ATSplat: Compact Feed-forward 3D Gaussian Splatting with Adaptive Token Expansion
ATSplat is presented, a feed-forward 3DGS framework that restores the adaptive allocation capability of 3DGS optimization through Adaptive 3D Tokens, and achieves state-of-the-art rendering quality while reducing the number of Gaussians by more than $5.7\times compared with dense feed-forward 3DGS methods.
