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…
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…
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…
