The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

This shift to a rapid registration paradigm delivers superior 3DGS completion performance across three distinct benchmarks, enhancing the quality and efficiency of various baselines and achieving new SOTA results.

C2weakest assumption

The synthesized 2D reference images are sufficiently plausible and geometrically consistent to be lifted into accurate metric-scale 3D primitives via the Stereo-Anchor mechanism without introducing new artifacts or scale errors.

C3one line summary

GSCompleter completes sparse 3D Gaussian Splatting scenes via a distillation-free generate-then-register pipeline using Stereo-Anchor lifting and Ray-Constrained Registration, delivering SOTA results on three benchmarks.
