Abstract :
Now all kinds of 3D virtual worlds have been popular on Internet, but due to gigantic data of virtual scenes and limit network bandwidth, traditional Client/Server based downloading scheme has been bottleneck for a user to construct local virtual worlds swiftly. This paper proposes a parallel delivery scheme for large scale virtual scenes in a two-layer hybrid based P2P(Peer-to-Peer) overlay, in which server notification scheme is used to discover neighbors firstly, then an EMTFOI(Extended Multi-Tier Field of Interest) based culling algorithm is employed to cull needed virtual scenes. To compare with C/S based downloading scheme, this scheme realizes progressive delivery of virtual scenes in parallel with viewpoint movement in a multi-user environment and used bandwidth between nodes soundly.
