This document defines the scope and key concepts of mixed and augmented reality, the relevant terms and their definitions and a generalized system architecture that together serve as a reference model for mixed and augmented reality (MAR) applications, components, systems, services and specifications. This architectural reference model establishes the set of required sub-modules and their minimum functions, the associated information content and the information models to be provided and/or supported by a compliant MAR system. The reference model is intended for use by current and future developers of MAR applications, components, systems, services or specifications to describe, compare, contrast and communicate their architectural design and implementation. The MAR reference model is designed to apply to MAR systems independent of specific algorithms, implementation methods, computational platforms, display systems and sensors or devices used. This document does not specify how a particular MAR application, component, system, service or specification is designed, developed or implemented. It does not specify the bindings of those designs and concepts to programming languages or the encoding of MAR information through any coding technique or interchange format. This document contains a list of representative system classes and use cases with respect to the reference model.

The document is the first of a family of standards. ISO/IEC 14478 specifies techniques for supporting interactive Single, and multiple media applications which recognize and emphasize the interrelationships among user interfaces, multimedia applications, and multimedia information interchange. ISO/IEC 14478 defines a flexible environment to encompass modular functionality and is extensible through the creation of future components, both within and outside of Standards committees. It supports a wide range of multimedia applications in a consistent way, from simple drawings up to full motion Video, Sound, and virtual reality environments. ISO/IEC 14478 is independent of any particular implementation language, development environment, or execution environment. For integration into a programming environment, the Standard shall be embedded in a System dependent interface following the particular conventions of that environment. ISO/IEC 14478 provides versatile packaging techniques beyond the capabilities of monolithic Single-media Systems. This allows rearranging and extending functionality to satisfy requirements specific to particular application areas. ISO/IEC 14478 is developed incrementally with Parts 1 through 4 initially available. Other components are expected to be standardized by ISO/IEC JTC 1 SC24 or other subcommittees. ISO/IEC 14478 provides a framework within which application-defined ways of interacting with the environment tan be integrated. Methods for the definition, presentation, and manipulation of both input and output objects are described. Application-supplied structuring of objects is also allowed and tan, for example, be used as a basis for the development of toolkits for the creation of, presentation of, and interaction with multimedia and hyper-media documents and product model data. ISO/IEC 14478 is able to support construction, presentation, and interaction with multiple simultaneous inputs and Outputs using multiple media. Several such activities may occur simultaneously, and the application program tan adapt its behaviour to make best use of the capabilities of its environment. ISO/IEC 14478 includes interfaces for external storage, retrieval and interchange of multimedia objects.

ISO/IEC 15948:2004 specifies a datastream and an associated file format, Portable Network Graphics (PNG, pronounced 'ping'), for a lossless, portable, compressed individual computer graphics image transmitted across the Internet. Indexed-colour, greyscale, and truecolour images are supported, with optional transparency. Sample depths range from 1 to 16 bits. PNG is fully streamable with a progressive display option. It is robust, providing both full file integrity checking and simple detection of common transmission errors. PNG can store gamma and chromaticity data as well as a full ICC colour profile for accurate colour matching on heterogenous platforms. ISO/IEC 15948:2004 defines the Internet Media type "image/png". The datastream and associated file format have value outside of the main design goal.

This document is the first of a family of standards. It specifies a set of functions for computer graphics programming, the graphical kernel system. Provides functions for two dimensional graphical output, the storage and dynamic modification of pictures, and operator input. Applicable to a wide range of applications that produce two dimensional pictures on vector or raster graphical devices in monochrome or colour.

This document is the first of a family of standards. ISO/IEC 8632 provides a file format suitable for the storage and retrieval of picture description information. The file format consists of an ordered set of elements that may be used to describe pictures in a way that is compatible between systems of different architectures, compatible with devices of differing capabilities and design, and meaningful to application constituencies. This picture description includes the capability for describing static images. The elements specified provide for the representation of a wide range of pictures on a wide range of graphical devices. The elements are organized into groups that delimit major structures (metafiles, pictures, and application structures), that specify the representations used within the metafile, that control the display of the picture, that perform basic drawing actions, that control the attributes of the basic drawing actions, that allow application-specific structuring to be overlaid on the graphical content, and that provide access to non-standard device capabilities. The metafile is defined in such a way that, in addition to sequential access to the whole metafile, random access to individual pictures and individual context-independent application structures is well-defined. Applications which require random access to pictures and/or context-independent application structures within pictures may, within the metafile, define directories to these pictures and/or context-independent application structures. The metafile may then be opened and randomly accessed without interpreting the entire metafile. In addition to a functional specification, two standard encodings of the metafile syntax are specified. These encodings address the needs of applications that require small metafile size plus minimum effort to generate and interpret, and maximum flexibility for a human reader or editor of the metafile. This part of ISO/IEC 8632 describes the format using an abstract syntax. The remaining parts of ISO 8632 specify standardized encodings that conform to this syntax: ISO/IEC 8632-3 specifies a binary encoding; ISO/IEC 8632-4 specifies a clear text encoding.

