    • Registration of Point Cloud Data from a Geometric Optimization Perspective 

      Mitra, Niloy J.; Gelfand, Natasha; Pottmann, Helmut; Guibas, Leonidas (The Eurographics Association, 2004)
      We propose a framework for pairwise registration of shapes represented by point cloud data (PCD). We assume that the points are sampled from a surface and formulate the problem of aligning two PCDs as a minimization of the ...

    • A Remeshing Approach to Multiresolution Modeling 

      Botsch, Mario; Kobbelt, Leif (The Eurographics Association, 2004)
      Providing a thorough mathematical foundation, multiresolution modeling is the standard approach for global surface deformations that preserve fine surface details in an intuitive and plausible manner. A given shape is ...

    • Seamless Texture Atlases 

      Purnomo, Budirijanto; Cohen, Jonathan D.; Kumar, Subodh (The Eurographics Association, 2004)
      Texture atlas parameterization provides an effective way to map a variety of color and data attributes from 2D texture domains onto polygonal surface meshes. However, the individual charts of such atlases are typically ...

    • Second Order Smoothness over Extraordinary Vertices 

      Loop, Charles (The Eurographics Association, 2004)
      Catmull & Clark subdivision is now a standard for smooth free-form surface modeling. These surfaces are everywhere curvature continuous except at points corresponding to vertices not incident on four edges. While the surface ...

    • Shape Segmentation Using Local Slippage Analysis 

      Gelfand, Natasha; Guibas, Leonidas J. (The Eurographics Association, 2004)
      We propose a method for segmentation of 3D scanned shapes into simple geometric parts. Given an input point cloud, our method computes a set of components which possess one or more slippable motions: rigid motions which, ...

    • Signal-Specialized Parameterization for Piecewise Linear Reconstruction 

      Tewari, Geetika; Snyder, John; Sander, Pedro V.; Gortler, Steven J.; Hoppe, Hugues (The Eurographics Association, 2004)
      We propose a metric for surface parameterization specialized to its signal that can be used to create more efficient, high-quality texture maps. Derived from Taylor expansion of signal error, our metric predicts the signal ...

    • Similarity-Based Surface Modelling Using Geodesic Fans 

      Zelinka, Steve; Garland, Michael (The Eurographics Association, 2004)
      We present several powerful new techniques for similarity-based modelling of surfaces using geodesic fans, a new framework for local surface comparison. Similarity-based surface modelling provides intelligent surface ...

    • Simplification and Improvement of Tetrahedral Models for Simulation 

      Cutler, B.; Dorsey, J.; McMillan, L. (The Eurographics Association, 2004)
      Most 3D mesh generation techniques require simplification and mesh improvement stages to prepare a tetrahedral model for efficient simulation. We have developed an algorithm that both reduces the number of tetrahedra in ...

    • Smooth Subdivision of Tetrahedral Meshes 

      Schaefer, S.; Hakenberg, J.; Warren, J. (The Eurographics Association, 2004)
      We describe a new subdivision scheme for unstructured tetrahedral meshes. Previous tetrahedral schemes based on generalizations of box splines have encoded arbitrary directional preferences in their associated subdivision ...

    • Spectral Surface Reconstruction From Noisy Point Clouds 

      Kolluri, Ravikrishna; Shewchuk, Jonathan Richard; O'Brien, James F. (The Eurographics Association, 2004)
      We introduce a noise-resistant algorithm for reconstructing a watertight surface from point cloud data. It forms a Delaunay tetrahedralization, then uses a variant of spectral graph partitioning to decide whether each ...

    • Symmetry Descriptors and 3D Shape Matching 

      Kazhdan, Michael; Funkhouser, Thomas; Rusinkiewicz, Szymon (The Eurographics Association, 2004)
      In this paper, we present the Symmetry Descriptors of a 3D model. This is a collection of spherical functions that describes the measure of a model's rotational and reflective symmetry with respect to every axis passing ...

    • Topology Preserving Surface Extraction Using Adaptive Subdivision 

      Varadhan, Gokul; Krishnan, Shankar; Sriram, TVN; Manocha, Dinesh (The Eurographics Association, 2004)
      We address the problem of computing a topology preserving isosurface from a volumetric grid using Marching Cubes for geometry processing applications. We present a novel topology preserving subdivision algorithm to generate ...

    • Two Algorithms for Fast Reclustering of Dynamic Meshed Surfaces 

      Carr, Nathan A.; Hart, John C. (The Eurographics Association, 2004)
      Numerous mesh algorithms such as parametrization, radiosity, and collision detection require the decomposition of meshes into a series of clusters. In this paper we present two novel approaches for maintaining mesh clusterings ...
