    • 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 ...
    • Mesh Decimation for Displacement Mapping 

      Collins, Gordon; Hilton, Adrian (Eurographics Association, 2002)
      We present a mesh decimation algorithm for triangular meshes. Unlike other decimation algorithms we are not concerned with geometric error but with the existence of a displacement mapping which can map between the original ...
    • A Method for Creating Mosaic Images Using Voronoi Diagrams 

      Dobashi, Yoshinori; Haga, Toshiyuki; Johan, Henry; Nishita, Tomoyuki (Eurographics Association, 2002)
      This paper proposes a non-photorealistic rendering method that creates an artistic effect called mosaicing. The proposed method converts images provided by the user into the mosaic images. Commercial image editing applications ...
    • Modeling Visual Attention in VR: Measuring the Accuracy of Predicted Scanpaths 

      Duchowski, Andrew; Marmitt, Gerd (Eurographics Association, 2002)
      Dynamic human vision is an important contributing factor to the design of perceptually-based Virtual Reality. A common strategy relies on either an implicit assumption or explicit measurement of gaze direction. Given the ...
    • Multi-dimensional and Multi-scale Visualizer of Large XML Documents 

      Jacquemin, Christian; Jardino, Michele (Eurographics Association, 2002)
      3D-XV (3-Dimensional XML Visualizer) is an interactive graphical interface for accessing large structured documents. It relies on a geometrical model that combines a sequential organization and a hierarchical structure. ...
    • 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 ...
    • On the Integration of Synthetic Objects with Real-World Scenes 

      Abad, Francisco; Camahort, Emilio; Vivó, Roberto (Eurographics Association, 2002)
      This paper presents a method for integrating synthetic objects in real-world photographs. We take a set of photographs of a real scene and build a simple image-based model. We use high dynamic range images to build an ...
    • 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 ...
    • Real-Time Animated Grass 

      Bakay, Brook; Lalonde, Paul; Heidrich, Wolfgang (Eurographics Association, 2002)
      We present a simple method to render fields of grass, animated in the wind, in real-time. The technique employs vertex shaders to render displacement maps with Russian-doll style transparent shells. Animation is achieved ...
    • 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 ...
    • Rendering of Japanese Artcraft 

      Durikovic, Roman; Kolchin, Kostantin; Ershov, Sergey (Eurographics Association, 2002)
      We present several methods for simulation of Japanese lacquer ware, a prominent Far East Asian handicraft art. We consider two most popular kinds of Japanese lacquer ware made by the makie and nashiji techniques. For ...
    • 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 ...
    • 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 ...
    • Simulation of Cumuliform Clouds Based on Computational Fluid Dynamics 

      Miyazaki, Ryo; Dobashi, Yoshinori; Nishita, Tomoyuki (Eurographics Association, 2002)
      Simulation of natural phenomena is one of the important research fields in computer graphics. In particular, clouds play an important role in creating images of outdoor scenes. Fluid simulation is effective in creating ...
    • 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 ...
    • 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 ...
