Partial Matching of 3D Shapes with Priority-Driven Search
(The Eurographics Association, 2006)Priority-driven search is an algorithm for retrieving similar shapes from a large database of 3D objects. Given a query object and a database of target objects, all represented by sets of local 3D shape features, the ... -
Poisson Surface Reconstruction
(The Eurographics Association, 2006)We show that surface reconstruction from oriented points can be cast as a spatial Poisson problem. This Poisson formulation considers all the points at once, without resorting to heuristic spatial partitioning or blending, ... -
PriMo: Coupled Prisms for Intuitive Surface Modeling
(The Eurographics Association, 2006)We present a new method for 3D shape modeling that achieves intuitive and robust deformations by emulating physically plausible surface behavior inspired by thin shells and plates. The surface mesh is embedded in a layer ... -
Probabilistic Fingerprints for Shapes
(The Eurographics Association, 2006)We propose a new probabilistic framework for the efficient estimation of similarity between 3D shapes. Our framework is based on local shape signatures and is designed to allow for quick pruning of dissimilar shapes, while ... -
A Quadratic Bending Model for Inextensible Surfaces
(The Eurographics Association, 2006)Relating the intrinsic Laplacian to the mean curvature normal, we arrive at a model for bending of inextensible surfaces. Due to its constant Hessian, our isometric bending model reduces cloth simulation times up to three-fold. -
Reconstruction with Voronoi Centered Radial Basis Functions
(The Eurographics Association, 2006)We consider the problem of reconstructing a surface from scattered points sampled on a physical shape. The sampled shape is approximated as the zero level set of a function. This function is defined as a linear combination ... -
Rectangular Multi-Chart Geometry Images
(The Eurographics Association, 2006)Many mesh parameterization algorithms have focused on minimizing distortion and utilizing texture area, but few have addressed issues related to processing a signal on the mesh surface.We present an algorithm which partitions ... -
Reliable Implicit Surface Polygonization using Visibility Mapping
(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
(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
(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
(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
(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
(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 ...
