Limit Shapes - A Tool for Understanding Shape Differences and Variability in 3D Model Collections
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We propose a novel construction for extracting a central or limit shape in a shape collection, connected via a functional map network. Our approach is based on enriching the latent space induced by a functional map network ... -
On Evaluating Consensus in RANSAC Surface Registration
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Random Sample Consensus is a powerful paradigm that was successfully applied in various contexts, including Location Determination Problem, fundamental matrix estimation and global 3D surface registration, where many ... -
Parallel Globally Consistent Normal Orientation of Raw Unorganized Point Clouds
(The Eurographics Association and John Wiley & Sons Ltd., 2019)A mandatory component for many point set algorithms is the availability of consistently oriented vertex-normals (e.g. for surface reconstruction, feature detection, visualization). Previous orientation methods on meshes ... -
High Quality Refinable G-splines for Locally Quad-dominant Meshes With T-gons
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Polyhedral modeling and re-meshing algorithms use T-junctions to add or remove feature lines in a quadrilateral mesh. In many ways this is akin to adaptive knot insertion in a tensor-product spline, but differs in that the ... -
Feature Preserving Octree-Based Hexahedral Meshing
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We propose an octree-based algorithm to tessellate the interior of a closed surface with hexahedral cells. The generated hexahedral mesh (1) explicitly preserves sharp features of the original input, (2) has a maximal, ... -
Unsupervised Cycle-consistent Deformation for Shape Matching
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We propose a self-supervised approach to deep surface deformation. Given a pair of shapes, our algorithm directly predicts a parametric transformation from one shape to the other respecting correspondences. Our insight is ... -
Point Pattern Synthesis via Irregular Convolution
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Point pattern synthesis is a fundamental tool with various applications in computer graphics. To synthesize a point pattern, some techniques have taken an example-based approach, where the user provides a small exemplar ... -
A Convolutional Decoder for Point Clouds using Adaptive Instance Normalization
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Automatic synthesis of high quality 3D shapes is an ongoing and challenging area of research. While several data-driven methods have been proposed that make use of neural networks to generate 3D shapes, none of them reach ... -
Structural Design Using Laplacian Shells
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We introduce a method to design lightweight shell objects that are structurally robust under the external forces they may experience during use. Given an input 3D model and a general description of the external forces, our ... -
A Family of Barycentric Coordinates for Co-Dimension 1 Manifolds with Simplicial Facets
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We construct a family of barycentric coordinates for 2D shapes including non-convex shapes, shapes with boundaries, and skeletons. Furthermore, we extend these coordinates to 3D and arbitrary dimension. Our approach modifies ... -
Hierarchical Functional Maps between Subdivision Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We propose a novel approach for computing correspondences between subdivision surfaces with different control polygons. Our main observation is that the multi-resolution spectral basis functions that are often used for ... -
Dense Point-to-Point Correspondences Between Genus-Zero Shapes
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We describe a novel approach that addresses the problem of establishing correspondences between non-rigidly deformed shapes by performing the registration over the unit sphere. In a pre-processing step, each shape is ... -
Structured Regularization of Functional Map Computations
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We consider the problem of non-rigid shape matching using the functional map framework. Specifically, we analyze a commonly used approach for regularizing functional maps, which consists in penalizing the failure of the ... -
Consistent Shape Matching via Coupled Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We propose a new method for computing accurate point-to-point mappings between a pair of triangle meshes given imperfect initial correspondences. Unlike the majority of existing techniques, we optimize for a map while ... -
Divergence-Free Shape Correspondence by Deformation
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a novel approach for solving the correspondence problem between a given pair of input shapes with non-rigid, nearly isometric pose difference. Our method alternates between calculating a deformation field and a ... -
