:: PSCrowd

PSCrowd is a library to support large crowd/flock simulations on PLAYSTATION®3 or other Cell-based systems. The crowds are modeled as interacting (Lagrangian) particle systems. PSCrowd divides up the simulation work and distributes it across any number of SPUs. Demos provided with PSCrowd simulate and display simple crowds of up to 15,000 individuals at 60 frames per second.
