Differential operators are widely used in geometry processing for problem domains like spectral shape analysis, data interpolation, parametrization and mapping, and meshing. In addition to the ubiquitous cotangent Laplacian, anisotropic second‐order operators, as well as higher‐order operators such as the Bilaplacian, have been discretized for specialized applications. In this paper, we study a class of operators that generalizes the fourth‐order Bilaplacian to support anisotropic behavior. The…

Algebraic Representations for Volumetric Frame Fields
TLDR
This work describes the space of octahedral frames in the language of differential and algebraic geometry and suggests computing frame fields via manifold-based optimization algorithms; it is shown that these algorithms efficiently produce high-quality fields while maintaining stability and smoothness.
An Operator Approach to Tangent Vector Field Processing
TLDR
This paper argues that vector fields can also be naturally viewed as operators whose domain and range are functions defined on the mesh, and leads to the characterization of vector field properties through commutativity with other operators such as the Laplace‐Beltrami and symmetry operators.
Mixed Finite Elements for Variational Surface Modeling
TLDR
This paper explores discretizations of common geometric PDEs on meshes using mixed finite elements, where additional variables for the derivatives in the problem are introduced.
An Approach to Quad Meshing Based on Harmonic Cross-Valued Maps and the Ginzburg-Landau Theory
TLDR
This work makes the observation that cross field design for two-dimensional quad meshing is related to the well-known Ginzburg-Landau problem from mathematical physics, and proves that this procedure can be used to produce a cross field whose separatrices partition the domain into four sided regions.
Natural Boundary Conditions for Smoothing in Geometry Processing
TLDR
This work proposes using the squared Frobenius norm of the Hessian as a smoothness energy to model free boundaries where the shape of the boundary should not bias the solution locally.
Spectral surface quadrangulation
TLDR
This work describes a fundamentally new approach to the quadrangulation of manifold polygon meshes using Laplacian eigenfunctions, the natural harmonics of the surface, to construct a well-shaped quadrilateral mesh with very few extraordinary vertices.
Spectral surface quadrangulation
Resampling raw surface meshes is one of the most fundamental operations used by nearly all digital geometry processing systems. The vast majority of this work has focused on triangular remeshing, yet
Boundary element octahedral fields in volumes
TLDR
This article presents an algorithm for computing “octahedral” fields of orthogonal directions within a volume via the boundary element method (BEM), continuously assigning frames to points in the interior from only a triangle mesh discretization of the boundary.
Implicit fairing of irregular meshes using diffusion and curvature flow
TLDR
Methods to rapidly remove rough features from irregularly triangulated data intended to portray a smooth surface are developed and it is proved that these curvature and Laplacian operators have several mathematically-desirable qualities that improve the appearance of the resulting surface.
A mixed finite element method with piecewise linear elements for the biharmonic equation on surfaces
TLDR
This work provides a convergence proof of discrete solutions to the corresponding smooth solution of the biharmonic equation on polyhedral surfaces and obtains convergence rates that are identical to the ones known for the planar setting.
