AsRigidAsPossible 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 ... 
Bayesian Surface Reconstruction via Iterative Scan Alignment to an Optimized Prototype
(The Eurographics Association, 2007)This paper introduces a novel technique for joint surface reconstruction and registration. Given a set of roughly aligned noisy point clouds, it outputs a noisefree and watertight solid model. The basic idea of the new ... 
Constraintbased Fairing of Surface Meshes
(The Eurographics Association, 2007)We propose a constraintbased method for the fairing of surface meshes. The main feature of our approach is that the resulting smoothed surface remains within a prescribed distance to the input mesh. For example, specifying ... 
DataDependent MLS for Faithful Surface Approximation
(The Eurographics Association, 2007)In this paper we present a highfidelity surface approximation technique that aims at a faithful reconstruction of piecewisesmooth surfaces from a scattered point set. The presented method builds on the Moving LeastSquares ... 
Delaunay Mesh Construction
(The Eurographics Association, 2007)We present algorithms to produce Delaunay meshes from arbitrary triangle meshes by edge flipping and geometrypreserving refinement and prove their correctness. In particular we show that edge flipping serves to reduce mesh ... 
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. ... 
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 ... 
Dynamic Geometry Registration
(The Eurographics Association, 2007)We propose an algorithm that performs registration of large sets of unstructured point clouds of moving and deforming objects without computing correspondences. Given as input a set of frames with dense spatial and temporal ... 
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 massspring sets. The result of this simulation ... 
ExampleBased 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. ... 
Fast Normal Vector Compression with Bounded Error
(The Eurographics Association, 2007)We present two methods for lossy compression of normal vectors through quantization using base polyhedra. The first revisits subdivisionbased quantization. The second uses fixedprecision barycentric coordinates. For ... 
Focal Surfaces of Discrete Geometry
(The Eurographics Association, 2007)The differential geometry of smooth threedimensional 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 ... 
Generalized Surface Flows for Mesh Processing
(The Eurographics Association, 2007)Geometric flows are ubiquitous in mesh processing. Curve and surface evolutions based on functional minimization have been used in the context of surface diffusion, denoising, shape optimization, minimal surfaces, and ... 
GPUassisted 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 ... 
LaplaceBeltrami Eigenfunctions for Deformation Invariant Shape Representation
(The Eurographics Association, 2007)A deformation invariant representation of surfaces, the GPS embedding, is introduced using the eigenvalues and eigenfunctions of the LaplaceBeltrami differential operator. Notably, since the definition of the GPS embedding ... 
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 ... 
Multilevel Streaming for OutofCore Surface Reconstruction
(The Eurographics Association, 2007)Reconstruction of surfaces from huge collections of scanned points often requires outofcore techniques, and most such techniques involve local computations that are not resilient to data errors. We show that a Poissonbased ... 
Reconstruction of Deforming Geometry from TimeVarying 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 realtime range scanning devices. Our technique reconstructs ... 
Ridge Based Curve and Surface Reconstruction
(The Eurographics Association, 2007)This paper presents a new method for reconstructing curves and surfaces from unstructured point clouds, allowing for noise in the data as well as inhomogeneous distribution of the point set. It is based on the observation ... 
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, nonuniformly ...
