标准简介：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. This part of ISO/IEC 19775 defines the architecture and base components of X3D.
The semantics of X3D describe an abstract functional behaviour of time-based, interactive 3D, multimedia information. This part of ISO/IEC 19775 does not define physical devices or any other implementation-dependent concepts (e.g., screen resolution and input devices). THis part of ISO/IEC 19775 is intended for a wide variety of devices and applications, and provides wide latitude in interpretation and implementation of the functionality. For example, this part of ISO/IEC 19775 does not assume the existence of a mouse or 2D display device.
Each X3D application:
a. implicitly establishes a world coordinate space for all objects defined, as well as all objects included by the application;
b. explicitly defines and composes a set of 3D and multimedia objects;
c. can specify hyperlinks to other files and applications;
d. can define programmatic or data-driven object behaviours;
e. can connect to external modules or applications via programmingand scripting languages;
f. explicitly declares its functional requirements by specifying a profile;
g. can declare additional functional requirements by specifying components.
