Scope

ISO/IEC 19775 Extensible 3D (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 document 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 document does not define physical devices or any other implementation-dependent concepts ( e.g., screen resolution and input devices). This document is intended for a wide variety of devices and applications, and provides wide latitude in interpretation and implementation of the functionality. For example, this document 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, and
can declare additional functional requirements by specifying components.
