ISO/IEC 19775-1:2013 PDF

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. ISO/IEC 19775-1:2013 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 19775-1:2013 does not define physical devices or any other implementation-dependent concepts (e.g. screen resolution and input devices). It is intended for a wide variety of devices and applications, and provides wide latitude in interpretation and implementation of the functionality. For example, it 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.
