Study defines when 3D Gaussian Splatting recovers real surfaces

This study analyzes when 3D Gaussian Splatting recovers true scene surfaces versus overfitting view-dependent appearance. It establishes an identifiability window: if angular capacity is bounded, surface-consistent solutions are preferred; if unrestricted, incorrect opaque billboard geometries can perfectly explain images. Synthetic stress tests confirm billboard failures emerge at high angular capacities.
