Automated Accessory Rigs for Layered 2D Character Illustrations
summary
Automated system builds directed acyclic graph linking each accessory to a single parent body or accessory layer and infers four constraint types (occlusion, single-point attachment, coincident boundaries, overlapping-region pins). It runs on layered artwork and datasets (OpenPeeps, Blush) and outputs per-accessory rigs that transfer body deformations like wider shoulders, breathing, and walk cycles; limitations include no physical secondary motion and no new geometry or texture synthesis, but generated rigs mostly preserve intended fits.
