    • The InViWo virtual agents 

      Richard, N.; Codognet, P.; Grumbach, A. (Eurographics Association, 1999)
      The InViWo project aims at providing non-computer scientists with high-level tools to create inhabited virtual worlds, i.e. in which autonomous agents and avatars can interact. In this paper, we describe the agent model ...

    • Visible Surface Reconstruction with Accurate Localization of Object Boundaries 

      March, Riccardo; Pedersini, Federico (Eurographics Association, 1999)
      An important problem in 3D reconstruction from multiple perspective views is the accurate recovery of surfaces near the discontinuities (object boundaries and creases). A common limitation of many techniques based on ...

    • Scanning Michelangelos Florentine Pieta: Making the Results Usable 

      Bernardini, F.; Mittleman, J.; Rushmeier, H.; Taubin, G. (Eurographics Association, 1999)
      We describe a project to create a three dimensional digital model ofMichelangelo’s Florentine Pietà. In particular, we examine how to edit and interactively view the model that consists of millions of triangles and hundreds ...

    • HIT! BAT! IT! 

      Maegawa, Hideaki (Eurographics Association, 1999)
      Today’s high technology is tomorrow’s standard technology. In this rapidly progressing computer graphics world, my goal as designer is to polish and improve on the "old" and well-used skills. This production was originally ...

    • Virtual Reconstruction of Medieval Architecture 

      Masuch, M.; Freudenberg, B.; Ludowici, B.; Kreiker, S.; Strothotte, T. (Eurographics Association, 1999)
      We describe the reconstruction of a medieval building as an example of how the use of 3D computer graphics can facilitate the reconstruction of an ancient site. We suggest that different stages of a virtual reconstruction ...

    • A Pyramidal Hemisphere Subdivision Method for Monte Carlo Radiosity 

      Jolivet, Vincent; Plemenos, Dimitri; Sbert, Mateu (Eurographics Association, 1999)
      In this paper we present a new method to improve Monte Carlo radiosity by sending more rays towards selected directions. More precisely, we determine regions of the scene where the distribution of the power must be done ...

    • WebTalk: a 3D collaborative environment to access the Web 

      Paolini, P.; Barbieri, T.; Loiudice, P.; Alonzo, F.; Arru, M.; Zanti, M.; Gaia, G. (Eurographics Association, 1999)
      The notion of cooperative visit and interaction within a web site, both at 2D and 3D level, could add decisive motivation to pursue exploitation of the third dimension in networked environments. A prototype developed at ...

    • A Rapid Clustering Algorithm for Efficient Rendering 

      Müller, Gordon; Schäfer, Stephan; Fellner, Dieter W. (Eurographics Association, 1999)
      Hierarchical radiosity using object clusters greatly improves rendering times and reduces memory consumption of radiosity computations. The key feature of the algorithm is using a hierarchy of object clusters to approximate ...

    • Fast Distance Field Interpolation for Reconstruction of Surfaces from Contours 

      Klein, Reinhard; Schilling, Andreas (Eurographics Association, 1999)
      One simple and robust way to get a reconstruction of surfaces from a given contour stack dealing well with branching and other problems which are generally difficult to solve is based on the well known MC-algorithm. To ...

    • Accelerated Artificial Landscape Visualisation 

      James, A.; Day, A.M. (Eurographics Association, 1999)
      We describe the design and implementation of four stages in an artificial landscape visualisation program. We begin by outlining a very simple but quick method of generating structurally realistic landscapes. We describe ...

    • Creating light-weight virtual humans for Virtual Environments 

      Oliveira, Joao; Buxton, Bernard (Eurographics Association, 1999)
      With the advent of whole body, 3D electro-optical scanners, a new range of applications are emerging that exploit the availability of personalised, realistic human models. However, realistic rendering of such models usually ...

    • A Minimalist Approach to Facial Reconstruction 

      Gotla, M.; Huang, Z. (Eurographics Association, 1999)
      We propose a minimalist approach to 3D facial reconstruction. By applying cognitive and anatomical heuristics, we show that a realistic face model can be reconstructed from a generic face model using only one or two real ...

    • Psycho-social Happenings in Mediated Environments 

      Knipp, Tammy (Eurographics Association, 1999)
      One of the virtues of our changing times is that new media has challenged us to rethink and re-examine our basic presumptions about reality and the reality that is virtually perceived. From the perspective of an elec - ...

    • Wavelet Projections for Volume Rendering 

      Horbelt, Stefan; Unser, Michael; Vetterli, Martin (Eurographics Association, 1999)
      We extended Gross’s 3 method of volume wavelet rendering by computing splats via an orthogonal projection operator. The method decomposes the volume data into a wavelet pyramid representation in the spline domain. The ...

    • Adaptive Scattered Data Interpolation with Multilevel Nonuniform B-Splines 

      Lin, J.; Huang, Z. (Eurographics Association, 1999)
      We present an adaptive method for scattered data interpolation. The method is based on multilevel nonuniform Bsplines. It makes use of a coarse-to-fine hierarchy of control lattices to generate a sequence of bicubic ...

    • Schock in the ear: sound and new media art 

      Neumark, Norie (Eurographics Association, 1999)
      New media art generally fails to engage with the imaginative and artistic possibilities and particularities of sound. Shock in the Ear is a sound -centred experimental art CDROM which explores shock -- from culture shock ...

    • The Danteum 

      Nagakura, Takehiko (Eurographics Association, 1999)
      The Danteum was a building designed for Rome in 1938 by two eminent Italian architects, Giuseppe Terragni and Pietro Lingeri. Due to the defeat of their client, Mussolini, in WW II, the project was never realized and became ...

    • A Global Routing Mechanism for Modular VRML-Worlds 

      Mader, S. (Eurographics Association, 1999)
      With the increasing complexity of virtual worlds VRML97 reveals its lack of native support for logical modularization of these worlds. Though the inherent mechanisms as PROTO-typing and Inlining allow us to partition our ...

    • Better Pasting Via Quasi-Interpolation 

      Mann, Stephen; Conrad, Blair (Eurographics Association, 1999)
      In this poster, we show our latest work on surface pasting, a hierarchical modeling technique. In surface pasting, we attach a feature surface to a base surface using an approximation technique. While we can use knot ...

    • Computer Animation of Pianist’s Hand 

      Kim, Junhwan (Eurographics Association, 1999)
      In this paper we present an algorithm for the animation of the pianist’s hand and the determination of piano fingering based on the animation. The animation shows feasible movement of hands and fingers. In general, the ...
