Part 1: Architecture and base components
1 Scope
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. ISO/IEC 19775 does not define physical devices or any other implementation-dependent concepts (e.g., screen resolution and input devices). 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, ISO/IEC 19775 does not assume the existence of a mouse or 2D display device.
Each X3D application:
Part 1 of this specification describes the abstract functional behavior of the X3D system. Part 2 describes the application programmer interfaces (APIs) used to dynamically modify the X3D scene and integrate with external applications. Part 3 specifies various data encoding formats for storing X3D scenes.
