To solve this problem, lightweight framework of Jinggangshan virtual real tourism system is constructed. Such key technologies as lightweight technology of 3D virtual scenes is researched. At the same time, such technologies as virtual roaming interactivity and modeling intelligent virtual dragoman are integrated in the system. In addition, important steps including invoking method of Web3D engine and lightweight script programs and constructing Cloud storage transmission platform are essential to
