Research on the Construction of 3D Virtual Scene Based on Terra Vista

XIA Hongmei;ZHANG Xinjing;ZHANG wenjuan;Training Simulation Center,Naval Marine Academy;  
As the basis of virtual reality,three-dimensional modeling and simulation of virtual scenes technology is paid more and more attention and applied to many fields. In this paper,the method of construction of 3D virtual scene based on terra vista is studied. Firstly,the pow erful speciality of terra vista about terrain modeling and the unique character of creator on the field of 3D modeling are discussed. Then prepared data specifying the process is employed to build a three-dimensional virtual scene. Finally,examples are used to demonstrate the effectiveness of construction of three-dimensional virtual scene w ith terra vista.
