    • Linear Interval Estimations for Parametric Objects Theory and Application 

      Buehler, Katja (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      The new concept of parametrized bounding volumes for parametric objects is proposed to replace the common compact bounding volumes like axis aligned bounding boxes and parallelepipeds. Linear Interval Estimations (LIEs) ...

    • A low cost 3D scanner based on structured light 

      Rocchini, C.; Cignoni, P.; Montani, C.; Pingi, P.; Scopigno, R. (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Automatic 3D acquisition devices (often called 3D scanners) allow to build highly accurate models of real 3D objects in a cost- and time-effective manner. We have experimented this technology in a particular application ...

    • Mesh Optimization for Polygonized Isosurfaces 

      Ohtake, Yutaka; Belyaev, Alexander G. (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      In this paper, we propose a method for improvement of isosurface polygonizations. Given an initial polygonization of an isosurface, we introduce a mesh evolution process initialized by the polygonization. The evolving mesh ...

    • Modeling Dynamic Hair as a Continuum 

      Hadap, Sunil; Magnenat-Thalmann, Nadia (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      In this paper we address the difficult problem of hair dynamics, particularly hair-hair and hair-air interactions. To model these interactions, we propose to consider hair volume as a continuum. Subsequently, we treat the ...

    • Modeling Stochastic Dynamical Systems for Interactive Simulation 

      Reissell, L.-M.; Pai, Dinesh K. (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      We present techniques for constructing approximate stochastic models of complicated dynamical systems for applications in interactive computer graphics. The models are designed to produce realistic interaction at low cost.We ...

    • On-the-Fly Processing of Generalized Lumigraphs 

      Schirmacher, Hartmut; Ming, Li; Seidel, Hans-Peter (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      We introduce a flexible and powerful concept for reconstructing arbitrary views from multiple source images on the fly. Our approach is based on a Lumigraph structure with per-pixel depth values, and generalizes the classical ...

    • PC-based Real-time Texture Painting on Real World Objects 

      Iwakiri, Yuya; Kaneko, Toyohisa (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      The problem of texture mapping on real world objects has attracted attention11,8 recently. A work by Lensch et al.9 addressed the problem of locating a camera position in the celestial sphere and then mapping the acquired ...

    • Perceptually Guided Corrective Splatting 

      Haber, Jorg; Myszkowski, Karol; Yamauchi, Hitoshi; Seidel, Hans-Peter (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      One of the basic difficulties with interactive walkthroughs is the high quality rendering of object surfaces with non-diffuse light scattering characteristics. Since full ray tracing at interactive rates is usually impossible, ...

    • Rapid High Quality Compression of Volume Data for Visualization 

      Nguyen, Ky Giang; Saupe, Dietmar (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Volume data sets resulting from, e.g., computerized tomography (CT) or magnetic resonance (MR) imaging modalities require enormous storage capacity even at moderate resolution levels. Such large files may require compression ...

    • Ray Tracing Triangular Bezier Patches 

      Roth, S. H. Martin; Diezi, Patrick; Gross, Markus H. (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      We present a new approach to finding ray-patch intersections with triangular Bernstein-Bezier patches of arbitrary degree. This paper extends and complements on the short presentation17 . Unlike a previous approach which ...

    • Real-Time Cloud Rendering 

      Harris, Mark J.; Lastra, Anselmo (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      This paper presents a method for realistic real-time rendering of clouds suitable for flight simulation and games. It provides a cloud shading algorithm that approximates multiple forward scattering in a preprocess, and ...

    • Real-Time Volume Deformations 

      Westermann, Rudiger; Rezk-Salama, Christof (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Real-time free-form deformation tools are primarily based on surface or particle representations to allow for interactive modification and fast rendering of complex models. The efficient handling of volumetric representations, ...

    • Reflective Interaction in Virtual Environments 

      Lane, JRT; Lalioti, V. (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      The proliferation of projection-based systems in recent years resulted in a variety of specialised interaction techniques that make Virtual Environments a better man machine interface. However, the success of these techniques ...

    • Rendering Pearlescent Appearance Based On Paint-Composition Modelling 

      Ershov, Sergey; Kolchin, Konstantin; Myszkowski, Karol (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      We describe a new approach to modelling pearlescent paints based on decomposing paint layers into stacks of imaginary thin sublayers. The sublayers are chosen so thin that multiple scattering can be considered across ...

    • Rendering: Input and Output 

      Rushmeier, H. (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Rendering is the process of creating an image from numerical input data. In the past few years our ideas about methods for acquiring the input data and the form of the output have expanded. The availability of inexpensive ...

    • Resampling Feature and Blend Regions in Polygonal Meshes for Surface Anti-Aliasing 

      Botsch, Mario; Kobbelt, Leif (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Efficient surface reconstruction and reverse engineering techniques are usually based on a polygonal mesh representation of the geometry: the resulting models emerge from piecewise linear interpolation of a set of sample ...

    • Spatial Patches - A Primitive for 3D Model Representation 

      Ivanov, D.; Kuzmin, Ye. (Blackwell Publishers Ltd and the Eurographics Association, 2001)
