TopoGS: Topology-Aware Anchor Feature Aggregation for Large-Scale 3D Gaussian Splatting

TopoGS is a topology-aware anchor feature aggregation framework with two lightweight components that establishes bidirectional cross-level gradient pathways by fusing per-level context triplets with a residual MLP and applies soft weighting to accommodate varying topological sparsity.
