    • Measuring and Rendering Art Paintings Using an RGB Camera 

      Tominaga, Shoji; Tanaka, Norihiro (Eurographics Association, 2002)
      A method is proposed for measuring and rendering of art paints by using the simple system of an RGB camera only. The surface shape of an art painting is considered as a rough plane rather than a three-dimensional curved ...
    • Reverse Diffusion for Smooth Buildup of Progressivly Transmitted Geometry 

      Buelow, Thomas (Eurographics Association, 2002)
      In this paper we consider 3D object surfaces which can be represented as scalar functions defined on the sphere. These objects can be modeled as series of spherical harmonic functions. A simple progressive transmission ...
    • Geometric Data Structures for Computer Graphics 

      Zachmann, Gabriel; Langetepe, Elmar (Eurographics Association, 2002)
      This tutorial aims at presenting a wide range of geometric data structures, algorithms and techniques from computational geometry to computer graphics practitioners. To achieve this goal we introduce several data structures, ...
    • Frame-Coherent Stippling 

      Meruvia Pastor, Oscar E.; Strothotte, Thomas (Eurographics Association, 2002)
      Stippling is an artistic rendering technique where shading and texture is given by placing points or stipples on the canvas until the desired darkness is achieved. Computer-generated stippling has focused on producing high ...
    • Adaptive Compression of Human Animation Data 

      Ahmed, Amr Adel Hassan; Hilton, Adrian; Mokhtarian, Farzin (Eurographics Association, 2002)
      In this paper we introduce an adaptive motion compression technique using the discrete wavelet transform. Based on the analysis of human animation data, and its frequency contents, the wavelet analysis is utilised to achieve ...
    • Function-defined shape node for VRML 

      Lai, Feng Min; Sourin, Alexei (Eurographics Association, 2002)
      This paper describes how the web-based visualisation can be greatly improved using the function-based shape modelling technique. We propose the function-defined VRML shape node, which allows the content creators to describe ...
    • From Textual Chats to Interest Groups in 3D Virtual Space 

      Masa, Michal; Zara, Jiri (Eurographics Association, 2002)
      While the textual chat is a highly popular tool for various kinds of social interactions, its extension to the visual three-dimensional domain remains almost untouched and without practical utilization yet. This paper ...
    • View Interpolation for Dynamic Scenes 

      Xiao, Jiangjian; Rao, Cen; Shah, Mubarak (Eurographics Association, 2002)
      This paper describes a novel technique for synthesizing a dynamic scene from two images without the use of a 3D model. A scene containing rigid or non-rigid objects, in which each object can move in any orientation or ...
    • Tree balancing for mesh simplification 

      Grabner, Markus (Eurographics Association, 2002)
      In this paper, a tree balancing technique is presented that reduces the number of hierarchy levels in typical paircontraction based mesh simplification methods. A well-balanced hierarchy is essential for data structures ...
    • Normal Enhancement for Interactive Non-photorealistic Rendering 

      Cignoni, Paolo; Scopigno, Roberto; Tarini, Marco (Eurographics Association, 2002)
      We present a simple technique to improve the perception of shape of an object. Bump mapping is well-known in the computer graphics community for providing the impression of small-scale geometrical features (which actually ...
    • Adaptive Tessellation for Trimmed NURBS Surface 

      YingLiang, Ma; Hewitt, Terry (Eurographics Association, 2002)
      We present an adaptive method for tessellating the trimmed NURBS surface in the parametric domain. Given a model space tolerance ε, the algorithm first splits the NURBS surface in both the U and V directions to fit within ...
