    • 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 ...
    • 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 ...
    • Texture Mapping on Doo-Sabin Subdivision Surfaces Using Multiple Images 

      Huang, Zhiyong; Neo, Chee Seng (Eurographics Association, 2002)
      We propose a texture mapping method on subdivision surfaces using multiple images and have implemented it on Doo- Sabin scheme. At the beginning, one texture map is specified for each control mesh face respectively. In a ...
    • Real-time 3D Deformations by Means of Compactly Supported Radial Basis Functions 

      Kojekine, Nikita; Savchenko, Vladimir; Senin, Mikhail; Hagiwara, Ichiro (Eurographics Association, 2002)
      We present an approach to real-time animation of deformable objects. Optimization of algorithms using compactly supported radial basis functions (CSRBF) allows us to generate deformations performed fast enough for such ...
    • SAVANT: A new efficient approach to generating the visual hull 

      Lyons, Alex; Kotcheff, Aaron (Eurographics Association, 2002)
      We present a new approach to generating a boundary representation (a polygonal mesh) of the visual hull from a set of silhouettes of an object taken from known camera positions. The approach uses spatial subdivision to ...
    • Texture Minification using Quad-trees and Fipmaps 

      Bornik, Alexander; Ferko, Andrej (Eurographics Association, 2002)
      The paper extends the recently published methods for image reconstruction and texture minification using the generalized ripmap method, named fipmap, and quad-trees. Fipmap is based on the technique of partitioned iterated ...
    • Texturing Calibrated Head Model from Images 

      Lempitsky, Victor; Ivanov, Denis; Kuzmin, Yevgeniy (Eurographics Association, 2002)
      In this paper we address a well-known problem of producing an animated model of a human head from a pair of orthogonal photographs and present a new technique of generating consistent high-quality texture for a polygonal ...
    • Flexible bump map capture from video 

      Paterson, James Alexander; Fitzgibbon, Andrew W. (Eurographics Association, 2002)
      We extend recent techniques for the automated capture of surface normal maps or bump maps from real-world material samples. In contrast to recent systems, which have required cumbersome laboratory setups with careful ...
    • Rendering Artistic Line Drawings Using Off-the-Shelf 3-D Software 

      Loviscach, Jörn (Eurographics Association, 2002)
      Most commercial 3-D software packages used for animated films and still picture production offer merely rudimentary support for non-photorealistic rendering. However, nearly all of these packages possess interfaces which ...
    • Automated Enhancement of 3D Models 

      Torres-Mendez, L.A.; Dudek, G. (Eurographics Association, 2002)
      The acquisition of a 3D model of a real environment can be accomplished using range sensors. In practice, suitable sensors to densely cover a large environment are often impractical. This paper presents ongoing work on the ...
