  • A Unified Lagrangian Approach to Solid-Fluid Animation 

    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 ...

  • Conversion of Point-Sampled Models to Textured Meshes 

    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 ...

  • DUODECIM - A Structure for Point Scan Compression and Rendering 

    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 ...

  • Point Sampling with Uniformly Distributed Lines 

    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 ...

  • Computing Variation Modes for Point Set Surfaces 

    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 ...

  • Robust Filtering of Noisy Scattered Point Data 

    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. ...

  • A Practical Structured Light Acquisition System for Point-Based Geometry and Texture 

    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 ...

  • Surface Reconstruction with Enriched Reproducing Kernel Particle Approximation 

    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 ...

  • A Sampling Theorem for MLS Surfaces 

    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, ...

  • Conformal Alpha Shapes 

    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 ...

  • Normal Estimation for Point Clouds: A Comparison Study for a Voronoi Based Method 

    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 ...

  • Progressive Splatting 

    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, ...

  • Voronoi Rasterization of Sparse Point Sets 

    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 ...

  • High-Quality Surface Splatting on Today s GPUs 

    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 ...

  • Interactive Ray Tracing of Point-based Models 

    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 ...
