    • An Adaptive Spectral Rendering with a Perceptual Control 

      Claude Iehl, Jean; Peroche, Bernard (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      In this paper, we present a spectral rendering method based on a ray tracing algorithm and guided by a perceptual control of the error made. An adaptive representation of spectral data for light sources and materials is ...

    • An Advanced Color Representation for Lossy Compression of CMYK Prepress Images 

      De Neve, P.; Denecker, K.; Philips, W.; Lemahieu, I. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      CMYK color images are used extensively in prepress applications. When compressing those color images one has to deal with four different color channels. Usually compression algorithms only take into account the spatial ...

    • Augmented Reality with Back-Projection Systems using Transflective Surfaces 

      Bimber, Oliver; Encarnacao, L. Miguel; Schmalstieg, Dieter (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      In this paper, we introduce the concept of Extended VR (extending viewing space and interaction space of back-projection VR systems), by describing the use of a hand-held semi-transparent mirror to support augmented reality ...

    • Automatic Camera Placement for Image-Based Modeling 

      Fleishman, Shachar; Cohen-Or, Daniel; Lischinski, Dani (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      We present an automatic camera placement method for generating image-based models from scenes with known geometry. Our method first approximately determines the set of surfaces visible from a given viewing area and then ...

    • Automatic Creation of Object Hierarchies for Radiosity Clustering 

      Muller, Gordon; Schafer, Stephan; Fellner, Dieter W. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      Using object clusters for hierarchical radiosity greatly improves the efficiency and thus usability of radiosity computations. By eliminating the quadratic starting phase very large scenes containing about 100k polygons ...

    • Automatic Generation of Virtual Woodblocks and Multicolor Woodblock Printing 

      Mizuno, S.; Kasaura, T.; Okouchi, T.; Yamamoto, S.; Okada, M.; Toriwaki, J. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      In this paper, we study a method to synthesize a multicolor virtual woodblock print by using several virtual woodblocks. It consists of two sections: carving and printing, to synthesize a virtual print. In the carving ...

    • Automatic Surface Reconstruction from Point Sets in Space 

      Attene, Marco; Spagnuolo, Michela (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      In this paper an algorithm is proposed that takes as input a generic set of unorganized points, sampled on a real object, and returns a closed interpolating surface. Specifically, this method generates a closed 2-manifold ...

    • Binding Virtual Environments to Toolkit Capabilities 

      Smith, Shamus P.; Duke, David J. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      There are many toolkits and development environments that aid the process of constructing virtual environment applications. Many of these development environments encourage customising a virtual environment's design while ...

    • Carla Vandoni - A Remarkable Lady 

      Duce, David (Blackwell Publishers Ltd and the Eurographics Association, 2000)

    • Collaborative Virtual Simulation Environment for Radiotherapy Treatment Planning 

      Cai, Wenli; Walter, Stefan; Karangelis, Grigorios; Sakas, Georgios (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      The simulation of Radiotherapy Treatment Planning (RTP) is a normal procedure in oncology clinics carried out on a Simulator machine. The Virtual Simulation of RTP replaces the real Simulator machine with a virtual one by ...

    • Color Distribution - A New Approach to Texture Compression 

      Ivanov, Denis V.; Kuzmin, Yevgeniy P. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      Texture compression is recently one of the most important topics of 3D scene rendering techniques, because it allows rendering more complicated high-resolution scenes. However, because of some special requirements for these ...

    • Computation of Irradiance from Triangles by Adaptive Sampling 

      Urena, C. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      We introduce an algorithm for sample positioning in a planar triangle, which can be used to make numerical integration of an arbitrary function defined on it. This algorithm has some interesting properties which make it ...

    • Conflict Neutralization on Binary Space Partitioning 

      James, A.; Day, A.M. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      The Binary Space Partitioning (BSP) tree achieves fast hidden surface removal for most practical applications where an observer can move through a scene of static objects. However, the BSP algorithm generally increases the ...

    • Constructive Volume Geometry 

      Chen, Min; Tucker, John V. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      We present an algebraic framework, called Constructive Volume Geometryn (CVG), for modelling complex spatial objects using combinational operations. By utilising scalar fields as fundamental building blocks, CVG provides ...

    • Context-based Space Filling Curves 

      Dafner, Revital; Cohen-Or, Daniel; Matias, Yossi (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      A context-based scanning technique for images is presented. An image is scanned along a context-based space filling curve that is computed so as to exploit inherent coherence in the image. The resulting one-dimensional ...
