Abstract

Virtual Reality technology is used to design a lifelike virtual environment based on the computer technology, which can access interaction between the user and the environment by use of the essential device. At present, the virtual reality technology as one of digital globe’s key technologies is being applied to more and more areas, such as entertainment, medical service, education and training, project and building, science and financial visualization.

Based on the simulation and analysis of the airport environment, this paper gives a visual scene simulation solution based on MultiGen Creator and Vega. This paper describes Three-Dimensional (3D) simulation scene construction technology based on MultiGen Creator，and shows the drawings after the implementation of plans. After finishing the construction of scenes, this paper then describes the scene roaming program which is developed with Vega platform to construct 3D scenes, also the detail technology line and implementation methods about how to use this platform to construct 3D scene simulation program.

Keywords: Virtual Reality, Airport simulation, View of the roaming
