Design And Implementation Of 3D Interactive Virtual Town Tourism System

In recent years,Chinese tourism industry was developing rapidly,and the scale of the industry continues to expand.In modern life,tourism has become a kind of relief work pressure.But due to the own conditions,economic conditions,and the journey inconvenience,the traditional tourism industry can’t satisfy the people’s need,using a virtual tour of digital information and network technology,the tourism field in a realistic way could present to visitors.Therefore,this paper studies and implements A highly scalable,efficient,and highly portable interactive virtual travel system.Firstly,this paper systematically studies the virtual reality technology and how it is applied to virtual tourism.Then improved and optimized the automatic walking algorithm combining the shortest path algorithm with TSP algorithm.Based on these,it designs and implements an ancient town tourism virtual system 3D-based interactive technology.This system is based on the message mechanism,through the XML file to achieve the integration and configuration of various parameters and modules.Through the analysis of the shortcomings of the online virtual system,a scheme for optimizing the steps of the construction process of the three-dimensional virtual scene is proposed,including the optimization design of the material files,model files,and construction steps.The virtual tourist attraction system is designed in close connection with the cultural and architectural features of Qing Yan Town.Through the simulation scene and the related contents of the scenic culture,combined with the history of the scenic area,the tourists are shown the cultural charm of the ancient town.In the research and design of the algorithm,using the shortest path path-finding algorithm combined with the Way Point method,the user will roams along the shortest path between any two points in the 3D scene.Based on the TSP algorithm,the automatic roaming is optimized,the best path between the generation start point and the reachable destination point is that the user can roam along the route with the most points of interest among any reachable two points in the three-dimensional scene.The effect of roaming is more realistic through the optimization of the roaming process design.This article is based on the above theory,it designs and implements an efficient interactive virtual tour system with powerful functions and automatic roaming.And it has certain theoretical value and application value.Using the UNITY3 D virtualengine to realize the scenic spot scene performance,full three-dimensional perspective to understand the ancient style.Aim at to establish an interactive viewing environment,and connecting with the ancient history,the ancient buildings,ancient town of humanities,becoming available for interaction,combining with the video,pictures,etc.And at the same time harvest about Propylite town natural landscape cultural landscape information platform,playing a supporting role to the tourism development of Propylite.
