• 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)

New proposals submitted to H-Anim WG

• 2013-07-21, H-Anim Facial Animation, Prof. Jung-Ju Choi (Ajou Univresity, Korea) FA_HAnim_LA20130721
• 2013-07-21, Modeling and Animation of Hands and Feet, Prof. Kwan-Hee You (Chungbuk National University, Korea) HandAndFeetAnimation130821

Procedure for H-Anim character design

• Procedure for designing an H-Anim character with a general design tool

H-Anim wrl to x3d converter

• Converter from H-Anim WRL to H-Anim X3D

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.

X3D v3.3 specification, H-Anim Component

• version 3.3 Draft International Standard (DIS)
  • http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/components/hanim.html

H-Anim specification, current

• Official version: ISO/IEC 19774:2006 (listed on Web3D Specifications - All Documents)
  • http://www.web3d.org/files/specifications/19774/V1.0/index.html

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.

Humanoid Animation (H-Anim) WG Meeting

• H-Anim WG Meeting at Web3D Conference & SIGGRAPH 2012, Los Angeles, USA, August 3, 2012
• Teleconferences: 1st Wednesday at 9:00am PDT every month
• Our August 2012 meeting will be replaced by the face-to-face H-Anim WG meeting (Hilton Checkers Hotel, 03 August at 16:00).

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

• H-Anim Examples in the X3D Basic Examples Archive

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:

• Web3D members-only H-Anim wiki
• Accommodating Diverse Models (also linked there for members: Proposed amendment to H-Anim Specification)
• Proposed amendment to H-Anim Specification
• TODO list progress and problems
• TODO determine visibility permissions for items on the members-only sites (this is a decision by the working group, assuming that no proprietary information is included)
• TODO find prior working group charter

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

BVH conversion issues

Myeong Won Lee example: http://web3d.org/wiki/images/4/4b/197_a.bvh.txt

Proposed investigation procedure:

1. Is there an X3D H-Anim skeleton that corresponds to the BVH ROOT/JOINT HIERARCHY? Maybe we can build an X3D H-Anim LOA-1 model that has reasonable correspondences:

• HAnimHumanoid - ROOT
• HAnimJoint - JOINT
  • HAnimJoint name - JOINT name
  • center - OFFSET
  • rotation, translation - CHANNEL

2. Once we have the skeleton mapping, we can then build a Script node that takes

• BVH MOTION arrays providing Zrotation Xrotation Yrotation values

to

• corresponding MFRotation arrays with 4-tuple SFRotation values

3. The arrays can then be driven by a TimeSensor and key values at frame-time increments of 0.016667

4. With a little debugging, we can then combine the pieces to show corresponding animations in HAnim and BVH.

Don's recommendation: less talking, more doing. Let's build a paired set of BVH and X3D models.
