摘　　要：虚拟现实技术已广泛应用社会各个领域。X3D作为VMRL语言的继承版本,增加了很多新的特点。文中以X3D建模为工具,在分析了X3D的特点和语法的基础上,结合现有的虚拟现实技术对大范围三维虚拟场景的开发原理和技术进行了研究。最后给出了一应用实例。The virtual reality technology has been widely used in each field of the society.To be the next-generation of VRML,X3D improves upon VRML97 with new features.Based on analyzing the characteristics and syntax of X3D and combing the existing virtual reality technology,the development principle and technology to construct the large scale 3D terrain scene are studied based on X3D.Finally,one case study is presented.
