1. A method for providing scene data of a virtual world, the method comprising:
receiving a request for downloading said scene data from a content requesting party, wherein said request includes (i) information on an object group in said scene data and (ii) Level of Detail (LoD) information on an object in said object group, wherein scene data of said object includes a LoD model file corresponding to said object in said object group; packing LoD content of said object in said object group based on said information on said object group in said scene data and said LoD information on said object by:
acquiring said LoD model file corresponding to said object,extracting said LoD content designated by said LoD information on said object using said acquired LoD model file, andpacking, into a single HTTP package to be sent to said content requesting party, said extracted LoD content designated by said LoD information on said object by forming said extracted LoD content into a package data, wherein said package data includes a header and an object data, wherein said header records counts of objects in said object group, and wherein said object data comprises data of said object in said object group; and transmitting said packed LoD content corresponding to said object group to said content requesting party, wherein said transmitting further comprises:
transmitting a unique identifier of a package data to said content requesting party, wherein said package data is formed by said packed LoD content; andresponding to a request for downloading said package data by transmitting said packed LoD content corresponding to said object group to said content requesting party, wherein said request is made by said content requesting party, and wherein said request is made according to said unique identifier.
