    • 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 ...
    • 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 ...
    • Tone Reproduction and Physically Based Spectral Rendering 

      Devlin, Kate; Chalmers, Alan; Wilkie, Alexander; Purgathofer, Werner (Eurographics Association, 2002)
      The ultimate aim of realistic graphics is the creation of images that provoke the same responses that a viewer would have to a real scene. This STAR addresses two related key problem areas in this effort which are located ...
    • 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 ...
    • Tutorial on Inhabited Virtual Heritage 

      Magnenat-Thalmann, Nadia; Chalmers, Alan; Fua, Pascal; Thalmann, Daniel (Eurographics Association, 2002)
    • Using pre-integrated Transfer Functions in an Interactive Software System for Volume 

      Knittel, Guenter (Eurographics Association, 2002)
      We explore possibilities to implement classification based on pre-integrated transfer functions in a software system for high-speed volume rendering. The major obstacle to remove is the large size of the multi-dimensional ...
    • 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 ...
    • View-Dependent Rendering for Polygonal Datasets 

      El- Sana, Jihad; De Floriani, Leila; Puppo, Enrico; Shamir, Arik (Eurographics Association, 2002)
    • Visibility Preprocessing Using Spherical Sampling of Polygonal Patches 

      Meruvia Pastor, Oscar E. (Eurographics Association, 2002)
      A technique is presented that permits fast view-reconstruction of individual objects. This method improves a previous approach to solve the problem of approximated view reconstruction by combining clustering of polygons ...
    • Visual Data Mining 

      Keim, Daniel A.; Müller, Wolfgang; Schumann, Heidrun (Eurographics Association, 2002)
      Never before in history has data been generated at such high volumes as it is today. Exploring and analyzing the vast volumes of data has become increasingly difficult. Information visualization and visual data mining can ...
    • The Voronoi-Quadtree: construction and visualization 

      Coll, Narcís; Boada, Imma; Sellares, J.A. (Eurographics Association, 2002)
      We define a quadtree-based planar Voronoi diagram codification, the Voronoi-Quadtree, valid for generalized sites (points, line-segments, curve-arc segments, ...) and for different distance functions (Euclidean metrics, ...
