Design And Implementation Of Laboratory Virtual Roaming System Based On Unity3D

As a hotspot in the field of information technology research,virtual reality is becoming more and more applied to people's life with the development of computer graphics and hardware.Through the use of 3d visualization and virtual reality interactive technology,the laboratory virtual Roaming system is built,which combines the display and sightseeing functions of the laboratory.For schools and scientific research institutions,not only can show the lab research direction and the scientific research strength,and to attract high-quality talents to join in for scientific research and innovation has a good role in promoting.In this paper,the research and design of laboratory virtual roaming system,allows users to experience personally to the scene roaming,learn about lab information,at the same time interactive design for the user to add interesting and realistic.This article in view of the existing virtual roaming system widely used PC as the characteristics of the display platform,combining with the project development objectives and actual meaning,determine the use of intelligent mobile phone as a laboratory virtual roaming system display terminal.On the basis of simple geometric modeling and image modeling,combining both advantages,put forward modeling using mixed modeling technology.Using 3dsMax to build virtual scene model and make a good model for texture rendering,complete laboratory roaming system scene modeling.The features of each software platform developed by virtual reality interactive function are analyzed comprehensively,and Unity3D game engine is determined as the development platform of virtual roaming system.According to existing virtual roaming system development,the status quo of interactivity is less,the project is in the system increase a lot of interactive design,and development of the laboratory monitoring system,implements the interoperability of virtual roaming system and monitoring equipment.Finally,the application is deployed to the server,and the software can be downloaded via a fixed URL,which facilitates the virtual roaming of more users.The main contents of this paper are as follows:(1)In this paper,the research status of virtual reality is analyzed,and the theoretical significance and practical value of the thesis are proved by combining with the development background of virtual reality technology.(2)Through the comparison of the current virtual tour system development,this paper demonstrates the advantages of the interaction design and the deployment of the virtual tour system to the server.By comparing the three dimensional modeling technology and system interaction design platform features,determine the using geometrical modeling and image modeling both the advantage of hybrid modeling technology to build the scene model using Unity3D game engine as interactive function development platform,and visibility of system development involves cutting technology,collision detection technology and theoretical analysis on the key techniques such as 3D pick up technology.(3)Completed the laboratory data acquisition and processing of the virtual scene roaming system,using geometric modeling to construct the main outline of the object,using graphics rendering and rendering technology to highlight the details of the object.Using the hybrid modeling technique to create the scene stereo feeling strong,the display effect is real.(4)To design automatic roaming and manual roaming for the roaming system,the collision detection technology and visibility cutting technology are realized,and the background music can be set.A large amount of interactive design is added to the system design,mainly include interactive object prompt message,scene transmission,information display,internet access to object information and control mobile objects,pick up objects,switch control computer and video resources play and the scene lighting control and so on interactive function design.The laboratory monitoring system is developed,and the interoperation of virtual system and laboratory monitoring equipment is realized.(5)The system is released into the mobile APP,and the application is configured to the ALiYun server.The software is downloaded from the fixed website,and the system is tested on the computer terminal Unity3D development platform and mobile phone.This paper mainly uses hybrid modeling technology,using 3dsMax modeling software,the roaming system scene model is created,and the mapping rendering is carried out,and the virtual scene with high similarity with the real scene is constructed.Using the Unity3D game engine to design and implement interactive functions such as character roaming and walking,information display,scene transmission,pick up objects,and interoperation with laboratory monitoring equipment in the virtual roaming system.The design of these interaction modes enriches the system functions and adds the authenticity of the user's roaming experience.Finally,the system APP release and server side deployment are completed,so that the roaming system can be downloaded and used by more users.
