Performance Evaluation of Spatial Hashing with Temporal Coherence for Particle Neighbor Search

This paper demonstrates that while exploiting temporal coherence to incrementally maintain spatial hash tables can significantly accelerate particle neighbor searches in coherent motion scenarios, its performance advantage is highly sensitive to particle movement and table load, often making full reconstruction the safer choice when these factors exceed specific thresholds.
