  • Wicke, Martin; Olibet, Sandro; Gross, Markus (The Eurographics Association, 2005)
    We present an algorithm to convert point-sampled objects to textured meshes. The output mesh carries the geometric information present in the input model, while information about color and other surface attributes is ...
  • Keiser, Richard; Adams, Bart; Gasser, Dominique; Bazzi, Paolo; Dutré, Philip; Gross, Markus (The Eurographics Association, 2005)
    We present a framework for physics-based animation of deforming solids and fluids. By merging the equations of solid mechanics with the Navier-Stokes equations using a particle-based Lagrangian approach, we are able to ...
  • Rovira, Jordi; Wonka, Peter; Castro, Francesc; Sbert, Mateu (The Eurographics Association, 2005)
    In this paper we address the problem of extracting representative point samples from polygonal models. The goal of such a sampling algorithm is to find points that are evenly distributed. We propose star-discrepancy as a ...
  • Krüger, Jens; Schneider, Jens; Westermann, Rüdiger (The Eurographics Association, 2005)
    In this paper we present a compression scheme for large point scans including per-point normals. For the encoding of such scans we introduce a particular type of closest sphere packing grids, the hexagonal close packing ...
  • Schall, Oliver; Belyaev, Alexander; Seidel, Hans-Peter (The Eurographics Association, 2005)
    In this paper, we develop a method for robust filtering of a noisy set of points sampled from a smooth surface. The main idea of the method consists of using a kernel density estimation technique for point clustering. ...
  • Miao, Lanfang; Huang, Jin; Liu, Xinguo; Bao, Hujun; Peng, Qunsheng; Guo, Baining (The Eurographics Association, 2005)
    Point sets have become a popular shape representation. In this paper, we present a novel approach to computing variation modes for point set surfaces, and represent the point set surface as a linear combination of the ...
  • Reuter, Patrick; Joyot, Pierre; Trunzler, Jean; Boubekeur, Tamy; Schlick, Christophe (The Eurographics Association, 2005)
    There are many techniques that reconstruct continuous 3D surfaces from scattered point data coming from laser range scanners. One of the most commonly used representations are Point Set Surfaces (PSS) defined as the set ...
  • Sadlo, Filip; Weyrich, Tim; Peikert, Ronald; Gross, Markus (The Eurographics Association, 2005)
    We present a simple and high-quality 3D scanning system based on structured light. It uses the common setup of a video projector, a computer-controlled turntable and a single camera. Geometry is acquired using a combination ...
  • Dey, Tamal K.; Li, Gang; Sun, Jian (The Eurographics Association, 2005)
    Many applications that process a point cloud data benefit from a reliable normal estimation step. Given a point cloud presumably sampled from an unknown surface, the problem is to estimate the normals of the surface at the ...
  • Cazals, Frederic; Giesen, Joachim; Pauly, Mark; Zomorodian, Afra (The Eurographics Association, 2005)
    We define a new filtration of the Delaunay triangulation of a finite set of points in Rd, similar to the alpha shape filtration. The new filtration is parameterized by a local scale parameter instead of the global scale ...
  • Bremer, Peer-Timo; Hart, John C. (The Eurographics Association, 2005)
    Recently, point set surfaces have been the focus of a large number of research efforts. Several different methods have been proposed to define surfaces from points and have been used in a variety of applications. However, ...
  • Wu, Jianhua; Zhang, Zhuo; Kobbelt, Leif (The Eurographics Association, 2005)
    Surface splatting enables high quality and efficient rendering algorithms for dense point-sampled datasets. However, with increasing data complexity, the need for multiresolution models becomes evident. For triangle meshes, ...
  • Talton, Jerry O.; Carr, Nathan A.; Hart, John C. (The Eurographics Association, 2005)
    Point-based representations are becoming increasingly common in computer graphics, especially for visualizing data sets where the number of points is large relative to the number of pixels involved in their display. When ...
  • Botsch, Mario; Hornung, Alexander; Zwicker, Matthias; Kobbelt, Leif (The Eurographics Association, 2005)
    Because of their conceptual simplicity and superior flexibility, point-based geometries evolved into a valuable alternative to surface representations based on polygonal meshes. Elliptical surface splats were shown to allow ...
  • Wald, Ingo; Seidel, Hans-Peter (The Eurographics Association, 2005)
    Point-based methods have recently gained significant interest, as their simplicity and independence of connectivity make them a simple and powerful tool in both modelling and rendering. Still, their use for high-quality ...
