Social.Wiki: A Web Held in Common
Theia Henderson, Carmel Schare, Ana Dodik +4
Many of the websites people depend on have owners whose interests are not fully aligned with their users. We address the root of this problem by presenting a reimagining of the web…
Tangent Blow-Ups for Processing Non-Manifold Geometry
Alice Petrov, Mohammad Sina Nabizadeh, Ana Dodik +1
Many geometry processing pipelines implicitly assume their input data is a manifold, or is sampled from one, with a unique tangent plane at every point. Geometric data, however, ro…
Meschers: Geometry Processing of Impossible Objects
Ana Dodik, Isabella Yu, Kartik Chandra +4
Impossible objects, geometric constructions that humans can perceive but that cannot exist in real life, have been a topic of intrigue in visual arts, perception, and graphics, yet…
Synthetic Sociality: How Generative Models Privatize the Social Fabric
Ana Dodik, Moira Weigel
We put forth a critical theoretical framework for analyzing generative models both descriptively and normatively. Our thesis is that generative models automate the production not o…
Iskra: A System for Inverse Geometry Processing
Ana Dodik, Ahmed H. Mahmoud, Justin Solomon
We propose a system for differentiating through solutions to geometry processing problems. Our system differentiates a broad class of geometric algorithms, exploiting existing fast…
Fast Sparse Matrix Permutation for Mesh-Based Direct Solvers
Behrooz Zarebavami, Ahmed H. Mahmoud, Ana Dodik +5
We present a fast sparse matrix permutation algorithm tailored to linear systems arising from triangle meshes. Our approach produces nested-dissection-style permutations while sign…
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…
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…
Sex and Gender in the Computer Graphics Research Literature
Ana Dodik, Silvia Sellán, Theodore Kim +1
We survey the treatment of sex and gender in the Computer Graphics research literature from an algorithmic fairness perspective. The established practices on the use of gender and…
Path Guiding Using Spatio-Directional Mixture Models
Ana Dodik, Marios Papas, Cengiz Öztireli +1
We propose a learning-based method for light-path construction in path tracing algorithms, which iteratively optimizes and samples from what we refer to as spatio-directional Gauss…
