Developable Surfaces from Arbitrary Sketched Boundaries
(The Eurographics Association, 2007)We present a method for extracting a hierarchical, rigid skeleton from a set of example poses. We then use this skeleton to not only reproduce the example poses, but create new deformations in the same style as the examples. ... -
Linear Angle Based Parameterization
(The Eurographics Association, 2007)In the field of mesh parameterization, the impact of angular and boundary distortion on parameterization quality have brought forward the need for robust and efficient free boundary angle preserving methods. One of the ... -
Example-Based Skeleton Extraction
(The Eurographics Association, 2007)We present a method for extracting a hierarchical, rigid skeleton from a set of example poses. We then use this skeleton to not only reproduce the example poses, but create new deformations in the same style as the examples. ... -
Unconstrained Isosurface Extraction on Arbitrary Octrees
(The Eurographics Association, 2007)This paper presents a novel algorithm for generating a watertight level-set from an octree. We show that the level- set can be efficiently extracted regardless of the topology of the octree or the values assigned to the ... -
GPU-assisted Positive Mean Value Coordinates for Mesh Deformations
(The Eurographics Association, 2007)In this paper we introduce positive mean value coordinates (PMVC) for mesh deformation. Following the observations of Joshi et al. [JMD*07] we show the advantage of having positive coordinates. The control points of the ... -
Triangulations with Locally Optimal Steiner Points
(The Eurographics Association, 2007)We present two new Delaunay refinement algorithms, the second an extension of the first. For a given input domain (a set of points in the plane or a planar straight line graph), and a threshold angle a, the Delaunay ... -
As-Rigid-As-Possible Surface Modeling
(The Eurographics Association, 2007)Modeling tasks, such as surface deformation and editing, can be analyzed by observing the local behavior of the surface. We argue that defining a modeling operation by asking for rigidity of the local transformations is ... -
Elastic Secondary Deformations by Vector Field Integration
(The Eurographics Association, 2007)We present an approach for elastic secondary deformations of shapes described as triangular meshes. The deformations are steered by the simulation of a low number of simple mass-spring sets. The result of this simulation ... -
Multilevel Streaming for Out-of-Core Surface Reconstruction
(The Eurographics Association, 2007)Reconstruction of surfaces from huge collections of scanned points often requires out-of-core techniques, and most such techniques involve local computations that are not resilient to data errors. We show that a Poisson-based ... -
Shape Reconstruction from Unorganized Cross-sections
(The Eurographics Association, 2007)In this paper, we consider the problem of reconstructing a shape from unorganized cross-sections. The main motivation for this problem comes from medical imaging applications where cross-sections of human organs are obtained ... -
A Streaming Algorithm for Surface Reconstruction
(The Eurographics Association, 2007)We present a streaming algorithm for reconstructing closed surfaces from large non-uniform point sets based on a geometric convection technique. Assuming that the sample points are organized into slices stacked along one ... -
Reconstruction of Deforming Geometry from Time-Varying Point Clouds
(The Eurographics Association, 2007)In this paper, we describe a system for the reconstruction of deforming geometry from a time sequence of unstructured, noisy point clouds, as produced by recent real-time range scanning devices. Our technique reconstructs ... -
Data-Dependent MLS for Faithful Surface Approximation
(The Eurographics Association, 2007)In this paper we present a high-fidelity surface approximation technique that aims at a faithful reconstruction of piecewise-smooth surfaces from a scattered point set. The presented method builds on the Moving Least-Squares ... -
Voronoi-based Variational Reconstruction of Unoriented Point Sets
(The Eurographics Association, 2007)We introduce an algorithm for reconstructing watertight surfaces from unoriented point sets. Using the Voronoi diagram of the input point set, we deduce a tensor field whose principal axes and eccentricities locally represent ... -
Discrete Laplace operators: No free lunch
(The Eurographics Association, 2007)Discrete Laplace operators are ubiquitous in applications spanning geometric modeling to simulation. For robustness and efficiency, many applications require discrete operators that retain key structural properties inherent ... -
Focal Surfaces of Discrete Geometry
(The Eurographics Association, 2007)The differential geometry of smooth three-dimensional surfaces can be interpreted from one of two perspectives: in terms of oriented frames located on the surface, or in terms of a pair of associated focal surfaces. These ... -
Robust Statistical Estimation of Curvature on Discretized Surfaces
(The Eurographics Association, 2007)A robust statistics approach to curvature estimation on discretely sampled surfaces, namely polygon meshes and point clouds, is presented. The method exhibits accuracy, stability and consistency even for noisy, non-uniformly ... -
An Image Processing Approach to Surface Matching
(The Eurographics Association, 2005)Establishing a correspondence between two surfaces is a basic ingredient in many geometry processing applications. Existing approaches, which attempt to match two meshes directly in 3D, can be cumbersome to implement and ... -
Multiscale Features for Approximate Alignment of Point-based Surfaces
(The Eurographics Association, 2005)We introduce a novel method for approximate alignment of point-based surfaces. Our approach is based on detecting a set of salient feature points using a scale-space representation. For each feature point we compute a ... -
Global Registration of Multiple 3D Point Sets via Optimization-on-a-Manifold
(The Eurographics Association, 2005)We propose a novel algorithm to register multiple 3D point sets within a common reference frame using a manifold optimization approach. The point sets are obtained with multiple laser scanners or a mobile scanner. Unlike ...
