SplatAnything: Gaussian Spacing Normalization for Feed-forward 3DGS across Arbitrary Scenes

SplatAnything addresses a limitation in feed-forward 3D Gaussian Splatting, where Gaussian spacing varies across scene scales and camera setups. It introduces Gaussian Spacing Normalization (GSNorm), which canonicalises a robust scene-level spacing statistic to give more consistent supervision for Gaussian prediction. The authors also build a benchmark spanning diverse datasets, input sparsity levels and extrapolated viewpoints, and report state-of-the-art results with the largest gains under large scene-scale and viewpoint variation.
