NWIP's scope and responsibility

Please add responsible persons for each item. We recommend that the persons of responsibility work on draft and/or examples for conformance.

  • 1) Definition of a humanoid character model capable of generating motion from captured motion data → Myeong and Joe
  • 2) Definition of a humanoid character model capable of generating motion using 3D scanner data → Myeong and William
  • 3) Definition of a humanoid character model capable of generating motion using a general motion definition such as keyframe, interpolation, kinematics, and dynamics for human figures → Myeong and Joe
  • 4) Definition of motion parameters for transferring or exchanging motion between different human character models → Myeong and Dick
  • 5) Definition of a motion data interface for including motion data → Myeong and Dick
  • 6) Definition of a motion viewer’s functionality → Myeong and Joe
  • 7) Definition of interoperable human behavior prototypes → Don, Myeong and William
  • 8) Guidelines for adding 3D skinning to humanoid characters → Joe and Don
  • 9) Definition of a recording interface for human motion such as gait → Don and William
  • 10) Provision for easier exchange of characters from design systems to H-Anim systems. → Myeong and Joe

This work is intended to define a standard model for humanoid animation including motion interfaces. It is an enhancement to the original H-Anim model of ISO/IEC 19774, and ISO/IEC 19774 Working Draft Amendment (WDAM) 1 in progress.

Document plan

  • The motion-related work is expected to be integrated with the 19774 specification and the 19774 WDAM 1 documents into a new document.
  • It may become appropriate and necessary to split the revised 19774 specification into multiple parts.

Formal submission of the H-Anim NWIP to ISO depends on working-group preparation of

  • Initial Committee Draft (CD) specification text
  • At least one draft implementation (with plans for a second)
  • Working examples, validation, quality assurance (QA)

Previous work

Resources

H-Anim Behavior Prototypes

Prototypes for HAnimBehavior node, which collects OrientationInterpolators for aggregate animation of an H-Anim humanoid model, and

HAnimBodyBehaviorChooser, which selects one body and enables/disables multiple aggregate behaviors.

H-Anim examples designed with a general tool (10 H-Anim characters)

Standards Development: Specifications

Two primary specifications govern this work: the X3D and the H-Anim International Standards. The H-Anim standard describes functional information in full detail, while the X3D specification simply references this work and maps constructs into X3D nomenclature. Working group members: only refer to the official version as we confirm current capabilities and rejuvenate future work.

H-Anim specification, current

H-Anim specification, incomplete draft change

  • H-Anim Working Draft Amendment WDAM1
    • http://igraphics.com/Standards/ISO_IEC_19774_WAM1_2009_01_12/index.html
    • This draft amendment proposed new capabilities for H-Anim and is a reasonably complete document.
    • It was never approved by Web3D Consortium nor submitted to ISO.
    • We are interested in learning whether any implementations exist that demonstrate these proposed changes.
    • It stalled when working group activity ceased circa January 2009.
    • Added items in this draft "change document" can be reconsidered by the reactivated working group.

Use Cases

Working Group chairs keep the following pages up to date:

  • We estimate there are upwards of 1,000 H-Anim Use Cases to fully characterize the human experience from the time all the bones of a human are formed or developed through

final disposition of the human body (mummification, cremation, burial, etc.). The vocabulary for human behavior (including misbehaving in all cultures, societies, etc.) serves as our baseline. Ontologies, taxonomies, classifications, encyclopedia and handbooks for human behavior are starting points for deriving the skeletal and skin motions for each concept, term and are categorized by:

1. duration of animation (measured in seconds: 3 - 30,000) 2. total joint angle displacement (displacement spectrum-percent of total possible displacement per joint) 3. angular rate of displaced joints (displacement speed spectrum - percent of maximum displacement) 4. simultaneity of joint displacement (percent of total joints in motion)

Moreover, this Working Group shall bin Use Cases in to those the WG are 1) likely to prototype 2) not likely to prototype and 3) will not prototype.

The complexity and duration of H-Anim scenes will correlate with the (actions) terms, (motions) concepts and (movements) behaviors of humans in natural and man-made environments with and without constraints of hand-held objects, clothing, etc.

Below are sample H-Anim Customer Segments (Authors and Consumers):

  • Use Cases (titles only) by Customer Segment (Authors and Consumers):

Current Work

Working group chairs keep the following pages up to date:

Joe and Don are working each Monday night [1700-1900 pacific, Web3D teleconference line) on

  • As those issues get sorted out, we are re-visiting all the important details regarding H-Anim skinning
    • Definitions, example test scenes, tool support
    • Proposing an improved H-Anim component for X3D v3.4
    • Editing a corresponding update to H-Anim ISO 19774 Specification

The larger group is also working on

  • interoperable, swappable behaviors
  • motion capture
  • facial animation

Humanoid Animation (H-Anim) WG Meeting

March 2012: H-Anim Working Group Draft Charter materials by Web3D Korean Chapter

Links of interest:

There has been previous work by the H-Anim working group during 2008-2009 that was not completed. Here are some additional links on the members-only wiki:

Much additional work has been proposed by the Korea Chapter.

  1. Definition of a humanoid character model capable of generating motion from captured motion data
  2. Definition of a humanoid character model capable of generating motion using a general motion definition such as keyframe, interpolation, kinematics and dynamics for human figures.
  3. Definition of motion parameters for transferring or exchanging motion between different human character models
  4. Definition of motion data interface for including motion data
  5. Definition of behavior modeling data
  6. Definition of motion viewer’s functionality
  7. Video human functionality and gestures will be considered in AR/MR working group efforts

We agreed on the 1 Feb 2012 teleconference that it is a good idea to document work on these many good ideas using this H-Anim public wiki. Further comment is welcome about this.

The main thing that is needed next is to get the H-Anim Working Group restarted and rejuvenated.

  • H-Anim WG Charter
  • TODO: we need 1-2 members who are willing to volunteer to serve as working group co-chairs.
  • Working Draft for the H-Anim motion definition (in preparation) H-Anim Motion Definition