This document is the first of a family of standards. ISO/IEC 9636 establishes the conceptual model, functional capability, and minimum conformance requirements of the Computer Graphics Interface (CGI). It specifies design requirements for encodings of the CGI. ISO/IEC 9636 defines a set of CGI functions that is expected to satisfy the following needs of a majority of the computer graphics community:

(a) provide an interface standard for computer graphics software package implementors;

(b) provide an interface standard for computer graphics device manufacturers and suppliers;

(c) provide an inquiry and response mechanism for graphics device capabilities, characteristics, and states;

(d) provide a standard graphics escape mechanism to access non-standard graphics device capabilities; and

(e) allow for future functional extension of the CGI.

In addition to the CGI functionality, device classes, and Foundation and Constituency Profiles are defined. The device classes included in the CGI are output (OUTPUT), input (INPUT), and output/input (OUTIN). Profiles allow subsets of the CGI functions and features to be defined to suit particular well-identified groups of users. There is also provision for Constituency Profiles to be registered after ISO/IEC 9636 is published. The Computer Graphics Interface (CGI) is a standard functional and syntactical specification of the control and data exchange between device-independent graphics software and an implementation of a CGI Virtual Device. The syntax of the CGI, presented in ISO/IEC 9636, is an encoding-independent and binding-independent specification. Any similarity of the examples or function specifications to a particular encoding technique or language is coincidental unless explicitly stated otherwise. The functions specified provide for the representation of a wide range of two-dimensional pictures and for control over their display on a wide range of graphics devices. The functions are split into groups that perform device and CGI session control, specify the data representations used, control the display of the picture, perform basic drawing actions, control the attributes of the basic drawing actions, acquire data from input devices, and provide access to non-standard device capabilities. This part of ISO/IEC 9636 gives an overview of ISO/IEC 9636, explains the relationship between its parts and their relation to other standards, describes a reference model for graphics systems, and defines certain Foundation and Constituency Profiles. ISO/IEC 9636-2, ISO/IEC 9636-3, ISO/IEC 9636-4, ISO/IEC 9636-5, and ISO/IEC 9636-6 specify the CGI functions for different functional areas using an abstract notation. ISO/IEC 9637 and ISO/IEC 9638 define standard data stream encodings, procedural library bindings, and single entry point procedural bindings of the CGI.

ISO/IEC 9973:2013 specifies procedures to be followed in preparing, maintaining and publishing the International Register of Items for any standard whose classes of items are applicable to this register. The items that may be registered fall into several broad categories including:

- computer graphics concepts,

- data structures used by relevant standards,

- spatial and environmental concepts, and

- profiles of relevant standards.

This document is the first of a family of standards. ISO/IEC 12087 is concerned with the manipulation, processing, and interchange of all types of digital images. The main purpose of this part is to define a generic, unifying imaging architecture to which other parts of ISO/IEC 12087 conform. This part of ISO/IEC 12087 also defines those specializations or delineations of the generic imaging architecture that are required to support IPI-PIKS and IPI-IIF.

This document defines a set of concepts and their inter-relationships which should be applicable to the complete range of future computer graphics standard. May be applied to verify and refine requirements for computer graphics; to identify needs for computer graphics standards and external interfaces; to develop models based on requirements for computer graphics; to define the architecture of new computer graphics standards; compare computer graphics standards.

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:

(1) implicitly establishes a world coordinate space for all objects defined, as well as all objects included by the application;

(2) explicitly defines and composes a set of 3D and multimedia objects;

(3) can specify hyperlinks to other files and applications;

(4) can define programmatic or data-driven object behaviours;

(5) can connect to external modules or applications via programming and scripting languages;

(6) explicitly declares its functional requirements by specifying a profile; and

(7) can declare additional functional requirements by specifying components.
