BlitzGS: City-Scale Gaussian Splatting at Lightning Speed

Fei Zhu, Guoping Wang, Haojie Jin, Huishan Au, Mai Su, Meng Gai, Yilong Li, Yisong Chen, Zhongtao Wang

BlitzGS delivers order-of-magnitude faster city-scale 3D Gaussian Splatting training via index-parity GPU sharding, scheduled importance scoring, and LOD/importance culling while matching baseline quality.

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

On large-scale benchmarks, BlitzGS matches the rendering quality of recent large-scale baselines while delivering an order-of-magnitude speedup, training city-scale scenes in tens of minutes.

C2weakest assumption

That index-parity sharding combined with importance-based culling and LOD gates preserves visual quality equivalent to spatial baselines without introducing new artifacts or visibility errors on city-scale data.
