Campus Display And Interactive System Implementation Based On Unity3D And HTC Vive

With the gradual deepening of virtual reality applications,people are increasingly demanding the complexity and realism of the scene.At present,the simulation based on traditional technology can not meet the needs of visualization and true three-dimensional in complex environments.People want to build a more A virtual simulation environment with realistic visualization,ability to interact with virtual scenes,and creative ideas.Therefore,the research and application of 3D virtual interactive systems in complex environments has become a hot research topic of virtual simulation technology.This paper takes the design and development of campus 3D virtual interactive system as the main line,takes the real scene of Nanchang Aviation University campus as a research example,and uses 3ds Max as a modeling tool to complete the indoor and outdoor models in the 3D virtual campus scene.Based on the Unity3 D engine as the main development platform,combined with HTC Vive interactive device to complete the development and verification of the prototype system.The main contents of this article are as follows:(1)Completing the data collection of the overall terrain and building information of the campus of Nanchang Aviation University.Based on the analysis of the refined model of the virtual scene,combined with the modeling features and modeling requirements of the campus virtual environment,the tree level is built.Model method,3D visualization modeling software 3ds Max,drawing software Auto CAD to build 3D model,build 3D virtual scene,real-time display principle based on virtual reality scene,virtual scene optimization strategy,optimize the processing of the constructed virtual scene,realize realistic campus The indoor and outdoor scenes are finally simulated.(2)Based on the Unity3 D engine,the development and scene integration of the virtual campus system,using C# as the script development language,through the study of the virtual scene real-time rendering principle,the entity manipulation in the scene,real-time interaction and other key technologies,to achieve the campus overall scene tour System functions such as immersive interaction of typical indoor scene modules on campus.(3)Using HTC Vive as the interactive experience platform to realize the real-time autonomous conversion function of the camera perspective in the virtual campus system,and constructing the immersive space in the head-mounted display(HMD),combining the Lighthouse base station and Unity3 D to complete the user in the virtual scene.Immersive experience.Based on the roaming of the entire virtual scene,the interactive simulation based on the HTC Vive device in the campus indoor scene is emphasized.In the classroom module,the dynamic display of the student's personal information,the classroom scenario dialogue simulation,and the interaction of the multimedia video playback and pause are controlled through the handle interaction.Library module,the experiencer can experience reading,immersive experience book information retrieval simulation platform.The gym module has built a full immersive shooting training platform to achieve full-body shooting in realistic virtual scenes.The laboratory module implements a virtual chemical operation experience by using particle systems to simulate the combustion effects of chemical laboratory drugs.The realization of the above functions,get rid of the dependence on the mouse and keyboard device,and realize the immersive interactive experience effect of virtual reality through the call.The system is interactive,intuitive,convenient,and highly realistic and immersive.The system has achieved the expected functions,and the application has achieved the intended purpose in the publicity and display of the school.
