The Planner Checked Collisions Inside Gaussian Splat Scenes

CollisionSplatting defines a probability-inspired distance measure that operates directly on standard 3D Gaussian Splatting scenes. The team integrated it with GPU-accelerated model-predictive and tree-search planners so collision costs can be combined with learned image-space rewards. The authors report collision classification on par with or better than representative baselines, higher checking throughput and lower graphics-memory use, plus real-world navigation and manipulation demonstrations. Exact tradeoffs depend on scene reconstruction quality and the selected conservatism setting.
