LUNA: LBS-Free Universal 3D Human Animation Model (ECCV 2026)

rsasaki0109 · x · 2026-08-10

Introduces LUNA, an LBS-free universal neural animation model. It directly maps diverse 2D controls like images, keypoints, and sketches into 3D Gaussian deformations, bypassing explicit body fitting. The core uses a transformer-based motion regressor to disentangle global rigid motion from local dynamics, and introduces hybrid supervision to resolve 2D-to-3D lifting ambiguities.
