    • Adaptive Acquisition of Lumigraphs from Synthetic Scenes 

      Schirmacher, Hartmut; Heidrich, Wolfgang; Seidel, Hans-Peter (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      Light fields and Lumigraphs are capable of rendering scenes of arbitrary geometrical or illumination complexity in real time. They are thus interesting ways of interacting with both recorded real-world and high-quality ...

    • Perceptual Principles and Computer Graphics 

      May, Jon (Blackwell Publishers Ltd and the Eurographics Association, 1999)

    • An Adaptive Method for Area Light Sources and Daylight in Ray Tracing 

      Zaninetti, Jacques; Boy, Pierre; Peroche, Bernard (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      This paper proposes an adaptive method for taking both (diffuse or not) planar area light sources and daylight into account in a ray tracing environment which separates the calculation of direct and indirect illumination. ...

    • Improved Laplacian Smoothing of Noisy Surface Meshes 

      Vollmer, J.; Mencl, R.; Muller, H. (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      This paper presents a technique for smoothing polygonal surface meshes that avoids the well-known problem of deformation and shrinkage caused by many smoothing methods, like e.g. the Laplacian algorithm. The basic idea is ...

    • A Shrink Wrapping Approach to Remeshing Polygonal Surfaces 

      Kobbelt, Leif P.; Vorsatz, Jens; Labsik, Ulf and (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      Due to their simplicity and flexibility, polygonal meshes are about to become the standard representation for surface geometry in computer graphics applications. Some algorithms in the context of multiresolution representation ...

    • A Free Form Feature Taxonomy 

      Fontana, M.; Giannini, F.; Meirana, M. (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      In this paper the notion of free form feature for aesthetic design is presented. The design of industrial products constituted by free form surfaces is done by using CAD systems representing curves and surfaces by means ...

    • A Practical Analysis of Clustering Strategies for Hierarchical Radiosity (Supplementary material) 

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

    • 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 ...

    • 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 ...

    • 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)

    • Modeling and Rendering Escher-Like Impossible Scenes 

      Savransky, Guillermo; Dimerman, Dan; Gotsman, Craig (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      Inspired by the drawings of "impossible" objects by artists such as M.C. Escher, we describe a mathematical theory which captures some of the underlying principles of their work. Using this theory, we show how impossible ...

    • Erratum 

      Unknown author (Blackwell Publishers Ltd and the Eurographics Association, 1999)

    • Modelling and Rendering Graphics Scenes Composed of Multiple Volumetric Datasets 

      Leu, Adrian; Chen, Min (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      This paper presents a method for modelling graphics scenes consisting of multiple volumetric objects. A two-level hierarchical representation is employed, which enables the reduction of the overall storage consumption as ...

    • Generic Geometric Programming in the Computational Geometry Algorithms Library 

      Veltkamp, Remco C. (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      This paper describes a number of design issues and programming paradigms that affect the development of Cgal, the computational geometry algorithms library. Genericity of the library is achieved by concepts such as templates, ...

    • Fast Ray Tracing of Implicit Surfaces 

      Sherstyuk, Andrei (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      A ray-tracing algorithm is described for rendering implicit surfaces formed with C1-continuous bounded functions f(x, y, z). This class of functions includes such popular implicit models as blobby molecules, metaballs, ...

    • Extending the CSG Tree. Warping, Blending and Boolean Operations in an Implicit Surface Modeling System 

      Wyvill, Brian; Guy, Andrew; Galin, Eric (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      Automatic blending has characterized the major advantage of implicit surface modeling systems. Recently, the introduction of deformations based on space warping and Boolean operations between primitives has increased the ...

    • Multiresolution Curve and Surface Representation: Reversing Subdivision Rules by Least-Squares Data Fitting 

      Samavati, Faramarz F.; Bartels, Richard H. (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      This work explores how three techniques for defining and representing curves and surfaces can be related efficiently. The techniques are subdivision, least-squares data fitting, and wavelets. We show how least-squares data ...
