The gaming user terminal 20 is preferably a portable mobile device such as a cell phone, tablet computer, palm game console, or the like. It will be appreciated that the gaming user terminal 20 may also be a desktop or notebook computer or the like. The game user terminal 20 may be connected to the three-dimensional game model data processing server 10 through a wireless or wired network.
