    • 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)
      The commonly used solution for real-life 3D model representation is polygonal spatially consistent geometry, with texture, and, optionally, bump or displacement maps attached. Although the idea of displacement mapping is ...

    • Streaming of Complex 3D Scenes for Remote Walkthroughs 

      Teler, Eyal; Lischinski, Dani (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      We describe a new 3D scene streaming approach for remote walkthroughs. In a remote walkthrough, a user on a client machine interactively navigates through a scene that resides on a remote server. Our approach allows a user ...

    • The Synthesis of Rock Textures in Chinese Landscape Painting 

      Way, Der-Lor; Shih, Zen-Chung (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      In Chinese landscape painting, rock textures portray the orientation of mountains and contribute to the atmosphere. Many landscape-painting skills are required according to the type of rock. Landscape painting is the major ...

    • Tensor Topology Tracking: A Visualization Method for Time-Dependent 2D Symmetric Tensor Fields 

      Tricoche, X.; Scheuermann, G.; Hagen, H. (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Topological methods produce simple and meaningful depictions of symmetric, second order two-dimensional tensor fields. Extending previous work dealing with vector fields, we propose here a scheme for the visualization of ...

    • Texture Mapping with Hard Constraints 

      Eckstein, Ilya; Surazhsky, Vitaly; Gotsman, Craig (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      We show how to continuously map a texture onto a 3D triangle mesh when some of the mesh vertices are constrained to have given (u, v) coordinates. This problem arises frequently in interactive texture mapping applications ...

    • Tour Into the Picture using a Vanishing Line and its Extension to Panoramic Images 

      Kang, Hyung Woo; Pyo, Soon Hyoung; Anjyo, Ken-ichi; Shin, Sung Yong (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Tour into the picture (TIP) proposed by Horry et al.13 is a method for generating a sequence of walk-through images from a single reference picture (or image). By navigating a 3D scene model constructed from the picture, ...

    • A Unified Subdivision Scheme for Polygonal Modeling 

      Maillot, Jerome; Stam, Jos (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Subdivision rules have traditionally been designed to generate smooth surfaces from polygonal meshes. In this paper we propose to employ subdivision rules as a polygonal modeling tool, specifically to add additional level ...

    • Valence-Driven Connectivity Encoding for 3D Meshes 

      Alliez, Pierre; Desbrun, Mathieu (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      In this paper, we propose a valence-driven, single-resolution encoding technique for lossless compression of triangle mesh connectivity. Building upon a valence-based approach pioneered by Touma and Gotsman22 , we design ...

    • Visualization of Isosurfaces with Parametric Cubes 

      Mora, B.; Jessel, J.P.; Caubet, R. (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      To render images from volume datasets, an interpolation method also called reconstruction is needed. The level of details of the resultant image closely depends on the filter used for reconstruction. We propose here a new ...

    • Walk-Through Illustrations: Frame-Coherent Pen-and-Ink Style in a Game Engine 

      Freudenberg, Bert; Masuch, Maic; Strothotte, Thomas (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      In this paper we show how a game engine designed to generate photorealistic images can be extended to produce non-photorealistic and hybrid renditions. We introduce new hardware-based methods to accomplish pen-and-ink ...

    • Why Games Will Be the Preeminent Art Form of the 21stCentury 

      Hecker, Chris (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Computer games share many artistic and technical characteristics with films of the early 1900s. Games' artistic evolution is hampered by the lack of artistic respect from society at large, and the lack of technical standards ...
