• 3D Reconstruction Using Labeled Image Regions 

  Ziegler, Remo; Matusik, Wojciech; Pfister, Hanspeter; McMillan, Leonard (The Eurographics Association, 2003)

  In this paper we present a novel algorithm for reconstructing 3D scenes from a set of images. The user defines a set of polygonal regions with corresponding labels in each image using familiar 2D photo-editing tools. Our ...

• Approximate Implicitization Via Curve Fitting 

  Wurm, E.; Jüttler, B. (The Eurographics Association, 2003)

  We discuss methods for fitting implicitly defined (e.g. piecewise algebraic) curves to scattered data, which may contain problematic regions, such as edges, cusps or vertices. As the main idea, we construct a bivariate ...

• Approximating and Intersecting Surfaces from Points 

  Adamson, Anders; Alexa, Marc (The Eurographics Association, 2003)

  Point sets become an increasingly popular shape representation. Most shape processing and rendering tasks require the approximation of a continuous surface from the point data. We present a surface approximation that is ...

• 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 ...

• 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 ...

• 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 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 ...

• Estimating Differential Quantities Using Polynomial Fitting of Osculating Jets 

  Cazals, F.; Pouget, M. (The Eurographics Association, 2003)

  This paper addresses the pointwise estimation of differential properties of a smooth manifold S -a curve in the plane or a surface in 3D- assuming a point cloud sampled over S is provided. The method consists of fitting ...

• 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 ...

• 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 ...

• 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 ...

• 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 ...

• 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, ...

• Efficient Max-Norm Distance Computation and Reliable Voxelization 

  Varadhan, Gokul; Krishnan, Shankar; Kim, Young J.; Diggavi, Suhas; Manocha, Dinesh (The Eurographics Association, 2003)

  We present techniques to efficiently compute the distance under max-norm between a point and a wide class of geometric primitives. We formulate the distance computation as an optimization problem and use this framework to ...

• 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 ...

• 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 ...

• CLODs: Dual Hierarchies for Multiresolution Collision Detection 

  Otaduy, Miguel A.; Lin, Ming C. (The Eurographics Association, 2003)

  We present "contact levels of detail" (CLOD), a novel concept for multiresolution collision detection. Given a polyhedral model, our algorithm automatically builds a "dual hierarchy", both a multiresolution representation ...

• 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 ...

• Edge-Sharpener: Recovering sharp features in triangulations of non-adaptively re-meshed surfaces 

  Attene, Marco; Falcidieno, Bianca; Rossignac, Jarek; Spagnuolo, Michela (The Eurographics Association, 2003)

  3D scanners, iso-surface extraction procedures, and several recent geometric compression schemes sample surfaces of 3D shapes in a regular fashion, without any attempt to align the samples with the sharp edges and corners ...

• A concise b-rep data structure for stratified subanalytic objects 

  Gomes, Abel J.P. (The Eurographics Association, 2003)

  Current geometric kernels suffer from poor abstraction and design of their data structures. In part, this is due to the lack of a general mathematical framework for geometric modelling and processing. As a result, there ...
