    • 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 ...
