(Our meeting today is hosted by Myeong Won Lee and the Web3D Korea Chapter. Thank you - ham sa ham ni dah!)

Overview. Lots of activity continues to gradually proceed in H-Anim. These lists of suggested steps can help us stay organized and productive.


  • Static position/posture poses
  • Corresponding Displacer nodes
  • Composition of partial behaviors
    • Additive (e.g. waving + sitting down)
    • Superposition(e.g. waving + walking)
  • Behavior libraries
    • Inline and IMPORT/EXPORT conventions
    • LOA by LOA


Examples are always a powerful way to show whether the specification is working or needs improvement.

Additional Examples Needed

  • Anatomically correct human
  • Animals
  • Cartoon charchers (humanoid but not human)
  • Clothing
  • Conversion of BVH examples
  • Skin (we will add Joe's examples, as they are tested)

Human Skeleton

Korean Characters

  • prepared by MWL and students, excellent cartoon characters
  • Joints/Segments and skin, H-Anim compliant, LOA?
  • TODO add to Basic archives, find/review prior list of requested fixes

H-Anim Specification

  • LOA 5 for all remaining animatable joints in human body? Discussion please
  • Names for Joints, Segments, Sites


BVH Converter

  • Algorithm
  • MWL's C++ code, described in slides, final fixes needed
  • DPB to consider writing corresponding Java code


  • What is the name of this tool please?
  • Can we announce availability?
  • Excellent and novel capabilities - TODO list
  • Can produce sophisticated animations

X3D Decorator

  • New, under development
  • XSLT stylesheet can follow "decorator pattern" to modify scene graphs
    • Converts .x3d to a modified .x3d
  • Current support for canonical form, omitting default values, url corrections, minor fixups
  • TODO add support for H-Anim
    • remove geometry from Joints/Segments/Sites
    • Add/replace geometry to Joints/Segments/Sites

X3D Schematron Validation

  • X3D Schematron includes numerous validation rules
    • TODO list them?
  • Are asymmetry warnings helpful?
  • Still need rules for skin
  • Lists of additional joint, segment, site names
