Surface simplification using intrinsic error metrics

HTD Liu, M Gillespie, B Chislett, N Sharp… - ACM Transactions on …, 2023 - par.nsf.gov
This paper describes a method for fast simplification of surface meshes. Whereas past
methods focus on visual appearance, our goal is to solve equations on the surface. Hence …

Surface maps via adaptive triangulations

P Schmidt, D Pieper, L Kobbelt - Computer Graphics Forum, 2023 - Wiley Online Library
We present a new method to compute continuous and bijective maps (surface
homeomorphisms) between two or more genus‐0 triangle meshes. In contrast to previous …

A heat method for generalized signed distance

N Feng, K Crane - ACM Transactions on Graphics (TOG), 2024 - dl.acm.org
We introduce a method for approximating the signed distance function (SDF) of geometry
corrupted by holes, noise, or self-intersections. The method implicitly defines a completed …

[PDF][PDF] Winding Numbers on Discrete Surfaces.

N Feng, M Gillespie, K Crane - ACM Trans. Graph., 2023 - nzfeng.github.io
Basic Problem. Any collection of unbroken (ie, closed), oriented loops can be decomposed
into subsets that do and do not bound regions of a surface"(Figure 1). Informally, we wish to …

Geometry processing with intrinsic triangulations

N Sharp, M Gillespie, K Crane - SIGGRAPH'21: ACM SIGGRAPH 2021 …, 2021 - par.nsf.gov
This course provides a first introduction to intrinsic triangulations and their use in mesh
processing algorithms. As geometric data becomes more ubiquitous, eg, in applications …

ARAP Revisited Discretizing the Elastic Energy using Intrinsic Voronoi Cells

U Finnendahl, M Schwartz… - Computer Graphics Forum, 2023 - Wiley Online Library
Abstract As‐rigid‐as‐possible (ARAP) surface modelling is widely used for interactive
deformation of triangle meshes. We show that ARAP can be interpreted as minimizing a …

Optimized Dual‐Volumes for Tetrahedral Meshes

A Jacobson - Computer Graphics Forum, 2024 - Wiley Online Library
Constructing well‐behaved Laplacian and mass matrices is essential for tetrahedral mesh
processing. Unfortunately, the de facto standard linear finite elements exhibit bias on …

Mesh Parameterization Meets Intrinsic Triangulations

K Akalin, U Finnendahl… - Computer Graphics …, 2024 - Wiley Online Library
A parameterization of a triangle mesh is a realization in the plane so that all triangles have
positive signed area. Triangle mesh parameterizations are commonly computed by …

Robust Biharmonic Skinning Using Geometric Fields

A Dodik, V Sitzmann, J Solomon, O Stein - arxiv preprint arxiv:2406.00238, 2024 - arxiv.org
Skinning is a popular way to rig and deform characters for animation, to compute reduced-
order simulations, and to define features for geometry processing. Methods built on skinning …

Differentiable Geodesic Distance for Intrinsic Minimization on Triangle Meshes

Y Li, L Numerow, B Thomaszewski… - ACM Transactions on …, 2024 - dl.acm.org
Computing intrinsic distances on discrete surfaces is at the heart of many minimization
problems in geometry processing and beyond. Solving these problems is extremely …
