A Primal-to-Primal Discretization of Exterior Calculus on Polygonal Meshes
(The Eurographics Association, 2017)
Discrete exterior calculus (DEC) offers a coordinate-free discretization of exterior calculus especially suited for computations on curved spaces. We present an extended version of DEC on surface meshes formed by general ...
Localized Manifold Harmonics for Spectral Shape Analysis
(The Eurographics Association, 2017)
The use of Laplacian eigenfunctions is ubiquitous in a wide range of computer graphics and geometry processing applications. In particular, Laplacian eigenbases allow generalizing the classical Fourier analysis to manifolds. ...
PCR: A Geometric Cocktail for Triangulating Point Clouds Beautifully Without Angle Bounds
(The Eurographics Association, 2017)
Reconstructing a triangulated surface from a point cloud through a mesh growing algorithm is a difficult problem, in largely because they use bounds for the admissible dihedral angle to decide on the next triangle to be ...
