Development And Implementation Of Campus Scene Based On Virtual Reality Technology

The research and implementation of campus scene based on virtual reality technology has become a hot spot in education and teaching.With the widespread application of information technology and artificial intelligence technology,the study of campus simulation scene based on virtual reality technology has important application value and social significance.Virtual reality technology is applied to campus scenes to make the whole scene immersive,interactive and imaginative.The technology virtualizes the campus scene,immerses the characters in it to simulate human senses and realizes human-computer interaction through command operation.Virtual campus technology builds campus scenes through virtual reality technology,which can make up for the time-consuming and laborious defects of field inspection and paper marking in the past.Moreover,the campus is modeled in a certain proportion and the user's vision is adjusted by using the mouse and keyboard,so as to serve teachers and students and publicize the campus.Although some universities at home and abroad have started to build their own browsing system,it still has some shortcomings.This article aims at the single status quo of most systems being only the first-person roaming mode and the problem that the development of software requires too much hardware equipment.On the basis of the first-person roaming mode,it is proposed to add third-person roaming mode and drone roaming mode to achieve the purpose of enriching roaming scenarios;In order to solve the problem of heavy burden of hardware equipment,it is proposed to use Blender and Unity 3D software for hybrid modeling and assist in adding grid navigation and pathfinding technology.The purpose of reducing the burden on hardware devices is achieved by reducing the walking of character models and strictly controlling the number and types of veneers.The full text focuses on the research and implementation of virtual campus scenes,takes the real scene of the east campus of Jiangsu University of Science and Technology as an example,uses Blender software as the main modeling tool to complete the building model?character model and terrain model in the virtual campus scene,uses Unity 3D 3D engine as the main development platform and uses UNUI for page design.The main contents of this paper are as follows:(1)Completing the information collection of the overall terrain and buildings of the East Campus of Jiangsu University of Science and Technology and using computer graphics as a design idea,GIS technology and 3D modeling technology,the campus architecture,greening,terrain and other depends on geography The distributed information is processed in 3D visualization,with the help of 3D game software Blender and drawing software Auto CAD to build all building models,local terrain flowers and trees models and character models,bind the character bones,and complete the animation.Optimizing all models such as surface reduction to achieve the final simulation of campus scenes.(2)Adding a third person to the traditional virtual campus system to increase the grid navigation pathfinding roaming mode and drone roaming mode,and adding a fixed-point roaming mode,users can switch to the scene of interest at any time.The drone mode also has the functions of downloading and uploading drone data.(3)The 3D engine based on Unity 3D adds scenes that are still missing from the system and integrates the scenes.Using C # as the development language,through the study of the principle of real-time rendering in virtual reality scenes and the manipulation of entities in the scene and real-time interaction,the campus tour function is realized.This system has interactivity,realism and immersion.Character models stand and walk smoothly and without movements.The phenomenon of wear-through is successfully avoided.The entire scene is successfully integrated with VR to form a complete virtual reality system.The interface interacts smoothly and achieves the intended purpose.
