Research On Scene Simulation Technology Of University Campus

Campus scene simulation has always been a research hotspot in the field of virtual reality.The current virtual campus tour system has some problems in path planning,time consuming of scene loading,dynamic realistic simulation of scene and so on.This paper makes research and analysis on these problems.This paper takes the real scene of Yanta Campus of Xi ’an Shiyou University as the case study.The specific work is as follows: Firstly,function analysis of the system is carried out,function modules are designed and modules are developed.Secondly,the UAV tilt photography technology is used to build a three-dimensional campus scene.Then,using the idea of data paging to build the scene,multi-threading technology is used to optimize the loading analysis,to solve the problem that the scene loading occupies the computer memory and the loading time is too long.Finally,the specific planning of the scene roaming path is realized,and the pathfinding method suitable for the scene in this paper is studied.Two ways of autonomous roaming and automatic roaming are realized by using the navigation grid method and the idea of character action control,so as to simulate the experience of different scenes in the campus.A particle system was added to simulate a dynamic fountain to realize the combination of fluid scenery and natural scenery.In this paper,virtual reality technology is used to realize the construction of virtual campus scene,which can be combined with two ways of autonomous roaming and automatic roaming for scene roaming,optimize the scene loading,and realize dynamic scenes such as fountain simulation.Can show the campus style to the public,to attract excellent students to join the good help.
