RADmesh: Remesh-Aware Mesh Deformation
Nam Anh Dinh, Itai Lang, Oded Stein +1
We propose a remeshing-enhanced method for generatively deforming shapes with visual losses. It is intuitive that sufficiently drastic deformations of a mesh without changing its t…
Dual Contouring of Signed Distance Data
Xiana Carrera, Ningna Wang, Christopher Batty +2
We propose an algorithm to reconstruct explicit polygonal meshes from discretely sampled Signed Distance Function (SDF) data, which is especially effective at recovering sharp feat…
PINNsur: Physics-Informed Neural Networks for PDEs on Curved Surfaces
Pranav Jain, Navami Kairanda, Peter Yichen Chen +1
Partial differential equations (PDEs) on surfaces are fundamental to scientific computing and geometry processing. A popular approach to solving PDEs on surfaces is the finite elem…
Look Both Ways Before You Cross: Lifting Cross Fields From 2D Visual Priors
Dale Decatur, Jacob Serfaty, Oded Stein +2
We present CrossLift, a technique for computing cross fields on meshes guided by visual features in images. We leverage powerful text-to-image priors that are capable of synthesizi…
SpUDD: Superpower Contouring of Unsigned Distance Data
Ningna Wang, Xiana Carrera, Christopher Batty +2
Unsigned distance functions offer a powerful and flexible implicit surface representation that, unlike their signed counterparts, allow for surfaces that are open, non-orientable,…
Greed for the Spheres: A Signed Distance Interpolation Method
Letao Chen, Sanju Mupparaju, Christopher Batty +2
We propose a method to interpolate Signed Distance Function (SDF) data from a discrete set of samples. Unlike prior work, our approach ensures that the new SDF data values are full…
Phong-Rodrigues Extrinsic Vector-Field Processing
Hongyi Liu, Oded Stein, Amir Vaxman +2
We introduce a new extrinsic discretization of tangent vector fields on triangle meshes that is continuous, with bounded derivatives that are continuous almost everywhere, supporti…
Geometry in Style: 3D Stylization via Surface Normal Deformation
Nam Anh Dinh, Itai Lang, Hyunwoo Kim +2
We present Geometry in Style, a new method for identity-preserving mesh stylization. Existing techniques either adhere to the original shape through overly restrictive deformations…
Robust Biharmonic Skinning Using Geometric Fields
Ana Dodik, Vincent Sitzmann, Justin Solomon +1
Bounded bihramonic weights are a popular tool used to rig and deform characters for animation, to compute reduced-order simulations, and to define feature descriptors for geometry…
A Framework for Solving Parabolic Partial Differential Equations on Discrete Domains
Leticia Mattos Da Silva, Oded Stein, Justin Solomon
We introduce a framework for solving a class of parabolic partial differential equations on triangle mesh surfaces, including the Hamilton-Jacobi equation and the Fokker-Planck equ…
An Adaptive Fast-Multipole-Accelerated Hybrid Boundary Integral Equation Method for Accurate Diffusion Curves
Seungbae Bang, Kirill Serkh, Oded Stein +1
In theory, diffusion curves promise complex color gradations for infinite-resolution vector graphics. In practice, existing realizations suffer from poor scaling, discretization ar…
Variational Barycentric Coordinates
Ana Dodik, Oded Stein, Vincent Sitzmann +1
We propose a variational technique to optimize for generalized barycentric coordinates that offers additional control compared to existing models. Prior work represents barycentric…
The Effect of Smoothing on the Interpretation of Time Series Data: A COVID-19 Case Study
Oded Stein, Alec Jacobson, Fanny Chevalier
We conduct a controlled crowd-sourced experiment of COVID-19 case data visualization to study if and how different plotting methods, time windows, and the nature of the data influe…
Reach For the Spheres: Tangency-Aware Surface Reconstruction of SDFs
Silvia Sellán, Christopher Batty, Oded Stein
Signed distance fields (SDFs) are a widely used implicit surface representation, with broad applications in computer graphics, computer vision, and applied mathematics. To reconstr…
