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 ...
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 ...
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 ...
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 ...
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, ...
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 ...
