Most solutions in a roaming system building are using three-dimensional graphics library drawing geometric structure to produce a target object. Although this technology has already been developed proficiently, the process is complex and time-consuming. Because of the inadequacies of this technique, a solution is proposed in this paper, and thus, the three-dimensional interactive ramble system of Southwest University of Science and Technology is established, based on VR-Platform by using 3ds Max modelling and scene pictures with auxiliary, which has not only the function of a three-dimensional navigational system, but can also display campus in a multi-position combined with animation.
