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.

Current Work

Working group chairs keep the following pages up to date:

• Humanoid Animation (H-Anim) overview on web3d.org site
• This wiki page

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

• Confirming first the status of all current work relative to the approved H-Anim Specification
  • X3D Basic Examples for H-Anim
  • X3D tooltips, X3D DOCTYPE Documentation and X3D Schema Documentation for the H-Anim nodes
  • X3D Player Support for H-Anim
  • X3D Authoring Tool Support for H-Anim including X3D-Edit
  • X3D Quality Assurance (QA) and X3D Validator

• 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

This wiki page is the site for the recently renewed Humanoid Animation (H-Anim) Working Group.

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

Links of interest:

• H-Anim Executive Summary for more Working Group information
• H-Anim working group
• Humanoid Animation V1.0 Specification (.zip)
• 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

William's Section!

Human joint articulation of any type (there are six: ball & socket, elbow, gliding, hinge, hip, and saddle joints) can be expressed using Euler angles or quaternions. The word quaternion is modified based on how it is used--rotation, orientation or attitude modifiers are germane but there are others for different use cases. There are multiple approaches to convert Euler angles into quaternions (http://en.wikipedia.org/wiki/Hamilton_product#Hamilton_product, http://en.wikipedia.org/wiki/Quaternions_and_spatial_rotation).
