Full title and description

ISO/IEC 19774:2006 — Information technology — Computer graphics and image processing — Humanoid Animation (H-Anim). This International Standard specifies a systematic, abstract method for representing humanoid (articulated) characters for use in network-enabled 3D graphics and multimedia environments; it defines the form and structure of humanoids and the semantics needed to animate them across different representation systems.

Abstract

ISO/IEC 19774:2006 defines an abstract model for humanoid figures (humanoids) consisting of objects such as Humanoid, Joint, Segment, Site and Displacer, together with conventions for modelling, articulation, and animation semantics so that humanoid models and motion data can be exchanged and reused across tools and run-time systems. The standard provides bindings (informative/ normative annexes) for representation systems such as VRML and X3D and includes conformance rules and recommended body dimensions and feature points for interoperability.

General information

• Publisher: International Organization for Standardization (ISO), in cooperation with IEC/ISO JTC 1/SC 24.
• ICS / categories: 35.140 (Computer graphics and image processing).
• Edition / version: Edition 1.0 (2006).
• Number of pages: ~8 pages (published edition indicated as 8 pages in ISO catalogue entry).

Scope

The standard addresses representation and animation of humanoid figures for a wide variety of presentation systems and applications. It specifies an abstract structure for humanoids (hierarchy of humanoid → joints → segments → sites → displacers), conventions for modelling (pose, coordinate axes, reference posture), and interfaces/bindings so that animations and motion-capture data can be applied to and exchanged between different humanoid models and run-time systems. It does not mandate concrete visual shapes but ensures model interoperability and consistent semantics for animation.

Key topics and requirements

• Abstract object model: definitions of Humanoid, Joint, Segment, Site and Displacer and their relationships.
• Hierarchy and coordinate conventions: root Humanoid placement, default pose and axis orientation to ensure consistent articulation and retargeting.
• Kinematics and articulation: joint axes, degrees of freedom, and conventions for joint transforms and segment attachment.
• Modeling rules for interoperability: recommended body dimensions, feature points, and levels of articulation to maximize reuse of animations.
• Bindings and encodings: mappings to representation systems (VRML and X3D bindings are specified in annexes) so H-Anim can be embedded in common 3D formats.
• Conformance and use cases: conformance clauses and guidance for using H-Anim in motion-capture exchange, playback and run-time systems.

Typical use and users

Authors of 3D content (modelers and riggers), motion-capture studios, animation tool and game engine developers, VR/AR content creators, researchers and software implementers concerned with exchanging humanoid geometry and motion data between systems. H-Anim is used where interoperable skeleton/rig definitions and motion-transfer semantics are required.

Related standards

ISO/IEC 19774 was revised and split into ISO/IEC 19774-1:2019 (HAnim architecture) and ISO/IEC 19774-2:2019 (HAnim motion data / motion-capture animation). H-Anim bindings and usage are closely related to VRML (ISO/IEC 14772-1), X3D family standards (ISO/IEC 19775, ISO/IEC 19776, etc.), and other Web3D and graphics interchange standards that address scene graph, component and encoding mappings. Implementers commonly consult the X3D/H-Anim component mappings and the Web3D Consortium resources for practical specification texts and examples.

FAQ

Q: What is this standard?

A: ISO/IEC 19774:2006 (Humanoid Animation, H-Anim) is an international standard that defines an abstract model and conventions for representing and animating humanoid figures so animations and motion data can be shared across different 3D systems and tools.

Q: What does it cover?

A: It covers the abstract object model (Humanoid, Joint, Segment, Site, Displacer), coordinate and pose conventions, modelling recommendations for interoperability, conformance requirements, and bindings to representation systems (VRML and X3D annexes). It provides the semantics needed to apply and exchange motion/capture data between humanoid models.

Q: Who typically uses it?

A: 3D modelers and riggers, motion-capture facilities, animation tool and engine developers, and anyone needing a standard skeleton/rig and motion-exchange format for humanoid characters.

Q: Is it current or superseded?

A: The 2006 edition has been withdrawn and superseded by a revised two-part publication: ISO/IEC 19774-1:2019 (HAnim architecture) and ISO/IEC 19774-2:2019 (HAnim motion data / motion-capture animation). For new implementations and references, use the 2019 parts.

Q: Is it part of a series?

A: Yes — the H-Anim work is now published as a multipart standard (19774-1 and 19774-2, 2019). It also relates to the X3D and VRML families (ISO/IEC 19775, ISO/IEC 19776 and ISO/IEC 14772-1) for concrete bindings and scene representation.

Q: What are the key keywords?

A: H-Anim, humanoid, joint, segment, skeleton, motion capture, interoperability, VRML, X3D, ISO/IEC 19774.
