D71: Comparative Analysis of Spatial Partitioning Methods for Large-Scale, Real-time Crowd Simulation

Li,B., Mukundan,R.

Abstract:
Acceleration algorithms involving spatial partitioning methods are extensively used in crowd simulation for real-time collision avoidance. Memory and update costs become increasingly important as the crowd size becomes large. The paper presents a detailed analysis of the effectiveness of spatial subdivision data structures, specifically for large-scale crowd simulation. The results demonstrate that a regular grid data structure combined with an extended oriented bounding volume for crowd members can facilitate efficient updates necessary for real-time performance.
