Proximity Queries on Point Clouds using Rapid Construction Path Oracle
Summary: Proposes a (1+ε)-approximate shortest-path oracle for point clouds that stores pairwise POI paths, enabling fast shortest-path, kNN, and range queries. Outperforms the best-known TIN oracle: up to 390×/30×/6× (POIs given) and 500×/140×/50× (POIs not given); kNN and range queries up to 100× faster. (summarized by gpt-5-nano on Feb 09 2026)
