一、简介 虚拟现实造型语言VRML(VirtualReality Modeling Language)是描述基于通过全球互联网络有多个参加者的交互仿真环境(虚拟世界)的语言。虚拟世界的显示、交互和互联等所有方面都可以用VRML来定义。VRML设计者的意图是将VRML变成WWW上的交互仿真模拟的标准语言。 VRML允许有限的交互行为构造虚拟世界,这些虚拟世界包含有同其它“世界”超链着的对象,诸如超文本置标语言HTML文本或其它有效的MIME(Multipurpose Internet Man Extensions)类型。
I. Introduction Virtual Reality Modeling Language VRML (Virtual Reality Modeling Language) is a language that describes an interactive simulation environment (virtual world) based on multiple participants over the global Internet. All aspects of the display, interaction, and interconnection of the virtual world can be defined using VRML. The intent of VRML designers is to turn VRML into a standard language for interactive simulation on the WWW. VRML allows limited interaction to construct virtual worlds containing objects that are hyperlinked with other “worlds”, such as Hypertext Markup Language HTML or other valid Multipurpose Internet Man Extensions (MIME) types.
