    • A New Method of Image Mosaicking and Its Application to Cultural Heritage Representation 

      Cortelazzo, G.M.; Lucchese, L. (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      This paper presents an original two-step procedure for estimating projective transformations between pairs of images: first, the transformation between the images is approximated as an affine transformation; second, this ...

    • Active Storytelling 

      Glassner, Andrew (Blackwell Publishers Ltd and the Eurographics Association, 1999)

    • Virtual Dunhuang Art Cave: A Cave within a CAVE 

      Lutz, B.; Weintke, M. (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      Virtual Reality can present historical places in a three-dimensional and interactive way, giving visitors a photorealistic impression of objects. Not only existing scenarios can be shown, but VR can also be used to rebuild ...

    • Stochastic Iteration for Non-diffuse Global Illumination 

      Szirmay-Kalos, Laszlo (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      This paper presents a single-pass, view-dependent method to solve the rendering equation, using a stochastic iterational scheme where the transport operator is selected randomly in each iteration. The requirements of ...

    • Multi-layered impostors for accelerated rendering 

      Decoret, Xavier; Sillion, Francois; Schaufler, Gernot; Dorsey, Julie (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      This paper describes the successful combination of pre-generated and dynamically updated image-based representations to accelerate the visualization of complex virtual environments. We introduce a new type of impostor, ...

    • The Digital Michelangelo Project 

      Levoy, Marc A. (Blackwell Publishers Ltd and the Eurographics Association, 1999)

    • An Efficient and Flexible Perception Pipeline for Autonomous Agents 

      Bordeux, Christophe; Boulic, Ronan; Thalmann, Daniel (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      Agents in virtual environments require a combination of perception and action to behave in an autonomous way. We extend a software architecture for the management of actions blending, called AGENTlib, with a perception ...

    • An Information Theory Framework for the Analysis of Scene Complexity 

      Feixas, Miquel; Del Acebo, Esteve; Bekaert, Philippe; Sbert, Mateu (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      In this paper we present a new framework for the analysis of scene visibility and radiosity complexity. We introduce a number of complexity measures from information theory quantifying how difficult it is to compute with ...

    • Computer-Generated Graphite Pencil Rendering of 3D Polygonal Models 

      Sousa, Mario Costa; Buchanan, John W. (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      Researchers in non-photorealistic rendering have investigated the display of three-dimensional worlds using various display models. In particular, recent work has focused on the modeling of traditional artistic media and ...

    • Compact Metallic Reflectance Models 

      Neumann, Laszlo; Neumannn, Attila; Szirmay-Kalos, Laszlo (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      The paper presents simple, physically plausible, but not physically based reflectance models for metals and other specular materials. So far there has been no metallic BRDF model that is easy to compute, suitable for fast ...

    • Weighted Multipass Methods for Global Illumination 

      Suykens, Frank; Willems, Yves D. (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      In multipass rendering, care has to be taken to include all light transport only once in the final solution. Therefore the different methods in current multipass configurations handle a perfectly disjunct part of the light ...

    • An Interactive Designing System with Virtual Sculpting and Virtual Woodcut Printing 

      Mizunoy, S.; Okadayy, M.; Toriwakiy, J. (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      In this paper, we propose an interactive designing method and a system based on it to create 3D objects and 2D images. This system consists of two subsystems for virtual sculpting to create a 3D shape and virtual printing ...

    • Capturing and Re-Using Rendition Styles for Non-Photorealistic Rendering 

      Hamel, J.; Strothotte, T. (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      Rendering high-quality non-photorealistic images of a given geometric model is often associated with a considerable amount of effort on the part of a user to fine-tune the rendition. In this paper we introduce a method and ...

    • Generalized View-Dependent Simplification 

      El-Sana, Jihad; Varshney, Amitabh (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      We propose a technique for performing view-dependent geometry and topology simplifications for level-of-detail-based renderings of large models. The algorithm proceeds by preprocessing the input dataset into a binary tree, ...

    • Interactive Multiresolution Editing of Arbitrary Meshes 

      Lee, Seungyong (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      This paper presents a novel approach to multiresolution editing of a triangular mesh. The basic idea is to embed an editing area of a mesh onto a 2D rectangle and interpolate the user-specified editing information over the ...

    • Texturing 3D Models of Real World Objects from Multiple Unregistered Photographic Views 

      Neugebauer, Peter J.; Klein, Konrad (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      As the efficiency of computer graphic rendering methods is increasing, generating realistic models is now becoming a limiting factor. In this paper we present a new technique to enhance already existing geometry models of ...

    • The Hybrid World of Virtual Environments 

      Smith, Shamus; Duke, David; Massink, Mieke (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      Much of the work concerned with virtual environments has addressed the development of new rendering technologies or interaction techniques. As the technology matures and becomes adopted in a wider range of applications, ...

    • A Practical Analysis of Clustering Strategies for Hierarchical Radiosity 

      Hasenfratz, Jean-Marc; Damez, Cyrille; Sillion, Francois; Drettakis, George (Blackwell Publishers Ltd and the Eurographics Association, 1999)
