摘　　要：对MultiGenCreator和Vega等软件进行二次开发.综合利用虚拟现实(VR)技术、全数字摄影测量系统、地理信息系统(GIS),制作具有真实三维环境的虚拟城市系统.论述基于图像的建模与绘制(Image-BasedModelingandRendering,IBMR)等获取虚拟模型的技术,把CAD,3DSMAX和Imagis软件的模型,转换到MultiGen以及处理纹理的技术.The softwares including MultiGen Creator and vega were developed here secondarily. By comprehensive utilization of virtual reality technique, all-number photography and measurement system, and geographic information system, the authors made a virtual city system with true 3D environment. They also discussed the techniques for obtaining virtual model such as image-based modeling and rendering; the technique for transforming the models of CAD, 3DSMAX and images software into MultiGen, and the technique for processing texture.
