Design And Implementation Of Virtual Three-dimensional Digital Campus Roaming System Based On VR

With the continuous development of computer technology,virtual reality technology is also gradually developing.The virtual reality-based roaming system has been successfully applied in industrial simulation,urban planning,talent training,and distance education.This article takes the design and implementation of the virtual three-dimensional digital campus roaming system of Tianjin Normal University as an example.Based on the Unity3D development platform as the main development platform for the roaming system.HTC vive hardware platform for scene roaming system development.The 3D modeling technology of 3Ds Max is used to build a 3D model of a virtual walkthrough system.It solves the problems of poor scene setting,insufficient immersibility and slow model making in the virtual roaming system.The development of the virtual campus roaming system can be successfully implemented.The system realizes the immersive and three-dimensional virtual roaming of university campuses,which can meet the needs of school propaganda.This article mainly made the following:1.Create a 3D virtual scene.3Ds Max software is used to realize 3D modeling of real campus scenes,and modeling,enhancement of terrain,buildings,vegetation(grassland,trees)is achieved through MaxScripts script modeling technology,hair system modeling technology,and polygon modeling technology.The realism of the scene.2.Using Unity3D as a development platform to realize the development and scene integration of the virtual campus system,including model import,lighting addition,adding physical features for the object,and combining C#language development.3.Using the HTC vive as a hardware platform,real-time conversion of the camera view angle of the roaming system is realized,and an immersive space is constructed in a virtual reality head-mounted display(HMD),and the user's scene roaming is realized in combination with the Lighthouse base station and Unity3D.
