Comparison of 3D Scene Construction Technologies in Virtual Tourism

This paper studies the 3D scene construction technologies in virtual tourism and analyzes the models and display technology of typical tourism systems at home and abroad. Based on the analysis, it evaluates the systems as a whole and summarizes the problems in the three aspects of the current virtual tourism services: display effect, human-machine interface, and operation model. Moreover, through the comparative analysis of approaches to obtaining material, production difficulty, real-time performance, interactivity level, and other indicators in the implementation of the modeling technology involved in 3D scene construction, this paper proposes a scheme for selecting modeling methods for scene construction based on different needs. In the end, through the comparative analysis of mainstream modeling software in terms of real-time rendering, model fineness, interactivity, and data volume, the paper identifies the software suitable for building complex and simple scenes, providing new solutions and ideas for the development and application of virtual tourism services.
