    • Reliable Implicit Surface Polygonization using Visibility Mapping 

      Varadhan, Gokul; Krishnan, Shankar; Zhang, Liangjun; Manocha, Dinesh (The Eurographics Association, 2006)
      We present a new algorithm to compute a topologically and geometrically accurate triangulation of an implicit surface. Our approach uses spatial subdivision techniques to decompose a manifold implicit surface into star-shaped ...

    • Robust Principal Curvatures on Multiple Scales 

      Yang, Yong-Liang; Lai, Yu-Kun; Hu, Shi-Min; Pottmann, Helmut (The Eurographics Association, 2006)
      Geometry processing algorithms often require the robust extraction of curvature information. We propose to achieve this with principal component analysis (PCA) of local neighborhoods, defined via spherical kernels centered ...

    • Robust Reconstruction of Watertight 3D Models from Non-uniformly Sampled Point Clouds Without Normal Information 

      Hornung, Alexander; Kobbelt, Leif (The Eurographics Association, 2006)
      We present a new volumetric method for reconstructing watertight triangle meshes from arbitrary, unoriented point clouds. While previous techniques usually reconstruct surfaces as the zero level-set of a signed distance ...

    • Selectively Refinable Subdivision Meshes 

      Puppo, Enrico (The Eurographics Association, 2006)
      We introduce RGB triangulations, an extension of red-green triangulations that can support selective refinement over subdivision meshes generated through quadrisection of triangles. Our purpose is to define a mechanism ...

    • Size Functions for 3D Shape Retrieval 

      Biasotti, S.; Giorgi, D.; Spagnuolo, M.; Falcidieno, B. (The Eurographics Association, 2006)
      This paper sketches a technique for 3D model retrieval built on size functions, a mathematical tool to compare shapes. Size functions are introduced for the first time to discriminate among 3D objects, through the proposal ...

    • Spherical Barycentric Coordinates 

      Langer, Torsten; Belyaev, Alexander; Seidel, Hans-Peter (The Eurographics Association, 2006)
      We develop spherical barycentric coordinates. Analogous to classical, planar barycentric coordinates that describe the positions of points in a plane with respect to the vertices of a given planar polygon, spherical ...
