    • 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, ...

    • Triangle Strip Compression 

      Isenburg, Martin (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      In this paper we introduce a simple and efficient scheme for encoding the connectivity and the stripification of a triangle mesh. Since generating a good set of triangle strips is a hard problem, it is desirable to do this ...

    • 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 ...

    • Visibility Driven Rasterization 

      Meissner, M.; Bartz, D.; Gunther, R.; Strasser, W. (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      We present a new visibility driven rasterization scheme that significantly increases the rendering performance of modern graphic subsystems. Instead of rasterizing, texturing, lighting, and depth-testing each individual ...

    • Visual Perception in Realistic Image Synthesis 

      McNamara, Ann (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Realism is often a primary goal in computer graphics imagery, and we strive to create images that are perceptually indistinguishable from an actual scene. Rendering systems can now closely approximate the physical distribution ...

    • 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 ...

    • Visualizing Stars and Emission Nebulas 

      Nadeau, David R.; Genetti, Jon D.; Napear, Steve; Pailthorpe, Bernard; Emmart, Carter; Wesselak, Erik and Davidson, Dennis (Blackwell Publishers Ltd and the Eurographics Association., 2001)
      We describe star and nebula visualization techniques used to create a 3D volumetric visualization of the Orion Nebula. The nebula's ionization layer is modeled first as a surface model, derived from infrared and visible ...

    • 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 ...
