Gaussian Splatting Alignment (GSA) registers independently reconstructed 3D Gaussian Splatting models by estimating rotation, translation, and uniform scale. It uses viewpoint-guided features encoding part identity and location, followed by coarse correspondence matching and fine multi-view optimization. In six-category ShapeNet tests, it reports 2.45° relative rotation error for airplanes versus 136.32° for GaussReg; the tests measure rotation, not translation or scale.
