标准摘要
[中文适用范围]: ISO/IEC 19775(X3D)定义了集成支持网络的 3D 图形和多媒体的软件系统。 从概念上讲,每个 X3D 应用程序都是一个基于时间的 3D 空间,其中包含可以通过各种机制动态修改的图形和听觉对象。 ISO/IEC 19775 的这一部分定义了 X3D 的架构和基本组件。 X3D 的语义描述了基于时间的交互式 3D 多媒体信息的抽象功能行为。 ISO/IEC 19775 的这一部分没有定义物理设备或任何其他依赖于实现的概念(例如,屏幕分辨率和输入设备)。 ISO/IEC 19775 的这一部分适用于各种设备和应用,并在功能的解释和实现方面提供了广泛的自由度。 例如,ISO/IEC 19775 的这一部分不假设鼠标或 2D 显示设备的存在。 每个 X3D 应用程序:为所有定义的对象以及应用程序包含的所有对象隐式建立世界坐标空间; b.明确定义并组成一组 3D 和多媒体对象; C。 可以指定其他文件和应用程序的超链接; d.可以定义编程或数据驱动的对象行为; e.可以通过编程和脚本语言连接到外部模块或应用程序; F。 通过指定配置文件明确声明其功能需求; G。 可以通过指定组件来声明附加的功能需求。 [外文原描述]: ISO/IEC 19775-1:2004 defines the architecture and base components of X3D. ISO/IEC 19775, X3D, defines a software system that integrates network-enabled 3D graphics and multimedia. Conceptually, each X3D application is a 3D time-based space that contains graphic and aural objects that can be dynamically modified through a variety of mechanisms. The semantics of X3D describe an abstract functional behaviour of time-based, interactive 3D, multimedia information. ISO/IEC 19775-1:2004 does not define physical devices or any other implementation-dependent concepts (e.g. screen resolution and input devices). ISO/IEC 19775-1:2004 is intended for a wide variety of devices and applications, and provides wide latitude in interpretation and implementation of the functionality. For example, ISO/IEC 19775-1:2004 does not assume the existence of a mouse or 2D display device. Each X3D application: implicitly establishes a world coordinate space for all objects defined, as well as all objects included by the application; explicitly defines and composes a set of 3D and multimedia objects; can specify hyperlinks to other files and applications; can define programmatic or data-driven object behaviours; can connect to external modules or applications via programming and scripting languages; explicitly declares its functional requirements by specifying a profile; can declare additional functional requirements by specifying components.
