3D Modeling in Virtual Simulation Technology

Virtual reality technology is an emerging multi-disciplinary technology. It provides users with a virtual environment similar to reality, so that users feel immersed in the virtual reality environment. The purpose of this paper is to study the application of 3D modeling in virtual simulation technology. It mainly discusses the modeling and simulation technology based on virtual reality, focuses on the analysis of the generation technology of large-scale terrain, and discusses the modeling method, modeling generation method, dynamic interactive scene generation and information query in VRML environment in detail; Models such as roads and construction machinery are superimposed in the virtual scene containing DEM terrain data; the simulation process of road widening engineering in the road construction scene is realized, the query method in the VRML-based construction scene is analyzed, and the road excavation query block, filling blocks, etc. Finally, using VRML and other virtual reality technologies, the overall analysis and realization of the virtual simulation system of highway construction scene are carried out.
