    • 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 ...

    • 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 ...

    • 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 ...

    • 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)
      The calculation of radiant energy balance in complex scenes has been made possible by hierarchical radiosity methods based on clustering mechanisms. Although clustering offers an elegant theoretical solution by reducing ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...
