摘要：

Crowd　simulation　plays　an　important　role　in　virtual　reality　and　it　has　been　widely　applied　in　various　fields.　The　research　always　focuses　on　the　simulation　efficiency　and　rendering.　We　construct　a　real-time　crowd　simulation　system　with　different　methods　based　on　parallel　architecture.　In　this　paper,　we　compare　and　analyze　their　different　simulation　efficiencies　through　the　experiments.　The　method　in　combination　of　CPU　and　GPU　with　parallel　computing　on　multi-core　CPUs　can　get　the　highest　efficiency　in　our　simulation　system.　The　GPU　method　is　suitable　for　the　crowd　simulation　system　without　frequent　data　transmission　between　CPU　and　GPU　and　a　mass　of　branch　statements　and　texture　look-ups.　©　2012　IEEE.
