision Surfaces 

      Chen, Zhongxian; Luo, Xiaonan; Tan, Le; Ye, Binghong; Chen, Jiapeng (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We introduce a scheme for constructing a Catmull-Clark subdivision surface that interpolates the vertices of a quadrilateral mesh with arbitrary topology. The basic idea here is to progressively modify the vertices of an ...
