This document specifies an image-based representation model that represents target objects/environments using a set of images and optionally the underlying 3D model for accurate and efficient objects/environments representation at an arbitrary viewpoint. It is applicable to a wide range of graphic, virtual reality and mixed reality applications which require the method of representing a scene with various objects and environments. This document:(1) defines terms for image-based representation and 3D reconstruction techniques;(2) specifies the required elements for image-based representation;(3) specifies a method of representing the real world in the virtual space based on image-based representation;(4) specifies how visible image patches can be integrated with the underlying 3D model for more accurate and rich objects/environments representation from arbitrary viewpoints;(5) specifies how the proposed model allows multi-object representation; and(6) provides an XML based specification of the proposed representation model and an actual implementation example (see Annex A).

ISO/IEC 19776-3:2015, Extensible 3D (X3D), defines a system that integrates 3D graphics and multimedia. Conceptually, each X3D file 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 19776 defines a mapping of the abstract objects in X3D to a specific X3D encoding written out in a compact binary form. Each X3D file encoded using the Compressed binary encoding:a. supports all of the purposes of X3D files defined in the X3D abstract specification ISO/IEC 19775; andb. encodes X3D constructs in a compressed binary format, taking advantage of geometric and information-theoretic compression techniques.X3D files encoded using the Compressed binary encoding may be referenced from files using other X3D encodings, and may itself reference other X3D files encoded using other X3D encodings. Sets of X3D files that use multiple encodings can only be processed by browsers that support all of the utilized X3D encodings.

This document describes guidelines for developing education and training systems using VR/AR/MR technology. It defines VR/AR/MR based information modelling that can be used for education and training systems. It provides procedures and methods to be used when developing 3D VR/AR/MR based education and training systems using ISO/IEC JTC 1 standards. It also provides a systematic approach to developing VR/AR/MR based applications for systems integration areas. This work will:- define concepts of VR/AR/MR based education and training.- define an information modelling architecture for VR/AR/MR based education and training systems.- specify standards based functional components for VR/AR/MR based education and training systems.- specify framework components for implementing VR/AR/MR based education and training systems.- include use cases for VR/AR/MR based education and training systems based on the information modelling architecture.Device hardware technology for VR/AR/MR based education and training systems is excluded from this draft.

This document is intended to provide a generic extensible full body image data format for biometric recognition applications requiring exchange of human full body image data. Typical applications are: a) automated body biometric verification and identification of an unknown individual or cadaver (one-to-one as well as one-to-many comparison);b) support for human verification of identity by comparison of individuals against full body images; andc) support for human examination of full body images with sufficient resolution to allow a human examiner to verify identity or identify a living individual or a cadaver.This document ensures that full human body images and image sequence data generated by video surveillance and other similar systems are suitable for identification and verification. The structure of the data format in this document is compatible with ISO/IEC 39794-5. In addition to the data format, this document specifies application-specific profiles including scene constraints, photographic properties and digital image attributes like image spatial sampling rate, image size, etc. These application profiles are contained in a series of annexes. The 3D encoding types "3D point map" and "range image" are not supported by this document.

This document specifies a systematic system for representing humanoids in a network-enabled 3D graphics and multimedia environment. Conceptually, each humanoid is an articulated character that can be embedded in different representation systems and animated using the facilities provided by the representation system. This document specifies the abstract form and structure of humanoids. Further, this document specifies the semantics of humanoid animation as an abstract functional behaviour of time-based, interactive 3D, multimedia articulated characters. This document does not define physical shapes for such characters but does specify how such characters can be structured for animation. This document is intended for a wide variety of presentation systems and applications, providing wide latitude in interpretation and implementation of the functionality.

This document specifies the method of motion capture animation using H-Anim humanoid models. Each humanoid model consists of an articulated character with specified joints and motion capture data. As specified in ISO/IEC 19774-1, each character consists of joints and segments in a hierarchical structure. This document includes the following:(1) Concepts of motion capture as related to humanoid animation,(2) Concepts of motion capture data definition,(3) Definition of motion parameters and motion-capture animation data for transferring or exchanging motion between different humanoid character models,(4) Mapping the structure of motion capture data to the structure of H-Anim objects,(5) HAnim motion capture animation using interpolators,(6) HAnim motion definition using H-Anim Motion objects, and(7) A method for generating and specifying an H-Anim motion capture animation.This document specifies a standard technique for exchanging humanoid animation using motion capture. It does not mandate using any specific run-time system to render the H-Anim characters or animations.

This document specifies extensions to existing scene description formats in order to support MPEG media, in particular immersive media. MPEG media includes but is not limited to media encoded with MPEG codecs, media stored in MPEG containers, MPEG media and application formats as well as media provided through MPEG delivery mechanisms. Extensions include scene description format syntax and semantics and the processing model when using these extensions by a Presentation Engine. It also defines a Media Access Function (MAF) API for communication between the Presentation Engine and the Media Access Function for these extensions. While the extensions defined in this document can be applicable to other scene description formats, they are provided for ISO/IEC 12113.

This document specifies geometry-based point cloud compression.
