英文摘要：

Research the basic theory of extenics, the extension method, transforming bridge into. The virtual scene roaming algorithm of conventional detection method is complex with huge computation, this article puts forward method of decomposing and decentralizing collision detection of objects by the transforming bridge, and applies this method to the 3D Archive Project, reduce algorithm complexity, improve the efficiency and accuracy. Practice shows that, this method is feasible, and the system runs well.
