    • Filling Holes in Meshes 

      Liepa, Peter (The Eurographics Association, 2003)
      We describe a method for filling holes in unstructured triangular meshes. The resulting patching meshes interpolate the shape and density of the surrounding mesh. Our methods work with arbitrary holes in oriented connected ...

    • A Geometric Convection Approach of 3-D Reconstruction 

      Chaine, Raphaëlle (The Eurographics Association, 2003)
      This paper introduces a fast and efficient algorithm for surface reconstruction. As many algorithms of this kind, it produces a piecewise linear approximation of a surface S from a finite, sufficiently dense, subset of its ...

    • A Geometric Database for Gene Expression Data 

      Ju, Tao; Warren, Joe; Eichele, Gregor; Thaller, Christina; Chiu, Wah; Carson, James (The Eurographics Association, 2003)
      As the logical next step after sequencing the mouse genome, biologists have developed laboratory methods for rapidly determining where each of the 30K genes in the mouse genome is synthesizing protein. Applying these methods ...

    • Geometry Compression of Normal Meshes Using Rate-Distortion Algorithms 

      Lavu, Sridhar; Choi, Hyeokho; Baraniuk, Richard (The Eurographics Association, 2003)
      We propose a new rate-distortion based algorithm for compressing 3D surface geometry represented using triangular normal meshes. We apply the Estimation-Quantization (EQ) algorithm to compress normal mesh wavelet coefficients. ...

    • Global Conformal Surface Parameterization 

      Gu, Xianfeng; Yau, Shing-Tung (The Eurographics Association, 2003)
      We solve the problem of computing global conformal parameterizations for surfaces with nontrivial topologies. The parameterization is global in the sense that it preserves the conformality everywhere except for a few points, ...

    • High-Pass Quantization for Mesh Encoding 

      Sorkine, Olga; Cohen-Or, Daniel; Toledo, Sivan (The Eurographics Association, 2003)
      Any quantization introduces errors. An important question is how to suppress their visual effect. In this paper we present a new quantization method for the geometry of 3D meshes, which enables aggressive quantization ...

    • Mesh Forging: Editing of 3D-Meshes Using Implicitly Defined Occluders 

      Bendels, G. H.; Klein, R. (The Eurographics Association, 2003)
      In recent years the ease of use and the flexibility in the editing process shifted into focus in modelling and animation applications. In this spirit we present a 3D mesh editing method that is similar to the simple ...

    • Multi-Chart Geometry Images 

      Sander, P. V.; Wood, Z. J.; Gortler, S. J.; Snyder, J.; Hoppe, H. (The Eurographics Association, 2003)
      We introduce multi-chart geometry images, a new representation for arbitrary surfaces. It is created by resampling a surface onto a regular 2D grid. Whereas the original scheme of Gu et al. maps the entire surface onto a ...

    • Provably Good Surface Sampling and Approximation 

      Boissonnat, J-D.; Oudot, S. (The Eurographics Association, 2003)
      We present an algorithm for meshing surfaces that is a simple adaptation of a greedy "farthest point" technique proposed by Chew. Given a surface S, it progressively adds points on S and updates the 3-dimensional Delaunay ...

    • Rotation Invariant Spherical Harmonic Representation of 3D Shape Descriptors 

      Kazhdan, Michael; Funkhouser, Thomas; Rusinkiewicz, Szymon (The Eurographics Association, 2003)
      One of the challenges in 3D shape matching arises from the fact that in many applications, models should be considered to be the same if they differ by a rotation. Consequently, when comparing two models, a similarity ...

    • A scalable data structure for three-dimensional non-manifold objects 

      Floriani, Leila De; Hui, Annie (The Eurographics Association, 2003)
      In this paper, we address the problem of representing and manipulating non-manifold, mixed-dimensional objects described by three-dimensional simplicial complexes embedded in the 3D Euclidean space. We describe the design ...

    • Simple Silhouettes for Complex Surfaces 

      Kirsanov, D.; Sander, P. V.; Gortler, S. J. (The Eurographics Association, 2003)
      Complex meshes tend to have intricate, detailed silhouettes. This paper proposes two algorithms for extracting a simpler, approximate silhouette from a high-resolution model. Our methods preserve the important features of ...

    • Smooth Geometry Images 

      Losasso, F.; Hoppe, H.; Schaefer, S.; Warren, J. (The Eurographics Association, 2003)
      Previous parametric representations of smooth genus-zero surfaces require a collection of abutting patches (e.g. splines, NURBS, recursively subdivided polygons). We introduce a simple construction for these surfaces using ...

    • Statistical Point Geometry 

      Kalaiah, Aravind; Varshney, Amitabh (The Eurographics Association, 2003)
      We propose a scheme for modeling point sample geometry with statistical analysis. In our scheme we depart from the current schemes that deterministically represent the attributes of each point sample. We show how the ...

    • Stellar Subdivision Grammars 

      Velho, Luiz (The Eurographics Association, 2003)
      In this paper we develop a new description for subdivision surfaces based on a graph grammar formalism. Subdivision schemes are specified by a context sensitive grammar in which production rules represent topological and ...
