Chapter 14 Virtual reality 14.2 About VrMl 14.2.3 Scope The VRML specification defines a file format that integrates 3d graphics and multimedia. Conceptually, each VRML file is a 3D time-based space 31 that contains graphic and aural objects that can be dynamically modified through a variety of mechanisms. VRML defines a primary set of objects and mechanisms that encourage composition, encapsulation, and extension 领域 VRML规范定义了一种可将3D图形和多媒体结合起来的文件格式。总体 上,每个VRML文件是3维时间依赖空间,包含能够通过不同机制动态修 改的图像和音频对象。VRML定义了一个对象的初始集,并允许将对象 进行合成、封装和扩充。 《什第机专出美语 14-18Chapter 14 Virtual Reality 计算机专业英语 14-18 14.2 About VRML l 14.2.3 Scope The VRML specification defines a file format that integrates 3D graphics and multimedia.
