Query: Fast Simulation of Crowd Collision Avoidance   Real-time large-scale crowd simulations with realistic behavior, are
important for many application areas. On CPUs, the ORCA pedestrian steering
model is often used for agent-based pedestrian simulations. This paper
introduces a technique for running the ORCA pedestrian steering model on the
GPU. Performance improvements of up to 30 times greater than a multi-core CPU
model are demonstrated. This improvement is achieved through a specialized
linear program solver on the GPU and spatial partitioning of information
sharing. This allows over 100,000 people to be simulated in real time (60
frames per second).
