    • Multiresolution for Algebraic Curves and Surfaces using Wavelets 

      Esteve, Jordi; Brunet, Pere; Vinacua, Alvar (Blackwell Publishers Ltd and the Eurographics Association., 2001)
      This paper describes a multiresolution method for implicit curves and surfaces. The method is based on wavelets, and is able to simplify the topology. The implicit curves and surfaces are defined as the zero-valued piece-wise ...
    • A Recursive Subdivision Algorithm for Piecewise Circular Spline 

      Nasri, Ahmad H.; Van Overveld, C. W. A. M.; Wyvill, Brian (Blackwell Publishers Ltd and the Eurographics Association., 2001)
      We present an algorithm for generating a piecewise G1 circular spline curve from an arbitrary given control polygon. For every corner, a circular biarc is generated with each piece being parameterized by its arc length. ...
    • 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 ...
    • Recent Advances in Volume Visualization 

      Brodlie, Ken; Wood, Jason (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      In the past few years, there have been key advances in the three main approaches to the visualization of volumetric data: isosurfacing, slicing and volume rendering, which together make up the field of volume visualization.In ...
    • Adaptive Implicit Surface Polygonization Using Marching Triangles 

      Akkouche, Samir; Galin, Eric (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      This paper presents several improvements to the marching triangles algorithm for general implicit surfaces. The original method generates equilateral triangles of constant size almost everywhere on the surface. We present ...
    • A Novel Approach for Delaunay 3D Reconstruction with a Comparative Analysis in the Light of Applications 

      Nonato, L.; Minghim, R.; Oliveira, M. C. F.; Tavares, G. (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      This paper presents a novel algorithm for volumetric reconstruction of objects from planar sections using Delaunay triangulation, which solves the main problems posed to models defined by reconstruction, particularly from ...
    • Adaptive Representation of Specular Light 

      Briere, Normand; Poulin, Pierre (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Caustics produce beautiful and intriguing illumination patterns. However, their complex behavior makes them difficult to simulate accurately in all but the simplest configurations. To capture their appearance, we present ...
    • Fast and Controllable Simulation of the Shattering of Brittle Objects 

      Smith, Jeffrey; Witkin, Andrew; Baraff, David (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      We present a method for the rapid and controllable simulation of the shattering of brittle objects under impact. An object is represented as a set of point masses connected by distance-preserving linear constraints. This ...
    • Constrained Fairing for Meshes 

      Liu, Xinguo; Bao, Hujun; Heng, PhengAnn; Wong, TienTsin; Peng, Qunsheng (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      In this paper, we present a novel fairing algorithm for the removal of noise from uniform triangular meshes without shrinkage and serious distortion. The key feature of this algorithm is to keep all triangle centers invariant ...
    • The John Lansdown Award 

      Jones, Huw; Willis, Phil (Blackwell Publishers Ltd and the Eurographics Association., 2001)
    • Erratum: Conflict Neutralization on Binary Space Partitioning 

      James, A.; Day, A. M. (Blackwell Publishers Ltd and the Eurographics Association., 2001)
    • 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 ...
    • 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 ...
    • 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 ...
    • Flexible Image-Based Photometric Reconstruction using Virtual Light Sources 

      Gibson, Simon; Howard, Toby; Hubbold, Roger (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Photometric reconstruction is the process of estimating the illumination and surface reflectance properties of an environment, given a geometric model of the scene and a set of photographs of its surfaces. For mixed-reality ...
